The effect of aerotechnogenic pollution from vehicles on the composition and content of phenolic compounds in the needles of Pinus sylvestris L. is studied with chromatographic analysis (HPLC). It was established that content of phenolic compounds near the highways in 53.7% fraction increases considerably from 37.9% - decrease, and 3.7 % is not changed. Among the identified phenolic compounds we had similar results. Activation of the synthesis was observed in 58.33% of fractions, inhibition - at 33.33%, neutral reaction - at 8.3%. In compounds with a pronounced increase in the activity of synthesis prevailed phenolcarbonic, hydroxycinnamic acids and flavonoids. Overall, our results clearly show that in the zone of strong contamination (near of urban highways) biochemical antioxidant protection Pinus sylvestris subsystem, including low molecular weight phenolic compound functions effectively, whereby the activity of the synthesis of most of these compounds have antioxidant properties, is increased. The composition of phenolic compounds in the needles of Scots pine Pinus sylvestris L., which preserve the high antioxidant activity in terms aerotechnogenic pollution studied in detail.
