摘要：

Three new 16-oxygenated withanolides have been isolated from the leaves of Discopodium penninervium together with the known withanolide, jaborosalactone-L. The new compounds were identified, primarily on the basis of NMR spectroscopy, as 16alpha-acetoxy-5beta,6beta-epoxy-17alpha-hydroxy-1-oxowitha-2,24-dienolide,5beta,6beta-epoxy-16alpha,17alpha-dihydroxy-1-oxowitha-2,24-dienolide and 16alpha-acetoxy-5beta,6beta-epoxy-1-oxowitha-2,24-dienolide.
