Abstract

Bergenin, a dihydroisocoumarin derivative of glucopyranosyl gallic acid had been isolated for the first time from ethyl acetate extracts of the heartwood and tree bark, together with (-)-α-viniferin from the tree bark of Shorea stenoptera. The structure of bergenin was elucidated based on analysis of spectroscopic data UV, IR, MS, 1H and 13C NMR. Bergenin showed weak cytotoxic activity against murine leukemia P-388 cells (IC50 >100 μg/mL), and also weak toxicity against Artemia salina shrimps (LC50 >500 μg/mL).
