In 2009 in IREMK lavender variety Seuthopolis was distilled under laboratory conditions and the variation of the basic oil components was traced during distillation. Gas chromatography analysis was performed of the individual oils and organoleptic assesment was made with the aim to use the oil in cosmetics and perfumery. It was established that linalylacetate increased for 15 minutes, then began to decline, hydrocarbons and 3-okatanon distilled in great quantity in the first 5 min and gradually reduced within one hour, terpineol-4 evenly distilled during the process as differences in the content of various fractions are not more than 10%. In relation to flavour the most suitable oils are separated within 30 min of the process.
