[Studies on triterpenoid saponins in the rhizome of Anemone flaccida].
OBJECTIVE
To study the triterpenoid saponins in the rhizome of Anemone flaccida.


METHODS
The constituents were separated with various chromatographic techniques and their structures were elucidated by means of physicochemical properties and the analysis of their spectral datas.


RESULTS
Five compounds were isolated and identified as 3-O-beta-D-glucuronypyranosyl-oleanolic acid-28-O-alpha-L-rhamnopyranosyl (1 --> 4)-beta-D-glucopyranosyl(1 --> 6)-beta-D-glucopyra noside (1), 3-O-beta-D-glucuronypyranosyl-oleanolic acid-28-O-beta-D-glucopyranosyl (1 --> 6)-beta-D-glucopyranoside (2), 3-O-alpha-L-rhamnopyranosy (1 --> 2)-beta-D-glucopyranosyl-oleanolic acid-28-O-alpha-L-rhamnopyranosyl (1 --> 4)-beta-D-glucopyranosyl (1 --> 6)-beta-D-glucopyranoside (3), 3-O-alpha-L-rhamnopyranosyl (1 --> 2)-alpha-L-arabinopyrano-syl-oleanolic acid-28-O-alpha-L-rhamnopyranosyl (1 -->4)-beta-D-glucopyranosyl (1 --> 6)-beta-D-glucopyranoside (4), 3-O-alpha-L-rhamnopyranosyl (1 --> 2)-beta-D-xylopyranosyl-oleanolic acid-28-O-alpha-L-rhamnopyranosyl (1 --> 4)-beta-D-glucopyranosyl (1 --> 6)-beta-D-glucopyranoside (5).


CONCLUSIONS
Compound 1 - 4 are isolated from this plant for the first time. Compound 1,2 are isolated from this genus for the first time.
