Исследование направлено на подбор и оптимизацию хроматографических условий для эффективного разделения и идентификации данных флавоноидов, обладающих высокой биологической активностью, а также на поиск новых видов растительного сырья для фармацевтической отрасли Республики Беларусь. Совместное использование масс-спектрометрического и спектрофотометрического детектирования обеспечило высокую чувствительность и селективность при идентификации кемпферола и его гликозидов. Астрагалин в количестве более 2,20 мг/г а. с. с. содержится в экстрактах Asclepias incarnata L., Geranium pratense L. и Glycyrrhiza uralensis Fisch. ex DC. Идентифицированы также три гликозида кемпферола в составе Glycyrrhiza uralensis Fisch. ex DC. и Glycyrrhiza glabra L. и два гликозида – в составе Borago officinalis L. Проведенное исследование демонстрирует эффективность метода ВЭЖХ-МС для анализа флавоноидов в многокомпонентных растительных матрицах и может быть использовано для контроля качества растительного сырья и в фармакогнозии.</p></abstract><trans-abstract xml:lang="en"><p>The article presents the results of kaempferol and its glycosides identification in plant extracts using the method of high-performance chromatography-mass spectrometry (HPLC-MS). The study is focused on the selection and optimization of chromatographic conditions for efficient separation and identification of these flavonoids with high biological activity, as well as at searching for new types of plant raw materials for the pharmaceutical industry of the Republic of Belarus. The use of the mass-spectrometric and spectrophotometric detection ensured high sensitivity and selectivity in the identification of kaempferol and its glycosides. Astragalin in an amount of more than 2.20 mg/g of absolutely dry raw material is contained in the extracts of Asclepias incarnate L., Geranium pratense L. and Glycyrrhiza uralensis Fisch. ex DC. Three glycosides of kaempferol were also identified in Glycyrrhiza uralensis Fisch. and Glycyrrhiza glabra L. extracts, and two glycosides – in the extracts of Borago officinalis L. The conducted study demonstrates the efficiency of the HPLC-MS method for analyzing flavonoids in multicomponent plant matrices and can be used for the quality control of plant raw materials and in pharmacognosy.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кемпферол</kwd><kwd>астрагалин</kwd><kwd>гликозиды кемпферола</kwd><kwd>агликон</kwd><kwd>идентификация</kwd><kwd>ВЭЖХ-МС</kwd><kwd>растительные экстракты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>kaempferol</kwd><kwd>astragalin</kwd><kwd>kaempferol glycosides</kwd><kwd>aglycone</kwd><kwd>identification</kwd><kwd>HPLC-MS</kwd><kwd>plant extracts</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Astragalin: A bioactive phytochemical with potential therapeutic activities / A.
