Optimization of Purification Technology for Alcohol Extract of K-CoxB-JN by Macroporous Resin

Objective: To optimize purification technology of total saponins, flavonoids and lignins from K-CoxB-JN by macroporous resin. Method: Taking the contents of total saponins, flavonoids and lignins as indexes,adsorption and desorption properties of 10 kinds macroporous resins were compared,based on these,maximum sample volume,sample flow rate and elution solvent were investigated by single-factor test. Result: D101 macroporous resin gave good static-dynamic and adsorption-desorption characteristics for all components,optimized purification technology was:crude drug concentration of alcohol extraction solution 0.5 g ·mL^-1,herbs-wet resin 1: 4,adsorption flow rate 2 BV ·h^-1, washed with 3 BV distilled water,4 BV of 70% ethanol as elution solvent.Under these conditions,purity of total saponins, total flavonoids and total lignins were enriched from 5.36%,0.3%,2.26% to 53.82%,3.01%,22.87%. Conclusion: This optimum purification technology of K-CoxB-JN was simple, stable and effective with good purification effect,it could be promoted in large-scale production.
