Abstract
The chloroform extract of the fresh berries of Withania somnifera has been investigated to afford stigmasterol, its glucoside, withanone, 27-hydroxy withanolide A along with two new withanolides, namely, iso-withanone (1) and 6α,7α-epoxy-1α,3β ,5α-trihydroxy-witha-24-enolide (2). Compound 1 possesses an uncommon 17α-oriented side chain whereas compound 2 has 1α,3β - dihydroxy group which is a molecule of biogenetic significance for withasteroids.
