Isolation and Structure of Neriucoumaric and Isoneriucoumaric Acids from the Leaves of Nerium oleander.
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 3beta-hydroxy-2alpha-cis- P-coumaryloxy-urs-12-en-28-oic acid and 3beta-hydroxy-2alpha- TRANS- P-coumaryloxy-urs-12-en-28-oic acid respectively, through chemical and spectroscopic methods.
