A new acetylated flavanol, 3,7-O-diacetyl (–)-epicatechin (3), and seven known flavanol derivatives, (–)-epicatechin (1), 3-O-acetyl (–)-epicatechin (2), 3,3′,4′,5,7-O-pentaacetyl (–)-epicatechin (4), (+)-afzelechin (5), (+)-catechin (6), cinchonain Ib (7), and proanthocyanidin B2 (8), were isolated from the stems and twigs of the mangrove plant Rhizophora stylosa and identified. The crude extract, the different fractions and all of the purified compounds were evaluated for DPPH radical scavenging activity. View Full-Text
