title: A new bufadienolide obtained from the biotransformation of cinobufagin by Alternaria alternata.
abstract: A new bufadienolide, 12-oxo-desacetylcinobufagin, was obtained from the biotransformation of cinobufagin by Alternaria alternata in fairly low yield (0.34%). Its structure was established on the basis of (1)H-NMR, (13)C-NMR, 2D-NMR, and MS spectral data.
