[Study on separation and purification of total flavones from Smilax china by macroporous absorption resin].
OBJECTIVE
To investigate the technological parameters of the purification process of total flavones from Smilax china with macroporous absorption resin.


METHODS
The technical process for purification of total flavones with the optimum macroporous absorption resin was screened by yield of total flavones product.


RESULTS
The D140 macroporous absorption resin had the best separating efficiency when the flavones content in the liquid was 0.5 g x mL(-1) equivalent to raw material, the volume of drug 18 BV (resin bad volume) with the adsorption-power 2 BV x h(-1), and the volume of 60% (mL x mL(-1)) ethanol as eluant 5-10 BV (resin bad volume) with desorption-power 1 BV x h(-1). The obtained flavones product has total flavones recovery rate of 84.72%.


CONCLUSIONS
The treatment of regenerated resin is easy, this method is advisable.
