阿魏属挥发油成分及其分类学意义

利用ＧＣＭＳ计算机联用方法从我国阿魏属（ＦｅｒｕｌａＬ．）１５种１变种根部挥发油中分离鉴定出２１４种成分，其中广布成分有２２种。挥发油成分中８０％是萜类，其次是多硫化合物。萜类中主要有单萜和倍半萜两大类，均以环化结构成分为主。通过全成分和萜类成分的多种聚类分析，对样品进行归类，结合形态特征、核型、黄酮成分等已有资料以及地理分布，讨论了挥发油成分在阿魏属分类中的意义，同时对所分析种类进行了类群划分和调整

The chemical constituents of volatile oil from Ferula L. in China and its taxonomical significance\

Two hundred and fourteen chemical constituents of volatile oil from the roots of 15 species and 1 variety of Ferula L. in China were identified by GC MS Computer method. Among them 22 constituents are widespread, such as guaiol, myristicin and endo borneol. The main type of the constituents is terpenes which is composed of the monoterpenes and the sesquiterpenes. Cyclic structure is the major type in all terpenes. According to the hierarchical cluster analysis of the determinated constituents, as well as information of morphological character, karyotype and flavonoide, the studied species could be divided into several groups and the taxonomic position of some species should be adjusted.
