    New sarverogenin and isosarverogenin glycosides from Cryptolepis buchanani (Asclepiadaceae).[Reference: WebLink]

    METHODS AND RESULTS:
    The structures of Cryptanoside A and cryptanoside C, the major cardenolide glycosides of the leaves and roots respectively of Cryptolepis buchanani, have been established as sarverogenin 3-O-α-L-oleandroside and sarverogenin 3-O-[β-D-glucopyranosyl-(1→4)-α-L-oleandroside] on the basis of their 1H and 13C NMR spectroscopic properties and chemical correlation with sarverogenin.
    CONCLUSIONS:
    Cryptanoside B, a minor constituent of the leaf extract, is isosarverogenin 3-O-α-L-oleandroside. Cryptanoside D, the corresponding isosarverogenin derivative of cryptanoside C, was isolated, as its acetate, from the crude product of acetylation of cryptanoside C. Germanicol docosanoate is a major constituent of the root extract.
