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.

Structure–activity relationships of anthocyanidin glycosylation
Molecular Diversity, 2014This 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 ...

Structure and Mechanism of Anthocyanidin Synthase from Arabidopsis thaliana [PDF]
Structure, 2002 Flavonoids are common colorants in plants and have long-established biomedicinal properties. Anthocyanidin synthase (ANS), a 2-oxoglutarate iron-dependent oxygenase, catalyzes the penultimate step in the biosynthesis of the anthocyanin class of ...

Research progress of proanthocyanidins and anthocyanidins
Phytotherapy Research, 2023AbstractProanthocyanidins (PA) are polyphenol compounds that are widely distributed in the bark, fruit core, skin, or seeds of various plants. Anthocyanidins are water‐soluble natural pigments widely found in plants. They are all flavonoids, a major coloring substance in plants and fruits.

sPhospholipase A2 is inhibited by anthocyanidins
Journal of Neural Transmission, 2009Epidemiological studies suggest that nutritional antioxidants may reduce the incidence of neurodegenerative disorders and age-related cognitive decline. Specifically, protection against oxidative stress and inflammation has served as a rationale for promoting diets rich in vegetables and fruits. The present study addresses secretory phospholipase A(2) (

Conversion of Leucoanthocyanins into the Corresponding Anthocyanidins
Science, 1964Purified 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.
