Whether obtained by any method or technology, they do not lose their quality, even if stored for a long time (years), and remain safe and effective. The replacement of imported medicines with local phyto-drugs and the increasing use of essential oil plants in various sectors of the economy require the study of this group of plants. For this purpose, essential oils of 3 juniper species of Hirkan flora were obtained and their yield percentage was calculated. The yield of essential oil for Juniperus polycarpos - 1.4%; Juniperus oblonga - 1.0% and Juniperus sabina - 1.2%. The highest yield of essential oil was recorded in the type of multi-fruited juniper. The obtained essential oils are yellowish-yellow in color and have a specific pleasant odor. The article presents the results of the analysis of essential oil of Juniperus oblonga by gas chromatography and the composition of the essential oil. Chromatographic analysis revealed that thiujone (35.21%) and alpha-terpinene (19.78%) components had higher concentrations, while camphor (0.33%) and estragole (0.16%) components had the lowest concentrations.
