Abstract

Ascorbic acid has been measured with organic substances. Monosaccharide and disaccharides lowered results of measurement of an ascorbic acid in substances by 2, 6-dichlorophenol indophenol procedure. Tannins and flavonoids overestimate of measurement of an ascorbic acid by photometric methods. An experimental error of methods of measurement has been found out at presence of organic substances at sample.
