We have studied the effect of oil pollution on the biochemical protective systems of plants. As a test object we used sedge acute (Carex acuta L). The analyzed plants were collected from areas of oil spills on the Maisky, South Balyksky and MaloBalyksky fields in Tyumen region. Oil pollution causes becoming lipid peroxidation products in plant cells such as Schiff bases and diene conjugates. The damaging effect is neutralized by the biochemical protective system of plants (flavonoid and phenolic). Phenolic compounds have adaptogene and stimulating effect. Flavonoids are reducing agents, and can protect cells against oxidative stress. The damaging effect of oil pollution is manifested in the reduction of the concentration of flavonoids in the sedge acute on sites contaminated by oil. Adaptation of the plants to the oil pollution expressed increasing concentration of phenolic compounds and reducing the content of diene conjugates and Schiff bases in the plant cells.
