ABSTRACT
A stability indicating RP-UPLC method was developed and validated for the simultaneous determination of Thiocolchicoside (TCC) and Aceclofenac (ACF) in tablet dosage form. The chromatographic separation was carried out by Thermo Scientific UPLC Instrument, Accela 1250 Pump, auto sampler with PDA detector, using column Thermo Scientific hypersil gold C18, (50 x 2.1mm) particle size 1.9μm using 5% ammonium acetate buffer and methanol in the ratio of 40:60, pH was adjusted to 5 with ortho phosphoric acid as mobile phase at a flow rate of 250 μl/min with the detection at 276nm. The run times of the TCC and ACF were about 0.697 and 1.125 minutes, respectively. The detector response is linear from 4.8 μg/ml to 7.2 μg/ml and 63.8 μg/ml to 96 μg/ml concentrations for TCC and ACF respectively. The linear regression equation was found to be y = 20620x-677.68 (r2 = 0.9996) for TCC and y= 50931x-319.3 (r2 = 0.9997) for ACF. The detection limit and quantification limit was 0.076μg and 0.23μg for TCC and 0.27μg and 0.71μg for ACF. The percentage of assay of TCC and ACF were about 99.50% and 99.96% respectively. The stability indicating capability was established by forced degradation experiments. The method was satisfactorily validated as per the ICH guidelines.
