Study of peculiarities of essential oil accumulation by common yarrow herb of synanthropic flora of Rostov region

Abstract. Aim - study the peculiarities of essential oil accumulation in common yarrow herb harvested in urban areas of Rostov region. Materials and Methods. Raw materials were collected along a country road with non-vibrant traffic, the North Caucasus railroad and along the M-21 highway with heavy vehicular traffic belonging to IA category. A step of 100 meters (from 1 to 300 meters) was chosen away from the studied highways. In addition, the raw materials were harvested in the area devoid of anthropogenic impact (control) and near the agricultural enterprise JSC "Aston". Results. For samples of control areas and agrobiocenoses we can note a higher content of essential oil than in samples of urban biocenoses. The maximum indicator of the essential oil content is noted for the sample harvested in the control area, devoid of anthropogenic impact, the minimum content - for the sample collected along the highway M-21. Conclusions. According to the studies we can conclude about the negative impact of anthropogenic impact, as well as the peculiarities of the growing area on the accumulation of essential oil in the grass of common yarrow.
