RESUMEN
Objective To assess the influence of different processing technique on the quality of Exocarpium citri grandis.Methods The RP-HPLC method was adopted to determine the naringin content in Exocarpium citri grandis.The chromatographic conditions were: Kromasil ODS column(250 mm?4.6 mm),mobile phase being methanol-water-acetic acid(35∶61∶4),flow rate 1.0 mL/min,detection wavelength at 283nm and column temperature at 25 ℃.Results There were obvious differences in the naringin content of Exocarpium citri grandis which was processed by different methods: the naringin content processed by electro static drying method was much higher than that by bake drying method, natural drying method and vacuum drying method.Conclusion The electro static drying method is the best way for drying Exocarpium citri grandis.
