Abstract
Biological and Phytochemical screening of heartwood of Acacia catechu was studied.
Phytocostituents found were Sterols, Flavones Aglycones, Tannins and Polyphenols. The
column chromatography of diethyl ether fractions result in the isolation of β-Sitosterol
(Ac1), Quercetin (Ac4), (+) Catechin (Ac6). Other four compounds Ac2, Ac3, Ac5, Ac7
whose work is on progress, were also isolated. Antibacterial screening, antifungal
screening and brine shrimp bioassay of different fractions showed that hexane, chloroform,
diethyl ether, ethyl acetate and methanol fraction were biologically active. In brine shrimp
bioassay only diethyl ether, ethyl acetate, and methanol fraction showed activity.
