摘要
[目的]研究枇杷叶挥发油化学成分。[方法]用水蒸气蒸馏法得到挥发油,运用GC-MS技术,结合计算机检索对其具体化学成分进行分析和鉴定,用峰面积归一化法计算各个组分的相对含量。[结果]已经鉴定组分共47个,占流出组分总量的86.33%。含量较高的组分有β-倍半水芹烯(4.14%)、异桉叶油(5.07%)、环己酮(5.25%)、顺-3-己烯-1-醇(5.30%)、香叶烯D(5.35%)、10,10-二甲基-2,6二(亚甲基)-双环[7.2.0]十一烷(7.95%)、水杨酸甲酯(11.72%)等。[结论]GC-MS法分析、鉴定枇杷叶挥发油化学成分,技术简单易行,操作简便,为枇杷叶的深入开发提供了基础科学信息。
[Objective]The aim was to study the components of volatile oil from leaves of Eriobotrya japonica（Thunb.） Lindl.[Method]The essential oil was obtained by steam distillation.According to GC-MS technology,and combining with computer retrieval,the specific chemical composition was separated and identified.The relative content of each component was determined by peak area normalization.[Result]Forty-seven volatile compounds were isolated and identified,which accounted for 86.33% of the total oil.The main compounds with higher contents were as follows： β-sesquiphellandrene（4.14%）,iso-eucalyptus oil（5.07%）,cyclohexanone（5.25%）,cis-3-hexene-1-alcohol（5.30%）,Myrcene D（5.35%）,10,10-dimethyl-2,6-bi（methylene）-bicyclo undecane（7.95%）,salicylic acid methyl ester（11.72%）and so on.[Conclusion]GC-MS analysis was used to identify the chemical components of volatile oil from leaves of Eriobotrya japonica（Thunb.） Lindl,which had the characteristics as follows： easily operative technology and easy and simple to handle,all those provided the basic science information for the deep development of the leaves of Eriobotrya japonica（Thunb.） Lindl.
