【 摘 要 】

Three saponinswere isolated from leaves of Ilex chamaedryfolia. Their structures wereestablished by spectroscopic and mass spectrometry data as the new saponin 3β-O-β-D-glucopyranosyl-(1-3)-α-L-arabinopyranosyl-20(S)-19α-hydroxyurs-12-en-28-oicacid 28-O-β-D-glucopyranosyl-(1-3)-β-D-glucopyranosylester, the new saponin 3β-O-β-D-glucopyranosyl-(1-3)-α-L-arabinopyranosyl-20(S)-19α-hydroxyurs-12-en-28-oicacid 28-O-β-D-glucopyranosylester and the known saponin 3β-O-β-D-glucuronopyranosyl-20(R)-19α-hydroxyurs-12-en-28-oicacid 28-O-β-D-glucopyranosylester. Ursolic acid and α-amyrinwere also isolated.
