[The megastigman glycosides from herb of Potentilla multifida].
ABSTRACT To investigate the chemical constituents of Potentilla multifida.
Various chromatographic techniques were employed for isolation and purification of the constituents. The structures were elucidated by spectral analysis.
Four megastigmane glycosides were isolated from P. multifida and their structures were identified as citroside A (1), icariside B1 (2), (6S,7E,9R)-roseoside (3), (6S,7E,9R)-vomifoliol-9-O-beta-D-xylopyranosyl-(1-->6)-O-beta-D-glucopyranoside (4), respectively.
All compounds were obtained from the genus Potentilla for the first time.
