Основными подходами математического описания получаемых результатов, являются моделирование массопереноса в соответствии со вторым законом Фика с вычисление коэффициентов диффузии и аппроксимация кинетических зависимостей уравнениями кинетики псевдо-реакции второго порядка. Тимьян обыкновенный (Thymus vulgaris L.) – многолетний, эфиромасличный полукустарник, произрастающий по всему миру, является перспективным источником флавоноидов и полифенольных кислот, обуславливающих его терапевтические свойства. Целью работы являлось изучение кинетики ультразвуковой экстракции биологически активных соединений в водноспиртовой среде из надземной массы тимьяна. Экстракты получены методом ультразвуковой экстракции. Общее содержание полифенолов определялось по реакции с реактивом Фолина-Чокалтеу, флавоноидов – по реакции комплексообразования с хлоридом алюминия, содержание хлорогеновой, феруловой и бензойной кислот – методом ВЭЖХ. Экспериментальные данные аппроксимированы уравнением реакции второго порядка. Установлены кинетические параметры процесса извлечения целевых соединений. Результаты исследования могут быть использованы при оптимизации процессов ультразвуковой экстракции фитокомпонентов из сырья представителей рода Thymus L. и применены в фармацевтической, косметологической и пищевой промышленности.</p></abstract><trans-abstract xml:lang="en"><p>The study of the kinetics of the extraction process is extremely necessary in the technology of processing plant raw materials. The main approaches to the mathematical description of the results obtained are the modeling of mass transfer in accordance with Fick's second law with the calculation of diffusion coefficients and the approximation of kinetic dependencies by equations of the kinetics of a pseudo-reaction of the second order. Thyme (Thymus vulgaris L.) is a perennial, essential oil semi-shrub growing all over the world, is a promising source of flavonoids and polyphenolic acids, which determine its therapeutic properties. The aim of the work was to study the kinetics of ultrasonic extraction of biologically active compounds in an aqueous alcohol medium from the herb Thymus vulgaris L. Extracts were obtained by ultrasonic extraction. The total content of polyphenols was determined by reaction with Folin-Ciocalteau reagent, flavonoids by complexation reaction with aluminum chloride, the content of chlorogenic, ferulic and benzoic acids by HPLC method. The experimental data are approximated by a second-order reaction equation. The kinetic parameters of the extraction process of the target compounds have been established. The results of the study can be used to optimize the processes of ultrasonic extraction of phytocomponents from herbs of the genus Thymus L. and are used in the pharmaceutical, cosmetology and food industries.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Thymus vulgaris L.</kwd><kwd>ультразвуковая экстракция</kwd><kwd>кинетические параметры</kwd><kwd>флавоноиды</kwd><kwd>полифенольные кислоты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Thymus vulgaris L.</kwd><kwd>ultrasound-assisted extraction</kwd><kwd>kinetic parameters</kwd><kwd>flavonoids</kwd><kwd>polyphenolic acids</kwd><kwd>dry subtropics</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания ННЦ-НБС РАН № FNNS-2024-0009 и ФИЦ КНЦ РАН № FMEZ-2023-0012.</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">Бейдеман И.Н.
