A new triterpene glycoside of the oleanane series — melilotoside D — has been isolated from the roots of plantMelilotus albus Medik. (Leguminosae). Melilotoside D is a tetraoside of soyasapogenol B. Its structure has been shown on the basis of chemical transformations and spectral characteristics as soyasapogenol B 3-O-{[O-α-L-rhamnopyranosyl-(1→2)]-[O-α-L-arabinopyranosyl-(1→3)]-O-β-D-galactopyranosyl-(1→2)-α-L-arabinopyranoside}. 相似文献

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-α-L-arabinopyranoside, melilotoside B that of soyasapogenol B 3-O-[O-β-D-galactopyranosyl-(1→2)-α-L-arabinopyranoside], and melilotoside C that of soyasapogenol B 3-O-[O-α-L-rhamnopyranosyl-(1→2)-O-β-D-galactopyranosyl-(1→2)-α-L-arabinopyranoside. 相似文献

In addition to known glycosides of the cycloartane series — cyclosieversiosides A, E, and F — a new acetylated compound of glycosidic nature — cycloexoside — has been isolated from the roots ofAstragalus exilis A. Kor. (Leguminosae). On the basis of chemical transformations and spectral characteristics, the structure of cycloexoside has been established as 20R,24S-epoxycycloartane-3,6,16,25-tetrol 3-O-(2,3-di-O-acetyl--D-xylopyranoside).Institute of Chemistry of Plant Substances, Uzbekistan Academy of Sciences, Tashkent.
