Article abstract of DOI:10.1248/cpb.44.1669

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.
