[The search of antioxidants in plant root's extracts of the carline thistle].

The carrying out tests of water-extracts of carline thistle (plant pink, Caryophyllaceae) in Kazakhstan (extract 1) and gathered in the Primorye region (extract 2). The method of spectral and thin layer chromatography silicagel plates contain phenolys components. It is found out that both extracts contain the same bonds with the max, uptake of long waves lambda = 282 hm and lambda = 260 hm. Besides, extract 2 has significant quantity of substances with the max, uptake lambda = 272 hm and substance with the max, uptake lambda = 330 hm. When determining with the help of standard tap the chemical nature of the substances, which have antioxidant characteristics, we settled out that antioxidant of soapwort possibly can be coffee acid and nonpolar flavonoid of unstated nature.
