Abstract

Two withanolides have been isolated from the epigeal part ofPhysalis viscosa L. One of them with the compositions C28H38O8 has been identified as 4β-hydroxy-withanolide E, and for the second, which has been called physanolide, the structure of 14α,17β,20R-trihydroxy-1,4-dioxo-22R-witha-5,24-dienolide has been proposed on the basis of its UV, IR, PMR, and mass spectra, and also the results of a partial synthesis of 14α-hydroxyandrost-5-ene-1,4,17-trione, obtained by its oxidation.
