Fedtsch. Материал собран в июне 2019 г. в природной популяции в Республике Таджикистан. Фенольные соединения изучены в водно-этанольных 40%-х экстрактах методом высокоэффективной жидкостной хроматографии (ВЭЖХ). Аналитическая ВЭЖХ-система состоит из жидкостного хроматографа Agilent 1200 (США) с диодно-матричным детектором, автосамплером и системой для сбора и обработки хроматографических данных ChemStation. В нативных экстрактах из соцветий обнаружено 15 соединений фенольной природы, из листьев – 11 веществ. Из них идентифицированы хлорогеновая и коричная кислоты, кверцетин, кемпферол, гиперозид, изокверцитрин, авикулярин и астрагалин. Хроматографические профили листьев и соцветий различаются. В соцветиях S. baldshuanica обнаружены изокверцитрин, авикулярин, кемпферол, которые отсутствуют в листьях. В соцветиях концентрация всех обнаруженных фенольных соединений выше, чем в листьях. Мажорным компонентом в соцветиях является астрагалин (3,16 мг/г), концентрация которого в 5 раз больше, чем в листьях (0,60 мг/г). Путем кислотного гидролиза соляной кислотой (1:1) водно-этанольных экстрактов из листьев и соцветий были получены агликоны флавоноидов. В гидролизатах экстрактов из листьев и соцветий S. baldshuanica обнаружено 3 флавонолагликона ‒ кверцетин, кемпферол и изорамнетин. При пересчете концентрации агликона на соответствующий гликозид выявлено, что в листьях и соцветиях преобладают гликозиды кверцетина (6,67 мг/г – в соцветиях, и 1,19 мг/г – в листьях). S. baldshuanica сильно отличается от других представителей растений рода Spiraea секции Calospira по хроматографическому профилю фенольных соединений из листьев. Это является дополнительным подтверждением выделения ее в отдельный ряд Decumbentes по морфологическим признакам.</p></abstract><trans-abstract xml:lang="en"><p>For the first time, the composition and content of phenolic compounds in the leaves and inflorescences of Spiraea baldshuanica B. Fedtsch. was investigated. Research material was collected in June 2019 from a natural population in the Republic of Tajikistan. Phenolic compounds were studied in 40% water- ethanol extracts by the method of high-performance liquid chromatography (HPLC). The analytical HPLC system used consisted of an Agilent 1200 (USA) liquid chromatograph equipped with a diode array detector, an autosampler and a ChemStation system for collecting and processing chromatographic data. 15 and 11 compounds of phenolic nature were found in native extracts from inflorescences and leaves, respectively. Among them, the following substances were identified: chlorogenic and cinnamic acids, quercetin, kaempferol, hyperoside, isoquercitrin, avicularin and astragalin. The chromatographic profiles of leaves and inflorescences were found to be different. Such substances as isoquercitrin, avicularin, kaempferol were discovered in the inflorescences of S. baldshuanica, rather than in its leaves. Compared to the leaves, the concentration of all detected phenolic compounds was higher in the inflorescences under study. The major component in the inflorescences was astragalin (3.16 mg/g), whereas its concentration in the leaves was 5 times lower (0.60 mg/g). Flavonoid aglycones were obtained from the water-ethanol extracts of the leaves and inflorescences under study by acid hydrolysis using hydrochloric acid (1:1). The hydrolysates of extracts from the leaves and inflorescences of S. baldshuanica were found to contain 3 flavonoid aglycones: quercetin, kaempferol and isorhamnetin. By recalculating the concentration of aglycone for the corresponding glycoside, it was determined that quercetin glycosides prevails: 6.67 mg/g – in the inflorescences and 1.19 mg/g – in the leaves. S. baldshuanica differs significantly from other representatives of the Spiraea genus, section Calospira, in terms of the chromatographic profile of phenolic compounds contained in the leaves. This information serves as an additional argument for differentiating S. baldshuanica as a separate series of the Decumbentes group by morphological signs.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Spiraea baldshuanica</kwd><kwd>флавоноиды</kwd><kwd>фенолкарбоновые кислоты</kwd><kwd>высокоэффективная жидкостная хроматография</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Spiraea baldshuanica</kwd><kwd>flavonoids</kwd><kwd>phenolic acids</kwd><kwd>high-performance liquid chromatography</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания Центрального сибирского ботанического сада СО РАН (проект № АААА-А21-121011290025-2, а также при финансовой поддержке гранта Президента РФ для молодых ученых – кандидатов наук (проект № МК-1045.2020.4).</funding-statement><funding-statement xml:lang="en">This work was carried out within the framework of the state assignment of the Central Siberian Botanical Garden of the Siberian Branch of the Russian Academy of Sciences (project No. АААА- А21-121011290025-2), as well as with the financial support of a grant of the President of the Russian Federation for young scientists - candidates of sciences (project No. MK-1045.2020.4).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Запрометов М.Н.
