摘要
文章对花椒油乙醇提取工艺参数进行优化,并对水提和醇提花椒油进行成分分析比较。利用正交实验法,以花椒油提取率为考察指标,对试剂浓度、提取温度、提取时间进行研究,并利用气相色谱-质谱联用仪对醇提和水提的花椒油进行成分分析。经实验选择最佳提取工艺条件为乙醇浓度为95%,提取温度为50℃,提取时间5 h,最高提取率12.33%;通过分析,醇提花椒油含量高成分简单,水提花椒油含量低成分复杂,两者成分相差较大。花椒油提取率比优化前有很大提高,水提醇提花椒油成分差异大。
The alcohol extraction process of zanthoxylum oil was optimized,at the same time,the constituents of zanthoxylum oil which extracted by water extraction and alcohol extraction was analyzed and compared.Using orthogonal experimental method,with zanthoxylum oil extraction rate of the indexes,the extraction reagent,reagent concentration,extraction temperature,extraction time were studied,and using GC-MS to analysis the composition of zanthoxylum oil extracted by alcohol extraction and water extraction.The potimal operation conditions of extracting zanthoxylum oil were as the following： ethanol concentration of 95%,50 ℃ of extraction temperature,5 h of extraction time,the maximum extraction rate is 12.33%;By analysis,large difference in composition by ethanol extract and water,and the content of simple components is high in zanthoxylum oil by ethanol,the content of complex components is low in zanthoxylum oil by water.
