Full textAbstract:
Butterfly pea flower have great sensory attraction, but they have not yet been used widely in Vietnam. Extracts of butterfly pea flowers can be used conveniently as a natural blue colorant for food products. In this study, the identification of anthocyanin compounds in butterfly pea flowers was performed by UPLC coupled with a UV and Mass spectrometer instrument. Positive and negative ion electrospray MS/MS chromatograms and spectra of the anthocyanin compounds were determined. By analyzing the chromatograms and spectra for each ion, five anthocyanins were identified in the butterfly pea flower extract; these were delphinidin-3-(6”‐p-coumaroyl)-rutinoside, cyanidin 3-(6”-p-coumaroyl)-rutinoside, delphinidin-3-(p-coumaroyl) glucose in both cis- and trans- isomers, cyanidin-3-(p-coumaroyl-glucoside) and delphinidin-3-pyranoside. Additionally, based on their intensity, it was determined that cyanidin-3-(p-coumaroyl-glucoside) was the most abundant anthocyanin, followed by cyanidin 3-(6”-p-coumaroyl)-rutinoside, delphinidin-3-(p-coumaroyl-glucoside), delphinidin-3-(6”-p-coumaroyl)-rutinoside and delphinidin-3-pyranoside. In this study, cyanidin derivatives were discovered in butterfly pea flower extract, where these compounds had not been detected in previous studies.

Five anthocyanins, delphinidin 3- O-rutinoside, cyanidin 3- O-rutinoside, petunidin 3- O-rutinoside, malvidin 3- O-glucoside and malvidin 3- O-rutinoside, were identified. Three anthocyanins, delphinidin 3- O-glucoside, cyanidin 3- O-glucoside and pelargonidin 3- O-rutinoside, were putatively identified based on C18 HPLC retention time, absorption spectrum, including λmax, and comparisons with those of corresponding standard anthocyanins, as the compounds responsible for the pink to purple-red pigmentation of the bracts of Curcuma alismatifolia and five related species. Cluster analysis based on four major anthocyanins formed two clusters. One consisted of only one species, C. alismatifolia, and the other consisted of five. Each cluster further formed sub-clusters depending on either species or habitats.

Full textAbstract:
AbstractThe interactions between six anthocyans (cyanidin-3-O-glucoside, delphinidin-3-O-glucoside, malvidin-3-O-glucoside, cyanidin-3-O-rutinoside, delphinidin-3-O-rutinoside, malvidin-3-O-rutinoside) and cyclodextrins were investigated by means of computational techniques. Four different structures of the aforementioned anthocyans were considered, as a result of the dependence structure – pH value (flavylium cations in acidic medium, hemiketals in neutral solutions and two tautomeric quinones in alkaline environment). The results outlined that the anthocyanidin-3-O-rutinoside are favored for the obtaining of inclusion complexes with the cyclodextrins, mostly due to the larger number of OH groups involved in the formation of hydrogen bonds. For all the four types of structures, best results have been obtained for β- and γ-cyclodextrins.

Fruit color of eggplants is one of the most important traits. In the fruit peel several anthocyanins were identified. It was shown that in fruits of Japanese accessions the basic an anthocyanin was delphinidin-3-(p-coumaroyl rutinoside)-5-glucoside (nasunin), while other accessions contained tulipanin (delphinidin-3-O-rutinoside). The breeding lines for hydroponic small-size cultivation that was selected by researchers from VNISSOK contained 0,021-0,2l7 grams of anthocyanin per kilogram.

Full textAbstract:
Cyanidin-3-glycosides (arabinoside, rutinoside, galactoside and glucoside) and delphinidin- 3-rutinoside were examined for their ability to inhibit lipid peroxidation induced either by Fe(II) ions, UV irradiation or 2,2′-azobis(2-amidinopropane) dihydrochloride (AAPH) peroxyl radicals in a liposomal membrane system. The antioxidant abilities of anthocyanins were compared with a water-soluble tocopherol derivative, trolox. The antioxidant efficacies of these compounds were evaluated by their ability to inhibit the fluorescence intensity decay of the extrinsic probe 3-[p-(6-phenyl)-1,3,5,-hexatrienyl] phenylpropionic acid, caused by the free radicals generated during peroxidation. All the anthocyanins tested (at concentrations of 15-20 μm) exhibited higher antioxidant activities against Fe(II)-induced peroxidation than UV- and AAPH-induced peroxidation, suggesting that metal chelation may play an important role in determining the antioxidant potency of these compounds. It was also found that delphinidin-3-rutinoside had a higher antioxidant activity against Fe(II)-induced liposome oxidation than cyanidin-3-rutinoside, which indicates an important role of the OH group in the B ring of delphinidin-3-rutinoside in its antioxidant action. The antioxidant activity of all the anthocyanins studied was higher than that of trolox in the case of Fe(II)-induced liposome oxidation and was comparable with the action of trolox in the case of UV- and AAPHinduced liposome membrane oxidation.

