摘要
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.
