Two new 9,19-cycloartenol glycosides from the roots of Cimicifuga simplex Wormsk

- Two new cycloartenol triterpene saponins were isolated from Cimicifuga simplex Wormsk.
- Their structures were established by detailed spectroscopic analysis, including extensive 2D NMR data.
- This is the first time to report 16,17-double bond type glycosidesaponin from Cimicifuga species.
- Their immunosuppressive activities were also carried out by ConA-stimulated T splenocyte proliferation assay in vitro.
