Abstract
Two new coumaryloxy triterpenoids, neriucoumaric and isoneriucoumaric acids, have been isolated from fresh, undried and uncrushed leaves of Nerium oleander and their structures established as 3β-hydroxy-2α-cis-p-coumaryloxy-urs-12-en-28-oic acid and 3β-hydroxy-2α-trans-p-coumaryloxy-urs-12-en-28-oic acid respectively, through chemical and spectroscopic methods.This publication has 3 references indexed in Scilit:
