3个不同罗勒种叶中香气成分的GC-MS分析

摘要

The aroma components of three basils (Ocimum basilicum, Ocimum tashiroi Hayata, Ocimum gratissimum)were analyzed by GC/MS technology. The results showed that there were differences in both aroma kinds and relative contents among the three basils. There were 37 kinds of aroma components in Ocimum basilicum, and the relative content was 91.15%. 21 kinds of aroma components in Ocimum tashiroi Hayata and the relative content was 95.08%. 29 kinds of aroma components in Ocimum gratissimum and the relative content was 89.49%. The major compounds of aroma were alcohol and hydrocarbons, their total relative contents were 84.39%、 78.61% and 77.88% in the three cultivars respectively. The three basils shared one major aroma component, Bicycloheptane, 6, 6-dimethyl-2-methylene-, (1S)of. Eucalyptol, Benzene, 1-methoxy-4-(1-propenyl)-and Cyclofenchene were the proper major aroma components of Ocimum basilicum, Ocimum tashiroi Hayata and Ocimum gratissimum, respectively.%利用 GC/MS 技术分析罗勒(Ocimum basilicum L.)、台湾罗勒(Ocimum tashiroi Hayata)和丁香罗勒(Ocimum gratissimum)成龄叶的香气成分。结果表明：3个罗勒品种的叶片中香气成分的种类和含量存在明显差异：罗勒中检出37种香气物质，占其总挥发性物质的91.15%；台湾罗勒中检出21种香气物质，占95.08%；丁香罗勒中有29种，占89.49%。其中，烃类和醇类2类化合物在3种罗勒叶片中分别占挥发物总量的84.39%、78.61%和77.88%。β-蒎烯是3种罗勒共有的主要香气成分，桉树脑、茴香脑和环葑烯则分别是罗勒、台湾罗勒和丁香罗勒的主要香气成分。
