不同产地生姜精油化学组分比较与分析

The comparation and analysis of essential oil components of Zingiber officinale from different regions

该文采用水蒸气蒸馏法对6个不同产地生姜的精油进行提取,并利用气相色谱-质谱联用技术测定其化学组分并进行比较。结果表明,6个不同产地生姜精油的提取率分别为湖南汝城0.98%、江西吉安1.05%、四川眉山1.08%、山东昌邑0.73%、福建长汀1.13%、云南红河1.27%;分别鉴定出28、28、28、27、29、28种化合物,各占精油总相对百分含量的98.50%、98.14%、98.05%、96.17%、99.03%、97.12%;它们的共有成分有15种,特有成分湖南汝城2种、江西吉安1种、山东昌邑4种、福建长汀1种,而四川眉山和云南红河尚未检测到特有成分。

To investigate the chemical components of essential oil from six different regions of Zingiber officinale,and to compare their differences,the essential oil was extracted from the steam distillation method.The components were identified by GC-MS,and the relative contents of each component was compared by peak area normalization.The results showed that the contents of essential oil from Zingiber officinale of Rucheng Hunan,Ji′an Jiangxi,Meishan Sichuan,Changyi Shangdong,Changting Fujian and Honghe Yunnan were 0.98%,1.05%,1.08%,0.73%,1.13%and 1.27%,respectively.Among them,28,28,28,27,29,28 compounds were identified,which accounted for 98.50%,98.14%,98.05%,96.17%,99.03%and 97.12%,respectively.There were 15 kinds of components were shared in all samples,and the unique ones presented in Rucheng Hunan,Ji'an Jiangxi,Changyi Shandong,Changting Fujian were 2,1,4,1.However,Meishan Sichuan and Honghe Yunnan were not.
