摘　　要：Two new triterpenoid saponins were isolated from the roots ofRhaponticum 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-b-glucopyranosyl] ester 2 mainly by 1D, 2D NMR techniques and chemical methods.Two new triterpenoid saponins were isolated from the roots ofRhaponticum uniflorum.
