Flower colour is mainly due to the presence and type of pigments. Pollinator preferences impose selection on flower that ultimately acts Knowing how pollinators perceive flowers with different pigments becomes crucial for a comprehensive understanding plant-pollinator communication evolution. Based space models, we studied whether main groups pollinators, specifically hymenopterans, dipterans, ...
Abstract The benefits of grape consumption are widely recognized and mostly due to phenolic compounds. These beneficial effects will depend on the bioaccessibility these compounds its derivatives. This study elaborated two formulations Isabel preparation: PAX (with agave xylitol) PS sucrose); flour: FAX (from process residues) FS residues). products were analyzed regarding their nutritional ant...
This article is aimed at identifying the relationship between territories agro-ecological conditions and anthocyanins complex formation of grapes, which determines quality biological value red wines. Using HPLC, 'Cabernet Sauvignon' cultivar from 6 industrial vineyards, located in three natural regions Crimea, was studied. The agro-climatic resources vineyards were assessed using methods geoinf...
The spectral reflectance technique for the quantification of functional components was applied in different studies crops, but related research on kale leaves is limited. This study conducted to estimate glucosinolate and anthocyanin cultivated a plant factory based diffuse spectroscopy through regression methods. Kale grown under treatments. After specific periods transplantation, leaf samples...
The pyridinium bisretinoid A2E, an autofluorescent pigment that accumulates in retinal pigment epithelial cells with age and in some retinal disorders, can mediate a detergent-like perturbation of cell membranes and light-induced damage to the cell. The photodynamic events initiated by the sensitization of A2E include the generation of singlet oxygen and the oxidation of A2E at carbon-carbon do...
Petal spots are widespread in angiosperms and are often implicated in pollinator attraction. Clarkia gracilis petals each have a single red-purple spot that contrasts against a pink background. The position and presence of spots in C. gracilis are determined by the epistatic interaction of alleles at two as yet unidentified loci. We used HPLC to identify the different pigments produced in the p...
Analysis of Concord grape juice by HPLC with ESI-MS(n), PDA, and fluorescence detection resulted in the identification and quantification of 60 flavonoids and related phenolic compounds, which were present at an overall concentration of 1508 ± 31 μmol/L. A total of 25 anthocyanins were detected, which were mono- and di-O-glucosides, O-acetylglucosides, O-p-coumaroyl-O-diglucosides, and O-p-coum...
Blueberry consumption is associated with health benefits contributing to a reduced risk for cardiovascular disease, diabetes and cancer. The aim of this study was to determine the anthocyanin profile of blueberry extracts and to evaluate their effects on B16-F10 metastatic melanoma murine cells. Seven blueberry cultivars cultivated in Romania were used. The blueberry extracts were purified over...
Anthocyanidins are bioactive flavonoids with potential health-promoting effects. These may vary among single anthocyanidins considering differences in their bioavailability and some of the mechanisms involved. The aim of the present study was to estimate the dietary intake of anthocyanidins, their food sources and the lifestyle factors (sex, age, BMI, smoking status, educational level and physi...
The effect of cultivation practices on fruit quality and antioxidant capacity in highbush blueberries var. Bluecrop (Vaccinium corymbosum L.) was evaluated from random samples of commercial late harvest fields in New Jersey. Results from this study showed that blueberry fruit grown from organic culture yielded significantly higher sugars (fructose and glucose), malic acid, total phenolics, tota...
