Background. In today’s world, there is an increased demand for natural essential oils as one of the sources of improvement of human life. This is due to the wide range of biologically active effects of essential oils, which determines their wide use in medicine, food industry, aromatherapy, cosmetology, technical cleaning products, etc. Expanding the range of cultivated essential plants contributes to the preservation of natural floral resources and enriches the range of natural essential oils. The purpose of our study is to evaluate the quantitative and qualitative composition of the essential oil of Hyssopus seravschanicus (Dubj.) Pazij. (Lamiaceae) as a new plant species introduced in the conditions of the Right Bank Forest-Steppe Zone of Ukraine. Methods. To obtain the essential oil of H. seravschanicus, the method of hydrodistilla­tion using a Clevenger apparatus was applied. Air-dry raw material of plants – the above-ground herbaceous part collected in the phase of mass flowering of plants was studied. The determination of compounds and their relative participation in the composition of the essential oil was determined by the method of gas chromatography-mass spectrometry. Results. The seed population of H. seravschanicus introduced in the conditions of the Right Bank Forest Steppe of Ukraine is characterized by a high biosynthesis of essential oil with a yield rate of 0.72±0.04 %. 27 essential oil compounds have been identified, which by their chemical nature belong to terpenes, terpenoids and sesquiterpenes. The dominant compound is Isopinocamphone (61.58 %). An equally important role in the aromatic composition of the oil is played by β-Pinene (14.66 %), Terpinen-4-ol (8.53 %), Sabinen (2.24 %), 1.8-Cineol (1.77 %) and Myrcene (1.77 %), Spathulenol (1.5 %). Conclusions. Thus, the high essential oil productivity of the introduced species H. seravschanicus was experimentally established in new growth conditions – the Right-Bank part of the Forest-Steppe Zone of Ukraine. This allows us to consider this type of plant as a source of natural essential oils of the isopinocamphonic chemotype – H. seravschanicus st. Isopinocamphone.
