Abstract:

The paper aims to solve the problem of low yield and low purity of phloridzin extracted by existing techniques of extraction and purification. The leaves of Lithocarpus polystachyus were used as experimental materials, and the extraction and purification techniques of phloridzin from L. polystachyus were studied by using extraction method. The optimum extraction condition of phloridzin was determined as follows: crushing phloridzin and sieving with 30-mesh, the ethanol concentration of 75%, the ratio of material to liquid of 1:15, the immersion time of 24 h, the ultrasonic time of 20 min, the centrifugation time of 15 min and the methanol concentration of 50%. Under this condition, the average yield and purity of phlorizin were 7.63% and 91.10%, respectively.

Key words: Lithocarpus polystachyus, phlorizin, extraction, purification, yield, purity
