Abstract
Five new withanolides, 5 alpha ,6 alpha :22,26: 24,25-triepoxy-16 alpha ,26
-dihydroxy-18(13 --> 17)-abeo-ergosta-2, 13-dien-1-one (salpichrolide N, 1)
, 5 alpha ,6 alpha :22,26:24,25-triepoxi-15 alpha ,26-dihydroxyergosta-2,16
-dien-1-one (salpichrolide L, 2), 5 alpha ,6 alpha :22,26-diepoxi-24,25,26-
trihydroxy-17(13 --> 18)-abeo-ergosta-2,13,15,17-tetrarn-1-one (salpichroli
de M, 3a), 5 alpha ,6 alpha :22,25:22,26-triepoxy-24-hydroxy-17(13 --> 18)-
abeo-ergosta-2,13,15,17-tetraen-1-one (salpichrolide J, 4), and 5 alpha ,6
alpha :22,26-diepoxy-22,24,25-trihydroxy-17(13 --> 18)-abeo-ergosta-2,13,15
,17-tetraen-1-one (salpichrolide K, 5), were isolated from the leaves of Sa
lpichroa origanifolia and characterized by a combination of spectroscopic (
1D and 2D NMR, MS) and chemical methods.
