Abstract

Plants of Artemisia L. genus are important source of flavonoids – a group of biologically active substances, which are widely used in the perfume, alcoholic beverage, pharmaceutical industry and medicine. Flavonoids have antiseptic, anti-tumor, anti-inflammatory, antibacterial, antituberculosis actions. Therefore, testing and introduction of many types of Artemisia to the culture, and their selection in Kazakhstan is up-and-coming. Qualitative composition of wormwood Artemisia scopariaWaldst. et Kit flavonoids collected in Almaty and Ile-Balkhash region in 2013 year was studied by gas chromatography-mass spectrometry method. Samples were prepared by extraction three times with 40% ethanol solution. During the identification of flavonoids by gas chromatography-mass spectrometry pre-derivatization of the compounds was carried out by N,O-Bis(trimethylsilyl) trifluoroacetamide, which is the most reactive derivatizing agent to increase the volatility and thermal stabilityofstudied substances. Kaempferol and quercetin were found as a result of analysis.
