Abstract:Objective To compare the quality of Citrus reticulata Blanco processed according to Guangdong standard and Chinese Pharmacopeia based on the content of hesperidin.Method Hesperidin in Citrus reticulata Blanco processed from the two standards was analyzed on a Diamonsil C18(250 mm×4.6 mm,5 μm)column using methanolwater(40∶60) as mobile phase. The flow rate was 1.0 mL/min and detection wavelength 284 nm. Result The average content of hesperidin in Citrus reticulata Blanco processed by Guangdong standard was 4.276%, and that by Chinese Pharmacopeia was 4.257%, while no significant difference was noted in respect of the content between the two processings. Conclusion Similar qualities of Citrus reticulata Blanco are obtained from the two processings.
