Глубокие эвтектические растворители [ГЭР, deep eutectic solvents (DESs)] сегодня являются объектом пристального внимания научного сообщества различных областей, таких как химия, биология, фармация, биотехнология. Сферы применения ГЭР широко варьируют, и одной из них является извлечение биологически активных веществ из растительного сырья.</p></sec><sec><title>Цель</title><p>Цель. Целью настоящей работы было изучить возможность экстракции флавоноидов из растительного сырья посредством глубоких эвтектических растворителей на основе холина хлорида, а также сопоставить эффективность их экстракции с традиционными растворителями.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Экстракцию флавоноидов проводили из сбора растительной композиции, состоящей из травы пустырника сердечного (пустырника обыкновенного) (Leonurus cardiaca L.), травы зверобоя продырявленного (Hypericum perforatum L.), травы мелиссы лекарственной (Melissa officinalis L.) и травы тимьяна ползучего (чабреца) (Thymus serpyllum L.) в соотношении 4 : 2,5 : 2,5 : 1, измельченных до размера частиц 2–3 мм. В качестве экстрагентов использовались ГЭР на основе холина хлорида в качестве акцептора водородной связи.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. В данной работе были исследованы ГЭР на основе холина хлорида на предмет способности к извлечению флавоноидов из лекарственного сбора растительной композиции на основе травы пустырника, травы зверобоя, травы мелиссы и травы чабреца, обладающей седативным действием. Также было изучено влияние содержания воды в составе ГЭР на свойства экстрагента. Количественное определение флавоноидов в пересчете на рутин проводилось методом дифференциальной спектрофотометрии при длине волны 410 ± 2 нм. Максимальный выход флавоноидов был достигнут при использовании 50%-го водного раствора ГЭР на основе холина хлорида, глюкозы и воды в мольном соотношении 2 : 1 : 1 при температуре экстракции 60 °С.</p></sec><sec><title>Заключение</title><p>Заключение. Извлекающая способность полученного ГЭР по эффективности экстракции флавоноидов превышает экстрагирующие характеристики классического экстрагента для исследуемой композиции – 70%-го этилового спирта. Дальнейшее изучение свойств полученного экстрагента, его физических, химических, токсикологических характеристик – задача будущих экспериментов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Nowadays deep eutectic solvents (DESs) are the object of close attention of the scientific community in various fields, such as chemistry, biology, pharmacy, biotechnology. The areas of application of DESs vary widely, and one of them is the extraction of biologically active substances from plant raw materials.</p></sec><sec><title>Aim</title><p>Aim. The aim of this work was to study the possibility of extraction of flavonoids from plant raw materials with using of deep eutectic solvents based on choline chloride, as well as to compare the efficiency of their extraction with traditional solvents.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The extraction of flavonoids was carried out from the collection of a plant composition consisting of the herb of motherwort cordial (common motherwort) (Leonurus cardiaca L.), the herb of St. John's wort (Hypericum perforatum L.), the herb of lemon balm (Melissa officinalis L.) and the herb of creeping thyme (thyme) (Thymus serpyllum L.) in a ratio of 4 : 2.5 : 2.5 : 1, crushed to a particle size of 2–3 mm. DESs based on choline chloride as hydrogen bond acceptor were used as extractants.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. In this article, DESs based on choline chloride were investigated for the ability to extract flavonoids from the medicinal collection of a plant composition based on leonurus grass, hypericum grass, melissa grass and thyme grass, which has a sedative effect. The influence of the water content in DES solutions on the properties of the extractant was also studied. Quantitative determination of flavonoids in terms of rutin was carried out by differential spectrophotometry at a wavelength of 410 ± 2 nm. The maximum yield of flavonoids was achieved by using a 50 % aqueous solution of DES based on choline chloride, glucose and water in a molar ratio of 2 : 1 : 1 at an extraction temperature of 60 °C.</p></sec><sec><title>Conclusion</title><p>Conclusion. The extracting ability of the obtained DES in terms of the efficiency of flavonoid extraction exceeds the extracting characteristics of the classical extractant for the composition under study – 70 % ethanol. Further study of the properties of the obtained extractant, its physical, chemical, and toxicological characteristics is the task of future experiments.  </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>глубокие эвтектические растворители (ГЭР)</kwd><kwd>флавоноиды</kwd><kwd>дифференциальная спектрофотометрия</kwd><kwd>пустырник</kwd><kwd>зверобой</kwd><kwd>мелисса</kwd><kwd>чабрец</kwd><kwd>холина хлорид</kwd></kwd-group><kwd-group xml:lang="en"><kwd>deep eutectic solvents (DESs)</kwd><kwd>flavonoids</kwd><kwd>differential spectrophotometry</kwd><kwd>motherwort</kwd><kwd>John's wort</kwd><kwd>lemon balm</kwd><kwd>thyme</kwd><kwd>choline chloride</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">Abubakar A.
