Annotation:
Mount Fansipan, situated in the Hoang Lien Son Range, supports a rich subtropical and temperate flora of over 1700 species, including 25% of Vietnam’s endemic plant taxa (Nguyen & Harder 1996, Sterling et al. 2006). At elevations above 2000 m, Mount Fansipan contains numerous temperate genera including Acer Linnaeus (19 spp., Sapindaceae Jussieu), Alnus Miller (A. nepalensis, Betulaceae Gray), Betula Linnaeus (B. alnoides Buchanan-Hamilton, Betulaceae), Carex Linnaeus (36 spp., Cyperaceae Jussieu), Clematis Linnaeus (9 spp., Ranunculaceae Jussieu), Lithocarpus Blume (13 spp., Fagaceae Dumortier), Quercus Linnaeus (9 spp., Fagaceae), Rhododendron Linnaeus (40 spp., Ericaceae Jussieu), Rubus Linnaeus (36 spp., Rosaceae Jussieu), Tsuga Carrière (T. dumosa Eichler, Pinaceae Sprengel ex F. Rudolphi), Ulmus Linnaeus (U. lancifolia Roxburgh, Ulmaceae Mirbel), Vaccinium Linnaeus (12 spp., Ericaceae), and Viola Linnaeus (12 spp., Violaceae Batsch) (Vietnam Plant Data Center 2015, Nguyen & Harder 1996) with many of these genera being both species-rich and locally common (Nguyen & Harder 1996, pers. obs.). In April 2012, a collection of a specimen, representing the temperate genus Luzula de Candolle (1805: 158), was made while conducting botanical studies on the Carex flora of Mount Fansipan, Lao Cai Province, Vietnam, which is about 30 km south of the border with Yunnan Province, China. While the specimen was immediately recognized as a Luzula, a new genus to the flora of Vietnam (Vietnam Plant Data Center 2015), it was not until our collection was identified using the keys in Wu & Clements (2000) and Kirschner (2002) that it was determined to be Luzula effusa Buchenau (1879: 88) (Figs. 1, 2). A Basic Alignment Search Tool (BLAST) search of an internal transcribed spacer region (ITS1+5.8S+ITS2) sequence obtained from our specimen (KM612280) showed a 100% match with an existing sequence for L. effusa var. chinensis (Brown 1903: 161) Wu (1992: 92) (AY727778.1, see Drábková & Vlcek 2010) in GenBank (National Center for Biotechnology Information 2014), supporting our identification based on morphology (Table 1). Eighteen other Luzula accessions, representing species placed in two different subgenera and four different sections, were found to have 100% coverage and 99% identity with the sequence from our specimen (National Center for Biotechnology Information 2014) (Table 1). In all cases, these sequences came from taxa that occur in regions that are more geographically disparate from Vietnam than the previously known closest location for L. effusa (see below). These taxa are also morphologically dissimilar to our specimen (see text below and Table 1).

U ovoj doktorskoj disertaciji prikazani su rezultati istraživanja 15 vrsta  biljaka  koje  pripadaju  rodovima Rumex,  Polygonum, Bistorta,  Persicaria i  Fagopyrum,  podfamilije  Polygonoideae, familije  Polygonaceae,  sakupljenih  na  teritoriji  centralnog  i zapadnog  Balkana u periodu od 2009-2011. godine. Sprovedena istraživanja  su  se  odvijala  u  dva  pravca:  fitohemijska  i biohemijsko-biološka  ispitivanja.  Predmet  analiza  bili  su ekstrakti  herbi  i  rizoma  ispitivanih  biljaka.  Fitohemijska ispitivanja  obuhvatila  su,  pored  spektrofotometrijskog određivanja  ukupnih  fenola,  ukupnih  flavonoida  i  ukupnih antrahinonskih jedinjenja, i određivanje sadržaja 51 komponente iz standardne smeše različitih klasa fenolnih jedinjenja LC-MSMS  metodom,  odnosno  hromatografsko  profilisanje  ekstrakata LC-DAD-MS  metodom.  Odabirom  nekoliko  različitih  model sistema  za  merenje  antioksidantne  aktivnosti  (neutralizacija DPPH  radikala,  redoks  kapacitet  -  FRAP  test,  skevindžer aktivnost  prema  superoksidanjon  radikalu,  NO  radikalu  i  OH radikalu,  kao  i  inhibicija  lipidne  peroksidacije)  procenjen  je antioksidantni  potencijal  ekstrakata,  dok  je  za  procenu  njihove antiinflamatorne  aktivnosti  korišćen  potencijal  inhibicije biosinteze medijatora inflamacije u humanim trombocitima (kao model  sistemu).  Mikrobiološka  ispitivanja  su  obuhvatila određivanje  potencijala  ovih  vrsta  u  inhibiciji  rasta  serije  gram pozitivnih i gram negativnih sojeva batkerija. Konačno, urađena je  analiza  korelacije  hemijskog  sastava,  biološke  aktivnosti  i pripadnosti taksonomskim grupama.
