Flavonoid content in the roots of caraway plants cv. Kończewicki and the antioxidant activity of extracts from those roots were determined in the first year of cultivation. The experiment revealed a significant relationship between the concentration of flavonoid compounds and the age of caraway roots. During the vegetative season the concentration of flavonoids in caraway roots gradually increased and ranged from an average level of 0.153 mg·g⁻¹ of air-dry matter(a.d.w.) in June to 0.512 mg·g⁻¹ a.d.w. in October. The largest amounts of these compounds were contained in the roots of the plants grown in 2006 (an average of 0.312 mg·g⁻¹ a.d.w.).The ability to scavenge the DPPH radical by the extracts from caraway roots increased in direct proportion to the length of the vegetative period, flavonoid content and extract concentration.
