2015
The paper shows the results of studing chemical composition of the essential oils, which were obtained from the ground part of wild plants Lycopus europaeus L. and Lycopus exaltatus L. The samples of essential oil were obtained from the raw materials of Lycopus europaeus L. and Lycopus exaltatus L. in the grow and bloom period by steam distillation. These samples are an easily movable liquid of light yellow color. The runout of essential oil in the raw material of Lycopus exaltatus L. was 0,9% and 0,7%; in the raw material of Lycopus europaeus L. – 0,7% and 0,5% ( in terms of dry raw materials) in the grow and bloom period respectively. In the sample of essential oil of Lycopus europaeus L. was founded about 31 components by the method of gas chromatography-mass spectrometry. Among them are identified the following compounds: α-terpineol (9,06%), caryophyllene oxide (10,30%), methyl isoeugenol (9.43%). The main substances of the essential oil of Lycopus exaltatus L. are 2,4-decadienal (51,72%), 2,4-hexadiene-1-ol (5,05%), α-limonene diepoxide (1.61%) among 12 identified components.
