摘　　要：为探究干燥方式对藿香挥发性物质的影响,实验采用真空冷冻干燥(A)、微波干燥(B)、热风干燥(C)、自然风干(D)4种方式干燥藿香叶,以鲜藿香叶为参照品(E),利用GC-MS分析其挥发性物质,并结合维恩图分析其挥发性物质。实验结果表明:5个样品共检测到94种挥发性物质,共有物质11种,分别是苯甲醛、乙酸辛烯酯、异薄荷酮、(-)-薄荷酮、茴香脑、草蒿脑、D-柠檬烯、β-波旁烯、β-石竹烯、δ-荜橙茄烯、愈创奥。5个样品有效挥发性物质相对百分含量分别为97.543%、97.339%、97.851%、98.371%、96.967%。茴香脑为主要挥发性物质,四川自贡的藿香属于茴香脑化学生态型。干燥方式不会影响藿香主要挥发性物质。In order to explore the effect of drying methods on the volatile compounds of Agastache rugosa,the four methods such as vacuum freeze drying(A),microwave drying(B),hot air drying(C)and natural air drying(D)are used to dry Agastache rugosa leaves.Fresh Agastache rugosa leaves are used as the reference substance(E),and their volatile substances are analyzed by GC-MS and Venn diagram.The results show that a total of 94 kinds of volatile compounds with 11 common substances are detected in the 5 samples,which are benzaldehyde,octenyl acetate,isomenthone,(-)-menthone,anethole,estragole,D-limonene,β-bourbonene,β-caryophyllene,δ-cadinene,1,4-dimethyl-7-isopropylazulene.The relative percentage content of effective volatile compounds is 97.543%,97.339%,97.851%,98.371%and 96.967%respectively.Anethole is the main volatile compound,and Agastache rugosa in Zigong City,Sichuan Province belongs to anethole chemical ecotype.Drying methods will not affect the main volatile substances of Agastache rugosa.