Phytochemical  and  biochemical  analysis  of  herbal  and  root ethanol  extracts  of  15  species  belonging  to  different  genera (Rumex,  Polygonum,  Bistorta,  Persicaria and  Fagopyrum)  of subfamily  Polygonoideae,  was  examined.  Phytochemical characterization  included  spectrophotometric  determination  of total  phenolic,  total  flavonoids  and  total  anthraquinone  contents, quantification  of  51  secondary  metabolites  by  LC/MS/MS analysis  and  chromatographic  fingerprinting by  LC/DAD/MS technique,  of  prepared  extracts.  The  antioxidant  activity  was evaluated  by  measuring  ferric  reducing  ability  (FRAP)  of  the extracts and their radical scavenging capacity towards DPPH, OH, NO and O2– radicals, and inhibition of lipid peroxidation).

Annotation:
Štavelj (Rumex crispus, Polygonaceae) je višegodišnja zeljasta biljka, koja predstavlja bogat izvor fenolnih komponenti. Iako se smatra invazivnim korovom, mlado lišće štavelja je jestivo i često se koristi kao salata. Dalje, upotreba plodova štavelja opisana je u srpskoj i turskoj narodnoj medicini u lečenju gastrointestinalnih tegoba. Cilj ovog rada bio je procena in vitro i in vivo antioksidantne/prooksidantne i citotoksične aktivnosti, i određivanje eventualnog in vitro antiinflamatornog efekta vodenog ekstrakta ploda Rumex crispus. Ukupan sadržaj flavonoida određen je spektrofotometrijskom metodom. Kvalifikacija i kvantifikacija flavonoida potvrđena je visokoefikasnom tečnom hromatografijom (HPLC). Antioksidantna aktivnost vodenog ekstrakta ploda štavelja procenjena je na osnovu in vitro testova: Ferric-reducing antioxidant power (FRAP), sposobnosti ekstrakta da neutrališe slobodne radikale NO•, OH• i DPPH• i uticaja na lipidnu peroksidaciju u lipozomima. Citotoksičnost ispitivanog ekstrakta je određena in vitro na tumorskim ćelijskim linijama: humani karcinom cerviksa (HeLa), adenokarcinom (HT-29) i adenokarcinom dojke (MCF7). Takođe, moguća in vivo hepatoprotektivna i antioksidantna svojstva ekstrakta određena su kod oksidativnog stresa izazvanog CCl4 kod eksperimentalnih životinja. Pored toga, proverena je hipoteza u kojoj testiran ekstrakt pokazuje in vivo antiproliferativnu aktivnost kod Ehrlich-ovih (EAC) i Hepatoma AS30D ćelija, merenjem zapremine ascitesa, procenta vijabilnih ćelija i nivoa nekoliko antioksidantnih enzima. Optimizovan in vitro test za određivanje potencijala inhibicije ciklooksigenaze-1 (COX-1) i 12-lipooksigenaze (12-LOX) preduzet je u svrhu procene antiinflamatornog efekta vodenog ekstrakta ploda R. crispus. HPLC analiza otkrila je da je mikvelianin najdominantniji flavonoidni konstituent ekstrakta. Testirani ekstrakt pokazao je potencijalnu antioksidantnu aktivnost rezultujući velikom moći u neutralizaciji slobodnih radikala, i sposobnošću da smanji lipidnu peroksidaciju u lipozomima. Rezultati su ukazali na tkivno-selektivnu citotoksičnost ekstrakta ploda R. crispus in vitro. Najizraženija antitumorska aktivnost primećena je prema HeLa i MCF7 ćelijskim linijama. Podaci sugerišu da bi se ispitivani ekstrakt mogao smatrati potencijalnim in vivo hepatoprotektivnim i antioksidantnim agensom, sprečavajući oksidativna oštećenja jetre. S druge strane, pomenuti ekstrakt može pokazati in vivo prooksidantna svojstva, uzrokujući oksidativni stres u maligno transformisanim EAC i AS30D ćelijama i smanjujući zapreminu ascitesa i udeo vijabilnih ćelija, u poređenju sa kontrolnom grupom. Promene u aktivnosti antioksidantnih enzima su verovatno posledica indukovanog oksidativnog stresa u EAC i AS30D ćelijama, naročito kod pretretiranih životinja. Vodeni ekstrakt ploda štavelja pokazao je COX-1, kao i 12-LOX inhibitornu aktivnost, navodeći da bi ispitivani ekstrakt mogao biti antiinflamatorni agens. Vodeni ekstrakt ploda R. crispus ima potencijalnu antioksidantnu, citotoksičnu i antiinflamatornu aktivnost. Ispoljavanje prooksidantnih svojstava predstavlja mogući mehanizam antiproliferativnog efekta ekstrakta.
