Optimization of Extraction Process of Volatile Oil from Aurantii Fructus and GC-MS Analysis of Its Chemical Constituents
Objective:To optimize extraction process of volatile oil from Aurantii Fructus,and analyze difference of chemical constituents in volatile oil from Aurantii Fructus with grinding degree of 24 mesh and 50 mesh.Method:Volatile oil from Aurantii Fructus was extracted by steam distillation,orthogonal test was adopted to optimize process of volatile oil.GC-MS was employed to compare similarities and differences between volatile oil from Aurantii Fructus with grinding degree of 24 mesh and 50 mesh.Result:Optimum extraction conditions of steam distillation were as follows:the comminution degree of 24 mesh,soaked 0.5 h and extracted 7 h with 11 times the amount of water.Forty-five components in volatile oil from Aurantii Fructus with grinding degree of 24 mesh were identified,there were 39 components for 50 mesh,accounting for 99.46％ and 99.53％ of total content of volatile oil,respectively.Conclusion:This optimized process is stable and feasible with high extraction rate of volatile oil.
