Triterpene glycosides of Astragalus and their genins. XXVII. X-ray structural investigation of cyclogalegigenin

It has been shown by x-ray structural analysis that cyclogalegigenin has the 20S,24R stereochemistry and, consequently, is 20S,24R-epoxycycloartane-3,6,16,25-tetraol. Cyclosieversigenin is 20R,24S-epoxycycloartane-3,6,16,-25-tetraol.Institute of Applied Physics, Acadmy of Sciences of the Moldavian SSR, Kishinev.