Curly dock (Rumex crispus, Polygonaceae) is a wild perennial herbaceous plant, which products are described as a rich source of phenolic compounds. Apart from being considered a seriously invasive weed, young leaves of curly dock are edible and often used as salad. Furthermore, the use of its fruits has been described in Serbian and Turkish traditional medicine against stomach complaints. The objectives of this study were to evaluate in vitro and in vivo antioxidant/prooxidant and cytotoxic activities, and to determine an eventual in vitro anti-inflammatory effect of the aqueous extract of Rumex crispus fruits. Total flavonoid content was determined by spectrophotometric method. Qualification and quantification of flavonoids were confirmed using High performance liquid chromatography (HPLC). The aqueous extract of curly dock fruits was evaluated for its antioxidant activity by in vitro assays for Ferric-reducing antioxidant power (FRAP), NO•, OH• and DPPH•-free radical scavenging activities and the influence on lipid peroxidation in liposomes. The cytotoxicity of tested extract was examined in vitro in human cervix carcinoma (HeLa), colon adenocarcinoma (HT-29) and breast adenocarcinoma (MCF7). Also, the potential in vivo hepatoprotective and antioxidant properties of investigated extract were determined on CCl4-induced oxidative stress in experimental animals. Furthermore, the hypothesis that the examined extract might show in vivo antiproliferative activity in Ehrlich carcinoma (EAC) and Hepatoma AS30D cells was tested by measuring volume of ascites, percentage of viable cells and level of several antioxidant enzymes. The optimized in vitro test for determination of cyclooxygenase-1 (COX-1) and 12-lipoxygenase (12-LOX) inhibition potency was undertaken in order to estimate an anti-inflammatory effect of aqueous extract of R. crispus fruits. HPLC analysis revealed miquelianin as the most abundant flavonoid constituent of the extract. The tested extract might have an antioxidant activity resulting in scavenging of free radicals and ability to decrease lipid peroxidation in liposomes. The results could indicate tissue-selective cytotoxicity of R. crispus fruit extract in vitro. The most prominent antitumor activity was observed towards HeLa and MCF7 cell lines. The data suggested that investigated extract may be considered as potential in vivo hepatoprotective and antioxidant agent due to prevention of the liver injuries induced by oxidative damage. On the other hand, mentioned extract could exhibit in vivo prooxidant property, causing the oxidative stress in malignant transformed EAC and AS30D cells and reducing volume of ascites and percentage of viable cells, in comparison with control group. Changes in activities of antioxidant enzymes might be the results of induced oxidative stress in EAC and AS30D cells, especially in the pretreated animals. The aqueous extract of curly dock fruits showed COX-1, as well as 12-LOX inhibitory activity, suggesting that tested extract might be an anti-inflammatory agent. It could be concluded that aqueous fruit extract of R. crispus might have antioxidant, cytotoxic and anti-inflammatory activities. The prooxidant properties of examined extract could be the mechanism of potential antiproliferative effect of extract.

