Abstract: | Objective:To establish a method of determination of isoniazid tablets by HPLC. Methods: BP - HPLC used Agilent ZORBAX SB -C18 column(5um,4. 6 × 250mm) ,mobile phase was composed of methanol - water - glacial acetic acid(44:55:1) ,The flow rate was 1.0ml/min with detection wavelength at 263nm. Results:Isoniazid in the range of 0. 032 - 0. 160ug a good linear relationship: (r = 0. 99995, n = 5 )The average recovery was 97.07%, BSD = 0. 9%. Conclusion:This method's accurate and repeatability is good. |
