Key Word Index-Xanthocercis zambesiaca; Leguminosae; 7,8-dioxyisoflavonoids; α-hydroxydihydrochalcones; 1,3-diarylpropan-2-ones.Abstract-In addition to some previously described 7,8-dioxy-isoflavonoids and 2-benzylbenzofuran-3(2H)-ones the heartwood of Xanthocercis zambesiaca has been shown to contain 7,8,3'-trihydroxy-4'-methoxyisoflavone.These are accompained by the novel α,3,4,4'-tetrahydroxy-2'-methoxydihydrochalcone and its 3-deoxy analogue, the latter of which presumably served as biogenetic precursor for the unique 1-hydroxy-3-(4-hydroxyphenyl)-1-(4-hydroxy-2-methoxyphenyl) propan-2-one and its 1-deoxy analogue.Such possible biosynthetic relationship was demonstrated by the facile in vitro transformations of the appropriate α-hydroxydihydrochalcone into the different 1,3-diarylpropan-2-ones.

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).
