| Zusammenfassung: | Production of high-purity peiminine and fritimine by high-speed counter-current chromatogram technology is carried out by taking peimine as sampling substance, forming fixed-phase and flow-phase solvent system, pumping fixed-phase and flow-phase into column simultaneously, rotating host, sampling by sample injector, inspecting elution solvent, accepting object component and collecting to obtain the final product. The solvent system comprises chloro-alkane,fatty alcohol, aliphatic ketone and dilute acid solutions. It's cheap and convenient. |
