多枝柽柳挥发性成分分析

Study on Volatile Constituents from Tamarix ramosissima

目的:定性分析多枝柽柳的挥发性成分。方法:采用固相微萃取技术提取多枝柽柳的挥发性成分,采用气相色谱-质谱联用结合保留指数法鉴定。结果:共分离出34个成分,鉴定了其中的25个,用峰面积归一化法测定了其相对质量分数,占挥发性成分总峰面积的89.50%。其主要成分是十五烷(16.83%)、壬醛(12.45%)、十六烷(8.20%)、十四烷(8.08%)和己醛(7.37%)。多枝柽柳挥发性成分主要含有烃、醛、酮和醇4类化合物,其中烃类的含量最高,为37.11%;其后依次为醛类(占27.56%)、酮类(占8.89%)、醇类(8.04%)。结论:本研究可为进一步开发利用红柳资源提供科学依据。

OBJECTIVE： To conduct a quantitative analysis of volatile constituents from Tamarix ramosissima.METHODS： The volatile constituents were extracted from T.ramosissima using solid phase microextraction and identified using GC-MS combined with Kvotas retention index.RESULTS： 34 constituents were separated from T.ramosissima and 25 constituents were identified.The relative mass content of volatile constituents was determined by peak area normalization method,accounting for 89.50% of total peak area.The main chemical constituents were pentadecane （16.83%）,nonanal （12.45%）,hexadecane （8.20%）,tetradecane （8.08%） and hexanal （7.37%）.The result showed hydrocarbon （37.11%）,aldehyde （27.56%）,ketone （8.89%） and alcohol （8.04%） were the main constituents.CONCLUSION： The study can provide scientific basis for the further development of T.ramosissima.
