“…We investigate dynamic properties of mechanically clamped GPI crystal in the presence of the electric fields on the basis of dynamic model, which is grounded on the ideas of stochastic Glauber model [3]. On the basis of methods, developed in [4,5], we obtain such system of equations отримуємо for timedependent distribution functions of protons…”

Dynamic model of deformed quasi-one-dimensional ferroelectrics with hydrogen bonds is proposed. On the basis of this model within the two-particle cluster approximation with taking into account short-range and long-range interactions and strains εi and ε5 in the frames of Glauber method a dynamic dielectric permittivity of mechanically clamped crystal is calculated. Hydrostatic pressure effect on temperature and frequency dependences of the components of dynamic dielectric permittivity tensor of GPI ferroelectric is investigated.

Lemna Minor L. (LM) is a perennial aquatic plant that belongs to the genus Lemna, the family Lemnaceae and is spread almost ubiquitously. In folk medicine, it is used in the treatment of allergies, asthma, vitiligo, jaundice, glaucoma, rheumatism, gout, and others. In recent years it has become clear that its chemical composition consists of: proteins (up to 35%), vegetable fibers (up to 17%), fats (up to 5%), polysaccharides, flavonoids, amino acids, aliphatic acids, phenolic acids, triterpene compounds, vitamins, micro- and macro-elements and other substances. А significant part of these substances exhibit the antioxidant activity. The scientific information for 12 biologically active substances with antioxidant activity isolated from Lemna Minor is presented in the review.

The relevance of the study is conditioned by the need to optimise the production process of the sunflower farming ecosystem by increasing environmental sustainability. Among the by-products of processing, the use of which is still not effective, the release of the powerful antioxidant chlorogenic acid has not been sufficiently studied. In this regard, this paper is aimed at revealing the patterns of accumulation and identification of phenolic compounds in cotyledons and sunflower husks. The purpose of the study is to identify phenolic compounds in cotyledonous leaves and husks of various genotypes of common sunflower (Helianthus annuus L.) by thin-layer chromatography. In the course of research on this problem, the authors used field, biochemical, and statistical research methods. To identify chlorogenic acid, a solvent system was used: chloroform – glacial acetic acid – methanol – water (60:32:12:8). Chromatography analysis was performed in the SORBFLIL TLC software suite. The object of research is the Auris common sunflower hybrid. It is established that the qualitative composition of the phenolic complex and the number of individual compounds has a pronounced variety specificity. On the chromatogram, this substance has an Rf of ~ 0.60 (for sunflower husks) and an Rf of ~0.74 (for cotyledonous leaves). It was found that the most effective solvent for chlorogenic acid is aqueous ethanol. Extraction of chlorogenic acid with 40% ethanol provides up to 10 mg/g of chlorogenic acid. In addition to chlorogenic acid, a small amount of caffeic acid was found in the alcohol extract. The materials of the study are of practical value for improving the processes related to the development of the productivity of sunflower crops and the rational use of processing by-products