Resumo: A família Rubiaceae é composta por plantas de hábito variado e representa a quarta maior família de Angiospermas, com cerca de 10.700 espécies; é cosmopolita e apresenta grande riqueza de espécies no Cerrado brasileiro. Objetivando ampliar o conhecimento cromossômico da família, foi realizado um estudo com 14 espécies pertencentes a duas das subfamílias do grupo, coletadas em áreas de Cerrado no estado de São Paulo (Assis, Campinas, Itirapina,M()gi-GuélÇu e M()gi-Mirim) e Mélto Gro_so_() . Sul (Três Lagoas). Na subfamília Ixoroideae, cinco espécies apresentaram número cromossômico 2n = 22 (Alíbertia concolor, A.edulis, A. sessilis, Genipa americana e Tocoyena formosa), e uma apresentou poliploidia, com 2n = 66 (Amaioua intennedia). No entanto, todos são números múltiplos do número básico mais comum da família, x = 11. Por outro lado, as espécies pertencentes a subfamília Rubioideae exibiram variações entre as tribos e gêneros. observando-se os .números 2n = 20 (Coccocypselum lanceo/atum), 2n = 22 (Psychotria hoffmannseggiana) ou n = 11 (Coussarea hydrangeífolía e Palicourea rigida), 2n = 28 (Borreria latifolia, Borreria verticillata eRichardia brasiliensis) e 2n = 32 (Psychotria deflexa). Foram elaborados os cariótipos de 12 espécies, sendo todos inéditos (à exceção de Genipa americana). assim como a maioria dos números cromossômicos. O tamanho dos cromossomos variou entre 7 ,33 _m e 1 ,26 _m. Os cromossomos são em sua maioria metacêntricos e os cariótipos são simétricos (TF% variando de 47,45 a 38,01). Sugere-se que a maior constância de números cromossômicos em relação ao número básico x = 11 seja um apoio à proposta de que a tribo Ixoroideae seja mais basal na família, ao contrário do que ocorre em Rubioideae, apontada como sendo mais derivada com base em caracteres morfológicos

Polygonum compreende aproximadamente 30 espécies distribuídas principalmente em regiões temperadas do hemisfério norte. Para o Brasil são aceitas 16 espécies, tipicamente de ambientes úmidos, sendo 10 registradas para o Rio Grande do Sul. A análise de caracteres morfológicos e a delimitação de espécies de Polygonum em ambientes úmidos do extremo sul do Brasil foi o objetivo deste estudo. O trabalho foi realizado com base em coletas, observações a campo e análises morfológicas pelo microscópio estereoscópico e MEV – microscópio eletrônico de varredura, em exemplares coletados e de Herbários. Foram registradas nove espécies: P. acuminatum Kunth, P. aviculare L., P. capitatum Buch.-Ham. ex D. Don, P. ferrugineum Wedd., P. glabrum Willd., P. hydropiperoides Michx., P. meisnerianum Cham. & Schltdl., P. persicaria L. e P. punctatum Elliot.. A separação das espécies se deve principalmente por características das inflorescências, como a forma, tamanho, localização e densidade de flores, forma dos frutos e presença/ausência de cílios nas ócreas. Polygonum hydropiperoides e P. punctatum são muito confundidas, distinguindo-se pelas inflorescências lineares interrompidas na base e presença de glândulas principalmente nas tépalas da última. Polygonum punctatum foi a espécie mais comum na área estudada. Por outro lado, P. persicaria mostrou ser rara no local por ter poucos indivíduos coletados, e especialmente P. aviculare, P. capitatum e P. glabrum, por só serem encontrados exemplares em herbário. O número de espécies registradas para a área estudada retrata a importância deste gênero para o extremo sul do Brasil, cuja área detém a quase totalidade de espécies registradas para o Estado.
Polygonum comprises about 30 species distributed mainly in high temperate regions of the northern hemisphere. For Brazil, 16 species are accepted, typically wet environments, being 10 recorded for the Rio Grande do Sul. The analysis of morphological characters and the delimitation of species of Polygonum in moist environments from southern Brazil was the objective of this study. The study was based on collections, field observations and morphological analyzes by stereoscopic microscope and SEM - scanning electron microscope, on specimens and in herbaria. Nine species were recorded: P. acuminatum Kunth, P. aviculare L., P. capitatum Buch.-Ham. ex D. Don, P. ferrugineum Wedd., P. glabrum Willd., P. hydropiperoides Michx., P. meisnerianum Cham. & Schltdl., P. persicaria L. and P. punctatum Elliot. Separation of species is mainly by characteristics of inflorescences, such as shape, size, location and density of flowers, fruit shape and presence/absence of cilia in ochreas. Polygonum hydropiperoides and P. punctatum are very confused, but are distinguished by linear inflorescences interrupted at the base and presence of glands especially in the last tepals. Polygonum punctatum was the most common species in the study area. On the other hand, P. persicaria shown to be rare in place by having a few individuals collected, especially P. aviculare, P. capitatum and P. glabrum, by being found only in herbarium specimens. The number of species recorded for the study area portrays the importance of this genre to the extreme southern Brazil, whose area holds almost all the species recorded for the State.

