Popis:	Three saponins were isolated from leaves of Ilex chamaedryfolia. Their structures were established 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-oic acid 28-O-β-D-glucopyranosyl-(1-3)-β-D-glucopyranosyl ester, the new saponin 3β-O-β-D-glucopyranosyl-(1-3)-α-L-arabinopyranosyl-20( S)-19α-hydroxyurs-12-en-28-oic acid 28-O-β-D-glucopyranosyl ester and the known saponin 3β-O-β-D-glucuronopyranosyl-20(R )-19α-hydroxyurs-12-en-28-oic acid 28-O-β-D-glucopyranosyl ester. Ursolic acid and α-amyrin were also isolated.
