Abstract
Five triterpene-lignan esters, chilianthins A-E (2-6) and a triterpene -naphthalene carboxylic acid ester, chilianthin F (7), were isolated f rom the bark of Rhoiptelea chiliantha DIELS et HAND.-MAZZ. (Rhoiptelea ceae), together with a known triterpene caffeate, 27-caffeoyloxy-3 bet a-hydroxyolean-12-en-28-oic acid (myriceric acid B, 1). Their structur es were elucidated on the basis of spectroscopic and chemical evidence . Chilianthins A (2), B (3), C (4) and E (6) were biomimetically synth esized from 1 by oxidative coupling.
