摘要：

Betulinic acid (I), a pentacyclic triterpene, on derivatization gives six compounds: 3 beta-hydroxylup-20(29)-en-28 oic acid methyl ester (II), 3 beta-acetoxylup-20(29)-en-28-oic acid (III), 3 beta-allyloxylup-20(29)-en-28-oic acid (TV), 3 beta-p-methylcinnamatoxylup-20(29)-en-28-oic acid (V), 3 beta-p-methoxycinnamatoxylup-20(29)-en-28-oic acid (VI), and 3 beta-tri-O-methylgallotoxylup-20(29)-en-28 acid (VII). Their antifeedent activity against the agricultural pest tobacco caterpillar larvae (Spodoptera litura F) in a no-choice laboratory study showed the active compounds are V, VI, and VII.
