Abstract

The EtOAC extractable constituents of the bark of C. haematocephala were active against selected bacteria. Fractionation by chromatographic methods, gave known compounds p-hydroxybenzoic acid, caffeic acid, protocatechuic acid, astilbin, neo-isoastilbin, and catechin-3-O-rhamnoiside, which showed varied antibacterial activity. In addition the non-active n-C6H14 fraction gave lupeol and betulinic acid.

Key Words: Calliandra. heamatocephala Hassk, Mimosaaceae, antibacterial, p-hydroxybenzoic acid, caffeic acid, protocatechuic acid, astilbin, neo-isoastilbin, and catechin-3-rhamnoside
