TERITERPENE GLYCOSIDES OF Astragalus AND THEIR GENINS XXXII. CYCLOCARPOSIDE FROM Astragalus coluteocarpus

Article abstract of DOI:10.1007/BF00601289

A new triterpene glycoside of the cycloartane series, which has been called cyclocarposide, has been isolated from the epigeal part of the plant Astragalus coluteocarpus Boiss. (Leguminosae).The structure of cyclocarposide has been established on the basis of chemical transformations and spectral characteristics as 20R,24S-epoxycycloartane-3β,6α,16β,25-tetraol 6-O-α-L-rhamnopyranoside 3-O-α-D-xylopyranoside.
