Abstract
From the leaves of Salpichroa origanifolia collected in winter two new ergostane derivatives related to withanolides, 5,6 alpha-epoxy-22-for myloxy-27-nor-17(13-->18)abeo-5 alpha- ergosta-2,13,15,17-tetraene-1,2 5-dione and 5 alpha,6 eta-dihydroxy-22-formyloxy-27-nor-17(13-->18)abe o- 5 alpha-ergosta-2,13,15,17-tetraene-1,25-dione were isolated and ch aracterized by spectroscopic methods.
