安徽产艾叶挥发油成分GC-MS分析

摘要

Objective:To determine the primary chemical component of volatile oil from Artemisia argyi growing Anhui province.Methods:The volatile oil was extracted by supercritical CO2 extraction technique,and its primary chemical component was measured with gas chromatography-mass spectrometer (GC-MS).The relative oil percentage in the Artemisia argyi was calculated by area normalization method.Results:A total of 48 chemical components was isolated from the volatile oil,in which artemisol content was the highest (10.26％),followed by oleic acid amide (6.51％),cyclohexanone (5.07％),13-docosenamide,(Z)-(4.73％),heptacosane (3.65 ％),phytol (3.61％),hexadecanamide (3.38％),bicyclo [3.1.1] hept-2-en-6-one,2,7,7-trimethyl-(2.56％),and O-cymene(2.21％).Ketone and alcohol were in major proportion.Conclusion:The chemical components in the volatile oil from Artemisia argyi growing in Anhui province are different from the species in other origins.%目的:分析安徽产艾叶挥发油的主要化学成分.方法:采用超临界CO2法从安徽产艾叶中提取挥发油,用气相色谱-质谱联用(GC-MS)法对其化学成分进行鉴定,用面积归一化法计算各组分的相对百分含量.结果:共分离出48个化学组分,所占比例最高的为蒿醇(10.26％),其次为油酸酰胺(6.51％)、环己酮(5.07％)、(Z)-13-二十二烯酰胺(4.73％)、正二十七烷(3.65％)、植醇(3.61％)、棕榈酰胺(3.38％)、2,7,7三甲基二环[3,1,1]庚-2-烯-6-酮(2.56％)、邻-异丙基苯(2.21％)等,以酮类和醇类居多.结论:安徽产艾叶挥发油成分与其他产地艾叶挥发油成分不完全相同.