The native tree Triplaris americana L. (Polygonaceae) is dioecious and occurs mainly along rivers and riparian areas of semi-deciduous broadleaf forest in the states of Mato Grosso, Mato Grosso do Sul and west of the state of São Paulo. During flowering, which occurs between the months of August to October, the production of pollen in male individuals may serve as a reservoir for mites mainly predators, keeping them and promoting increase of their population. In general, mites of this family are a group of efficient predators of phytophagous mites, as several studies indicate that these mites are important biological control agents and essential programs for integrated pest management. This study aims to analyze the diversity and seasonal occurrence of mites in male and female individuals of T. americana. Samples were collected from five male and five females trees, present in the urban area of São José do Rio Preto, São Paulo. To compare the abundance of mites between male and female subjects of T. americana, was applied to analysis of variance (ANOVA) with repeated measures. To verify the relationship between the abundance and species richness with rainfall, was used linear regression. The maximum theoretical diversity was also determined. In male specimens were collected from 29,968 mites belonging to 29 species, and in female, 22,767 mites of 30 species. The diversity of species of mites in samples of both sexes of T. americana study was less than 50% of the maximum theoretical diversity. As phytophagous species more abundant in the sexes were Lorryia formosa Cooreman, Allonychus brevipenis Feres, Aculus sp. and Lorryia sp.1. The highest abundance of predators occurred during flowering, Euseius citrifolius Denmark & Muma and Metapronematus sp.1., predatory mites, were the most common and of constant occurrence. Euseius citrifolius presented its highest abundance... (Complete abstract click electronic access below)

Morphological variations in Taiwan Polygonum L. s. l. were analyzed. All characters selected from leaves, trichomes, inflorescences, flowers, and pollens are useful in differentiating species, and are also valuable in classifying genera and sections. There are 37 species and 2 varieties of Polygonum L. s. l. found in Taiwan, and 5 genera are recognized: Polygonum L. s. s. , Fallopia Adans, Keonigia L. , Fagopyrum Mill. , and Persicaria (L.) Mill. . Fallopia Adans is divided in two sections, sect. Pleuropterus (Turcz.) Haraldson and sect. Reynoutria (Houtt.) Ronse Deer. . There are four sections in Persicaria (L.) Mill. : sect. Echinocaulon (Meisn.) Gross, sect. Tovara (Adans.) Gross, sect. Cephalophilon (Meisn.) Gross and sect. Persicaria (Mill.) Gross. New combinations include Fallopia multiflora Thunb. var. hypoleuca (Ohwi) Kuo, Persicaria micrantha (Meisn.) Kuo, Persicaria chinensis var. auriculatis (Suzuki) Kuo, and Persicaria pilushanensis (Liu et Ou) Kuo.

Die Ranunculaceae sind eine der sieben Familien der Ordnung Ranunculales. Mit ca. 2500 Arten in 55 Gattungen sind sie die größte Familie der Ordnung. Da Gattungsgrenzen teilweise unklar sind, kann keine endgültige Gattungszahl angegeben werden. Die vorliegende Bearbeitung behandelt vor allem die Morphologie und Ökologie der Vertreter der Familie und enthält auch einen Schlüssel zum Bestimmen der im Gebiet verbreiteten Gattungen der Familie Ranunculaceae.

We have investigated the phytostimulating properties of Rheum officinale Baill. (Polygonaceae) root and leaves water-ethanol extracts and Azadirachta indica A. Juss. (Meleaceae) seed oil extract, which contain a wide range of bioactive substances. Experiments to determine the effect of treatment with extracts of Cucumis sativus seedlings were carried out in laboratory conditions. The composition V6 (1%R + 0,5%L) showed the maximum phytostimulating effect, which increased the plant height by 34,5%, and the number of flowers by 89,6%.
