Essential oil of Juniperus, grown under the canopy of spruce bilberry-sphagnum, is a liquid of light yellow color. The content of essential oil in shoots Juniperus was 0,81%. 39 components were identified in essential oil. Mass fraction of identified components accounted for 86% of total composition essential oil. Monoterpenes in identified components occupy 90,5%, 0,4% sesquiterpenes, alcohols 7,5% and ethers to 1,6%. As part of essential oil of Juniperus communis 96 components have a concentration of less than 1%, 10 components from 1–5%, 4 components – more than 5%. Higher concentrations noted for components such as α-pinene 27,2%, β-pinene 22,4%, 3-carene 7% and β-phellandrene 5,7%. Component composition of essential oil of Juniperus communis is characterized by geographical variability. The yield of essential oil of juniper shoots have similar values with the yield of essential oil of pine (Pinus pumila (Rall.) Regel.) in the Khabarovsk region, but the content of fractions monoterpenoids superior pine and faction sesquiterpenoids inferior.
