摘要:

     研究了用超临界CO2萃取法从白芷中提取欧前胡素和异欧前胡素,根据正交试验设计确定了超临界萃取最佳工艺条件为温度60 ℃、萃取压力25 MPa和药材粉碎度40~60目,并放大50倍进行萃取试验。利用高速逆流色谱技术分离纯化了欧前胡素和异欧前胡素,溶剂系统为正己烷:乙酸乙酯:甲醇:水(1:0.4:1.1:0.5,V/V)。采用HPLC-DAD,MS对欧前胡素和异欧前胡素进行了定性定量分析,得到产物纯度达99.0%以上,本方法简便快捷,重现性好。

Abstract:

     This paper addressed the extraction of imperatorin and isoimperatorin from Angelica dahurica (Fisch. ex- Hoffm.) with supercritical CO2 extraction method. Orthogonal experiments show that the optimal technological conditions of this extraction method are temperature of 60 ℃, pressure of 25 MPa , sample particle size of 40~60 mesh and 50 times amplification of a preparative supercritical fluid extraction (SFE) system. We separated and purified imperatorin and isoimperatorin with high-speed counter-current chromatography and a two-phase solvent system of 1:0.4:1.1:0.5 (n-hexane-ethyl vs. acetate vs. methanol vs. water, V/V). We also employed HPLC-DAD and MS to perform quantative and qualitive analysis for imperatorin and isoimperatorin.The purities of them were both above 99.0%.The method is convenient and fast,with a high reproducibility.

Key words: supercritical CO2 fluid extraction, HSCCC, imperatorin, isoimperatorin
