Abstract

3-Oxo-oleanolic acid (1) was biotransformed in growing cultures of the fungus Absidia glauca, resulting in three novel hydroxylated metabolites, identified as 1β-hydroxy-3-oxo-olean-11-en-28,13-lactone (2), 1β,11α-dihydroxy-3-oxo-olean-12-en-28-oic acid (3), and 1β,11α,21β-trihydroxy-3-oxo-olean-12-en-28-oic acid (4).