Full textAbstract:
Black nightshade (Solanum nigrum) belongs to the Solanaceae family and is used as a medicinal herb with health benefits. It has been reported that the black nightshade plant contains various phytochemicals that are associated with antitumor activities. Here we employed a genetic approach to study the effects of overexpression of Arabidopsis thaliana production of anthocyanin pigment 1 (AtPAP1) in black nightshade. Ectopic expression of AtPAP1 resulted in enhanced accumulation of anthocyanin pigments in vegetative and reproductive tissues of the transgenic plants. Analysis of anthocyanin revealed that delphinidin 3-O-rutinoside-5-O-glucoside, delphinidin 3,5-O-diglucoside, delphinidin 3-O-rutinoside, petunidin 3-O-rutinoside (cis-p-coumaroyl)-5-O-glucoside, petunidin 3-(feruloyl)-rutinoside-5-glucoside, and malvidin 3-(feruloyl)-rutinoside-5-glucoside are highly induced in the leaves of AtPAP1 overexpression lines. Furthermore, ectopic expression of AtPAP1 evoked expression of early and late biosynthetic genes of the general phenylpropanoid and flavonoid pathways that include phenylalanine ammonia-lyase (PAL), cinnamate-4-hydroxylase (C4H), 4-coumarate CoA ligase (4CL), chalcone isomerase (CHI), and quinate hydroxycinnamoyl transferase (HCT), which suggests these genes might be transcriptional targets of AtPAP1 in black nightshade. Concomitantly, the total content of anthocyanin in the transgenic black nightshade plants was higher compared to the control plants, which supports phenotypic changes in color. Our data demonstrate that a major anthocyanin biosynthetic regulator, AtPAP1, can induce accumulation of anthocyanins in the heterologous system of black nightshade through the conserved flavonoid biosynthesis pathway in plants.

Full textAbstract:
Common cyclamen (Cyclamen pururascens Mill.) is a very interesting species not only for various breeding programs but also as an ornamental plant. The plants possess interesting floral and foliage characteristics, nice fragrances, and a very useful flavonol profile. The last is very important from the point of view of protecting against diseases and physiological disorders. Twenty-two different genotypes originating from different regions in Slovenia were analyzed in detail, based on their floral and foliage characteristics. Anthocyanin and flavonol contents were determined using high-performance liquid chromatography (HPLC)-photodiode array-mass spectrometry (MS). Color characteristics were colorimetrically evaluated separately for petals and leaves. In terms of color measurements, significant differences among the sites of origin were shown with parameters a* and L* when petals were analyzed, and with parameter a* when leaves were analyzed. The pH of petal sap stayed within the acid range, ranging from 3.96 to 4.82. Five different anthocyanins (malvidin-3,5-diglucoside, cyanidin-3-neohesperidoside, delphinidin-3-glucoside, delphinidin-3,5-diglucoside, and delphinidine-3-rutinoside) were analyzed in flowers, and this is the first report of delphinidin metabolites naturally present in common cyclamen genotypes. In relation to plant leaves, malvidin-3,5-diglucoside, malvidin-3-rutinoside, malvidin-3-glucoside, cyanidin-3-neohesperidoside, and peonidin-3-neohesperidoside were measured. Fifteen different flavonols were determined in common cyclamen flowers and 10 different flavonols in common cyclamen leaves. Various glycosides of quercetin, myricetin, and kaempferol were analyzed, as well as isorhamnetin-3-rutinoside, laricitin-3-rutinoside, and neohesperidin. The floral and foliage characteristics of the genotypes (physical and chemical) were mainly affected by the environmental conditions of the locality of origin of the genotypes (annual disposition of temperature and precipitation, structure of the soil, etc.).

