[ Objective] This study aimed to optimize the conditions for purification of total flavones from litchi pericarp by macroporous absorption resin. E Method] The flavones adsorption rates and desorption rates of macroporous absorption resins (AB-8, HPD-600, D101 ) were compared, and the technological parameters of D101 during the purification process were investigated. E Result] D101 macroporous absorption resin was ap- propriate for the purification of total flavonoids from litchi pericarp. The optimal technological conditions were selected .. the pH of sample solution was 5.0; concentration of sample solution was 4 mg/ml, with a volume of 2.5BV; 80% ethanol was used as elution solution, with a volume of 2.0BV. [ Condusion] The content of total flavones achieved 83% after separation by D101 macoporous absorption resin. 展开更多
