Voglibose is a potent α glucosidase inhibitor, used for the treatment of diabetes mellitus. For quantitative determination of voglibose in pharmaceutical formulations of low doses, simple, sensitive, accurate and precise LC-MS/MS method using electrospray ionization in positive mode was developed and validated. The method was found linear in the concentration range of 25.0-1200 ηg/mL with a correlation coefficient of 0.9998. The limit of detection (LOD) of the method was found to be 1.5 ηg/mL and limit of quantitation (LOQ) was achieved at 3.0 ηg/mL. The recoveries of voglibose from spiked samples at different concentration levels were found in the range of 98-102%. The proposed method was found suitable for quantitation of voglibose and for the determination of uniformity of content of the dosage units of the tablet formulations.

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.

A specific and sensitive method of liquid chromatography–tandem mass spectrometry was demonstrated for the experimental determination of venetoclax in human plasma utilising venetoclax-D8 as an internal standard. The column Xbridge C18, 50 × 4.6mm, 5 µm was used for attaining chromatographic separation by utilising 10mM ammonium formate and methanol as isocratic mobile phase in the composition ratio of 20:80 (V/V). The flow-rate selected was 0.7ml/min. Venetoclax and venetoclax-D8 are identified in multiple reaction monitoring (MRM) positive mode with proton adducts at m/z 869.53 →553.21 and m/z 877.14 → 553.23, respectively. For the successful extraction of drug as well as internal standard, liquid-liquid extraction technique was efficiently utilised. The developed technique was established in a linear concentration range of 5.0-5000.0 pg/ml along with correlation coefficient (r2) of 0.9994. Intra and inter-day precisions were found to be 0.7 to 1.90% and 0.7 to 2.0 % for venetoclax and venetoclax-D8, respectively. Accuracy was found to be within 98.6 to 101.99% and 99.17 to 101.14 % for venetoclax and venetoclax-D8, respectively. It was observed that throughout the bench top studies, post-operative stability studies and freeze-thawing cycles, venetoclax retained stability.

1,4-Dimethylnaphthalene (1,4-DMN) is effective sprout suppressant used in potato stores in many countries in the world. High residue levels of this compound on the potatoes and in other environmental samples are considered for human health and environmental risks. Determination of the residue requires specific analytical methods to be developed and validated. In this study, HPLC-UV was selected for validating a separation method based on reversed phase for the analysis of 1,4-DMN using 2-methylnaphthalene (2-MeN) as internal standard testing three HPLC systems. Under the same chromatographic conditions, all three systems achieved good separation on a Jones column (Hypersil ODS 5 μm, 250 mm × 4.6 mm) at ambient temperature isocratically using 70% acetonitrile as mobile phase at a flow rate of 1.5 mL min−1, 20 μL injection volume, a run time of 10 min, and a detection wavelength of 228 nm. All three systems showed high precision, good linearity, and low limit of detection (LOD) and quantification (LOQ); particularly, the SpectraSERIES UV100-autosampler system offered lower values of LOD (0.001–0.004 μg mL−1) and LOQ (0.002–0.013 μg mL−1) for both compounds. This system can be used for the quantitative determination of 1,4-DMN residue in potato and environmental samples.

Potassium Dihydrogen Orthophosphate

Aim: To develop a stability indicating Rp-UPLC method for the simultaneous determination of Lamivudine, Dolutegravir and their degradants in tablets. Methodology: The chromatographic separation was performed on BEH Shield RP18 (2.1 mmX100 mmX1.7 mm) using a isocratic mobile phase Potassium dihydrogen orthophosphate pH 3 adjusted with orthophosphoric acid: methanol (30:70,% v/v) at a flow rate of 0.5ml/min. Column was maintained at room temperature and eluents are monitored at 258 nm. Results: Retention times of the analytes were found to be at 0.81 and 2.78 mins for Lamivudine and Dolutegravir respectively. The calibration of peak area versus concentration, which was linear from 105 to 315 µg/ml for Lamivudine and 17.5 to 52.5 µg/ml for Dolutegravir, had regression coefficient (r2) greater than 0.999. The method had the requisite accuracy, precision and robustness for simultaneous determination of Lamivudine and Dolutegravir in tablets. Conclusion: The proposed method is simple, economical, accurate, precise and can be successfully employed in routine quality control for the simultaneous analysis of Lamivudine and Dolutegravir in pharmaceutical formulations.
