Fund Project: The authors are grateful to Professor Yin-Suo Zhou, School of Pharmacy, Lanzhou University, for the plant identification, and to the National Laboratory of Applied Organic Chemistry and Analytic Center, Lanzhou University for measuring ¹H, ¹³C NMR spectra and FAB-MS, HR-FABMS, EI-MS, respectively. This work was supported by the Education Bureau of Fujian Province (No.JS06025) and National Natural Sciences Foundation of China (No.29772010).

Two new triterpenoid saponins were isolated from the roots of Rhaponticum uniflorum. Their structures were elucidated as 3-O-[β-D-glucopyranosyl]-ilexolic acid-28-O-[β-D-glucopyranosyl] ester 1 and 3-O-[β-D-glucopyranosyl]-urs-12, 19 (29)-dien-oic acid-28-O-[β-D-glucopyranosyl] ester 2 mainly by 1D, 2D NMR techniques and chemical methods.
- Rhaponticum uniflorum,
- Compositae,
- Triterpenoid saponin
