Common myrtle (Myrtus communis L.) is widely distributed and contains an essential oil. The component composition of the essential oil was studied by gas-liquid chromatography from the leaves of M. communis grown in Apsheron, in the collections of the Institute of Dendrology. The essential oil is a light yellow liquid. The content of essential oil in the leaves was 0.3-0.4 %. 26 components were identified, the main ones are α-pinenes (27,2 %), 1,8-cineol (26,4 %) and myrtenyl acetate (15,2 %).
