Full textAbstract:
Cacopsylla fraudatrix Labina & Kuznetsova sp.n., collected from Vaccinium myrtillus in Bieszczady Mountains (S. Poland) is described and compared with the most closely related species, C. myrtilli (developing on V. myrtillus) and C. ledi (on Ledum palustre) as well as with a distantly related species C. vaccinii (on V. bracteatum). The identity of the new species is supported by the structure of testes consisting of two follicles each, in contrast to four in C. myrtilli and C. ledi, and by a molecular phylogenetic analysis based on a 714 bp fragment of the mitochondrial COI gene. C. fraudatrix sp. n. forms a distinct clade in MP, ML and BI trees and differs from C. myrtilli by 28 fixed nucleotide substitutions (uncorrected p-distance = 3.92%) and from C. ledi by 26 fixed nucleotide substitutions (uncorrected p-distance = 3.64%).

Цель исследования – актуализация и конкретизация ранее разработанного метода количественной оценки запасов лекарственных растений в ходе смен растительности под влиянием сплошных рубок. Для каждого типа лесорастительных условий (ЛРУ) была выявлена динамика проективного покрытия лекарственных растений, встречающихся в его лесах с преобладанием разных пород и разных стадий восстановительной динамики после рубок. На основе корреляционных зависимостей установлена фитомасса заготавливаемых частей растений для всех типов леса и стадий восстановительной динамики, их биологический и эксплуатационнный запасы. В лесах брусничного и лишайникового типов ЛРУ обильны Calluna vulgaris, Cetraria islandica, Arctostaphylos uva-ursi. В сосняках брусничных возможна заготовка брусники (Vaccinium vitis-idaea), а в ельниках брусничных черники (Vaccinium myrtillus). На нормально дренированных суглинках и двучленных наносах в черничном и кисличном типах ЛРУ постоянно встречаются Majanthemum bifolium, Oxalis acetosella, Vaccinium myrtillus и Vaccinium vitis-idae. После рубки обилие этих видов (кроме брусники) снижается, на вырубках и в молодняках доминантами становятся такие лекарственные растения, как Rubus idaeus, Chamaenerion angustifolium. Значительное количество лекарственных видов встречается в болотных и заболоченных багульниковых и сфагновых лесах (Vaccinum myrtillus, Calluna vulgaris, Ledum palustre, Eriophorum vaginatum, Vaccinium vitis-idaea). В лесах проточного ряда увлажнения встречаются Athyrium filix-femina, Filipendula ulmaria, Aconitum septentrionale, Aegopodium podagraria, Pulmonaria officinalis, Urtica dioica. Athyrium filix-femina, Filipendula ulmaria, Equisetum sylvaticum, Lysimachia vulgaris, Menyanthes trifoliata, Comarum palustre. The purpose of the study is to update and concretize the previously developed method of quantifying stocks of medicinal plants during vegetation shifts under the influence of continuous logging. For each type of forest growing conditions (LRU), the dynamics of the projective covering of medicinal plants found in its forests with the predominance of different breeds and different stages of recovery dynamics after logging were revealed. On the basis of correlation dependencies, the phytomass of harvested plant parts for all types of forests and stages of regenerative dynamics, their biological and operational reserves have been established. Calluna vulgaris, Cetraria islandica, Arctostaphylos uva-ursi are abundant in forests of cranberry and lichen types of LRU. In cranberry pine forests, it is also possible to harvest cranberries (Vaccinium vitis-idaea), and in cranberry spruce forests, blueberries (Vaccinium myrtillus) are also possible. On normally drained loams and binomial deposits in blueberry and sour types of LRU. Majanthemum bifolium, Oxalis acetosella, Vaccinium myrtillus and Vaccinium vitis-idae are constantly found in forests of these types. After logging, the abundance of these species (except cranberries) decreases, such medicinal plants as Rubus idaeus, Chamaenerion angustifolium become dominant in cuttings and in young plants. A significant number of medicinal species are found in swampy and swampy bagulnik and sphagnum forests (Vaccinum myrtillus, Calluna vulgaris, Ledum palustre, Eriophorum vaginatum, Vaccinium vitisidaea). Athyrium filix-femina, Filipendula ulmaria, Aconitum septentrionale, Aegopodium podagraria, Pulmonaria officinalis, Urtica dioica are found in the forests of the humidification flow range. Athyrium filix-femina, Filipendula ulmaria, Equisetum sylvaticum, Lysimachia vulgaris, Menyanthes trifoliata, Comarum palustre.

