[Structure of pingbeidinoside, an alkaloid isolated from the stems and leaves of Fritillaria ussuriensis Maxim].
A new steroid alkaloid glucoside, pingbeidinoside, was isolated from the stem and leaf of Fritillaria ussuriensis Maxim by column chromatographic techniques. On the basis of the IR, MS, 1HNMR and 13CNMR spectra of pingpeidinoside and products of its transformation, the structure of pingbeidinoside has been established as 3 beta,16 alpha,20-trihydroxy-delta 5-22,26-epiminocholestane-25-O-beta-D- glucoside.
