Development and Validation of Noscapine In Bulk and Pharmaceutical Formulations by RP-HPLC Method

A simple, specific, quick, isocratic Reversed Phase High Performance Liquid Chromatographic method was developed and validated for the analysis of Noscapine. RP-HPLC method was developed on a Symmetry C-8 (4.6 × 150 mm), 3.5 µm particle, reversed-phase column. The mobile phase was 0.1% octane sulphonic acid (pH- 3): acetonitrile, 40:60 (v/v) at a flow rate of 0.8 ml/min. and the eluate was monitored at 260 nm. The retention time of the drug was found to be 2.314 min. The method was linear over the range of 4-8 μg/ml with a regression coefficient of 0.999 and validated with respect to accuracy, precision, linearity, and specificity, limit of detection and limit of quantization as per the guidelines of International Conference for Harmonization (ICH). This method can be used in the industries for determination of Noscapine to analyze the quality of formulation without interference of the excipients.
