     a simple, precise and stability-indicating thin-layer chromatographic method for estimation of ropinirole hcl was developed and validated as per ich guidelines. the mobile phase consisted of acetone–cyclohexane–6 m ammonia solution (8:5.5:0.5, v/v/v). scanning the drug was done at 250 nm. compact spots for ropinirole hcl were found at an r f value of 0.51 ± 0.002. the linear regression analysis data for the calibration plots showed good linear relationship with r 2 0.9976 ± 0.0011 in the working concentration range of 100–3,000 ng spot−1. the method was validated for precision, accuracy, ruggedness, robustness, specificity, recovery, limit of detection (lod), and limit of quantitation (loq). the lod and loq were 12.89 and 42.53 ng spot−1, respectively. the drug was subjected to degradation; the peaks of degradation products were well resolved from the standard with significantly different r f values. hence, this method can be used for quality control assay of ropinirole.
