摘要:

建立通过高速逆流色谱从北五味子中快速分离科罗索酸的方法。将北五味子的乙醇提取物经AB-8大孔树 脂初步纯化后直接采用高速逆流色谱进行分离,并通过高效液相色谱法考察了粗提物在不同溶剂体系中的分配情 况。结果表明,最佳溶剂体系为正己烷-乙酸乙酯-甲醇-水(6∶5∶5∶4,V/V),从150 mg粗提物中一次性分离制备得 到6.3 mg纯度为97.6%的科罗索酸。该方法分离效率较高,对科罗索酸在食品医药领域的应用具有重要意义。

Abstract:

An effective and rapid method for the separation of corosolic acid from Schizandra chinensis (Turcz.) Baill by high-speed counter-current chromatography (HSCCC) was established.The alcohol extract of Schizandra chinensis (Turcz.) Baill was initially separated using AB-8 macroporous resins and further purified by HSCCC.The high performance liquid chromatography ( HPLC) ) method was used to determine the partitioning coefficient of crude extract in different solvent systems.The results showed the solvent system of n-hexane-ethyl acetate-methanol-water (6:5:5:4, V/V/V/V) was the best one for the HSCCC separation.A total of 6.3 mg of corosolic acid with a high purity of 97.6% was obtained in one step separation from 150 mg of crude extract. The method is of high separation efficiency, and great importance for the applications of corosolic acid in the food and medical fields.

Key words: high-speed counter-current chromatography, corosolic acid, Schisandra chinensis (Turcz.) Baill
