Abstract
The biotransformation of a pentacyclic triterpene, oleanolic acid (1), with Fusarium lini afforded two oxidative metabolites, 2α,3β-dihydroxyolean-12-en-28-oic acid (2), and 2α,3β,11β-trihydroxyolean-12-en-28-oic acid (3). Metabolite 3 was found to be a new compound. The structures were characterized on the basis of spectroscopic studies. These metabolites exhibited a potent inhibition of α-glucosidase enzyme.
