| Summary: | Abstract Koenigia Weyrichii is a potentially valuable plant for the extraction of flavonoids. Growing in the Polar region, in particular in the Kola Peninsula, this plant accumulates high amounts of flavonoids. However, industrial pollution can lead to an increased content of various metals in plant material and extracts obtained from it. One of the methods of extraction bio-active components from plants is applying deep eutectic solvents. These solvents can extract not only bio-active components but also metals, including toxic ones. In this research extracts of K. Weyrichii were obtained with a mixture of choline chloride + glycerol with the addition of 10 – 50 wt.% of water. 60% v/v ethanol + water mixture was reference extractant. Various metals concentrations in extracts were estimate with mass-spectrometer with inductively coupled plasma. It is obtained that extracts based on deep eutectic solvents are characterized by low concentrations of toxic and rare metals, and relatively high concentrations of macro- and micro-nutrient metals. |
