Research on Active Selenium Polysaccharide in Artemisia Argyi

Abstract

In this article, the selenium content of selenium polysaccharide and its antioxidant activity in vitro in Artemisia argyi has been studied. The double tracts atomic fluorescence spectrometry is used to detect the total selenium content in the sample and that of selenium polysaccharide in the active ingredient of the sample. The salicylic acid method and pyrogallol autoxidation method are used to detect the scavenging activity of selenium polysaccharide on hydroxyl radicals and superoxide anion. which grows in Yutangba, a selenium mining area of Enshi—“City of Selenium in China”. Through a comparative experiment with Artemisia argyi growing in non-selenium mining areas, the results have shown that the antioxidant ability of selenium polysaccharide in Se-enriched Artemisia argyi is significantly stronger than that of pure polysaccharide. Therefore, Se-enriched Chinese herbal medicine is a good natural antioxidant, which is worthy of exploitation and utilization.
