Özet
A novel cycloartane-type glycoside, cyclocephaloside I (1) was isolated from the roots of Astragalus microcephalus in addition to known glycosides cyclocanthoside E (2) and astragaloside IV (3). The structure of 1 was determined by spectral (IR, H-1 and C-13 NMR, and FABMS) and chemical (acetylation) methods and established as 20,25-epoxy-3 beta-(beta-D-xylopyranosyl)oxy-6 alpha-(beta-D-glucopyranosyl)oxy-cycloartane-16 beta,24 alpha-diol.
