Abstract

An accurate, simple, sensitive and selective reverse phase liquid chromatographic method has been developed for the determination of Diclofenac sodium, Vitamin B₁, Vitamin B₆ and Vitamin B₁₂ in their pharmaceutical preparations. The determination of Diclofenac sodium was carried out on Phenomenex ODS, C-18 (150 x 4.6 mm) 5μ column using a mobile phase consisting of buffer: acetonitrile (40:60). The flow rate and run time were 1ml/min and 10 minutes respectively. The wavelength was 254 nm.  The determination of Vitamin B₁ and B₆ was carried out on Inertsil ODS, C₁₈ column (250 x 4.6mm;5µm) using a mobile phase consisting of a mixture of 1000mL of Sodium 1-hexane sulfonic acid solution, 730mL of water, 270mL glacial acetic acid of  and 10ml of methanol. The flow rate and run time were 1.5ml/min and 10 minutes respectively. The wavelength was 284 nm. The determination of Vitamin B₁₂ was carried out on Phenomenox ODS, C-18 column (150x4.6mm;5µm) using a mobile phase consisting of a mixture of water: acetonitrile (87:13) containing 0.25mL of  Trifluroacetic acid. The flow rate and run time were 1.2ml/min and 10 minutes respectively. The wavelength was 361 nm. The developed method was found to be simple, specific, robust, linear, precise, and accurate for the determination of Diclofenac sodium, Vitamin B₁, Vitamin B₆ and Vitamin B₁₂ in pharmaceutical formulations.
