Abstract

The structure of withaminimin, a new ergostane-type steroid from Physalis minima, was established by spectral analysis (¹H and ¹³C NMR, MS) and chemical transformations, as (20S,22R)-15α-acetoxy-5α,6β,14α-trihydroxy-1-oxowitha-2,16,24-trienolide. An unusual MH₂O⁺ quasi-molecular ion was observed in the chemical ionization mass spectrum of the natural product.
