COMPOSITION OF ESSENTIAL OILS OF SAGE SALVIA SCLAREA L. AND THEIR CHANGES DEPENDING ON THE VEGETATIVE PHASES OF DEVELOPMENT

The identification of substances and the determination of the quantitative content of the individual components in the essential oil were carried out using gas-liquid chromatography and gas chromatography-mass spectrometry methods. In the composition of essential oils from various organs of Salvia sclarea L. growing in the south of Uzbekistan, it was found: 11 leaves, 25 inflorescences, 21 flowers and 19 cups of components, the main components of which are linalool (38% in leaves, 19 inflorescences -44%, in flowers-27% and in cups-18-32%) and linalyl acetate (in leaves-3.6%, in inflorescences-34.0-28.0%, in flowers-37.0% and in cups-40.0%). Also, the constant components are geranyl acetate (2.7–7.2%), karyofillen (0.3–14%), and α-terpineol (5.7– 12.0%). Changes in the composition of essential oils from sage nutmeg blossoms are observed, depending on the vegetative phases of development. The largest amount of linalool (34%) in essential oils was observed during the period of mass flowering, in the further development of the plant, until drying, a decrease in the amount of linalool (up to 20%) was observed. There is also a decrease in the quantitative content of geranyl acetate (up to 2.7%) and α-terpineol (up to 5.7%). In contrast, the quantitative content of linalyl acetate increases (from 25% to 47%).
