Raddeanalin, a new flavonoid glycoside from the leaves of Salix raddeana Laksh.

A new flavonoid glycoside, diosmetin 7-O-β-D-xylopyranosyl(1–6)-β-d-glucopyranoside, named raddeanalin (1), was isolated from the ethanolic extract of the leaves of Salix raddeana Laksh. together with three known compounds, kaempferol 3-O-glucoside (2), quercetin 3-O-glucoside (3) and quercetin 3-O-rutinoside (4). The structure of new compound was established by the spectral data and chemical properties.
