Popis: Introduction. Much attention is paid to the production of green products of aromatic plants from local raw materials, as one of the priorities implemented under the program “The Concept of the State Policy in the Field of Healthy Nutrition of the Population of the Russian Federation for the Period until 2020”. For the year-round consumption of green mass of plants, there are used different technologies of cultivation. Specific growing conditions (short light day and low light) in the autumn-winter period of highly productive plants in our country are possible only with the use of additional sources of artificial light. Material and methods. Studies of the effect of different growing technologies on the component composition of essential oil and volatile plant excreta using the example of peppermint carried out by chromatography-mass spectrometry with analytical complex «Clarus 600M» by Perkin Elmer (USA) (flame ionization) and mass spectrometry detectors with gas chromatography-mass spectrometry system Focus GC DSQ II by Thermo Scientific (USA). Results. The use of new technologies for growing ether-bearing plants may cause a change in the qualitative and quantitative composition of the essential oil and volatile plant excretions. Because of re-lighting by narrow cavity light, there have been changes in the qualitative and quantitative composition of the essential oil and volatile mint emissions. The disappearance of sabinene, bourbonene, myrtenol, colamen found in control samples and the formation of cumene, 3-hexyl-2-methylbutyrate, germacrene, carvone, cubenol, a decrease in the content of the main components: menthol, menton, benzyl alcohol, sabinene, bourbonene; an increase in the content of methylacetate, isomentone, isomenthol, neomentilacetate. With combined lighting, a reduction from 43 to 31 compounds was established with a decrease in their total content in the composition of the volatile fraction. Conclusion. Terpene hydrocarbons are the most hygienically significant substances belonging to the group of easily transformed substances, and oxygen-containing compounds (aldehydes, ketones, phenols, furans, pyrans, ethers) identified in the group of toxic and dangerous chemicals
