Biotransformation of Digitoxin by Aspergillus Ochraceus
Biotransformations of natural products have great potential for preparation of lead compounds. In this paper, the biotransformation of digitoxin (1) with Aspergillus ochraceus afforded two products, identified as digitoxigenin (2) and sarmentogenin (3) by HR-MS, 1H-NMR and 13C-NMR.
