【Abstract】 As a result of the continueing studies on chemical constituents of Ilex pubescons, four saponins were isolated from butanol fraction of ethanol extracts. Three of them were identified as Ilexolide A, Ilexsaponin B and Pedunculoslde respectively. Another is a new saponin. The structure of which was elucidated as 3β-O-D-Xylopyranosyl Ilexolide B from spectral analysis.更多还原
