Validation of a New HPLC-DAD Method to Quantify 3-Deoxyanthocyanidins Based on Carajurin in Medicinal Plants and for Chemical Ecology Studies

Plants, 2023
Anthocyanidins are found in nature mainly as pelargonidin, cyanidin, peonidin, delphinidin, petunidin, and malvidin derivatives. These compounds are found free or as glycoside derivatives which are responsible for the color (red, blue, and violet) of ...

Are anthocyanidins the immediate products of anthocyanidin synthase?

Chemical Communications, 2000
Anthocyanidin synthase catalyses the in vitro conversion of its natural substrate, leucocyanidin, to cis- and trans-dihydroquercetin, quercetin and a small amount of cyanidin; incubation of trans-dihydroquercetin gave quercetin.

Synthetic anthocyanidins and their antioxidant properties [PDF]

SpringerPlus, 2015
Anthocyanidins were synthesized to study the effect of methoxy substitution on the B ring to their antioxidant property. Comparative FRAP studies show 2'- and 4'-methoxy substituents have higher antioxidant activities, which may be attributed to both resonance and inductive effects.Graphical abstract:Anthocyanidins as reducing agents.
