Anthocyanidins from leucoanthocyanidins
Phytochemistry, 1965High acid strength and small amounts of iron have been effectively combined to improve the yield of anthocyanidins from leucoanthocyanidins over that obtained by currently used methods. An improved method for routine estimation of leucoanthocyanidins in plant extracts is outlined.

Computational aspects of anthocyanidins and anthocyanins: A review
Food Chemistry, 2019Anthocyanins 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, 2020We 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.

Inhibitory actions of bilberry anthocyanidins on angiogenesis
Phytotherapy Research, 2010AbstractThe 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, 2001Anthocyanins, 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.

Anthocyanidin variation in Clarkia
Biochemical Systematics and Ecology, 1986Abstract Previous reports of anthocyanin variation in Clarkia indicated intersectional differentiation, suggesting an additional marker for evaluating infrageneric relationships. Therefore, an investigation of anthocyanidin content of 19 species representing seven of the 10 sections was conducted.

Inhibition of proteasome activity by anthocyanins and anthocyanidins
Biochemical and Biophysical Research Communications, 2008Recent reports have demonstrated multiple benefits associated with the consumption of berry fruits, including a decreased vulnerability to oxidative stress, reduced ischemic brain damage, protection of neurons from stroke-induced damage and the reversal of age-related changes in brain and behaviour.

A DFT investigation of anthocyanidins
Chemical Physics Letters, 2005Abstract A theoretical analysis of anthocyanidins, a class of natural plant pigments, has been conducted using density functional theory at the B3LYP/6-31G(d) level. It is found that these compounds are non-planar, with the 2-phenyl ring twisted relative to the benzopyrylium rings.

Phytochemistry, 1969
Abstract During the conversion of leucoanthocyanidins into anthocyanidins with alcoholic HCl small amounts of additional anthocyanidins are formed, which appear to be simple ethers of the anthocyanidins and the alcohol used in the medium. The chromatographic characteristics of such derivatives produced from different leucoanthocyanidins have been ...
