【摘要】 目的研究葛根素精制的最佳组合工艺。方法利用已研究的溶解剂、除杂剂和沉淀剂选择结果以及树脂、氧化铝、硅胶、粉煤灰、活性炭的柱层析方法进行组合工艺研究。结果优化的3个工艺产品的平均纯度分别为99.06052%、99.22620%和99.69880%,回收率的平均值分别为44.180%、44.438%和42.642%。结论本研究优化的最佳工艺可行,葛根素纯度超过99%,回收率达40%以上。更多还原

【Abstract】 Objective To study the best process of puerarin refined. Methods Results of the research on the selection of dissolved agent,agent and precipitator,and column chromatography of the resin,alumina,silica gel,fly ash and activated carbon were used to study the combined process.Results The average purity of optimization of the three craft products were 99. 06052%,99. 22620% and 99. 69880%. The yield of average values were44. 180%,44. 438% and 42. 642%. Conclusion This study optimized the optimum process is feasible,puerarin purity is more than 99%,the yield is above 40%.更多还原
