Abstract. In this work, the biochemical parameters of the leaves of Allium L. species cultivated for food, 11 subgenera and 22 sections, were evaluated. In total, 36 samples from the bio-collection of the All-Russian Scientific Research Institute of Vegetable Production (Moscow Region) were investigated. Experiments were conducted during the 2016–2017 period. The soil in the experimental plot was presented by alluvial meadow, with the pH of the salt solution and the humus content in the topsoil ranging from 5.8 to 6.0 and from 2.71 to 3.34%, respectively. Leaf samples were collected in the morning during the vegetative phase (in May) from adult generative plants, which had been growing for 3–4 years under the conditions of introduction. The experiments were repeated three times. In the group of the onion cultures studied, the content of dry substances ranged from 8.6 (A. leucocephalum) to 19.3 (A. narcissiflorum), averaging 23.6 ± 2.9%; the content of nitrates ranged from 110 (A. ramosum) to 256 (A. tuberosum), averaging 175.3 ± 37.5 mg/kg of wet weight; the content of monosaccharides ranged from 2.6 (A. oschaninii, A. condensatum, A. altyncolicum, A. ledebourianum) to 4.2 (A. ascalonicum, A. ramosum, A. cyrilli), averaging 3.3 ± 0.6% of wet weight. The concentration of ascorbic acid varied from 119.2 (A. pskemense) to 133.5 (A. suworowii), averaging 126.0 ± 4.1 mg% of wet weight; chlorophyll – from 138 (A. pskemense) to 289 (A. gultschense, A. ascalonicum) mg/100 g of dry weight, averaging 219.1 ± 46.8 mg%; carotene – from 14.5 (A. pskemense) to 33.1 (A. barsczewskii), averaging 24.2 ± 4.9 mg/kg of wet weight. The content of hydroxycinnamic acids ranged from 169.8*10E-3 (A. oliganthum) to 185.0*10E-3 (A. sewerzowii), averaging 174.4 ± 3.9*10E-3% of dry weight; flavonoids – from 289.8*10E-3 (A. oliganthum) to 311.3*10E-3 (A. sewerzowii), averaging 296.0 ± 5.0*10E-3% of dry weight. A conclusion is made that the studied Allium L. species can be considered as a potential source of biologically active compounds.
