Тип записи:Публикация, УТОЧНЕНИЕ ИЗМЕНЕНИЙ В ТАКСОНОМИИ НА ОСНОВЕ ФИТОХИМИИ ВИДОВ СЕМЕЙСТВА РОЗОЦВЕТНЫХ (ROSACEAE)(2021-03-22); ; The article lists the characteristics and phytochemistry of species belonging to relatives of rosaceae (Rosaceae) family, which relates to the specific taxonomy of the subspecies. Phytochemistry of seeds was studied by Prunus domestica L. and Armeniaca vulgaris L. As a result, it has been established that two types of seeds are identical to the types of microelements, vitamins and a number of fatty acids. If there were two separate species, it would not have formed sexually by sex. The mineral elements were determined by the atomic absorption spectroscopy (AAS) method. Atomic absorption spectroscopy (AAS) is a quantitative analysis method based on the properties of atoms - measured by the actual wave length. Detection of the tissues of the seeds that absorb the atoms was carried out by two atomic methods. - 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.
