Flavonoids of Ochna afzelii

Phytochemistry. 2003 Sep;64(2):661-5. doi: 10.1016/s0031-9422(03)00267-x.

Abstract

Fractionation of the methanolic extract of Ochna afzelii stem bark has resulted in the isolation of two biflavonoids afzelones A and B along with five known flavonoids, calodenins A and B, afzelone C, 4',5-dimethoxy-6,7-methylenedioxyisoflavone, 4',5,7-trimethoxyisoflavone and the glucoside lanceoloside A. Their structures were determined using spectroscopic and chemical methods.
