摘要
采用吹扫捕集技术对紫苏不同变种叶片中的挥发性成分进行富集,以气质联用仪(GC-MS)进行鉴定,运用面积归一化法确定各组分的相对含量。结果表明,分别属于紫苏属植物3个变种的4份试材之间叶片挥发油的组分和相对含量差异显著。4份紫苏试材共检测出31种挥发油成分,但其共有的成分仅有顺-3-己烯醛、石竹烯和圣亚麻三烯3种。野生紫苏变种的主要成分是柠檬烯(77.90%)、石竹烯(14.33%)、顺-3-己烯醛(4.9%)、胡椒酮(1.71%),回回苏变种的主要成分是石竹烯(30.65%)、柠檬烯(24.60%)、顺-3-己烯醛(21.82%)、紫苏醛(17.70%),紫苏变种1(来源于河北安国市)的主要成分是5-乙叉-1-甲基-环庚烯(52.79%)、顺-3-己烯醛(19.98%)、石竹烯(13.60%)、紫苏醛(9.46%),紫苏变种2(来源于广西灵山县)的主要成分是紫苏醛(31.86%)、5-乙叉-1-甲基-环庚烯(31.68%)、顺-3-己烯醛(21.50%)、石竹烯(10.47%)。
Purge and trap technique was used for enriching the volatile components of the leaves of different variants of Perilla L.prior to GC-MS analysis.Area normalization method was employed for the subsequent quantification.The results showed that there were significant differences in type and relative contents of volatile components among 4 samples belonging to 3 variants of Perilla L..Totally 31 volatile components were identified in the samples,3 of which,namely [Z]3-hexenal,caryophyllene and santolina triene were contained in all of the samples.The main components of the leaves of wild growing P.frutescens（Linn.） Britt.var.acuta（Thunb.） Kudo included limonene（77.90%）,caryophyllene（14.33%）,[Z]-3-hexenal（4.9%）,and 3-methyl-6-[1-methethyl]-2-cyclohexen-1-one（1.71%）,those of the leaves of P.frutescens（Linn.） Britt.var.crispa（Benth.）H.W.Li caryophyllene（30.65%）,limonene（24.60%）,[Z]-3-hexenal（21.82%） and perilla aldehyde（17.70%）,and those of the sample No.1 of P.frutescens（Linn.）Britt.var.frutescen from Anguo,Hebei province 5-ethylidene-1-methyl-cycloheptene（52.79%）,[Z]-3-hexenal（19.98%）,caryophyllene（13.60%） and perilla aldehyde（9.46%）,and those of the sample No.2 of P.frutescens（Linn.）Britt.var.frutescen from Linshan,Guangxi autonomous region perilla aldehyde（31.86%）,5-ethylidene-1-methyl-cycloheptene（31.68%）,[Z]-3-hexenal（21.50%） and caryophyllene（10.47%）.
