From the leaves of Salpichroa origanifolia three new withanolides, (20S,22R,24S,25S,26R)-5alpha,6alpha:22,26:24,25-triepoxy-15,26-dihydroxy-17(13-->18)-abeo-ergosta-2,13,15,17-tetraen-1-one (salpichrolide G, 1), (20S,22R,24S,25R)-5alpha,6alpha:22,26-diepoxy-24,25,26-trihydroxy-17(13-->18)-abeo-ergosta-2,13,15,17-tetraen-1-one (salpichrolide H, 2), and (20S,22R,25S)-5alpha,6alpha:22,26-diepoxy-25,26-dihydroxy-17(13-->18)-abeo-ergosta-2,13,15,17,23-pentaen-1-one (salpichrolide I, 3), were isolated and characterized by spectroscopic methods and with the aid of molecular modeling. The latter two compounds were obtained as an epimeric mixture at C-26.
