Study on process of puerarin refined / 中国生化药物杂志

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 were 44.180%, 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%.
