Abstract:

The preparative high-speed counter-current chromatography (HSCCC) method was applied to isolate and purify ricinine from the crude extract of Ricinus cammunis L. seeds, and the purity of purification product was measured by HPLC and its structure was analyzed by MS and NMR. After being defatted using a mixture of petroleum ether and ethyl ether (2:1, V/V) twice, caster bean seeds without shell was subjected to ricinine extraction using 95% ethanol in a Soxhlet extractor followed by vacuum concentration and freeze drying. The preparative HSCCC was performed using a two-phase solvent system composed of chloroform, methanol and water (2:1:1, V/V). A total amount of 70 mg of ricinine with over 99.62% purity was obtained from 100 mg of the crude extract. Ricinine was identified as the main component in the crude extract by MS and NMR. The preparative HSCCC is suitable for large-scale preparation of ricinine with high purity.
