“…The biochemical composition of both bulbs and green leaves varies in different development stages depending on the breed, environmental and agro-technical conditions of the plant growing (Ananyina, and Glukhova, 1988;Dudchenko, 2009;Kielak et al, 2006;Nemtinov et al, 2019).…”

The mineral composition of Allium cepa L. leaves was measured by using the scanning electron microscope of Japanese company JEOL, model JSM600LA with EDS system. 11collection samples of FRC “All-Russian Institute of Plants Genetic Resources named after N. I. Vavilov” and 4 samples of FSBSI “Research Institute of Agriculture of the Crimea” were studied. 12 main elements (in mass., %) contained in onion leaves were evaluated. The samples with the maximum macro- and micronutrient elements accumulation in the leaves used for the sourthern subspecies breeds and hybrids selection were revealed. These samples can be used to prevent the elements deficiency in the human body. The following samples number with a high accumulation of the elements in the leaves was revealed: K – nine (from 20.0 to 3.3 max %: B12132B, trimontzium, Rouge pale, Red Wetherstfield, Blood red flat, Valensiya, Tavricheskiy, Yaltinskiy lux, Yaltinskiy rubin), P – five (from 1.8 to 2.8 mass., %:B12132B, Mestniy, Valensiya, Yaltinskiy lux, Yaltinskiy rubin), Mg – one (2.23 mass., %: Rouge pale), Ca – nine (from 5.4 to 8.3 mass., %: Mestniy, Rouge pale, Mestniy, Red Wetherstfield, Blood red flat, Valensiya, Brown Beauty, Yaltinskiy lux and Yaltinskiy rubin), Fe – two (from 0.5 to 0.8 mass., %: B12132B, Tavricheskiy), S – seven (from 2.2 to 2.5 mass., %: B12132B, Mestniy, Red Wetherstfield, Tavricheskiy, Yaltinskiy lux, Yaltinskiy rubin, Yaltinskiy model No. 3), Na – two (from 1.3 to 1.5 mass., %: B12132B, Mestniy), Cl – five (from 4.0 to 7.0 mass., %: Mestniy, B12132B, Trimontzium, Red Wetherstfield, Yaltinskiy model No. 3), Cu – one (1.9 mass., %: Yaltinskiy model No. 5), Mo – eight (from 5.2 to 7.0 mass., %: Tavricheskiy, Yaltinskiy lux, Yaltinskiy rubin, Yaltinskiy model No. 3, Mestniy, Trimontzium, Red Wetherstfield, and B12132B), Zn – seven (from 0.5 to 4.97 mass., %: Yaltinskii model No. 3, Mestniy, B12132B, Rouge pale, Blood red flat, Brown Beauty, Yaltinskiy rubin) and Si – one (0.5 mass.%,%: Yaltinskiy lux). The order of the elements accumulation variation in the onion samples was distributed as follows: Zn > Fe > Si > Na > P > Cl > Mo > Mg > S > Ca > Cu > K.

Aim. To determine the total polyphenols and antioxidant capacity and their correlation with antimicrobial and fungicidal properties in some species of the genus Allium growing in Tajikistan.Materials and methods. The objects of the study were 15 kinds of the Amaryllidaceae family. Antibacterial onions were studied by the disk diffusion method against 4 types of microorganisms (test strains) and 1 type of yeast fungus. In the presence of total polyphenols, the content in μg of Gallic acid (GA) per ml of plant extract was measured. To determine the antioxidant activity, a solution of ABTS K2S2O8 was used. Trolox was used as a standard.Results. The maximum content of total polyphenols is characterized by ethanol extracts of A. Carolinianum, A. altaicum, A. elatum, A. oschaninii, A. ramosum, A. hymenorhisum. At the same time, their lowest amount was found in the bulbs of A. longicuspis. A. shoenoprasum, which is statistically signiﬁcantly lower than in all the above-listed species of this plant group. The extracts from the stems of A. carolinianum, A. elatum, and A. pamiricum had the highest antioxidant effect. There is a direct weak correlation between biologically active components with antimicrobial and fungicidal activity in A. oshaninii and A. suworowii, depending on the altitude gradient.Conclusions. The results allow suggesting that the above-ground and underground parts of some wild-growing endemic species of the genus Allium have different degrees of antioxidant activity due to total polyphenols. The content of total polyphenols and the antioxidant capacity of extracts obtained from various plants in different in large ranges. In some cases, there are direct correlations between the content of polyphenols, antioxidant properties, antimicrobial and fungal properties.
