Chemosystematic Studies in the Chrysobalanaceae. I. Flavonoids in Parinari (original) (raw)

This study explores the flavonoid composition in 31 species of the genus Parinari from Asia, Africa, and the Neotropics. The findings indicate that flavonol glycosides, specifically myricetin, quercetin, and kaempferol, are predominant in these species, with distinct chemical variations observed among African and Neotropical groups. The research suggests a phytogeographic evolution in the Chrysobalanaceae, positing that African species with myricetin represent a primitive ancestral group, giving rise to non-myricetin groups that expanded geographically.
