Abstract
Piroxicam was extracted from acid medium into chloroform and isolated on a thin layer of silica gel with the use of the system chloroform - absolute ethanol - benzene - aqueous ammonia (20:15:15:0.5). The intensity of fluorescence of stains was measured densitometrically (an Hg lamp, a filter FL - 39, 330 nm). The limit of detection of the stain is 0.020 microgram/ml of plasma.
