Для анализа использовали соцветия календулы. Растения выращивали на экспериментальном участке отдела биохимии и биотехнологии растений Центрального ботанического сада НАН Беларуси. Соцветия сорта «Махровый 2000» собирали в июле 2013–2016 гг., остальных сортов – в 2016 г. Сырье высушивали до воздушно-сухого состояния и хранили в темноте, а затем измельчали в агатовой ступке либо в кофемолке. Экстракцию осуществляли дистиллированной и дейтерированной водой (D2O) в соотношении расти-тельное сырье : экстрагент = 1:15. В результате установлены качественный и количественный составы водных экстрактов изучаемых сортов. В исследованных образцах обнаружено 11 аминокислот: аланин, γ-аминомасляная кислота, аспарагин, валин, глутамин, изолейцин, лейцин, пролин, тирозин, треонин и фенилаланин, среди которых преоблада-ли аспарагин и пролин. Кроме того, определены моносахариды: 2 изоформы глюкозы и 3 изоформы фруктозы. Анализ спектров на ядрах 31Р показал, что в водном экстракте цветков календулы в заметных количествах присутствуют и фосфаты. Показано, что сорта календулы «Гейша», «Махровый 2000», «Принц Индии» имели сходный качественный и количественный составы углеводов и сахаров. Спектрально отличались экстракты сорта «Дракон», в пуле аминокислот преобладал аспарагин, а содержание β-фруктопиранозы было понижено по сравнению с другими сортами.</p><sec><title> </title><p> </p></sec><sec><title> </title><p> </p></sec></abstract><trans-abstract xml:lang="en"><p>Using NMR analysis, the composition of the aqueous extracts of pot marigold inﬂorescence of cultivars “Geisha”, “Mahrovy 2000”, “Dragon”, “Prince of India” were investigated. Inﬂorescences of pot marigold were used for the analysis. Plants were grown in the experimental area of the Department of Biochemistry and Biotechnology of Plants of Central Botanical Garden of the NAS of Belarus. Inﬂorescence of “Mahrovy 2000” was collected in July 2013–2016, other varieties – in 2016. The raw materials were air dried and kept in the dark, then crushed in an agate mortar or in a coffee grinder. The extraction was performed with distilled and deuterated water (D2O) at a ratio of plant raw material : extractant = 1 : 15. As a result, the qualitative and quantitative composition of aqueous extracts of cultivars was determined. In the investigated samples 11 aminoacids: alanine, γ-aminobutyric acid, asparagine, valine, glutamine, isoleucine, leucine, proline, tyrosine, threonine and phenylalanine were determined, asparagine and proline prevailed. Monosaccharides, such as 2 isoforms of glucose and 3 isoforms of fructose, were determined as well. Analysis of the spectra on 31Р showed that phosphate is present in signiﬁcant amounts in the aqueous extract of pot marigold ﬂowers. “Geisha”, “Mahrovy 2000” and “Prince of India” varieties were shown to have similar qualitative and quantitative composition of carbohydrates and sugars. Spectrum of extracts of the variety “Dragon” was different from the others with the asparagine predomination in the pool of amino acids, and the content of β-fructopyranose lower in comparison with other varieties.</p><sec><title> </title><p> </p></sec><sec><title> </title><p> </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>соцветия календулы</kwd><kwd>водные экстракты</kwd><kwd>ЯМР анализ</kwd><kwd>аминокислоты</kwd><kwd>моносахариды</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pot marigold inﬂorescence</kwd><kwd>aqueous extracts</kwd><kwd>NMR analysis</kwd><kwd>aminoacids</kwd><kwd>monosaccharides</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">Muney, B.
