This research was aimed to establish a versatile, sensitive, rapid and validated RP-HPLC method to analyze linagliptin in bulk as well as in pharmaceutical dosage forms. Liquid chromatography was performed on HPLC system and 20μl of samples were injected into a C18 column (150 x 4.6 mm i.d., 5μm particle size) and the eluents were monitored through a PDA detector at 239 nm. An isocratic method with a flow rate of 1 ml/min was used to elute the compounds with a mobile phase comprised of 70:30 v/v mixture of phosphate buffer (pH 6.8±0.2) and acetonitrile. The retention time of the compound was found to be 2.8 minutes. According to the ICH Q2(R1) guidelines, the method was validated by establishing several analytical parameters such as system suitability, specificity, linearity, accuracy, precision, limit of detection (LOD), limit of quantitation (LOQ), ruggedness and robustness to assay linagliptin. The method showed good linearity (R2 = 0.9981) over the concentration ranges of 40 – 60 μg/ml with a recovery between 99.48% ± 0.38% RSD to 100.22% ± 0.011% RSD, whereas the LOD and LOQ values were 0.05 μg/ml and 0.15 μg/ml, respectively. The relative standard deviation (% RSD) for inter-day and intra-day precision was not more than 2.0%. Hence, the proposed method can be applied accurately for research and routine analysis of linagliptin in bulk as well as different pharmaceutical dosage forms. Dhaka Univ. J. Pharm.

A simple, precise, specific, and accurate reversed phase high performance liquid chromatographic (RP-HPLC) method was developed and validated for determination of vinpocetine in pure and pharmaceutical dosage forms. The different analytical performance parameters such as linearity, accuracy, specificity, precision, and sensitivity (limit of detection and limit of quantitation) were determined according to International Conference on Harmonization ICH Q2 (R1) guidelines. RP-HPLC was conducted on Zorbax C18 (150 mm length × 4.6 mm ID, 5 μm) column. The mobile phase was consisting of buffer (containing 1.54% w/v ammonium acetate solution) and acetonitrile in the ratio (40 : 60, v/v), and the flow rate was maintained at 1.0 mLmin−1. Vinpocetine was monitored using Agilent 1200 series equipped with photo diode array detector (λ = 280 nm). Linearity was observed in concentration range of 160–240 μgmL−1, and correlation coefficient was found excellent (R2 = 0.999). All the system suitability parameters were found within the range. The proposed method is rapid, cost-effective and can be used as a quality-control tool for routine quantitative analysis of vinpocetine in pure and pharmaceutical dosage forms.

Abstract Background The present work is aimed at development and validation of RP HPLC method which is simple, specific, precise, and accurate for estimation of Sofosbuvir and its process-related impurity in bulk and pharmaceutical dosage forms. Extensive literature survey revealed no method for estimation of the above said. The chromatographic separation was achieved on Agilent Eclipse XDB-C18, 4.6 × 250 mm, 5 μm with mobile phase composed of 0.1% trifluoroacetic acid in 1000 ml of water:acetonitrile (50:50) using an isocratic mode of elution. Detection was made using UV detector at 260.0 nm and LC solution software for analysis of data. The developed method was validated according to ICH guidelines. Results The linearity of calibration curve for Sofosbuvir in concentration range of 160-480 μg/ml was good. The curve was linear for its process related impurity (Phosphoryl) in concentration range of 10-30 μg/ml. There exists a good correlation between peak area and analyte concentration. Retention time for Sofosbuvir was found to be 3.674 min and its impurity was 5.704 min. Relative standard deviation values for Sofosbuvir is 1.741 and its process related impurity is 0.043. LOD for Sofosbuvir and its impurity was found to be 0.01% (0.04 μg) and 0.03% (0.12 μg) respectively. LOQ for Sofosbuvir and its impurity was found to be 0.50% (0.125 μg) and 1.50% (0.375 μg) respectively. Conclusion All the results reveal that the proposed method was found to be highly sensitive, simple, precise, accurate, robust, and fast. Large number of samples can be analyzed in shorter time due to shorter retention times, so it can be successfully applied for routine analysis of Sofosbuvir and related phosphoryl impurity in bulk and pharmaceutical dosage forms.