Full textAbstract:
Communities of Loiseleurio procumbentis–Vaccinietea Eggler ex Schubert 1960 class and Deschampsio flexuosae–Vaccinietalia myrtilli Dahl 1957 order, widespread in the East European tundras, are represented by 2 alliances: Loiseleurio-Arctostaphylion Kalliola ex Nordhagen 1943 (dwarf-shrub-lichen communities in wind-blown habitats with well-drained automorphic soils) and Phyllodoco–Vaccinion myrtilli Nordhagen 1943 (moderately chionophytic dwarf-shrub communities in habitats with well-drained automorphic soils, moderately moist in summer) (definitions by: Ermakov, 2012). Acidic psammozems and podburs composed of sandy sediments are developed in such habitats. In the first half of the 20th century, such vegetation was described in the East European tundras in ecological-physiognomic classification traditions by Soviet geobotanists V. N. Andreyev, I. D. Bogdanovskaya-Giyenef, A. A. Dedov and Z. N. Smirnova. They attributed it to lichen, dwarf-shrub-lichen and dwarf-shrub vegetation types on sandy substrates. Based upon the analysis of 196 relevés (142 of them are in this paper) from 34 sites on the Kolguyev Isl., Malozemelskaya and Bolshezemelskaya tundras, Pechora River Delta and Northern Timan Ridge (Fig. 1), we described 5 associations (including 3 subassociations and 10 variants) by Braun-Blanquet classification approach; 4 syntaxa are left in the rank of community type. Two associations of Loiseleurio-Arctostaphylion alliance, first described in the mountain regions of Fennoscandia, are also basic in the East European tundras. The area of ass. Empetro–Betuletum nanae Nordhagen 1943 occupying the lower sub-belt of the mountain-tundra belt of Fennoscandia, is also common in the plain areas in more moderate conditions in the south tundra and forest-tundra (Table 4, rel. 1–13; Table 6, syntaxon 10; Fig. 9а, б, 10). Ass. Loiseleurio-Diapensietum (Fries 1913) Nordhagen 1943, described in the upper sub-belt of the mountain-tundra belt, is represented by subass. salicetosum nummulariae Koroleva 2006 in the plain areas with its distribution area from typical tundra on Kolguyev Isl. to the northern forest-tundra in the mainland. Three variants of subassociation are identified on the latitudinal gradient: inops — on the Kolguyev Isl., Diapensia lapponica — in the continental typical tundra and Loiseleuria procumbens — in the south tundra and forest-tundra (Table 2, rel. 1–35; Table 6, syntaxa 6–9; Fig. 4а–в, 5, 6). Subass. Loiseleurio-Diapensietumsalicetosum nummulariae was first described in the tundra zone of the Kola Peninsula for petrophytic communities with a polygonal structure in oligochion and achion habitats (Koroleva, 2006). We attributed dwarf-shrub-lichen communities dominated by chionophobic lichens (Flavocetraria nivalis, Alectoria nigricans, A. ochroleuca, Bryocaulon divergens) with irregularly-mosaic horizontal structure on sandy substrates to this subassociation due to the high similarity of the species composition (Table 2). Ass. Empetro hermaphroditi–Salicetum nummulariae Bogdanovskaya-Giyenef ex Lavrinenko et Lavrinenko ass. nov. hoc loco (Table 1, rel. 1–18; nomenclatural type (neotypus hoc loco) — rel. 6 (author’ number — К157, Kolguyev Isl., Khayropskoye Lake environs, 10.09.2007, authors — O. V. Lavrinenko, I. A. Lavrinenko); Table 6, syntaxa 1–4; Fig. 2а–в, 3) with variants Tanacetum bipinnatum, Racomitrium canescens and Betula nana unites dwarf-shrub communities corresponding to different stages of the succession of the overgrown of open sands. They are common in the typical tundra subzone on Kolguyev Isl. and in the north-east part of Malozemelskaya tundra in sites with large sandy outcrops. The area of ass. Cladonietum rangiferino–arbusculae ass. nov. hoc loco (Table 4, rel. 14–20; nomenclatural type (holotypus hoc loco) — rel. 19 (author’ number — Т29,, Malozemelskaya Tundra, Kolokolkova Bay, Tobseda village (uninhabited) vicinity, 14.07.2002, author — O. V. Lavrinenko); Table 6, syntaxon 11; Fig. 12а, б) is so far limited by the coastal part of the Malozemelskaya tundra (it will probably be expanded). Communities transformed by reindeer grazing are left in the rank of community type — Dicranum elongatum–Salix nummularia com. type (Table 3, rel. 1–28; Table 6, syntaxon 5; Fig. 7а, б, 8) as well as draft-shrub-lichen with Cladonia stellaris — Cladonia stellaris com. type (Table 4, rel. 21–22; Fig. 11а). Regional characteristic species are established for Loiseleurio-Arctostaphylion alliance — psammophytic moss Polytrichum piliferum and lichens Cetraria aculeata (incl. C. muricata), C. nigricans, Cladonia pyxidata, C. cervicornis subsp. verticillata. The basic association— Phyllodoco–Vaccinietum myrtilli Nordhagen 1943 in Phyllodoco–Vaccinion myrtilli alliance in the East European tundras is represented by two subassociations: P.