Abstract The present invention solves the problems of high solvent and stuffing consumption, limited purity, etc. during batch treatment, improves operation environment and reises automatic production level and features that the adoption of simulating moving-bed chromatographic system with reverse silica gel as stuffing and methanol-water mixture as flowing phase. The material is decontaminated before entering to the simulating moving-bed chromatographic system and the product is concentrated, recrystallized to obtain purity over 90%.
