目的:分析湘西产黄花蒿挥发性化学成分。方法:采用超临界CO2流体方法萃取挥发性物质,以气相色谱-质谱联用技术结合计算机检索进行化学成分分离和鉴定,用色谱峰面积归一化法计算各组分的相对百分含量。结果:分离鉴定出95种化合物(占挥发油总量的93.09%),含量在6%以上的有杜松醇(12.75%)、脱氧青蒿素(10.78%)和1H-环丙烷萘(7.10%)、1,3-二氧杂环己烷-4,6-二酮(6.19%)、α-愈创木烯(6.06%)、二环[2.2.1]庚醛-2酮(6.03%)等。结论:黄花蒿中3-甲基十八碳烯酸、苯甲基异丁基酮、喇叭茶醇、4-(2,6,6-三甲基环己烯基-1-基)-丁酸等47种化合物过去未见报道。
Objective: To analyze the volatile chemical constituents of Artemisia annua L. in Xiangxi. Methods: The volatile compounds were extracted by supercritical CO2 fluid extraction. The chemical constituents were separated and identified by gas chromatography-mass spectrometry (GC-MS) combined with computer search. The relative percentages of each component were calculated by the normalization of chromatographic peak area. Results: 95 compounds (accounting for 93.09% of the total volatile oil) were isolated and identified. Among these compounds were Juniperin (12.75%), deoxyartemisinin (10.78%) and 1H-cyclopropanenaphthalene (7.10% ), 1,3-dioxane-4,6-dione (6.19%), α-guaraccone (6.06%), bicyclo [2.2.1] )Wait. Conclusion: 3-methyloctadecenoic acid, benzyl isobutyl ketone, honcholar alcohol, 4- (2,6,6-trimethylcyclohexenyl-1-yl) -butyl 47 compounds such as acid have not been reported in the past.