–V. m. salicetosum herbaceae subass. nov. hoc loco(Table 5, rel. 1–14; nomenclatural type (holotypus hoc loco) — rel. 4 (author’ number — 88_12, Kolguyev Isl., Bugryanka River in the midstream, 21.08.2012, authors — O. V. Lavrinenko, I. A. Lavrinenko); Table 6, syntaxon 12; Fig. 13а and б, 14, 15) — on Kolguyev Isl. and P.–V. m. veratretosum lobeliani subass. nov. hoc. loco (Table 5, rel. 15–33; nomenclatural type (holotypus hoc loco) — rel. 24 (author’ number — БН31_14, Bolshezemelskaya Tundra, Bolvanskiy Nos Cape, 27.07.2014, authors — O. V. Lavrinenko, I. A. Lavrinenko); Table 6, syntaxon 13; Fig. 16а–в, 17 ) — in the mainland areas in typical, south tundra subzones and northern forest-tundra. Floristic differences between them are caused by differences both in area distribution of some species, and habitats. There are some taxa of Salicetea herbaceae Br.-Bl. 1948 class on Kolguyev Isl, which indicates more nival conditions. The subass. P.–V. m. salicetosum herbaceae seems to be widespread on the Kola Peninsula. There are 2 variants in each subassociation: Vaccinium myrtillus and Chamaepericlymenum suecicum. Vaccinium myrtillus communities with Cladonia stellaris and Vacciniumuliginosum subsp. microphyllum are left in the rank of community type — Cladonia stellaris–Vaccinium myrtillus com. type (Table 5, rel. 34, 35; Fig. 18) and Vaccinium microphyllumcom. type (Table 5, rel. 36–39; Table 6, syntaxon 15; Fig. 19) due to the small number of relevés. The results of geographical analysis of vascular plant coenoflora of Loiseleurio-Arctostaphylion alliance syntaxa are as follows: dominating arctic species — 45 %, hypoarctic — 32 % and boreal — 23 %; there are no boreal species among the high-constant ones, the number arctic and hypoarctic species is approximately equal. The analogous data for of Phyllodoco–Vaccinion myrtilli alliance syntaxa: arctic, hypoarctic and boreal fractions — 33 % each; hypoarctic species dominates among the high-constant ones, boreal (including arcto-boreal) — 2times less and only 2 — arctic-alpine species.

Сосновые леса с моховым ярусом, в котором доминируют виды Sphagnum, широко распространены по всей лесной зоне Восточной Европы. Они встречаются в неглубоких депрессиях рельефа и по окраинам верховых болот. В этих условиях среды сосняки представляют собой первичные леса, так как сосна не имеет здесь других древесных видов, способных конкурировать с ней. Сфагновые сосняки были поделены на три ассоциации, различающиеся условиями местообитания и группами дифференциальных видов. Vaccinio uliginosi-Pinetum занимает олиготрофные местообитания; ее характерные виды - Vaccinium uliginosum и Ledum palustre, имеющие там экологический и фитоценотический оптимум. Асс. Molinio-Pinetum характеризуется доминированием Molinia caerulea и Vaccinium myrtillus и высоким постоянством Polytrichum commune. Вариант Equisetum sylvaticum представляет собой переход к мезотрофным заболоченным соснякам асс. Carici lasiocarpae-Pinetum. Доминанты травяного яруса этой ассоциации - Carex lasiocarpa и Menyanthes trifoliata.

Abstract The in vitro methods of Biotechnology have been used for analyzing of germination stages and grow conditions of Vaccinium L. subgenera spread in Armenia (Vaccinium myrtillus L. and Vaccinium uliginosum L.). These studies reveal that optimum conditions for in vitro germination of wild blueberry Vaccinium myrtillus and Vaccinium uliginosum seeds were: cold stratification 4-5 0C for 8 weeks, wherein the percentage of germinated seeds was 74.2 – 88.3%. The regenerative potential of shoot and root formation of the analyzed subgenera’s depends on the grow regulators composition of the medium. This Vaccinium L. in vitro study can be used for future using in breeding systems and production.

