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

27-Caffeoyloxy-3-β-hydroxyolean-12-en-28-oic acid (1) and rhoipteleic acids A (2) and B (3), diastereomeric esters composed of two triterpene units and enantiomeric lignan carboxylic acids, were isolated from the bark of Rhoiptelea chiliantha.The structures have been determined on the basis of spectroscopic and chemical evidence including biomimetic synthesis of 2 and 3 from 1.
