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
