[Study on triterpenoid saponins in the rhizome of Anemone hofengensis].
OBJECTIVE
To study the triterpenoid saponins in the rhizome of Anemone hofengensis.


METHODS
The constituents were separated with various chromatographic techniques and their structures were elucidated by physicochemical properties and spectral data.


RESULTS
Five compounds were isolated and identified as 3-O-alpha-L-rhamnopyranosyl-(1 --> 2)-alpha-L-arabino-pyranosyl-oleanolic acid (1), 3-O-alpha-L-rhamnopyranosyl-(1 --> 2)-beta-D-glucopyranosyl-(1 --> 2)-alpha-L-rhamnopyranosyl-oleanolic acid 28-O-alpha-L-rhamnopyranosyl-(1 --> 4) -beta-D-glucopyranosyl-(1 --> 6)-beta-D-glucopyranoside (2), 3-O-alpha-L-rhamnopyranosyl-(1 --> 2) [beta-D-glucopyranosyl-(1 --> 4)]-alpha-L-rhamnopyranosyl-oleanolic acid-28-O-beta-D-glucopyranosyl-(1 --> 6)-beta-D-gluco-pyranoside (3), 3-O-beta-D-glucopyranosyl-(1 --> 2)-beta-D-xylopyranosyl-oleanolic acid 28-O-beta-D-glucopyranosyl-(1 --> 6)-beta-D-glucopyranoside (4), oleanolic acid-28-O-alpha-L-rhamnopyra-nosyl-(1 --> 4)-beta-D-glucopyranosyl-(1 --> 6)-beta-D-glucopyranoside (5).


CONCLUSIONS
Compound 1 - 5 are isolated from this plant for the first time.
