INVESTIGATION OF THE ESSENTIAL OIL OF EUROPEAN SPRUCE ROOTS (LAT. PICEA ABIES H. KARST, PINACEAE FAMILY)

The article is devoted to the study of essential oil extracted from the roots of European Spruce (Lat. Picea abies).The aim is to establish the component composition of the essential oil and the peculiarities of its localization in the roots of European Spruce.Materials and methods. The objects of the study are the roots of European Spruce not longer than two centimeters in diameter, peeled and dried. The study of their anatomical signs was carried out according to the methodology of the State Pharmacopoeia of the Russian Federation (the XIII-th edition) with the”Biomed-6” microscope using the DCN 510 nozzle. The essential oil was obtained by hydrodistillation of European Spruce roots using the device of Clevenger by Method 2 of the State Pharmacopoeia of the Russian Federation (the XIII-th edition). The component composition of the essential oil was determined by an Agilent 7890A gas-liquid chromatograph with an Agilent 5975C mass-selective detector.Results and discussion. As a result of the microscopic examination of the roots of European Spruce, it was established that the essential oil is localized mainly in resinous courses located in the wood of the root. In the central part of the root, resin moves are of a larger diameter. More than 18 components were found in the essential oil of European Spruce roots, 14 of them were identifi ed. The main component of the essential oil is sesquiterpene lactone – tanbergol.Conclusion. The essential oil of European Spruce roots has a unique component composition that includes components not characteristic for the essential oil of spruce greenery. The difference in the component composition indicates the difference in properties and pharmacological activity. Further studies are of interest for determining the prospects of using European Spruce roots.
