ABSTRACT:

The article deals with the study of patterns of change in the content of phenolic compounds of ordinary aspen bark (Populus tremula L.) depending on the geographical location of trees and growing conditions. The samples taken from the seven regions of Russia, namely Kirov, Kostroma, Yaroslavl region, Tatarstan, Komi, Mordovia, Mari El were analyzed in the work. The authors studied the dependence of the quantitative content of phenolic compounds in the extract of the bark Populus tremula L. depending on the geographic location of the trees (height above sea level, the area of forest vegetation and forest growth area) and growth conditions (type of site conditions, forest type, the sum of active temperatures). The content of flavonoid in the bark of aspen ordinary varied from 0.02% to 0.10%. The greatestamount of rutin was found in samples of bark Populus tremula L., harvested in the Republic of Tatarstan (0,10 ± 0,01%). Spectrophotometric and HPLC methods were used to determine the quantitative content of phenol compounds in the test samples of the bark.
