Optimization of the Extraction Technology of Naringin from Aurantii Fructus Immaturus by Orthogonal Test

OBJECTIVE：To optimize the extraction technology of naringin from Aurantii Fructus Immaturus. METHODS：Single factor test was used to investigate the effects of extraction solvent and solvent concentration on the transfer rate of naringin. The extraction technology was optimized by L9（34）orthogonal test with the amount of solvent,extraction times and extraction time as factors using transfer rate of naringin as index. RESULTS：The optimal extraction technology was as follows：6-folds 70% ethanol,extracting for 3 times,30 min each time. CONCLUSIONS：The technology is stable and has high extraction rate,and can provide reference for large-scale industrial production.
