Abstract

Ten triterpene saponins have been isolated from a MeOH extract of the leaves of Ilex oblonga. In their structures, six new triterpenoid saponins were named as oblonganosides H-M (2, 4, 5, and 8-10). All structures were elucidated on the basis of spectroscopic analysis. Among the triterpenoid saponins, three compounds (7, 8, and 10) showed obvious activities in inhibiting multiplication of the tobacco mosaic virus (TMV).

摘要

从长圆叶冬青叶的甲醇提取物中分离出了十种三萜皂苷。在其结构中，六种新的三萜皂苷被命名为长圆叶冬青苷H - M（2、4、5和8 - 10）。所有结构均通过光谱分析得以阐明。在这些三萜皂苷中，三种化合物（7、8和10）在抑制烟草花叶病毒（TMV）增殖方面表现出明显活性。
