Detection of Anthocyanins/Anthocyanidins in Animal Tissues

Journal of Agricultural and Food Chemistry, 2014
Dietary polyphenols may contribute to the prevention of several degenerative diseases, including cancer. Anthocyanins have been shown to possess potential anticancer activity. The aim of this study was to determine anthocyanin bioavailability in lung tissue of mice fed a blueberry diet (5% w/w) for 10 days or a bolus dose (10 mg/mouse; po) of a native ...

Antioxidant properties of anthocyanidins, anthocyanidin-3-glucosides and respective portisins

Food Chemistry, 2010
The study of the antioxidants properties of three classes of pigments, namely anthocyanidins (cyanidin-Cy, delphinidin-Dp and malvidin-Mv), anthocyanidin-3-glucosides (Cy-3-gluc, Dp-3-gluc and Mv-3-gluc), and portisins (Cy-pt, Dp-pt and Mv-pt) was carried out.

Conversion of Leucoanthocyanins into the Corresponding Anthocyanidins

Science, 1964
Purified preparations of leucoanthocyanins from several sources were heated in butanol-hydrochloric acid solutions from 50° to 90°C and the rate of production of cyanidin was measured. From the temperature dependence of this rate, the calculated energy of activation was of the order of magnitude of 20,000 calories.

Computational aspects of anthocyanidins and anthocyanins: A review

Food Chemistry, 2019
Anthocyanins and anthocyanidins are polyphenolic compounds, responsible for the red and blue colours in several fruits, flowers, and leaves. Their colorant properties, bioavailability and antioxidant activity, made anthocyanins and anthocyanidins largely adopted in food and pharmaceutical industries.

Fluorescent Products of Anthocyanidin and Anthocyanin Oxidation

Journal of Agricultural and Food Chemistry, 2020
We found that the oxidation of cyanidin with hydrogen peroxide, tert-butyl hydroperoxide, 2,2'-azobis(2-methylpropionamidine), 3-morpholinosydnonimine hydrochloride, sodium hypochlorite, Fe3+, and Fe2+ induced the appearance of a new fluorescence band, centered at 525-540 nm when excited at 470-490 nm.

Structure–activity relationships of anthocyanidin glycosylation

Molecular Diversity, 2014
This paper summarizes the main achievements about the structure-activity relationships of anthocyanidin glycosylation. Anthocyanidin glycosylation is the essential step of anthocyanin biosynthesis and also the prerequisite of the further modifications of anthocyanins, which is jointly characterized by the glycosylation site, the type and number of the ...

Inhibitory actions of bilberry anthocyanidins on angiogenesis

Phytotherapy Research, 2010
AbstractThe aim of this study was to examine the antiangiogenic properties and antioxidant activities (a) of the main anthocyanidins (delphinidin, cyanidin and malvidin) found as constituents in Vaccinium myrtillus (bilberry) anthocyanosides (VMA) and (b) of N‐acetyl‐l‐cysteine (NAC).

Estrogenic Activity of Naturally Occurring Anthocyanidins

Nutrition and Cancer, 2001
Anthocyanins, which are natural plant pigments from the flavonoid family, represent substantial constituents of the human diet. Because some other bioflavonoids are known to have estrogenic activity, the aim of this study was to determine the estrogenic activity of the anthocyanine aglycones.
