QUANTITATIVE DETERMINATION OF SELENIUM IN ASTRAGALUS AND THYME OFFICINAL PLANTS
The content of selenium organic forms in Astragalus and Thyme officinal plants was determined by means of spectrophotometry method using phenylthiourea as a reagent. The selenium content estimated spectrophotometrically is equal to: 11750 μg/kg in Astragalus and 450 μg/kg in Thyme. The amount of selenium in these plants determined earlier by means of mass-spectrometry method is equal to 12000 μg/kg and 600 μg/kg, respectively.
