The mobile phase employed was acetonitrile : water : glacial acetic acid (65 : 32.5 : 2.5, v/v/v) at a flow rate of 1 ml/min. The column effluent was monitored within 8 minutes by diot array detection at 247 nm. The retention time of flurbiprofen was found to be 3.73 minutes. In the concentration range of 2 - 20 μg/ml, there was a tight linear correlation between peak area y (mAU.min) and sample concentration x (μg/ml) according to the equation y = 0,680x as the squared correlation coefficient R 2 was 0.9993. The limit of detection and limite of quantification were respectively 0.05 and 0.15 μg/ml. The method was specific to flurbiprofen with good precision and accuracy. The percentage recovery was ≤ 100 ± 2%, the relative standard deviation of the repeatability was ≤ 1.71% and the relative standard deviation of the intermediate precision was ≤ 2.34%.
