钻叶龙胆挥发油化学成分的GC-MS分析

目的:研究钻叶龙胆挥发油化学成分的组成.方法:采用水蒸气蒸馏法提取钻叶龙胆的挥发油,以气相色谱-质谱(GC/MS)联用技术测定其成分.结果:从钻叶龙胆挥发油中鉴定出18种成分,占挥发油的98.4％,主要成分为棕榈酸(28.05％)、15-冠醚-5(14.29％)、二十二烷(10.19％)、二十九烷(6.82％)、3,7,11,15-四甲基-2-十六烯(6.25％)、肉豆蔻酸(5.96％)、二十四烷(5.46％)、叶绿醇(4.84％)等.结论:钻叶龙胆挥发油成分中含有多种具有明显生物活性的成分,为其进一步的开发利用提供了科学依据.

Chemical Compounds in Volatile Oils of Gentiana haynaldii by GC-MS

Objective:To analyze the chemical constituents in the volatile oils of Gentiana haynaldii Kanitz. Method: The volatile oils of Gentiana haynaldii were extracted by water steam distillation and its chemical constituents were separated and identified by GC-MS. Result: Eighteen components were identified, which constituted about 98.4% of the total volatile oils. The main compounds were hexadecanoic acid (28.05%),15-crown-5(14.29%),n-docosane(10.19%),n-nonacosane(6.82%),3,7,11,15-tetramethyl-2-hexadecene (6.25%),tetradecanoic acid(5.96%),n-tetracosane(5.46%),(E)-3,7,11,15-tetramethyl-2-hexadedcen-1-ol(4.84%). Conclusion: Many components in the volatile oils had obvious biological activity, and this research provided a scientific evidence for deep exploitation and usage of G. haynaldii.
