Abstract

Two benzoyl esters, benzyl 2,6-dimethoxybenzoate (1), benzyl 2,5-dihydroxybenzoate (2), together with three flavones, 5-hydroxy-3,4’,7-trimethoxyflavone (3), 3,5-dihydroxy-4’,7-dimethoxyflavone (4) and 5,6-dihydroxy-3,4’,7-trimethoxyflavone (5), were isolated from the ethyl acetate extract of Polyalthia parviflora leaves. Their structures were elucidated on the basis of spectroscopic analysis and comparisons with related known compounds.
