Adsorption properties of AB08 resin for purification of total flavone in Sophora flavescens

Hong Chao Gao

Abstract

Object To study the adsorption function of macroporous resin AB 8 for the purification of total flavones in Sophora flavescens Ait and the effects of concentration, pH, flow rate of the adsorbate and eluant Methods UV spectrophotometry was used to analyze the content of total flavone in S flavescens Results The appropriate adsorption conditions were: concentration of Sophora extract, 0 285 mg/mL ; pH=4; flow rate 3 BV/h, when 50% alcohol was used as eluant, the effect of desorption was satisfactory Conclusion AB 8 resin can be used to refine the total flavone in S flavescens
