Two new stilbene glucosides [(+)-alpha-viniferin 13b-O-beta-glucopyranoside
and resveratrol 12-C-beta-glucopyranoside] and two new resveratrol oligome
rs, hemsleyanols A and B, were isolated from the bark of Shorea hemsleyana
ana along with four known resveratrol oligomers. The structures of the isol
ates, including the relative configurations, were established by spectrosco
pic data involving long-range coupling and nuclear Overhauser effect experi
ments.
