Abstract

The article presents Data on the content of biologically active compounds (BAC) and the total phenolic antioxidants activity (TPA) evaluated for leaves and inflorescences of Achillea millefolium, Anthemis tinctoria, Artemisia absinthium, A. dracunculus, Leucanthemum vulgare, Pyrethrum balsamita, P. macrophyllum, Tanacetum vulgare. The leaves and inflorescences of the plants contain flavonols, catechins, tannins, carotenoids, pectin substances. High content of phenolic compounds was found in Artemisia dracunculus and Achillea millefolium (352.34 – 398.99 mg/g of DW). The highest level of catechins was registered in inflorescences (8.01 mg/g) and leaves (4.58 mg/g) of Artemisia absinthium. The content of pectin substances in the studied plants was quite high, with the biggest share of protopectins (50.6 – 95.9 mg/g). The maximum quantity of pectins was found in the leaves and inflorescences of Leucanthemum vulgare (11.2-12.7 mg/g), protopectins – in the leaves of Tanacetum vulgare (95.9 mg/g). The highest content of carotenoids was found in the leaves of plants, except for Leucanthemum vulgare. The highest antioxidant activity was recorded for water-ethanol extracts from leaves of Achillea millefolium (up to 1.09 mg/g) and inflorescences of Artemisia dracunculus (0.94 mg/g) plants due to the increased content of phenolic compounds, in particular flavonols and tannins, compared to the other species.
