Composition of woody greens essential oils Abies sibirica and Pinus sylvestris, native to the Republic of Buryatia

As a result of the study, from the woody greenery of Abies sibirica and Pinus sylvestris, growing in the Republic of Buryatia, essential oils (EO) were isolated by hydrodistillation, the yield of which was 4.54.6% and 1.11.2%, respectively, calculated on absolutely dry raw materials. The composition of the essential oil was studied by gas chromatography-mass spectrometry on an Agilent Packard HP6890 N gas chromatograph with a quadrupole mass spectrometer (HP MSD 5973) as a detector. The dominant components of essential oils for Abies sibirica are bornyl acetate (31.8237.57%) and camphene (19.6519.97%), for Pinus sylvestris α-pinene (25.7832.34%), limonene + β-fellandren (7,5811.40%) and 3-Karen (1.7214.46%). More than 90% of essential oils are constituents belonging to the group of monoterpenoids, which have a wide spectrum of activity against pathogens, which makes it possible to use these EMs as independent drugs or as components of drugs.
