摘要
应用气相色谱-质谱联用技术对高要产广藿香茎和叶中挥发油成分进行了分析,从茎油中分离出107个色谱峰,鉴定了52个化合物,占总量的78.83％;从叶油中分离出50个色谱峰,鉴定了36个化合物,占总量的96.95％。茎和叶油中主要含广藿香酮(分别为30.99％和21.31％)、广藿香醇(10.26％和37.53％)反式-丁香烯(4.92％和6.75％)、α-愈创木稀(2.27％和6.18％)、反式,反式-法呢醛(2.04％和1.40％)、α-广藿香烯(1.13％和2.71％)、刺蕊草烯(1.56％和1.99％)等。茎与叶挥发油中亦存在一些差异:茎中有27个成分是叶中没有或含量极微而未能检出,叶中亦有11个成分是茎中不具有的。
The chemical constituents of the volatile oil of the stems and leaves of Pogostemon cablin collected from Gaoyao county,Guangdong province, have been studied by means of GC-MS. Sixty four compounds have been identified. The main constituents are pogostone (30.99% in stems,21.31% in leaves, the same below), patchouli alcohol (10.26% , 37.53%), trans-caryophyllene (4.92% ,6.75%), α-guaiene (2.27% ,6.18%) and seychellene (1.56% ,1.99%),etc.
