Study of the component composition of Anthemis cotula L. extract and essential oil

Summary

The article considers the issues of studying the component composition of the ethanol extract and essential oil of Anthemis cotula L. (Asteraceae family) – Stinking chamomile. The plant material was collected during the mass flowering phase in the garden plots of the villages of Shahnazarli, Mollakamilli, Tazakend, Gandob of Shabran district and the outskirts of Gusar district. To study the chemical composition of the A. cotula extract, 40 grams of the above-ground part of the plant material were extracted with 95% alcohol. A total of 5 grams of extractive substances were obtained, which is 12,5% yield. The essential oil was obtained by hydrodistillation. 0,012% of essential oil was found in the aboveground part, 0,05% in the flowers. The component composition of the ethanol extract and essential oil was studied by chromatography-mass spectroscopy. 30 components (100%) were identified in the ethanol extract of A. cotula. The main ones are N'-[1-[4-chlorophenyl]-1H-tetrazol5-yl]-N,Ndiethyl-1,2-ethanediamine – 18,01; o-(n-nonyl) S-(2- diethylaminoethyl) ethylphosphonothiolate – 12,72%; D-galactose – 6,68%; Inositol, 1-deoxy – 8,76%; 1H-imidazole-2-amine – 7,79%; A' –Neogammacer22(29)-en-3-ol, acetate, (3β, 21β) – 6,39%. In the essential oil obtained from the flowers of A. cotula, 5 (100%) components were identified. The dominant component of the essential oil is 2,3-butanediol (53%).
