Abstract
A quick and sensitive reversed phase high performance liquid chromatography (HPLC) method has been developed in Indian surgical patients to determine the concentration of Propofol In human plasma. Propofol can be isolated from human plasma by adding 1ml precipitating solution which consists of acetonitrile and perchloric acid (67:33) mixture, which also contains dibutylpthalate (1mg/ml) as an internal standard. The sample is mixed for two minute on a vortexer. The plasma substance precipitated by acetonitrile and perchloric acid are further separated by centrifugation. The supernatant is directly injected into the HPLC system with the help of autosampler.
The analysis was carried out using column 250 × 4.6 mm column packed with10-μm Spherisorb reversed phase octadecyl silane particles (C 18 ). The 500ml of mobile phase (67:33:0.04) consisted of 335ml of acetonitrile and 165ml of distilled water and 200μl of acetic acid maintaining the pH 4.0.The flow rate of the mobile phase was 1.5ml/ min. propofol was monitored by a UV detector at a 270nm wavelength. The limit of detection of propofol (in human plasma) was found to be 0.0001μg/ml while limit of quantification was found to be 0.001μg/ml for a 20ul injection volume.