Full textAbstract:
Many recent researches in vitro and in vivo proved the large therapeutic potency of non-toxic anthocyans in anti-inflammatory, anti-infective, anti-oxidative actions. Anthocyanin is a natural phenolic colorant approved in many countries. A reason why the world market of natural food colorants is reduced is because fruit and berry raw materials are expensive. Yet the fruit and berry raw materials are extracted with significant losses and by-products. This constitutes around 23-45% of the whole amount of berries processes in the Russian Federation. Thus, a priority direction of the food industry is a development of technologies allowing to use precious berry pomace with high bioactive compounds, i.e. anthocyans, organic acids, pectin. The aim of the research is to extract food colorant from the pomace of Vaccínium myrtíllus and Vaccínium vítis-idaéa to identify individual anthocyanin pigments. The food safety and composition of the pomace of Vaccinium myrtillus and Vaccinium vitis-idaea as raw material for food colorant extraction were found. Individual anthocyanin pigments of anthocyanin extracts were identified through the method of high-performance liquid chromatography. Cyanidin-3-galactoside was found in the extracts of berries (85,6 %) and pomaces (81,2%) of Vaccinium vitis-idaea. Fifteen compounds were identified in the extracts of Vaccinium myrtillus. The major ones were delphinidin-3-glucoside (13,4 %), delphinidin-3-galactoside (12,4 %), and cyanidin-3-glucoside for the fresh berries. As for the pigments of its pomaces, they were delphinidin-3-glucoside (15,3 %), delphinidin-3-galactoside (14,7 %), and delphinidin-3-arabinoside (10,5 %). Hence, there are more anthocyanin pigments in the extracts of pomaces, than in those of the fresh berries with identical compounds – 24,7 % more for Vaccinium myrtillus and 11,1 % more for Vaccinium myrtillus. The possibility to extract anthocyanin pigments from by-products of the local fruit and berry raw materials – i.e. of Vaccinium myrtillus and Vaccinium vitis-idae ones – and identify them is discussed.

The paper identifies photosynthetic pigments pools balance and phenolic compounds in suffruticous species of Vaccinium myrtillus L. and Vaccinium vitis-idaea L. on the Tundrinsky bor territory (Khanty-Mansi Autonomous Okrug - Yugra) for the purpose of ecological and biochemical assessment of the valuable plant species status. The authors carry out a comparative analysis of the studied biochemical parameters (chlorophyll a , chlorophyll b , carotenoids and phenolic compounds) of two species leaves, collected from two sample plots similar in landscape and soil and hydrological conditions of the weakly disrupted territory of the Tundrinsky bor territory. The analysis of the suffruticous species leaves for chlorophyll content revealed the following distribution of chlorophyll pools: chlorophyll a - 64,96%, chlorophyll b - 35,04% for leaves of Vaccinium myrtillus and chlorophyll a - 68,28%, chlorophyll b - 31, 72% for leaves of Vaccinium vitis-idaea . The average content of carotenoids and phenolic compounds of Vaccinium myrtillus leaves was 0,62 0,11 mg/g and 14,18 1,65 mg/g, respectively, in Vaccinium vitis-idaea leaves - 0,52 0,12 mg/g and 18,79 2,25 mg/g, respectively. The correlation analysis showed the presence of a direct average strength correlation (r = 0,4) between the levels of chlorophyll and phenolic compounds in the leaves of Vaccinium vitis-idaea .

Full textAbstract:
Sun radiation consists of several spectrum regions, depending on the wavelengths, such as ultraviolet, visible and infrared portions. The ultraviolet rays (UV) are associated with both positive and negative effects on humans’ health. Ultraviolet light is used in the process of disinfection, it shows immunoregolatory activity and it stimulates vitamin D and serotonin production. It is well known that artificial sources of UVR are employed in the health field for sterilization procedures and for therapeutical purposes, such as treatment of dermatological pathologies like psoriasis, vitiligo and icterus neonatorum, as well as for aesthetic purposes (sunbed). In the last decade, besides these positive effects, UV side effects on skin have been demonstrated by different studies which correlated the intense and prolonged exposure to UV light with skin cancer development.
