Abstract
Objective To study the chemical constituents of the leaves of Crataegus pinnatifida Bge.Methods Seven compounds were isolated by chromatography on silica gel column,Sephadex LH-20,ODS chromatography column,PHPLC and established on the basis of physico-chemical constants and spectroscopic analysis.Results Seven compounds were isolated from 80% ethanol-water extract and their structures were identified as 18,19-seco,2α,3β,-dihydroxy-19-oxo-urs-11,13(18)-dien-28-oic acid(1),3,9-dihydroxy-megastigma-5-ene(2),(3S,5R,6R,7E)-megatsigmane-7-ene-3-hydroxy-5,6-epoxy-9-O-β-D-glucopyranoside(3),(Z)-3-hexenyl-6-O-β-D-xylopyranosyl-(1″-6′)-β-D-glucopyranoside(β-primeveroside)(4),benzoic acid(5),p-hydroxy-phenylpropionic acid(6),trans-p-hydroxy cinamic acid(7).Conclusions Compounds 14 are isolated from this genus for the first time and compounds 57 are isolated from this plant for the first time.
