【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%)。更多还原

【Abstract】 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%).更多还原
