The content of essential oil of this species was assessed and the chemical composition of the essential oil was analysed by gas-chromatography coupled with mass spectrometry. A content of 0.09 0.1 % essential oil was established. The main compounds identified in T. comosus essential oil were: caryophyllene-oxide (54.82 %), camphene (10.73 %), β-bourbonene (5.90 %), eudesmol (3.65 %), α-pinene (3.67 %).
