【 摘 要 】

The novel (-)-7,8,3',4'-trihydroxy-8-(3'',7''-dimethyl-octa-2'',6''-dienoyl)-flavanone was isolated from the EtOH extract from the roots of Harpalyce brasiliana (Leguminosae) together with the known pterocarpans (-)-2-geranyl-3-hydroxy-8,9-methylenedioxypterocarpan, harpalicin, medicarpin, maackiain and cabenegrins A-I and A-II. The isolated metabolites were characterized on the basis of spectroscopic data, mainly 1D and 2D NMR.
