Determination of Naringin Content in Rhizoma Drynariae by High Performance Liquid Chromatography

摘要

[Objectives]To accurately determine the naringin content in Rhizoma Drynariae.[Methods]The high performance liquid chromatography(HPLC)method was applied in the determination of the naringin content in Rhizoma Drynariae.The sample was sonicated at room temperature.The mobile phase was 0.1%phosphoric acid-acetonitrile(75∶25),detected by diode array detector at the wavelength of 284 nm,and quantified by external standard method.[Results]The linearity of naringin was good in the concentration range of 5-500μg/mL with a correlation coefficient of 0.9999.[Conclusions]This method has good linearity,easy operation,correctness and reproducibility as required,and is expected to provide a method for the determination of naringin content in Rhizoma Drynariae.
