Abstract

A new cardenolide named cryptosin was isolated from the leaves of Cryptolepis buchanani. By spectral studies and single crystal X-ray crystallography, cryptosin was found to possess a novel structure. The structure thus established was 3β-(d-deoxy glucose-oxy)-14β,11β-dihydroxy-7α,8α-epoxy-12-oxo-5β- card-20 (22)-enolide.
