Two new compounds 7-hydroxy-5-O-(β-D-glucopyranoside)flavan(1)and(Z)-4′,6′-dihydroxy-2′-O-(β-D-glucopyranoside) chalcune(2),along with eight known compounds,were isolated from the stem bark of Drypetes parvifolia(Euphorbiaceae).Their structures were established on the basis of spectroscopic analysis and chemical evidence.
