A simple, specific and accurate reversed-phase high performance liquid chromatographic method was developed for the simultaneous determination of Capecitabine and Oxaliplatin, using a Hypersil BDS C18, 150x4.6 mm, 5μ column and a mobile phase composed of 10mM dipotassium hydrogen phosphate+0.1% TEA pH 5.0: Acetonitrile (50:50%v/v). The flow rate was 1.0 ml/min, and the detection wavelength was 245 nm. The injection volume was 20 μL. The retention times of Capecitabine and Oxaliplatin found 4.29 min and 5.52 min, respectively. Linearity was established for Capecitabine and Oxaliplatin in the range of 60-210μg/ml and 20-70 μg/ml, respectively. The percentage recoveries of Capecitabine and Oxaliplatin found to be in the range of 99.1-101.5% and 97.9-99.7 %, respectively. The proposed method validated for precision, accuracy, linearity range, and robustness. This method can successfully be employed for simultaneous quantitative analysis of Capecitabine and Oxaliplatin in the capsule.

Objective: A present investigation is based on method development and validation for the simultaneous determination of metoprolol and atorvastatin by reversed-phase high-performance liquid chromatography in its bulk and pharmaceutical dosage form using a biorelevant dissolution media (fasted state small intestinal fluid). Methods: The chromatographic separation technique performed by an isocratic method for this column used Inertsil ODS-3 (4.6×150 mm, 5 μm). The ratio of mobile phase used is phosphate buffer 4.8 pH: acetonitrile (35:65v/v), flow rate 1 ml/min, and analysis time 15.0 min, UV detection was at 244 nm. Results: According to the International Conference on Harmonisation Q2 (R1) guidelines, the method validation was done. Peaks were observed at 2.227 min and 5.819 min, concentration range of linearity was obtained at 50–250 μg/ml and 10–50 μg/ml, linearity correlation coefficients were 0.9997 and 0.9995, limit of detection was 0.33 mg/ml and 0.21 mg/ml, and limit of quantification was 1.08 mg/ml and 0.69 mg/ml for metoprolol and atorvastatin, respectively. Conclusion: The obtained results for this method validation are within acceptance criteria. This method was more economical and stable for routine analysis.

Liquid Chromatographic

A simple, sensitive and rapid high performance liquid chromatographic method has been developed for the determination of Propofol. The main focus of the method was to determine Propofol in solution form as well as in marketed formulation. Chromatographic separation was achieved on Inertsil ODS-3V column (250mm x 4.6mm; 5µm) with a mobile phase consisting of methanol: water (85:15), with a flow rate of 1.0ml/min (UV detection at 270nm). Linearity was observed over the concentration range of 10-110µg/ml with a regression equation y=88048x + 44524 and having a regression value (R2) of 0.999. The LOD and LOQ values found to be 10ng and 100ng, respectively. No changes found in ruggedness and robustness studies. The percentage of recovery was found to be 95.25% to 101.81%. Validation studies revealed that the method was specific, accurate, precise, reliable, robust, reproducible and suitable for the quantitative analysis in its pharmaceutical formulations.

An isocratic Reversed-Phase High Performance Liquid Chromatography method has been developed for rapid and simultaneous separation and estimation of two antibiotics, namely, nitazoxanide and ofloxacin, in human plasma. Separation was carried out on Altima C8 (150 x 4.6 mm, 5µ) column using a mobile phase of 0.1% ortho phosphoric acid: acetonitrile (50:50, V/V) at 260 nm. The retention time of nitazoxanide and ofloxacin was noted to be 4.850 and 7.949 min, respectively. The average % recovery for nitazoxanide and ofloxacin were 98.012 % and 94.176 %, respectively and reproducibility was found to be satisfactory. The linearity was investigated in the concentration range of 0.02-2 µg/ml (r2=0.9996) for nitazoxanide and 0.008-0.8 µg/ml (r2=0.9998) for ofloxacin. The lower limits of quantification were 0.0196 µg/ml and 0.0079 µg/ml for nitazoxanide and ofloxacin, respectively, which reach the level of both drugs possibly found in human plasma. The proposed method can be applied for etermination of nitazoxanide and ofloxacin from dosage forms during pharmacokinetic study.

A simple, precise and accurate high-performance thin-layer chromatographic method has been established for the determination of rutin in the stem extract ofHibiscus micranthusLinn. A flavonoid fraction of methanolic extract of the stem powder was used for the experimental work. Separation was performed on silica gel 60 F254HPTLC plates withn-butanol: acetic acid: water: ammonia 3:1:1:1(v/v), as mobile phase. The determination was carried out using the densitometric absorbance mode at 286 nm. Rutin response was linear over the range 50–400 ng/μL. The concentration of rutin in the flavanoidal fraction was found to be 9.93%. The HPTLC method was evaluated in terms of sensitivity, accuracy, precision and reproducibility.
