This review presents data on the current propolis research in Russia. The chemical composition, color, aroma and appearance of propolis are influenced by natural and climatic factors, the collection region and the originality of the flora in the collection place. Within Russia, organoleptic, physicochemical and chemical properties of propolis vary considerably. The article provides information on methods for assessing its quality. Propolis is widely used in folk and alternative branches of medicine in Russia. Its antioxidant and antimicrobial properties, as well as the possibility of using extracts on its basis for gastric ulcer, diabetes, periodontitis, radiation disease, gynecological diseases, tuberculosis, anemia, myocardial ischemia and cerebral ischemia, have been established. Propolis is used in the food industry, cosmetology, agriculture and veterinary medicine.

Anethum graveolens L. (Dill) is an aromatic, medicinal, and food plant that is widely known in the world. This paper presents the results of the study of the essential oil of A. graveolens, which was cultivated in the Stavropol region (Russia, North Caucasus) to restore its growth. Herb of A. graveolens, variety “Scythian”, was collected in different fields of the limited company “Cossack agriculture “Staropavlovskoe”. The essential oil was obtained by Clevenger distillation. The chemical composition of the essential oils was studied by the GC/MS method. 25 compounds were detected in essential oil: carvone; 3.9-epoxy-1-p-menthene; ipsdienol; 2-hydroxycineol; allyl caprate; carveol; 6-camphenol; 5-isopropenyl-2-methyl-7-oxabicyclo [4.1.0] heptane-2-ol; piperitone oxide; 3-methyl-2-pent-2-enyl-cyclopent-2-enone; cis-p-mentha-2.8-dien-1-ol; 2-cyclol piperitone oxidehydroxy-3-methyl-6-(1- methyleth); limonene-6-ol, pivalate; isopulegol acetate; z-(13,14-epoxy) tetradec-11-en-1-ol acetate. The major component in the oil detected was arvone (36.9–44.5%). The obtained data confirmed the positive result of the cultivation of A.graveolens with the content of carvone in the essential oil of herbs comparable to the content of carvone in fruits.

Objective: analyze and evaluate scientific literature data on the need for the use of plant sterols and stanols for the treatment of hypercholesterolemia in order to reduce the risk of coronary heart disease. Materials and methods. The article summarizes the information of scientific publications in the journals of search systems PubMed, Scopus, Google Scholar, as well as library databases (eLibrary). Results. Phytosterols (phytosterols), phytostanols, are lipid-like compounds found in foods of plant origin. Their structure is similar to cholesterol and therefore they successfully compete with it for absorption in the intestine, thus reducing the flow of cholesterol into the bloodstream. As a result of this therapy for hypercholesterolemia, the risk of coronary heart disease is reduced. The factors influencing the efficacy of sterols/stanols and ways to improve therapy with their use are discussed in the review. The effect of stanols on the immune system is also presented. Conclusion. Food products enriched with sterols and stanols (yoghurt, kefir, milk, spreads, etc.) are promising tools in the complex of non-medicinal measures to reduce LDL cholesterol levels, an established risk factor for CHD, and their introduction into the diet will contribute to the prevention of CHD among the Russian population.
