Тип записи:Публикация, BIOLOGICAL FEATURES OF MEDICINAL PLANT ELAEAGNUS RHAMNOIDES GROWING AT SOUTH-EAST OF KAZAKHSTAN(2020-12-20); ; ; Nurgul MamytovaElaeagnus rhamnoides berries contain significant amounts of bioactive vitamins, lipids, carotenoids, and phenolic compounds. They are widely used as an ingredient in functional products, cosmetics, and pharmaceutical formulations to prevent and treat cardiovascular, stomach, skin, and liver diseases. Natural sea buckthorn populations are widespread in Kazakhstan. Data on phytochemical and diagnostic indicators are absent for E. rhamnoides growing in Kazakhstan. In this work, seaberry from Kazakhstan was surveyed for diagnostic indicators, lipophilic and hydrophilic compounds. Analyses were conducted for main diagnostic indicators of leaves and fruits by standard microtechniques; fatty acid profiles by gas-chromatography; β-carotene by HPLCPDA; vitamin C and B by capillary electrophoresis, and pectin substances by titration. The main diagnostic indicators of leaves were stomatal anomocytic complex; corymbose and stellate hairs; conductive bundle - closed collateral; fruits - secretory passages and conducting bundles of a spiral type in the pulp parenchyma, and a large amount of fatty oil and aleuron grains in the embryo. In the oil from berry pulp/peel, the dominating fatty acids were palmitoleic and palmitic (28.53 and 30.03 %, respectively). Sea buckthorn seed oil, with its high a-linolenic levels and a near 1:1 ratio of ω-6:ω-3 fatty acids, represented a very balanced source of polyunsaturated fatty acids for human health and nutrition. β-Carotene content was 7.75 mg per kg, pectin substances – 3.27 %. In addition, the berries were rich in vitamins B complex (0.0035-0.014 mg/100g) and vitamin C (0.21 mg/100g). This work constitutes the first approach on knowledge about the phytochemical profile of Elaeagnus rhamnoides fruits from Kazakhstan and provides arguments multiple using of E. rhamnoides, both for fresh consumption and for industrial preparations in the form of jams and related products (functional multivitamin food) as well as byproducts (seeds) as raw materials for the production of oils suitable to be marketed by the pharmaceutical, cosmetic and food industries.Цитирования (OpenAlex) 2Цитирования (OpenCitations) 1 - Некоторые метрики заблокированы вашиминастройками согласия
Тип записи:Публикация, SUBJECTIVE UNDERSTANDING OF THE STUDENT WHEN USING OPEN EDUCATIONAL RESOURCES(2019-03-20); ; ; The relevance of the study is determined by the fact that open educational resources carry the ability to overcome the basic methodological construct complicating the learning process among students and namely the use of international experience while learning and obtaining knowledge. This study shows the aspects of functioning open educational resources and their technological basis. The novelty of the work was the formation of a model for the use of open educational resources in training of specialized courses of the Department of applied chemistry. The authors showed that the effectiveness of open educational resources use depends directly on the share of online learning and technological isolation of subjects. In particular, not only learning processes in the implementation of the program in applied chemistry, but also other disciplines that require the exchange of experience between countries and the use of a wide range of technological equipment and online structure are considered. In particular, training on the example of databases, information networks, and other spatially distributed structures are considered too. The practical significance of the study is defined by the fact that the use of open educational resources will not only intensify the learning process at the university, but also to determine the possibility of integration into the world educational space.Цитирования (OpenAlex) 3Цитирования (OpenCitations) 2
