Two methods were developed for the determination of dapagliflozin (DAPA) in pure form and in tablets. The procedure utilized was UV-Visible Spectroscopy and RP-HPLC with PDA detector to quantify DAPA in bulk and tablets. The sensitive linear range was identified for both methods within 0.5-5.0μg/mL. The linear regression analysis was identified for both methods with correlation coefficient(r)>0.99. The LOD and LOQ values were found to be 0.05 μg/mL and 0.5 μg/mL for the method by UV-Spectroscopy. The molar absorptivity (ε) was calculated as 1.27 X 105 L.mol-1cm-1. The RP-HPLC method produced LOD and LOQ values of 1.0 ng/mL and 0.5 μg/mL. Both methods were simple, precise, reproducible to quantify the amount of unknown in bulk as well as in tablets and estimated accurately within the range of 100.0±0.5%. Statistical analysis was performed on the data obtained. There was no significant difference between the developed and reported methods with p>0.05. Both methods can be applied for routine analysis of DAPA in bulk and tablets with good accuracy and precision.

A simple, precise, accurate, and rapid reverse phase-high performance liquid chromatography (RP-HPLC) method with UV-Visible detector has been developed and subsequently validated for the simultaneous determination of amlodipine besylate(AML) and celecoxib(CEL) in their combined tablet dosage form. The separation was based on the use of a Flowrosil C18   analytical column (250 × 4.6 mm, i.d., 5 µm). The mobile phase consisted of a mixture of 80 volumes of acetonitrile and 20 volumes of water. The chromatography was performed by isocratic elution at a flow rate of 1 mL/min. Analytes were detected at 250 nm, with linear calibration curves at concentration ranges of 2-12 µg/ml and 50-300 µg/ml for AML and CEL respectively. The retention time of AML and CEL were 1.98 and 3.15 min respectively. The recoveries obtained were 99.46‒101.36% for AML, 99.57‒101.42% and 99.96–100.87 % for CEL. The method was validated according to International conference of harmonisation guidelines in terms of accuracy, precision, specificity, robustness, limits of detection and quantitation, and other aspects of analytical validation. The developed method was applied successfully for HPLC analysis of commercial pharmaceutical products including AML and CEL. Keywords: Amlodipine besylate; Celecoxib; RP-HPLC.

Repeatability And Reproducibility

An analytical method for determination of the biogenic amines: tryptamine, putrescine  histamine, phenylethylamine, tyramine, cadaverine, spermidine and spermine in red and white wines using pre-column derivatization with dansyl chloride (DnsCl) and reversed phase-high performance liquid chromatography with diode array detector (RP-HPLC-DAD) was developed and optimized. Concentration of DnsCl, pH, time of reaction and evaporation under nitrogen were tested and optimized. Best recoveries, ranging from 72 to 102 % were obtained for all analyzed amines applying derivatization with 10 mg/mL of DnsCl for 1 h at 60 oC and pH 9. The developed method showed excellent linearity with R2>0.99 for all tested amines. The accuracy was checked with the standard addition method showing satisfactory recovery, good repeatability and reproducibility. The optimized and validated method was applied for analysis of white and red wines from Macedonian origin, observing higher total amounts of biogenic amines in red wines.

A simple and precise RP-HPLC method for the estimation of Erdafitinib in tablet dosage form was developed and validated. The chromatographic separation of the drug was done with a Hypersil™ ODS C18 Column (150 mm × 4.6 mm i.d., particle size 5 μ) using 20mM sodium acetate buffer (pH 4. ±0.02), methanol and acetonitrile (60:10:30 v/v/v) as a mobile phase. The instrument was set at flow rate of 1.0 mLmin-1 at ambient temperature and the wavelength of UV-visible detector at 310nm. The method showed excellent linearity over a range of 5-35 μgmL-1 for the drug. The correlation coefficient for Erdafitinib was noted to be 0.9999. The mean recovery values were found to be 99.77% and 100.88%. The results suggest that the proposed method could be suitable for quantitative determination of Erdafitinib in pharmaceutical preparations and also for quality control in bulk manufacturing. The F-test and t-test at 95% confidence level were applied on data for statistical analysis.
