Primary study on macroporous resin for purification of flavonoids in cassava leaves

Kaimian Li

Abstract

The purified condition of macroporous resin was optimized,and the technological parameters of purifying flavonoids in cassava leaves were established.The adsorption and desorption performance of macroporous resins(HPD100、D151,001×1.1,NKA-9,H103 and D101)on flavonoids in cassava leaves were studied,and correlative technical parameters were investigated.Among these six macroporous resins,the optimum macroporous resin HPD100 was screened out,with high desorption (208mg/g dry weight)and desorption rate(96.78%).70% ethanol∶macroporous resin (7∶1,v∶v)could accomplish desorption completely.
