title: Flavonoid glycosides and saponins from Astragalus shikokianus.
abstract: A new flavonol glycoside, kaempferol 3-O-alpha-L-rhamnopyranosyl -(1-->6)-[alpha-L-rhamnopyranosyl-(1-->2)]-beta-D-galactopyranosyl-7-O-a lpha-L-rhamnopyranoside, named astrasikokioside I, was isolated from aerial part of Astragalus shikokianus, together with two flavonol glycosides, kaempferol 3-O-alpha-L-rhamnopyranosyl-(1-->2)-beta-D-galactopyranosyl-7-O-alpha-L- rhamnopyranoside, robinin, and three triterpenoid glycosides, soyasaponin I, sophoraflavoside II and robinioside E.
