Abstract
A novel cycloartane-type glycoside, cyclocephaloside I (1) was isolate d from the roots of Astragalus microcephalus in addition to known glyc osides cyclocanthoside E (2) and astragaloside IV (3). The structure o f 1 was determined by spectral (IR, H-1 and C-13 NMR, and FABMS) and c hemical (acetylation) methods and established as 20,25-epoxy-3 beta-(b eta-D-xylopyranosyl)oxy-6 alpha-(beta-D-glucopyranosyl)oxy-cycloartane -16 beta,24 alpha-diol.
