A new triterpene glycoside from Anemone raddeana

A new triterpene glycoside, 27-hydroxyoleanolic acid-3-O-α-L-arabinopyranoyl-(1→3)-α-Lrhamnopyranosyl-(1→2)-α-L-arabinopyranoside-28-O-[α-L-rhamnopyranosyl-(1→4)-β-D-glucopyranosyl-(1→6)]--D-glucopyranosyl ester, was isolated from the rhizomes of Anemone raddeana. The structure was identified by physichemical properties and spectral analysis, especially 2D NMR techinques.
