摘要

Preparative-scale fermentation of the known C-nor-D-homosteroidal jerveratrum alkaloid jervine with Cunninghamella elegans (ATCC 9245) has resulted in the isolation of (-)-jervinone as the major metabolite. In addition, C. elegans ATCC 9245 was able to epimerize C-3 of jervine, producing 3-epi-jervine. This epimerization reaction was similar to that reported for tomatidine, the known spirosolane-type Solanum alkaloid. The structure elucidation of both metabolites was based primarily on 1D- and 2D-NMR analyses.
