Тип записи:Публикация, Anatomical, morphological and phytochemical properties of Aegopodium alpestre Ledeb.: a case study of Kazakhstan(Academic Press, 2020-09-10); ; ; ; Gulraikhan E. ZHANTEYEVAThis article deals with the phytochemical, morphological and anatomical investigation of ethanol-based extracts derived from the leaves and stems of the Aegopodium alpestre. The vegetative organs of A. alpestre were conserved according to Strasburger-Fleµming method using a 1:1:1 mixture of alcohol-glycerin-water. A total of 1200 ethanol-based extracts (2 from leaves and 2 from stem tissues per plant) were prepared using the Soxhlet extractor. All extracts were used to identify organic and inorganic compounds in the leaves and stems of the studied plant. Contents of biologically active substances, microelements, vitamins and amino acids were determined. This article is the first paper to display very high concentration and diversity of vitamins (6 types), micronutrients (5 types), and aminoacids (13 types) in the leaves and steams of A. alpestre. Findings conclude that identification of biologically active substances in the above the ground vegetative organs of A. alpestre may be a common practice in the future. Considering the study results, A. alpestre may be used as a medicinal plant on a large scale. For this, the cultivation practice needs to be scaled up.Цитирования (OpenAlex) 4Цитирования (OpenCitations) 3 - Некоторые метрики заблокированы вашиминастройками согласия
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, Comparative phytochemical and GC-MS analysis of leaves, stems, and roots of Euphorbia yaroslavii Poljakov.(Instituto Internacional de Ecologia (Brazil), 2026-01-01); ; ; Euphorbia yaroslavii Poljakov. is a rare plant species endemic to Kazakhstan whose phytochemical composition has remained largely unexplored. This study presents the first organ-specific phytochemical and GC-MS characterization of the leaves, stems, and roots of this species. Quantitative analyses indicated pronounced metabolic differentiation among plant organs. Roots were characterized by high contents of total phenolics (58.2 ± 2.5 mg GAE/g DW), coumarins (2.48%), and mineral components (total ash 13.22%), while leaves exhibited the highest tannin content (2.35%). The maximum flavonoid content was observed in roots (0.27%), whereas stems contained the highest level of ascorbic acid (0.70 mg/g DW). GC-MS profiling tentatively identified 68 compounds in leaf extracts, 65 in stem extracts, and 39 in root extracts. Root extracts were dominated by fatty acids and triterpenoid-sterol constituents, including octadecanoic acid (18.9%), hexadecanoic acid (17.5%), β-amyrin (5.2%), and lanosterol (4.9%). Overall, the results indicate organ-specific metabolic specialization in Euphorbia yaroslavii Poljakov. and provide a reliable phytochemical baseline for future bioactivity-oriented and conservation-related studies. - Некоторые метрики заблокированы вашиминастройками согласия
Тип записи:Публикация, ГЕНОМНАЯ ОЦЕНКА ГЕНЕТИЧЕСКОГО РАЗНООБРАЗИЯ ПОПУЛЯЦИЙ CALLIGONUM LEUCOCLADUM (SCHRENK) BUNGE ЛЕКАРСТВЕННОГО В ПУСТЫНЕ КЫЗЫЛКУМ C. LEUCOCLADUM(Astana International University, 2026-03-27); H. MorgılCalligonum leucocladum (Schrenk) Bunge - экологически важный пустынный кустарник, адаптированный к засушливым и полузасушливым условиям Центральной Азии. Эта работа впервые предлагает комплексную оценку генетического разнообразия, структуры популяции и фитохимической изменчивости вида с использованием генотипа SNP с высоким разрешением и хемометрического профиля. Было проанализировано 150 особей из трех географически разделенных популяций (P1, P2 и P3) пустыни Кызылкум и прилегающих регионов. Анализ распада связывающего равновесия (LD) показал, что популяция P3 характеризуется самым высоким уровнем рекомбинации (r2 резко падает на 10 кб), в то время как P2 демонстрирует сильную LD на больших расстояниях, что указывает на среднюю генетическую изоляцию. Базовый координатный анализ (PCoA) объяснил 76,55% общей генетической изменчивости и подтвердил фактическую дифференциацию P1, в то время как P2 и P3 показали генетическое родство. Анализ минимального связующего дерева (MST) дополнительно подтвердил эти закономерности. Фитохимический профиль впервые выявил популяционные различия в общих фенолах, флавоноидах и антиоксидантных способностях, которые соответствуют генетической структуре. Результаты показывают, что географическая изоляция, фрагментация среды обитания и экологический стресс способствуют расхождению популяций. Высокое генетическое и биохимическое разнообразие популяции P3 определяет ее как потенциальный резервуар адаптивных признаков. Эта работа является ценной основой для планирования природоохранных мероприятий и экологического восстановления пустынной флоры.
