The component composition of the essential oil isolated by hydrodistillation from the leaves and flower petals of Prunus cerasus from two places of growth in the Ferghana region: Tashlak and Altiaryk districts has been studied. Chromatography-mass spectral analysis of essential oil was used to identify: for Tashlak samples – 48 compounds in flowers (sample 1), which is 92.89% of the total amount of oil, 59 substances (93.07%) in leaves (sample 2); for Altiaryk samples – in flowers (sample 3) 33 compounds (88.05%), 57 compounds (79.44%) in leaves (sample 4). In the composition of the essential oil of sample 1, the predominant components are 4-ethenyl-2-methoxyphenol – 27.75%, 4-vinylphenol – 17.86%, furfural – 9.23%, 5-methylfurfural – 7.69%, 2-acetylpyrrol – 4.52%, furfuryl alcohol – 2.15%, Nonanoic acid – 1.86%. In sample 2, the following predominate: herniarin (7-methoxycoumarin) – 38.06%, coumarin – 28.53%, eugenol – 4.74%, hexadecanoic acid – 2.53%. In sample 3 – the highest content: 4-ethenyl-2-methoxyphenol – 17.90%, 4-vinylphenol – 16.59%, isomeric lilac alcohols: lilac alcohol D – 9.05%, lilac alcohol C – 8.79%, lilac alcohol B – 1.42%, tricosane – 4.25%, nonanoic acid – 3.88%, nonanol – 1.97%, estragole – 3.86%. Sample 4 mainly contains: herniarin – 29.39%, coumarin – 10.04%, eugenol – 6.56%, dihydrocoumarin – 5.04, hexadecanoic acid – 4.13%, terpinolene – 3.52%, phytol – 3.41%. The observed significant differences between the studied samples, as well as with related samples from other habitats, are discussed.
