“…Preparation of a solution of GSO quercetin: about 0.05 g (accurately weighed) GSO quercetin, previously dried at a temperature of 130-135 °C for 3 hours, quantitatively transferred into a volumetric flask with a capacity of 50 cm 3 , dissolved in 40 ml of 96 % aqueous alcohol when heated on the water bath. After dissolution, the contents of the flask are cooled to room temperature and brought to the mark with 96 % alcohol.…”

“…Essential oils and alcoholic extracts of poplar buds have pronounced antimicrobial properties superior to propolis extract and even eucalyptus oil [2]. According to traditional medicine recipes, they have long been used to treat bronchitis, tuberculosis, and rheumatism as a wound healing and anti-inflammatory agent [3]. Recently, the effect of plant substances on the growth characteristics of filamentous and yeast fungi was studied [4,5].…”

Currently, natural plant extracts, which include biologically active substances, are increasingly used to produce medicines and cosmetics. In connection with the dangers of a radioecological crisis, special attention is paid to finding ways to protect against the effects of chronic exposure to low-intensity ionizing radiation in natural conditions. Currently, there is no ideal and safe radioprotective agent available, and we are seeing a great effort to find these agents from natural sources. Poplar extract is possible for use as a radioprotective shield from γ-radiation. Samples of protective screens were made from poplar extract on paper and showed a significant radioprotective effect. Phenolic compounds and flavonoids are widely present in plants as a second metabolite and are considered for research depending on their benefits for human health, healing and preventing many disorders. The main biologically active properties of flavonoids include antioxidant, anti-inflammatory, antitumor, rejuvenating, antibacterial and viral, neuroprotective and radioprotective action. The aim of this work was – the study of Flavonoids in an extract obtained from poplar buds and the possibility of their use for protection against radiation. Materials and methods. The object of research is the vegetative organs of poplar (buds). In the process of work, experimental studies were carried out on the extraction and separation of natural compounds, identification of flavonoids, and study of the chemical composition of biologically active complexes of poplar and preparations based on them. Research results. Data from these studies provide the identification of flavonoids by spectroscopy and quantification of flavonoids in poplar bud extract and can contribute to the optimization of radioprotection procedures. The main components found in the poplar buds dry extract are 2',6'-dihydroxy-4'-methoxychalcone – are 2',6'-dihydroxy-4'-methoxychalcone – 2,67 %, 3,4-dihydro-2',6'-dihydroxy-4'-methoxychalcone – 2,33 %, pinobaxin -1,91 %, chrysin – 0,76 %, pinostrobin – 0,04 %, pinocembrin – 0,61 %, tectochrysin- 0,54 % and galangin – 0,18 % of dry material. The results showed that the power of the penetrating radiation decreases with increasing the thickness of the protective screen. The power of penetrating radiation decreased from 78 % at the layer of 0.5 mm to 10 % at 3 mm layer thickness. Further increasing the thickness of the protective screen (> 3 mm), doesn’t affect the dose rate. Conclusions. The composition of the poplar buds' ethanol extract was investigated. Samples of protective screens made on the basis of poplar extract on paper showed a significant radioprotective effect on low-intensity ionizing radiation

In recent years, there has been a persistent search for new methods and technologies for cultivating specific crops to increase their productivity and improve product quality. The aim of the study was to obtain essential oil from poplar buds by the barothermal method, to standardize the obtained essential oil, to study the effect of an aqueous emulsion of poplar oil on the growth and development of tomato seeds. For obtaining the maximum yield of balsam poplar essential oil, the optimum pressure, input of raw material, and processing time were investigated. The essential poplar oil was standardized according to organoleptic and physico-chemical parameters. The study found that the use of an aqueous emulsion of poplar bud oil had a significant impact on the morphogenesis, physiological and biochemical parameters of tomato seeds.
