The GC-MS Method Determination the Content of the Characteristic Component α-farnesene in the Fufang Xianzhuli Ye and Study the Ginger Extraction Process
Objective To establish a GC-MS quantitative method for the characteristic constituent α-farnesene of ginger,and study the ginger extraction process in fufang xianzhuli ye.Methods In this experiment,the volatile components of fufang xianzhuli ye and ginger volatile oil solution were compared and analyzed by GC-MS,and the characteristic components α-terpineol and α-farnesene of ginger were found.Established a GC-MS method to determine the contents of α-farnesene in fufang xianzhuli ye and studed the contents and transfer rates of α-farnesen in ginger with different production processes.Results The fufang xianzhuli ye and ginger volatile oil solution identified 24 and 20 volatile components,respectively.The results of the GC-MS method showed that the exclusivity,linearity,precision,stability and repeatability of the method were good,and the recovery rate met the requirements.By measuring the contents of α-farnesene in ginger with different production processes,it was found that the extraction process of the juice was very important for the retention of volatile components in ginger.Conclusion This method is stable and reliable,and can provide experimental basis for optimizing the preparation process of ginger in fufang xianzhuli ye.