Based on wavelength, UV spectrum can be divided into three segments: UVA (320-400 nm), UVB (280-320 nm) and UVC (100-280 nm). Radiation in the UVC range, considered to be the most cytotoxic and harmful, is largely absorbed by the stratospheric ozone layer, so UV regions mainly involved in photocancerogenesis development are considered to be ultraviolet radiation A (UVA) and ultraviolet radiation B (UVB). The amount and the UVA/UVB ratio that reach the Earth’s surface is influenced by a lot of environmental factors as latitude, seasons, weather/atmospheric conditions and the time of day.
UVA is by far the most abundant solar UV radiation that reaches the Earth (about 90-95% of total UV radiation), penetrates the human epidermis down to the proliferative basal cells and even further to the derma and mediate biological events generating reactive oxygen species (ROS) in cells. ROS oxide other cellular constituents, particularly carbohydrates, lipids, proteins and DNA. Interactions between ROS and DNA induce formation of single strand breaks (SSBs), DNA-proteins crosslink and oxidized bases. The most abundant oxidized base is the guanine that produces the 8-oxoguanine, considered as promoter of carcinogenesis.
UVB represents only 5% of total UV radiation that reaches the Earth. Besides it acts mainly at the epidermis basal layer of the skin, it is considered extremely damaging because of its high energy. UVB photons are directly absorbed by DNA and cause the formation of cyclobutane pyrimide dimers (CPDs) and pyrimidine (6-4) pyrimidone photoproducts (6-4PPs), which in turn can lead to apoptotic events or carcinogenesis development. Also tryptophan and tyrosine are modified by UVB inducing the alteration of structure and function of proteins. Moreover, UVB is able to produce reactive oxygen species (ROS) and reactive nitric species (RNS).
Cells have developed defense mechanisms and endogenous repair systems in order to reduce genotoxic damage UV-induced: complexes of antioxidant enzymes which take advantage of the presence of a metal to inactivate reactive oxygen species, and DNA repair systems like the base excision repair system (BER), used for oxidized bases, and the nucleotide excision repair (NER), used to repair photolesions like CPD and 6-4 PP. Recently, several molecules have been studied for their ability to give a contribution to these antioxidant defenses. For these reasons, there is a considerable interest in the concept of the use of phytochemicals and micronutrients present in the diet such as carotenoids, vitamin E and C, and polyphenols. This last group of compounds are well known for their several biological properties, such as their antioxidant activity, their ability to enhance the activity of DNA repair systems and also their skills in inflammatory and apoptotic events modulations.
Several epidemiological studies have demonstrated their biological effects and their efficiency in the prevention and treatment of several chronic diseases like cardiovascular, respiratory, neurodegenerative and inflammatory diseases and cancer.
So, in view of these reasons, the aim of my study was double: first, to confirm literature data regarding the different mechanisms used by UVA and UVB rays to cause damage in various models, then to investigate whether different plant-derivatives compounds, all belonging to the pholiphenols category, were able to prevent UVA- and UVB-induced damage.
I reproduced the experiments on in vitro and ex vivo models. In vitro models consist of two human keratinocytes cell lines (HaCaT and NCTC 2544 cells), generally used for routine toxicological tests and photogenotoxic evaluations. Both cell lines are non tumorigenic, but showed a different degree of differentiation, higher in HaCaT cells compared to NCTC 2544. The ex vivo model consist of a three-dimensional model of organotypic human skin cultures useful to reproduce the physiological conditions. I tested the efficiency of three compounds: a water soluble extract of Bilberry only in the in vitro models (Vaccinium Myrtillus extract, rich in polyphenols and considered to be the plant with the highest content of anthocyanins), a Thymus Vulgaris leaf extract (Thyme specie) and the synthetic Thymol (its major component), used in comparable dosages, in both models. All experimental models were pretreated in serum free medium for 1 hour with each compound and then irradiated with UVA or UVB. Control samples were treated in the same way, but not UV exposed.
In order to confirm mechanisms of UV damage and to compare results obtained in the experimental models, I performed several tests, each with a specific endpoint. I evaluated the intracellular redox status, quantifying the ROS formed and the lipid peroxidation (malondialdeide levels, MDA), immediately after the end of UVA and UVB exposure and only in the in vitro models; after, I performed some genotoxic tests (the alkaline comet test to detect single and double strand breaks in single cells, the immunostaining of the histone H2AX phosphorilated to detect only double strand breaks and the micronucleous test to detect alterations to mitotic apparatus or to chromosomes); finally I investigated effects of rays on apoptotic events, using the Annexin V test and evaluating the alteration of mitochondrial membrane potential UV-induced. After, using this same assays, I tested the protective effect of Vaccinium Myrtillus extract, thymol and Thymus Vulgaris L. extract. Vaccinium Myrtillus’ effect was evaluated only in the in vitro models, the protection of thymol and Thymus Vulgaris L. extract in both models (in vitro and ex vivo).
