Abstract: Objective:To optimize the technical parameters of separation and purification of total phenolic acid from Phragmites communis Trin. by macroporous resin. Methods:Based on desorption effect on total phenolic acid,the adsorption capability and desorption parameter were studied. Results:The optimum macroporous resin is HPD500,which has good regeneration ability and adsorption process according with Langmuir equation. 80% Ethanol at pH 8 was taken as desorption solution,and 9.8% purity forulic acid sample is obtained. Conclusion:HPD500 macroporous resins is feasible to separate and purify total phenolic acid from Phragmites communis Trin.
Key words: macroporous resins, total phenolic acid, Phragmites communis Trin.
