A new triterpene saponin, ilexoside P (1), along with three known triterpene saponins, ilexoside O (2), ilexsaponin B3 (3) and ilexpublesnin A (4) was isolated from the roots of Ilex pubescens. Their chemical structures were elucidated on the basis of UV, IR, MS, and NMR spectroscopic analyses coupled with chemical degradation. In addition, the xanthine oxidase (XOD) inhibitory activity of the isolated
从毛冬青的根中分离出一种新的三萜皂苷,冬凌草甙P(1),以及三个已知的三萜皂甙,冬凌草甙O(2),冬凌草皂苷B 3(3)和冬凌草甲素A(4)。在紫外,红外,质谱和核磁共振光谱分析以及化学降解的基础上阐明了它们的化学结构。此外,还报告了分离出的皂苷的黄嘌呤氧化酶(XOD)抑制活性。化合物1在测试中表现出弱的XOD抑制活性。