Results obtained confirmed the different machanisms of action of UVA and UVB in all models. Particularly, confirming the different mechanisms of damage used by UVA and UVB rays. My results showed the more oxidant UVA effect and the more genotoxic and apoptotic UVB effect.
Three natural compounds showed their different protective effect against UVA- and UVB- induced damage, in in vitro models. Moreover, thymol and Thymus Vulgaris L. extract reduced damage UV-related both in the NCTC 2544 and HaCaT cell lines but also in the ex vivo model.
Vaccinium Myrtillus extract, thymol and Thymus Vulgaris L. extract reduced, to a different extent, UVA-caused damage, on account of their antioxidant properties. Compounds revealed their ability to reduce also UVB-induced damage. The efficiency against UVB damage was lower compared to the one against UVA rays. Probably the protection was related with the ability of pholyphenols, and because of my compounds, to repair DNA damage UVB-induced increasing the expression of genes involved in NER system (specifically involved in UVB-induced damage repair).
Vaccinium Myrtillus, thymol and Thymus Vulgaris L. extract showed also their protection in the apoptotic assays, avoiding the increase of extremely damaged cells which could lead to mutagenesis development.
Results obtained in my thesis activity should be considered as preliminary data useful to investigate, in detail, mechanisms used by the three natural compounds to prevent genotoxic damage UVA- and UVB-induced. Moreover, it should be very interesting to investigate the bioavailability and the permeability of tested compounds in order to use them as food supplements for a diet enriched in antioxidants (systemic effect) or in sunscreens (topical effect).

Mustikka (Vaccinium myrtillus L.) on Vaccinium-sukuun kuuluva kasvi, joka kasvaa Euroopan, Aasian ja Pohjois-Amerikan pohjoisosissa. Vaccinium-sukuun kuuluu mustikan lisäksi muun muassa karpalo ja kanadanmustikka. Mustikka sisältää paljon terveydelle hyödyllisiä hivenaineita, vitamiineja ja antioksidantteja, minkä vuoksi sitä voidaan pitää funktionaalisena elintarvikkeena. Iso osa mustikan terveyshyödyistä on liitetty fenoleihin kuuluviin antosyaaneihin, joilla on antioksidanttisten vaikutusten lisäksi muunlaisiakin vaikutusmekanismeja, kuten solusignalointiin, geeniekspressioon, DNA:n korjausmekanismeihin ja soluadheesioon liittyviä toimintoja. Antosyaaneilla on osoitettu olevan mm. soluja suojaavia, antimikrobisia, syöpää estäviä, hermostoa suojaavia sekä lihavuutta ehkäiseviä vaikutuksia. Tämän tutkielman tarkoituksena on koota yhteen tämänhetkistä tietämystä antosyaanin rakenteesta, toimintamekanismeista sekä terveysvaikutuksista.

La myrtille et l’airelle rouge, deux arbrisseaux de la famille des Ericacées, sont consommées comme des aliments, boissons et suppléments alimentaires pour leur valeur nutritionnelle et leur richesse en polyphénols antioxydants. Dans les plantes, la qualité et la quantité de composés phénoliques sont influencées par les parties morphologiques de la plante à utiliser. En particulier, les composés phénoliques des végétaux exercent leur activité antioxydante dans la protection des lipides alimentaires et le compartiment gastrique a été proposé comme le site majeur pour le stress oxydatif lié au régime alimentaire. L’objectif général de cette thèse était d’étudier les variations saisonnières des composés phénoliques d’extraits de feuilles, branches et fruits de la myrtille et de l’airelle rouge ainsi que l’activité antioxydante de ces extraits. Pour cette étude, des extraits aqueux et hydroéthanoliques (fruits uniquement) des échantillons collectés en mai, juillet et septembre pendant les années 2013-2014 ont été obtenus par extraction assistée par microondes.Les analyses qualitatives et quantitatives par UPLC / MS des extraits de la myrtille ont montré la présence de dérivés de l’acide caféique et de l’acide p-coumarique et des glycosides de flavonols dans les feuilles tandis que des oligomères de flavanols étaient aussi présents dans les branches, et ce dans des quantités élevées. La thioacidolyse a révélé de faibles degrés de polymérisation (2-4) et l’(-)-épicatéchine comme unité principale des flavan-3-ols. Il existe une très bonne corrélation entre la Somme des Composés phénoliques par UPLC et la Teneur en Polyphenols Totaux ou l’activité antioxydante dans le test DPPH, excepté pour les feuilles du mois de mai. Ces dernières sont relativement riches en dérives de l’acide p-coumarique. Les effets de la saison apparaissent plus marqués pour les feuilles qui présentent une plus grande activité antioxydante et teneur en polyphénols en juillet et septembre. Ces paramètres sont optimaux en juillet pour les branches de myrtille. La période de de cueillette peut être définie en fonction des structures phénoliques désirées.Dans l’airelle rouge, la présence prédominante de monomères et oligomères de