Determination of Content and Content Uniformity of Oleanolic acid in GXLP by HPLC
Abstract:Objiective: To establish a method for determination the content and uniformity of Oleanolic acid in GXLP. Method: The Kromasil C18 (4. 6 × 150mm, 5um) was used and mobile phase was acetonitrile -water- phosphoric acid (75: 25: 0. 42), and its temperature was used at room temperature, with the flow rate of 1.0 ml · min- 1 and the wavelength of detection of 210 nm, and the injection amount of 10lxl. Results: The linear ranges of Oleanolic acid was at 0. 592 -2. 96μg (r = 0. 9997), the average recoveries (n =5) was 99.06% with RSD 1.78%. Conclusion: The method was simple, accurate, and can be used for the quality control of GXLP.
Keywords:GXLP  Oleanolic acid  HPLC
