Two new isoflavone triglycosides from the small branches of Sophora japonica.
Two new isoflavone triglycosides, genistein 4'-O-(6''-O-alpha-L-rhamnopyranosyl)-beta-sophoroside (1), and genistein 4'-O-(6'''-O-alpha-L-rhamnopyranosyl)-beta-sophoroside (2), together with five known compounds, namely, sophorabioside, genistin, rutin, quercetin 3-O-beta-D-glucopyranoside, and kaempferol 3-O-beta-D-glucopyranoside, were isolated from the small branches of Sophora japonica L. Their structures were elucidated on the basis of spectroscopic analyses and chemical evidence.
