Abstract

Chromatography of an ethyl acetate extract of defatted Pterocarpus Marsupium Roxb. (Leguminosae) heartwood over silica gel afforded marsupsin (1) which was characterized as a new 2-hydroxy-2-benzyl-3(2H)-benzofuranone by a consideration of physicochemical data and conversion to triacetylmarsupsin (3) and trimethylmarsupsin (tetramethylmaesopsin) (2).