Full textAbstract:
The aim of the study was to evaluate the activity of high-polyphenolic black currant (Ribes nigrumL.) and bilberry (Vaccinium myrtillusL.) juices against bacterial strainsAsaia lannensisandAsaia bogorensisisolated as spoilage of commercial soft drinks. The composition of fruit juices was evaluated using chromatographic techniques HPLC and LC-MS. The adhesion to glass, polystyrene, and polyethylene terephthalate in two different culture media was evaluated by luminometry and the plate count method. The major anthocyanins in theV. myrtilluswere petunidin-3-glucoside, malvidin-3-glucoside, cyanidin-3-glucoside, and delphinidin-3-glucoside, while inR. nigrumdelphinidin-3-rutinoside and cyanidin-3-rutinoside were detected. The LC-MS analysis showed presence of anthocyanins (delphinidin, cyanidin, petunidin, and malvidin derivatives), phenolic acids (chlorogenic and neochlorogenic acids), flavonols (quercetin-3-glucoside, quercetin-3-rutinoside), and flavanols (procyanidin B2 and procyanidin type A2). Additionally, in the bilberry juice A type procyanidin trimer was detected. The adhesion ofAsaiaspp. cells depended on the type of medium, carbon sources, and the type of abiotic surfaces. We noted that the adhesion was significantly stronger in minimal medium containing sucrose. The addition of bilberry and black currant juices notably reduced bacterial growth as well as cell adhesion to polyethylene terephthalate surfaces.

Full textAbstract:
(1) Background: The anthocyanin delphinidin exhibits anti-angiogenic properties both in in vitro and in vivo angiogenesis models. However, in vivo delphinidin is poorly absorbed, thus its modest bioavailability and stability reduce its anti-angiogenic effects. The present work takes advantage of small extracellular vesicle (sEV) properties to enhance both the stability and efficacy of delphinidin. When encapsulated in sEVs, delphinidin inhibits the different stages of angiogenesis on human aortic endothelial cells (HAoECs). (2) Methods: sEVs from immature dendritic cells were produced and loaded with delphinidin. A method based on UHPLC-HRMS was implemented to assess delphinidin metabolites within sEVs. Proliferation assay, nitric oxide (NO) production and Matrigel assay were evaluated in HAoECs. (3) Results: Delphinidine, 3-O-β-rutinoside and Peonidin-3-galactoside were found both in delphinidin and delphinidin-loaded sEVs. sEV-loaded delphinidin increased the potency of free delphinidin 2-fold for endothelial proliferation, 10-fold for endothelial NO production and 100-fold for capillary-like formation. Thus, sEV-loaded delphinidin exerts effects on the different steps of angiogenesis. (4) Conclusions: sEVs may be considered as a promising approach to deliver delphinidin to target angiogenesis-related diseases, including cancer and pathologies associated with excess vascularization.

Full textAbstract:
Eggplant (Solanum melongena L.) is a berry-producing vegetable belonging to the large Solanaceae family. Eggplant berries are rich in important secondary metabolites like phenolic compounds (chlorogenic acid in the flesh and anthocyanins in the peel) and flavonols, two classes of antioxidant molecules with suggested health-promoting effects in humans. Anthocyanins pathway is one of most investigated and well characterized pathway among the higher plants. However, the information available for eggplant anthocyanins pathway are rather limited whit the respect to other Solanaceous crop like tomato (S. lycopersicum ) and potato (S. tuberosum). As part of this Ph.D. project, focusing on the highly conserved MYB-bHLH-WD (MBW) transcriptional complex model, which is pivotal in the transcriptional regulation of many anthocyanins related genes, the eggplant MBW were identified and functional characterized. Moreover, a regulatory R3 MYB type repressor (Smel- MYBL1), never reported before, was identified and characterized as well. Fruit peel pigmentation of different varieties of eggplant can vary widely from white to green to purple and violet; in particular, the black/dark purple and dark/light violet peel pigmentations reflect the alternative presence of two different anthocyanins: delfinidine-3-rutinoside (D3R) and delphinidin-3-[p-coumaroylrutinoside]-5- glucoside (nasunin), respectively. The conversion of D3R into nasunin is still an unelucidated part of the anthocyanin pathway in eggplant. The genes responsible of this metabolic step, the SmAAT was identified and functionally characterized through complementation in genotypes carrying the recessive mutant aat allele. Moreover, another genes, Sm5GT1, putatively involved in this step were identified, but more efforts are needed to characterize it. Furthermore, the ripening process is a pivotal aspect which affects the anthocyanins content. The eggplant ripening is commonly divided into three stages: unripe (stage A), commercially ripen (stage B) and physiologically ripen (stage C). Anthocyanin pigments are accumulated to the highest levels at the unripe fruit stage and their levels dramatically decreased as ripening progresses (Mennella et al., 2012), although the total phenolic content remained quite stable (Esteban et al., 1992) leading to the hypothesis that some other still undetermined phenolics are produced during this stage instead of anthocyanins. Focusing on these evidences a list of phenols never reported before in the eggplant peel were identified by HPLC-DAD- UV-VIS analysis. The identification of those new compounds and the recent availability of eggplant genetic resources have allowed the identification of the genes putatively involved in the ripening metabolism of the eggplant berries. The characterization by RT-qPCR three genes were carried out: SmFLS and a couple of SmGT. This genes are now the best candidate for future experiments aimed at irrefutably proving this function.
