柽柳花挥发性成分研究

Studies on the Volatile Component from the Flower of Tamarix chinensis

目的:定性分析柽柳花中的挥发性成分。方法:采用固相微萃取技术提取柽柳花的挥发性成分,采用气相色谱-质谱联用技术结合保留指数法鉴定其成分。结果:从柽柳花的挥发油中共鉴定出36个化合物,其中含量最高的是十五烷(9.80%),其次为6,10,14-三甲基-2-十五烷酮(7.61%)、5,6-二氢-6-戊基-2H-吡喃-2-酮(6.83%)、十六烷(6.25%)和二氢猕猴桃内酯(5.13%)。结论:本研究可为进一步开发利用柽柳资源提供科学依据。

OBJECTIVE：To conduct a quantitative analysis on the volatile constituents from the flower of Tamarix chinensis. METHODS：The volatile constituents were extracted from the flower of T. chinensis by solid-phase microextraction technique and component identification was carried out by GC-MS combined with retention index. RESULTS：36 kinds of compounds were identified,among which pentadecane took up a greatest proportion （9.80%）,followed by 6,10,14-trimethyl-2-pentadecanone （7.61%）,5,6-dihydro-6-pentyl-2H-pyran-2-one（6.83%）,hexadecane（6.25%）and 5,6,7,7a-tetrahydro-4,4,7a-trimethyl-2（4H）-benzofuranone（5.13%）.CONCLUSION：This study serves as a scientific basis for the further development and utilization of T. chinensis.
