摘要
为了明确葫芦巴浸膏中挥发性成分组成、含量及不同萃取方式对葫芦巴浸膏挥发性成分萃取效果的影响,分别采用固相微萃取(SPME)、溶剂萃取(LLE)和同时蒸馏萃取(SDE)对葫芦巴浸膏中挥发性成分进行提取,利用GC-MS技术对挥发性成分进行分析鉴定。3种萃取方法共鉴定出160种挥发性成分,其中固相微萃取(SPME)37种、溶剂萃取(LLE)66种、同时蒸馏萃取(SDE)113种,3种方式共有的16种,具有葫芦巴浸膏特征香味成分的葫芦巴内酯3种方式均能萃取出来,比较3种萃取方法可知:同时蒸馏萃取(SDE)和溶剂萃取(LLE)对葫芦巴浸膏中香味物质提取的更为全面,两种萃取方式共鉴定出151种。
In order to clarify the composition and content of volatile components in the fenugreek extract and the effect of different extraction methods on the extraction of volatile components of fenugreek extract,the volatile components in the fenugreek extract were extracted by solid phase microextraction(SPME),solvent extraction(LLE) and simultaneous distillation extraction(SDE),and the volatile components were analyzed and identified by GC-MS.A total of 160 volatile components were identified by three extraction methods,including 37 solid phase microextraction(SPME),66 solvent extraction(LLE),and 113 kinds of simultaneous distillation(SDE).The fenugreek lactone characteristic of the fenugreek extract can be extracted in three ways.Comparing the three extraction methods,it can be known that the simultaneous extraction(SDE) and solvent extraction(LLE) extract the aroma from the fenugreek extract more comprehensive,and a total of 151 species were identified by two extraction methods.
