维药香蜂花挥发油的GC-MS分析

结合气相色谱-质谱联用技术和保留指数对维医常用药材香蜂花挥发油提取物进行了分析.从该挥发油中共准确鉴定出28个化合物,占提取物总量的99.02％.结果发现,主要成分有(E)-3,7-dimethyl-2,6-octadien-1-ol acetate( 26.48％)、(Z)-citral(15.46％)、(E)-nerol(14.51％)、(E)-citral(14.43％)、isoanisole (7.88％)、palmitic acid (6.93％)和(Z)-nerol (2.56％),多为单萜和倍半萜类成分,为维药香蜂花的质量标准制定提供了科学依据.

Analysis of Essential Oil Components in Melissa officinalis Linn by GC-MS

The essential oil components were analyzed in Melissa officinalis Linn by both GC-MS and retention indices at the same time.Essential oil obtained by hydrodistillation from dried aerial part of M.officinalis Linn collected from Xinjiang province(western China),was analyzed by gas chromatography-flame ionization detector(GC-FID),gas chromatography coupled to mass spectrometry(GC-MS) and all components’ retention indices.Twenty-eight constituents were accurately detected from the essential oil,accounting for 99.02% of the total amount.The quantitatively significant constituents of the essential oil were(E)-3,7-dimethyl-2,6-octadien-1-ol acetate(26.48%),(Z)-citral(15.46%),(E)-nerol(14.51%),(E)-citral(14.43%),isoanisole(7.88%),palmitic acid(6.93%) and(Z)-nerol(2.56%).The components of M.officinalis Linn essential oil were complicated and were dominated by mono-and sesquiterpene compounds,which were maybe the main biological activities.
