In our study, we determined the biochemical and biological activity and toxicity of Artemisia sieversiana Willd., which grows in Mongolia. The amount of moisture, acidity, protein, oil, total and crude carbohydrates, vitamins and secondary metabolites in the dry weight of the plant was determined. A group of extracts was taken out and the chemical compounds of each group were identified by thin layer chromatography, and antioxidant activity was determined, IC50 value was calculated. IC50 values were calculated for hexane extract >200 μg/ml, chloroform extract 62.2 μg/ml, ethyl-acetate extract 54.8 μg/ml, n-butanol extract 55.9 μg/ml, aqueous extract 84.34 μg/ml. Ethylacetate, chloroform and hexane extracts showed growth inhibition zones for S.aureus ATCC2592 and B. subtilis ATCC6633. Each group of extracts was prepared at four different concentrations and the toxicity to Artemia salina crab larvae was determined and the LC50 value was calculated by Clarkson's toxicity index.
