Abstract
Four compounds of cycloartane nature have been isolated from the roots ofAstragalus globiceps Bunge. Their structures have been established on the basis of spectral characteristics and chemical transformations. Cyclosieversiosides E and F and astrasieversianin III have been described previously. Cycloglobiceposide A has now been investigated for the first time and found to be 20R, 24S-epoxycycloartane-3β, 6α, 16β, 25-tetraol 3-0-(2′-O-acetyl-β-D-xylopyranoside) 6′-O-acetyl-β-D-glucopyranoside).