flavanols et de glycosides de quercétine a été identifiée dans toutes les parties morphologiques. Les proanthocyanidines contiennent la (+)-catéchine et la (-)-épicatéchine comme unités d'extension et terminale. De plus, la teneur en polyphénols totaux (méthode de Folin, UPLC) a montré une augmentation légère mais significative de mai à septembre pour les feuilles et les branches. Cette augmentation a été confirmée pour l'activité antioxydante dans le test DPPH pour les feuilles et les branches en 2014.L’activité antioxydante des extraits de myrtille et d’airelle rouge lors de l’inhibition de l’oxydation lipidique (accumulation de diènes conjugués) a été évaluée dans des conditions in vitro simulant la digestion. Tout d'abord, l'inhibition de l’oxydation lipidique a été conduite sur des émulsions huile de tournesol-dans-eau stabilisées par la sérum albumine bovine (BSA) ou des phospholipides d’œuf (PL), qui simulent l’état physique des lipides alimentaires lors de la digestion gastrique. L’oxydation a été initiée par la metmyoglobine, une forme de fer apportée par la viande rouge. Dans les deux modèles d’émulsions, les extraits aqueux des branches et des feuilles et l’extrait hydroethanolique de fruit de myrtille sont des inhibiteurs plus efficaces de l'oxydation lipidique durant la première phase de digestion (pH 5) que durant la seconde phase (pH 3). D’autre part, un extrait de feuilles de myrtille a été testé dans un modèle complet de digestion in vitro statique (étapes orale, gastrique et intestinale). L'oxydation lipidique, rapide lors de la l’étape gastrique (systèmes BSA et PL) et puis plus lente lors de l'étape intestinale (système PL), a été totalement inhibée par l'extrait de feuilles de myrtilleBilberry and lingonberry, two shrubs of the Ericaceae family, are consumed as food, beverage and dietary supplements due to their nutritional value and richness in antioxidant polyphenols. In plants, the quality and quantity of phenolic compounds are influenced by the parts of the plant to be used. In particular, plant phenolic compounds provide antioxidant activity in the protection of dietary lipids from oxidation and the gastric compartment has been proposed as a major site for diet-related oxidative stress. The aim of this thesis is to simultaneously assess the seasonal variations of phenolic compounds in leaves, stems, and fruits of bilberry and lingonberry extracts, as well as their antioxidant activity. For this study, aqueous and hydroethanolic (only fruits) extracts of bilberry and lingonberry samples collected in May, July and September during the years 2013-2014 were obtained under microwave-assisted extraction.In bilberry extracts, qualitative and quantitative analyses by UPLC/MS showed the presence of caffeoyl derivatives, p-coumaroyl derivatives, and flavonol glycosides in leaves whereas in stems, flavanol oligomers were additionally identified in significant amounts. Thioacidolysis revealed low degrees of polymerization (2-4) and (-)-epicatechin as the main flavan-3-ol unit. The sum of the phenolic compounds by UPLC was highly correlated with the Total Polyphenol Content and the antioxidant activity in the DPPH test for all the extracts except those of May leaves. The latter were relatively richer in p-coumaric acid derivatives. Seasonal effects were more marked for leaves which exhibited higher antioxidant activities and phenolic contents in July and September when these parameters were maximum in July for bilberry stems. The harvest period can be refined based on the desired phenolic structures. For lingonberry, the predominant presence of monomers and oligomers of flavanols and quercetin glycosides was found in all the morphological parts. Proanthocyanidins contain (+)-catechin and (-)-epicatechin as both extension and terminal units. The sum of the phenolic compounds by UPLC was less correlated with the Total Polyphenol Content and the antioxidant activity in the DPPH test than in bilberry. Furthermore, the total phenolic content (Folin method, UPLC) showed a slight but significant increase from May to September for both leaves and stems. This increase was confirmed for the antioxidant activity by the DPPH test for both leaves and stems in 2014.The antioxidant activity of bilberry and lingonberry extracts against lipid oxidation (formation of lipid-derived conjugated dienes) was evaluated under in vitro simulated digestion conditions. Firstly, the inhibition of lipid oxidation was performed using sunflower oil-in-water emulsions stabilized by bovine serum albumin (BSA) or egg yolk phospholipids (PL), both emulsifiers mimicking dietary components. Oxidation was initiated by metmyoglobin, a form of dietary iron from red meat. In both emulsion models, aqueous extracts from stems and leaves and the hydroethanolic fruit extract of bilberry proved to be more efficient inhibitors of lipid oxidation in the early phase of digestion (pH 5) than during the second phase (pH 3). Secondly, a bilberry leaf extract was tested in the inhibition of lipid oxidation in a complete static in vitro digestion model (oral, gastric and intestinal phases). The fast lipid oxidation in the gastric step (BSA and PL systems) and the slower lipid oxidation in the intestinal step (PL system) were totally inhibited by the bilberry leaf extract

