A phenolic compoud, (-)-epicatechin,was isolated from the stem bark of Garcinia bancana. The structure of
this compound was determined base on spectroscopic data such as including Uv, IR, 1-D, 2-D NMR, and
comparison with the reported data. Biological activity of this compound at free radical scavenging activity by 1,1-
diphenyl-2-picrylhydrazylradical (DPPH) and inhibitory xanthine oxidase(XO) activity showed that (-)- epicathechin
active at two methods with ICsovalue 8.1 and 8.6 j.lg/mLrespectively.
