Artemisia
, one of the largest genera in the 
Asteraceae
family, including more than 
350 species, is wide distributed in the temperate regions of the northern hemisphere 
such as Asia, Europe and North America [1]. 81 species of Artemisia, grow in the 
territory of Uzbekistan [2].
Air-dried plant (10 kg) of 
Artemisia porrecta
was extracted with 90% ethanol at 
room temperature, with 5 time for 24 h. After remove the solvent under vacuum 
pressure at 45°C, a crude extract fractionated by
