[Study on the technics of adsorption and purification of baicalin by different macroporous resins].

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.
