Bioanalytical Method Development and Validation for Determination of Rifampicin and Quercetin in Rat Plasma by UHPLC-MS/MS: Applications to Pharmacokinetic Study

Bioanalytical Method Development and Validation for Determination of Rifampicin and Quercetin in... Abstract UHPLC-MS/MS was utilised to quantitatively analyse Rifampicin and Quercetin-loaded Liquisolid compact in rat plasma. The UPLC Acquity C18 (1.7 μm, 2.1 × 15 mm) column and 0.5 ml/min were used to separate the analyte. In a low-pressure gradient mode, A: In water 0.1 % formic acid and B: In acetonitrile 0.1 % formic acid as the mobile phase. Sample pre-treatment was performed by protein precipitation technique with methanol and acetonitrile (1:1) from rat plasma. As an internal standard (IS), the analyte was found by tracking precursor-to-product ion transformations of 823 → 791.3 m/z for rifampicin, 303 → 257 m/z for quercetin, and 138 → 121 m/z for isoniazid in MRM mode. The proposed technique was validated for precisions (Intraday and Interday) accuracy, linearity, quantification at lower limits, and analyte recovery. The findings showed that the plasma samples inter and intra-day precision and consistency values were determined to be within the acceptable range. After orally administering Liquid solid compact and pure drug solution, which showed a substantial difference in the pace and extent of absorption, the method’s suitability for determining the pharmacokinetic profile of each drug was tested. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Analytical Chemistry Letters Taylor & Francis
