摘　　要：目的:比较水蒸气蒸馏及CO2超临界萃取对香薷挥发油提取的影响。方法:高效液相色谱法测定百里香酚和香芹酚的含量,比较理化性质。结果:虽然CO2超临界萃取提取的挥发油总量较高,但杂质也较多,含有大量的脂肪油,不利于储藏。水蒸气蒸馏法提取香薷挥发油,百里香酚、香芹酚含量高于CO2超临界萃取法的3倍。结论:水蒸汽蒸馏法提取的香薷挥发油明显优于CO2超临界卒取。Objective:To compare with the influence of the essential oils of Mosla chinensis extracted by Supercritical-CO_2 Fluid Extraction(SCFE) and by steam distillation(SD).Methods:To develop the HPLC method for determination of Thymol and Carvacrol,and compare the physico-chemical property.Result:Although the total amount of essential oils which extracted by SCFE is higher relatively,it has more impurity and fat oils,so it is not good for storing.The Thymol and Carvacrol content of the essential oils of Mosla chinensis extracted by SD was three times that of SCFE.
