闪式提取法辅助肉豆蔻挥发油提取工艺研究及GC-MS成分分析OACSTPCD

Objective To establish a flash extraction method for extraction of Nutmeg volatile oil,and compare with the chemical composition of the volatile oil extracted by steam distillation.Methods The optimum process for extracting volatile oil was determined by flash extraction method by orthogonal test,and through the Nutmeg volatile oil extraction rate and GC-MS analysis,to determine the feasibility of flash extraction method.Results The best extraction process of flash extraction method was flash voltage 105 V,flash pretreatment 60 s,liquid material ratio 10 : 1,distillation 4 h,the extraction rate of volatile oil was 6.23％;Both the flash extraction method and the steam distillation can separate 52 peaks,steam distillation can identify 42 components,and the flash extraction method can identify 41 components,compared with the steam distil-lation,flash extraction method added 6 kinds of ingredients,and 7 kinds of ingredients were not detected,and there were 35 kinds of ingredients in both.Conclusion The flash extraction method is simple to operate,feasible and repeatable,and can be used as a method to extract Nutmeg volatile oil.
