Abstract: Withanolide D, the major component of the leaves of Withania somnifera chemotype II, is a steroidal lactone of the withanolide type, isomeric with withaferin A. It has been identified as 5, 6β-epoxy-4β, 20α-dihydroxy-1-oxo-(5β)witha-2, 24-dienolide. The structure has been elucidated by NMR measurements and by chemical degradation to 4β-acetoxy-5,6β-epoxy (5β) pregnan-1, 20-dione.
