摘要：

Four new withanolides [1-4] have been isolated from the aerial parts of Jaborosa sativa. Jaborosalactones R [1], S [2], and T [3] contain a hemiketal (or ketal) ring formed between a 21-hydroxyl and a 12-ketone and the characteristic delta-lactone side-chain of the withanolides. Jaborosalactone U [4] possesses an epoxy-gamma-lactone side-chain and was identified as the 24,25-epoxy analogue of trechonolide A [5].
