Abstract
The annual dynamics of composition and content of groups of phenolic compounds (hydroxybenzoic acids, hydroxycinnamic acids and flavonols) and individual phenolics (gallic, protocatehuic, chlorogenic, caffeic, p-coumaric and cinnamic acids, hyperoside, isoquercitrin, rutin and avicularin) in the leaves of Spiraea media Fr. Schmidt, S. chamaedryfolia L. и S. hypericifolia L., growing in Novosibirsk in the areas with high and background levels of transport and industrial pollution were studied. The peculiarities of effects of environmental contamination and meteorological conditions on the content of phenolic compounds and their groups are revealed. The concentrations of the major constituents in leaves of the species decreased significantly in the urban area in comparison with the background one. The most stable annual decrease in the concentrations was found in the leaves of S. hypericifolia. The level of the annual variability of the number of phenolic components under the conditions of pollution increased (S. media, S. chamaedryfolia) or slightly changed (S. hypericifolia) compared with the control, and the level of variation in the concentrations of most constituents, on the contrary, decreased.
