Abstract:Three new triterpene glycosides of the oleanane series — melilotosides A, B, and C — and the nonglycosylated soyasapogenol B have been isolated from the roots of the plant Melilotus albus Medik. (Leguminosae). The structures of the glycosides have been shown on the basis of chemical transformations and spectral results. Melilotoside A has the structure of soyasapogenol B 3-O-agr-L-arabinopyranoside, melilotoside B that of soyasapogenol B 3-O-O-beta-D-galactopyranosyl-(1rarr2)-agr-L-arabinopyranoside], and melilotoside C that of soyasapogenol B 3-O-O-agr-L-rhamnopyranosyl-(1rarr2)-O-beta-D-galactopyranosyl-(1rarr2)-agr-L-arabinopyranoside.Translated from Khimiya Prirodnykh Soedinenii, No. 6, pp. 756–762, November–December, 1994.
