title: [Studies on the structure of diglycoside from Dregea sinensis var. corrugata].
abstract: A new diglycoside, named dregeoside, was isolated from the rhizomes of Dregea sinensis var corrugata (Asclepiadaceae). The structure of dregeoside was deduced on the basis of chemical and spectral evidence as 12, 20-di-O-isovaleryl tomentogenin-3-O-alpha-L-oleandropyranosyl-(1----4)- alpha-L-oleandropyranoside.
