概要
An Innovative Stability Indicating RP-HPLC Assay Method for the Determination of Caroverine in Pharmaceutical Bulk and Tablets
Raza A and Ansari TM
An innovative, quick and easy reversed phase high performance liquid chromatographic method is elaborated and authenticated for the quantitative determination of caroverine in pharmaceutical bulk material and tablets. Shimpack CLC-ODC (C18) column was used. The mobile phase acetonitrile and buffer solution (30:70) pH 4.9 is transmitted at a flow rate of 1 mL/min. The eluent was observed using UV detector at 225 nm. The recent developed RP-HPLC method is specific, accurate, precise and linear (R2>0.998) within the range of 2-150 μg/mL concentration. The limit of detection and quantification is 0.068 μg/mL and 0.201 μg/mL respectively. The newly proposed method is applied to determine caroverine in pharmaceutical tablet formulations. The developed method is optimized using samples generated by forced degradation studies. Results of analysis are validated statistically. The method was selective, precise, accurate and can be used for routine analysis of caroverine in quality control laboratories of pharmaceutical industries.
