摘  要:
[Objective] This study aimed to optimize the conditions for purification of total flavones from litchi pericarp by macroporous absorption resin.[Method] The flavones adsorption rate and desorption rate of macroporous absorption resins(AB-8,HPD-600,D101) were compared,and the technological parameters of D101 during the purification process were investigated,including on-column liquid pH,flavoneconcentration,on-column liquid volume and volume fraction of elution solution.[Result] D101 macroporous absorption resin is appropriate for the purification of total flavonoids from litchi pericarp.The optimal technological conditions were:on-column liquid pH=5.0;on-column liquid concentration was 4 mg/ml,with a volume of 2.5 BV;elution solution was 80% ethanol,with a volume of 2.0 BV.[Conclusion] The content of total flavones achieve 83% by using the method.
