The influence of anthropogenic factors on the quantitative content variation of phenolic compounds, waxes, tannins and pectins in the Siberian and Dahurian larch bark during one year is studied. It's found that the amount of phenolic compounds in the samples, prepared from Larch trees on territorial domain of Irkutsk city, is significantly greater than the other one, prepared from Larch trees of this city in 5 km. At the same time the pectin and wax content in larch bark, growing in the city domain, is slightly lower than in the sample, prepared from countryside trees.
