From the stem bark of Shorea hemsleyana (Dipterocarpaceae), four new stilbenoids with one or two dihydrofuran ring(s) [hemsleyanols C, D, hemsleyanosides E, F, and (-)-ampelopsin H] and a new stilbenoid with a carbonyl group (hemsleyanol E) were isolated. The structures including the relative configuration were elucidated on the basis of spectroscopic and chemical evidence.
