Abstract: Objective To optimize the extraction technology of phlorizin in litchi pericarp. Methods With different
concentrations of ethanol as solvents, the phlorizin in litchi pericarp was obtained by extraction method, heat reflux
extraction method, ultrasonic extraction method, respectively, and was determined by HPLC. The optimal extraction
4
technology was attained by L9(3 )orthogonal test. Results The extraction yield was higher for heat reflux extraction
method, and the optimal extraction technology was that 40% ethanol solution refluxing for 10min. Conclusion The
optimal extraction technology can be used for the extraction of phlorizin in litchi pericarp.
