摘要
[目的]通过对山苍子挥发油和商品油的气相色谱-质谱(GC-MS)测定,对湖南省怀化地区产山苍子挥发油进行品质评价.[方法]建立了山苍子挥发油的GC-MS分析检测方法,通过NIST标准谱库检索进行定性分析.[结果]从山苍子挥发油中共检出29种挥发性成分,按峰面积归一化法对占总峰面积90％的挥发性成分进行定性分析,结合文献发现山苍子挥发油中的主要成分为α-柠檬醛、β-柠檬醛和D-柠檬烯,3种成分所占比例达65.95％,其次为β-月桂烯、芳樟醇、石竹烯、α-蒎烯和香茅醛等.商品油与挥发油的化学组成基本一致,差异主要在低含量和低沸点组分,提示不同生产工艺会对产品组成产生影响.[结论]该研究为湖南怀化产山苍子的资源状况评估以及山苍子油的质量评价提供依据.
Abstract
[Objective] To evaluate quality of essential oil in Listea cubeba from Huaihua District of Hunan Province by GC-MS.[Method]GC-MS method for evaluating quality of essential oil in Listea cubeba was established,qualitative analysis was conducted by NIST standard library searching.[Result] There were 29 volatile components in Listea cubeba essential oil,and by means of the area normalization,the components accounting for 90％ of the sum of the total peak areas were assigned to the probable compound in the NTST library and the literature.The main volatile substances were α-citral,β-citral and D-limonene,which were the 65.95％ of the sum peak areas,followed by β-myrcene,linalool,caryophyllene,α-pinene,citronellal and so on.The practical volatile oil had the similar chromatogram to that of the oil from laboratory,and the difference between them was in low content and low boiling point components,indicating the quality of oil was affected by the production process.[Conclusion] The results can provide basis for evaluating Listea cubeba resource and quality of its essential oil in Huaihua District of Hunan Province.
