Cedar elfin Pinus pumila (Pall.) Regel of the pine family – Pinaceae is a widespread plant in Eastern Siberia and the Russian Far East. Most studies of cedar elfin are devoted to the study of needles and woody greenery. Pine cones remain a poorly studied object, the chemical composition of which requires serious study to determine the prospects for further use. The aim of the work is to study the component composition and essential oil content in pine cones. To study the essential oil, samples of pine cones were harvested on the territory of the Magadan region, the Olsky urban district. The determination of the essential oil content in cones was carried out according to the methods of the State Pharmacopoeia of the XV edition. The component composition of the essential oil was determined using an Agilent 7890A gas chromatograph with a mass-selective detector. As a result of the study, it was found that a Clevenger device should be used to determine the content of essential oil in pine cones. The content of essential oil in cones is highest in July, slightly less in August, and in September there is no essential oil in the raw material. It has been established that July is the most favorable period for harvesting pine cones. The main component of the essential oil of pine cones is limonene. The proportion of the main component of the essential oil of pine cones, limonene, is higher in July, and the proportion of the undesirable component 3–karen increases in essential oil in August. The high content of limonene in the essential oil samples is a good prerequisite for further research and development of finished products.
