摘要
A new pentacyclic triterpenoid was isolated from the leaves of Lagerstroemia indica and identified as 7-oxo-3 beta-hydroxy-5,20(29)diene-24-norlupane (1) along with three known triterpenoids, lup-20(29)-ene-1 beta,2 3 beta-triol (2), 21-hydroxylupa-1,12-dien-3-one (3), and lageflorin (4). Their structures were established on the basis of extensive spectroscopic analysis.
