Isolation and identification of two new sargentodoxosides from and their agonistic effects against FXR.

(Oliv.) Rehd. et Wils is a traditional Chinese medicine to treat acute appendicitis, rheumarthritis, abdominal pain, and painful menstruation for a long history. The investigation of led to the isolation and identification of twenty-three secondary metabolites, including two new compounds, sargentodoxosides A () and B (), and twenty-one known ones (). Their structural characterization was conducted by HRESIMS, 1 D and 2 D NMR spectra. All the isolated compounds were assayed for their agonistic activities against the farnesoid X receptor (FXR). Nine of the isolated compounds displayed significant agonistic effects against FXR at 0.1 µM, suggesting that they could be served as potential agents for the development of FXR agonists.
