Corosolic acid, a pentacyclic triterpene acid, attracted more and more attention because of the significant anti-diabetes activity. Biocatalysis was applied to modify the structure of corosolic acid to increase the structural diversity of corosolic acid and lay the foundation for screening derivatives with novel structure or better activity. A novel corosolic acid derivative was synthesized by endophytic fungus Umbelopsis isabellina. The structure of the new compound was established by HR-ESIMS and NMR spectrum.

Key words: corosolic acid, biocatalysis, hydroxylation, 2α,3β,7β-trihydroxy-urs-11-en-28,13-lactone