Abstract
Flavonoids are a class of secondary metabolites in plants that are involved in many important functions. Various flavonoid compounds have also been reported to be beneficial for human health. Bilberry (Vaccinium myrtillus L.) is the characteristic field layer species in boreal forests and the fruits of bilberry are rich in anthocyanin pigments, a subclass of flavonoids. In the present work, flavonoid biosynthesis was examined in different tissues of bilberry. The focus was on the developing fruits of wild type and natural color mutants of bilberry, and on effect of solar radiation on flavonoid biosynthesis in bilberry leaves.
For the isolation of RNA for gene expression analysis, a method was optimized for different tissues of bilberry. The cDNA fragments of five genes from the flavonoid pathway, coding phenylalanine ammonia-lyase, chalcone synthase, flavanone 3-hydroxylase, dihydroflavanol 4-reductase and anthocyanidin synthase, were isolated from bilberry using polymerase chain reaction technique, sequenced, and labelled with dioxigenin-dUTP label. These homologous, bilberry-specific probes were used for determining the expression of the flavonoid pathway genes in bilberry fruits, flowers and leaves with a modified non-radioactive method developed in the course of the study. The anthocyanins, catechins, proanthocyanidins, flavonols and hydroxycinnamic acids in fruits, leaves and different fractions of bilberry were identified and quantified with high-performance liquid chromatography combined with a diode array detector and mass spectrometer.
The results demonstrate a correlation between anthocyanin accumulation and expression of the flavonoid pathway genes during the ripening of berries. A correlation between flavonol and anthocyanin biosynthesis was detected in bilberry and also in previous literature collected from flavonol and anthocyanin analyses from other fruits. Accordingly, models for the connection between flavonol and anthocyanin synthesis in fruit species were suggested. Activation of the expression of flavonoid pathway genes and accumulation of flavonoids and hydroxycinnamic acids was detected in leaves growing under direct solar radiation, compared to the shadow leaves of the same plants. Based on the results, it is suggested that cyanidin of anthocyanins and flavonol quercetin play a predominant role in the defence against high solar radiation in Vaccinium leaves.
The results give new information about the biosynthesis of flavonoids in bilberry at the gene level, in addition to the information of the composition and content of flavonoids during fruit development and in different parts of the bilberry plant. Also, new information was obtained of the roles of flavonoids in protecting plants from excess solar radiation.

Full textAbstract:
In Scotland, bilberry is well known as a member of the dwarf shrub community on moorlands, which provide valuable habitats for wildlife. Recently it has been envisaged that bilberry populations could play an important role in improving the dwarf shrub vegetation in degraded moorland areas. This study was therefore undertaken to investigate the above-ground growth dynamics of bilberry with emphasis on responses to grazing by sheep and seedling establishment. The leaf production of bilberry was increased by higher nitrogen availability. High nitrogen supply also led to greater activation of dormant buds. Abortion of buds was less when nitrogen was continuously supplied. The reproductive capacity of bilberry was shown to be decreased by herbage removal. In contrast flowering was increased following supply of high nitrogen in glasshouse conditions. Almost all the flowers developed into fruits in the field, but a very low production of fruits was reported from bilberry plants that were grown in the glasshouse. Results of a series of laboratory experiments on seed production, germination, seed storage and evaluation of a moorland seed bank confirmed that the scanty seedling recruitment of bilberry was due to the limited production of 'germinable' seeds in berries and risks imposed by the environment after dispersal particularly when seeds are in the litter layer and/or soil. This could suggest that limited picking of bilberry fruits would not have a detrimental effect on establishment of bilberry populations in moorlands. Therefore, areas could be identified which were suitable for public access and berry exploitation in Scotland. The berry production was estimated approximately to be about 3220-9660 tones per year in this zone.
