Abstract

Structures of two new ergostane-type steroids which occur in the leaves of a variety of Physalis pubescens L. (Solanaceae) growing in India were established by spectral analysis and chemical transformations. Physapubenolide (2a) is (20S,22R)-15α-acetoxy-5β,6β-epoxy-4β,14β- dihydroxy-1-oxo-witha-2,24-dienolide. Pubescenin (6a) is (20S,22R)-24,25-epoxy- 1α-hydroxy-3β-(Ȯ-β-D-glucopyranosyl) with-5-enolide.
