Objective:To optimize purification technology of compound Tongmai granules by macroporous resin.Method:Taking adsorption-desorption rate of total phenolic acid and puerarin as indexes
effect of the concentration of sample solution
diameter-height ratio
elution agent on purification technology of compound Tongmai granules was investigated by single factor test.Result:AB-8 macroporous absorption resin was the best resin
optimum purification technology was as following:the concentration of sample solution 110 g·L-1
diameter-height ratio of resin column 1∶10
ratio of resin-material drug 2.8∶ 1(adsorbed 3 h)
eluted with 2 BV water
then eluted with 6 BV 50% ethanol
collected eluent.Conclusion:This optimized purification technology was reasonable and stable
it could be extended to large-scale production applications.
