毛山蒟挥发油化学成分研究

Studies on the Chemical Components of Volatile Oil from Leaves of Piper martini C.DC.

目的:研究毛山蒟的化学成分,为毛山蒟植物的开发利用提供科学依据。方法:水蒸气蒸馏法提取毛山蒟叶中挥发油,GC-MS法分离鉴定其化学成分,并测定各化合物在挥发油中的相对百分含量。结果:共鉴定了43个成分,占挥发油的89%以上。结论:毛山蒟挥发油成分主要为萜类的衍生物,占挥发油的71.24%,其中双环杜鹃烯的含量最高达22.42%。

Objective： To study chemical components of volatile oil from leaves of Piper martini C. DC. and provide basis for the usage of Piper martini C. DC. Methods： The volatile oil was extracted from leaves of Piper martini C. DC. by steam distillation ; Its chemical components as well as their contents were analyzed by GC -MS. Results： 43 components were separated and identified, which account for over 89% of total volatile oil. Conclusions： The main chemical components of leaves of Piper martini C. DC. are derivates from terpene （71.24%）, with bicyclogermacrene as the highest （22.42%）.
