A simple precise and rapid Reverse Phase High Performance Liquid Chromatographic (RP-HPLC) method has been developed for quantitative determination of Regorafenib in tablet dosage form. In this method Hypersil Gold (C18, 150mm× 4.6mm id, 3μ) column with mobile phase consisting of Trifluoroacetic acid (0.2% v/v) and Acetonitrile in the ratio of (50: 50 v/v) at 400C in an isocratic mode was used. The detection was carried out at 260 nm and 20μL injection volume was selected with the flow rate 1mL/min. The linearity range of Regorafenib shows concentration between 5-200 μg/mL. The regression coefficient obtained was 0.999. Retention time of Regorafenib was found to be 6.49 minutes. Acetonitrile and Water in the ratio of (3:1) was used as a diluent. The method was validated as per ICH guidelines and is simple, fast, accurate, precise and can be applied for routine quality control analysis of Regorafenib in tablet dosage form.

Abstract A simple and fast analytical method is described for the quantitative determination of low levels of paraquat residues in water. The method involves extraction and concentration of paraquat in water by using a C18 Sep-Pak cartridge followed by reverse phase high performance liquid chromatographic determination with ultraviolet detection at 257 nm. Recoveries of paraquat from spiked samples were above 93% with a coefficient of variation of 6.1%. The method can be used for water samples with paraquat concentrations as low as 0.05 ppm.

Abstract Methapyrilene hydrochloride (MP·HCl) was extracted from feed with methanol and determined by reverse phase partition chromatography in less than 15 min, using isocratic elution with acetonitrile-1.1% ammonium carbonate (1 + 1) as the mobile phase. This procedure was tested on feed treated with MP·HCl at levels of 125,500, and 2000 ppm. Recoveries were 104,95, and 96% with coefficients of variation of 2.4,1.6, and 0.6%, respectively. MP·HCl in feed was stable for 14 days. This method was also successfully used to determine MP·HCl in 3 sleep aid tablets.

Abstract A high performance liquid chromatographic procedure has been developed for the assay of phenprocoumon in tablets. In comparison to the present official USP assay procedure, it is equivalent in precision and accuracy and is faster and more specific. A mobile phase consisting of a 1% solution of acetic acid in acetonitrile-water (4 + 3) separates phenprocoumon from warfarin internal standard on a 6 μm octadecylsilane (ODS) column with UV detection at 311 nm. The method enables the concurrent determination of phenprocoumon and possible contaminants such as salicylic acid.
