Abstract

Three stilbene derivatives, namely lunularin (1), oxyresveratrol (2), and andalasin A (3), together with 2-arylbenzofuran derivative, moracin M (4), coumarin derivative, umbelliferon (5), and β-resolcylaldehyde, were isolated from Morus macroura Miq. (Moraceae), a rare spesies found in West Sumatera and endemic to Indonesia. The structures of all these compounds were elucidated based on physical and spectroscopic data.

Abstract

Two oligostilbenoid, namely stenophyllol B (1) and hopeaphenol (2) had been isolated from the stem bark of Vatica umbonata Burck (Dipterocarpaceae). The structure of both compounds were elucidated based on spectroscopic data. Both compounds exhibited strong toxicity againts murine leucaemia cell P-388 with IC50 : 8,5 μg/ml and 2,9 μg/ml, respectively.

Abstract

Two dimers of stilbenoids, (-)-balanocarpol (4), and (-)-ampelopsin A (5), along with a tetramer (-)-hopeaphenol (6) were isolated from the stem bark of Shorea multiflora Burck (Dipterocarpaceae), locally known as Meranti. Their structures were determined by physical and UV, IR, 1H-NMR, and 13C-NMR spectroscopic data.
