ABSTRACT

AIM: To study the technological parameters of the purification process of total flavonoids of Crataegus leaves with HPD-600 macroreticular resin. METHODS: Using orthogonal experiments,the adsorptive characteristics and elutive parameters of the process were studied by taking the elutive effects and purification ratio of total flavonoids of Crataegus leaves. RESULTS: Two significant factors which were the concentration of crude flavonoids solvent and elutant component were observed. CONCLUSION: The microwave-assisted extraction and purification process with macroreticular resin is employed,the content of total flavonoids is 80.75%, the rutin content is (1.38)%, The macroreticular resin can be used in the purification of flavonoids of Crataegus leaves.
