Darbinyan, Hranoush H. | Khachatryan, Hambardzum H.
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.
