title: Microbial transformation of dehydrocostuslactone by Mucor polymorphosporus.
abstract: Biotransformation of dehydrocostuslactone (1) by Mucor polymorphosporus yielded four compounds, and their structures were identified as 11alpha,13-dihydrodehydrocostuslactone (2), 3alpha-hydroxy-11alpha,13-dihydrodehydrocostuslactone (3), 3beta-hydroxy-4beta,15,11alpha,13-tetrahydrodehydrocostuslactone (4) and 2beta-hydroxyl-11alpha,13-dihydrodehydrocostuslactone (5), respectively, on the basis of their spectral data. Among them, compound 5 is a new compound.
