Abstract

Objective: To ascertain the fittest technical parameters by studying the application of macroporous resins used to purify active components of baicalin.

Methods: To evaluate the ability of adsorption and re-adsorption of macroporous resins selected, the statical and dynamic adsorption-readsorption durations were also investigated to select the optimum macroporous resins, with the content of flavonoids as the standard.

Results: The optimum macroporous resins was HPD-100. In the adsorption cours, the ratio between the amount of medicinal materials and the volume of macroporous resins was 3.0 and there was no more absorbed when the ratio was 12.5; the optimum ethanol concentration was 50% in readsorption duration.

Conclusion: HPD-100 is the optimum macroporous resin to purify bailcalin and enhance its refined rate.
