Two New Glycosides from Astragalus caprinus

A new glycoside of flavonol (1) and a new glycoside of a cycloartane-type triterpene (2) were isolated from the leaves and the roots of Astragalus caprinus, respectively. Their structures were elucidated in turn by spectroscopic data interpretation as 3-O-{[β-d-xylopyranosyl(1→3)-α-l-rhamnopyranosyl(1→6)][β-d-apiofuranosyl(1→2)]}-β-d-galactopyranosyl kaempferol (1) and 3-O-(β-d-xylopyranosyl)-24-O-(β-d-glucopyranosyl)-20,25-epoxycycloartane-3β,6α,16β,24α-tetrol (2).
