Abstract:
Objective To optimize the purification technology of total flavonoids from the Tripterospermi Chinensis Herba by macroporous resin. Methods The purification abilities of six kinds of macroporous adsorption resins for total flavonoids from Tripterospermi Chinensis Herba were studied with the adsorption and desorption rates as the index by static adsorption and desorption experiments. The column liquid concentration, adsorption rate, and the loaded amount were studied by using dynamic adsorption experiments. The optimal desorption technology was examined by orthogonal experiment. Results AB-8 macroporous resin was found to have good adsorption and desorption effects. The optimal purification conditions were as follows:the column liquid concentration was 5.285 mg/mL, adsorption rate was 2 BV/h;the loaded amount was 17.62 mg/mL. The sample was eluted by 10%ethanol with 4 BV and 50%ethanol of 5 BV at a flow rate of 4 BV/h. The purity of total flavonoids increased to 61.95% after the purification, and the yield was 87.28%. Conclusion This optimized process was stable, feasible and suitable for separation and purification of total flavonoids from Tripterospermi Chinensis Herba.
