Quantitative flavonoid variations of Artemisia vulgaris L. and Veronica chamaedrys L. in relation to altitude and polluted environment

Abstract

Influence of altitudinal gradient and polluted environment on externally accumulated flavonoid aglycones were examined. Contents of apigenin in Veronica chamaedrys L. and quercetin 3,7,3’-trimethyl ether in Artemisia vulgaris L. were determinated. The highest apigenin level was found in populations at alpine regions, whereas no relation was found between quercetin 3,7,3’-trimethyl ether and altitude. The largest amounts of quercetin 3,7,3’-trimethyl ether was found in samples collected from industrial polluted habitats. Ecological significance on external flavonoid aglycones is discussed.
