Abstract

Further examination of the methanolic extract of the roots of Cassia pudibunda led to isolation of four new angular γ-naphthopyrones identified as 10-demethylflavaspe-rone (1), 10-demethylflavasperone-10-sulphate (2), 10-demethylflavasperone-10-O-β-D-apiof uranosyl-(1→-6)-O-β-D-glucopy-ranoside (3), and cassiapyrone-10-sulphate (7-methyl-10-deme-thylflavasperone-10-sulphate) (4). The antimicrobial activity of the compounds is also reported.
