龙蒿挥发油成分研究

Studies on the chemical constituents of the essential oil of Artemisia dracunculus

目的:分析龙蒿的化学成分。方法:采用水蒸气蒸馏法提取,运用毛细管气相色谱 质谱联用法对龙蒿挥发性化学成分进行了分析,用气相色谱面积归一化法测定了各成分的相对百分含量。结果:经毛细管色谱分离出36个峰,并鉴定出峰所对应的化合物。其主要化学成分为3,7 -二甲基 1,3,7- 辛三烯(38. 4 3% ) ,1S α- 蒎烯(36. 96 % ) ,1- 甲氧基-4 (2- 丙烯基) 苯(8 5. 7% ) ,柠檬烯(6 . 33% ) ,1R -α- 蒎烯(3. 4 0 % )等。

Objective: To analyse the chemical constituents of Artemisia dracunculus. Method: The essential oil from A. dracunculus was extracted by steam distillation and the chemical constituents were analysed by capillary GC-MS method. The relative content of each component was calculated by area normalization. Result: 36 peaks were separated and all of them were identified. The main chemical components were 3,7-dimethyl-1,3,7-octatriene(38.43%), 1S-alpha-pinene(36.96%), 1-methoxy-4-(2-Propenyl)-benzene(8.57%), limonene(6.33%), 1R-alpha-pinene(3.40%),etc. Conclusion: The study provided solid and scientific proof for the further exploitation and utilization of A. dracunculus.
