Authors:B A Imomnazarov  M I Isaev
Abstract:In addition to cyclosieversigenin, beta-sitosterol coprod-D-glucopyranoside, and cyclocarposide, we have isolated another three glycosides of triterpene nature from the epigeal part of the plantAstragalus coluteocarpus Boiss. (Leguminosae). On the basis of chemical transformations and spectral characteristics, the structure of one of the new glycosides, which we have called cyclocarposide B, has been established as 20R,24S-epoxycycloartane-3beta,6agr,16beta,25-tetraol 6-O-agr-L-(2-O-acetylrhamnopyranoside) 3-O-beta-D-xylopyranoside.Institute of Chemistry of Plant Substances, Uzbekistan Academy of Sciences, Tashkent. Translated from Khimiya Prirodnykh Soedinenii, No. 2, pp. 227–231, March–April, 1992.
