Two new triterpenoid saponins were isolated from the 70% ethanol extract of the rhizome of Anemone amurensis, they are oleanolic acid 28-O-β-d-glucopyranosyl-(1 → 3)-α-l-rhamnopyranosyl-(1 → 4)-β-d-glucopyranosyl-(1 → 6)-β-d-glucopyranosyl ester (1) and 23,27-dihydroxy oleanolic acid 3-O-α-l-arabinopyranoside (2). The structures of 1 and 2 were elucidated(More)
Phytochemical investigation of the 70% EtOH extract of the rhizome of Anemone amurensis led to the isolation of two new oleanane-type triterpenoid saponins 1 and 2. Their structures were elucidated on the basis of chemical and spectral analysis, including 1D, 2D NMR data, and HR-ESI-MS. Compounds 1 and 2 were tested for cytotoxicities against two human(More)
