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.

Bioactive 6S-styryllactone constituents of Polyalthia parviflora.
The structure-activity relationship of the compounds in an in vitro anti-inflammatory assay revealed the 6S-styryllactones to be more potent than the 6R derivatives, however, the effect was opposite regarding their cytotoxic activity.
Chemical constituents of Polyalthia parviflora stem
From the stem of Polyalthia parviflora, four compounds were isolated, including p-hydroxyphenylethyl p-coumarate (1), p-hydroxyphenylethyl ferulate (2), dehydrodiscretamine (3) and (−)-discretamine
