[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).
Conclusion:
Compound 1 - 5 are isolated from this plant for the first time.
