摘要：

Two new aporphinoid alkaloids. lettowianthine and 11-methoxylettowianthine were isolated from the root bark of Lettowianthus stellatus, together with the new sesquiterpene 11-hydroxyguaia-4,6-diene and the known compounds liriodenine, (Z)-7-octadeeen-9-ynoic acid, methyl (2E,6E,10R)-10,11-epoxy-3,7,11-trimethyl-2,6-dodecadienoate, methyl (2E,6E,10R)-10,11-dihydroxy-3,7,11-trimethyl-2,6-dodecadienoate, and 3,4,5,-trimethoxyphenol. The structure elucidation was achieved by spectroscopic methods. (c) 2000 Published by Elsevier Science Ltd. All rights reserved.
