title: [Use of chromatospectrometric methods for quantitative evaluation of flavonoids in complex tablets].
abstract: In the article are shown the results of quantitative evaluation of Flavonoids using Chromatospectrophotometric method, based on color reaction with aluminium chloride. The optimized conditions of Flavonoid's extraction from complex tablets were developed: the right substance, time and temperature for extraction were selected, accordingly - alcohol of 95%, 90 min time and the room temperature. The selected Chromatospectrophotometric method makes possible the accurate evaluation of the content of Flavonoids in complex tablets. Relative error of measurement in the state of confidence probability equal to 95 doesn't exceed ± 5,0%. The margines for content of Flavonoids in one tablet were defined as 20 to 50 mg.
