摘要：

The leaves of Datura ferox yielded a new withanolide, 5 alpha,12 alpha,15 beta-trihydroxy-6 alpha,7 alpha-epoxy-1-oxo-22R-witha-2,24-dienolide (15 beta-hydroxynicandrin B), in addition to nicandrin B, withanicandrin, withastramonolide and withametelin E previously reported from Datura species. The structure and stereochemistry of 15 beta-hydroxynicandrin B was established on the basis of spectroscopic evidence and molecular modelling.
