(чабреца обыкновенного) при использовании разных методов дистилляции. Объектом исследования выбраны два образца чабреца - тимольного и линалоольного хемотипов . Эфирное масло получали из свежесобранного сырья (соцветия в фазу массового цветения) следующими методами: методом гидродистилляции на апаратах Клевенджера и методом паровой экстракции на установке по производству эфирного масла и полупродуктов «Альфа-Эфир Компакт». Компонентный состав летучих веществ определяли методом газовой хромато-масс-спектрометрии. В составе летучих соединений эфирного масла растений идентифицировано 29 компонентов для тимольного хемотипа, в составе линалоольного хемотипа - 18. Выявлено, что использование метода гидродистилации позволяет экстрагировать на 40-50% больше эфирного масла. Обнаружены существенные различия между массовой долей извлеченных компонентов эфирного масла при использовании различных методов и содержания массовой доли эфирного масла в сырье Th. vulgaris и установлено, что в зависимости от способа получения эфирного масла, меняется доля легколетучих терпеновых углеводородов и кислородсодержащих соединений. Метод паровой отгонки приводит к ухудшению компонентного состава эфирного масла, снижая содержание доминирующих компонентов обоих хемотипов (тимола и линалоола).</p></abstract><trans-abstract xml:lang="en"><p>The objective of the work was to identify changes in the amount and component composition of essential oil in the raw material of Thymus vulgaris L. (common thyme) when using different distillation methods. The object of the study was two samples of thyme-thymol and linalool chemotypes. Essential oil was obtained from freshly harvested raw materials (inflorescences in the mass flowering phase) by the following methods: hydrodistillation method on Clevenger apparatuses and steam extraction method on the installation for the production of essential oil and intermediates "Alpha-Ether Compact". The component composition of volatile substances was determined by gas chromatography-mass spectrometry. In the composition of volatile compounds of plant essential oil, 29 components for the thymol chemotype were identified, and 18 components for the linalool chemotype were identified. It was found that the use of the hydrodistillation method allows extracting 40-50% more essential oil. Significant differences were found between the mass fraction of extracted essential oil components using different methods and the content of the mass fraction of essential oil in the raw material of Th. vulgaris and found that depending on the method of obtaining essential oil, the proportion of volatile terpene hydrocarbons and oxygen-containing compounds changes. The method of steam distillation leads to a deterioration of the component composition of the essential oil, reducing the content of the dominant components of both chemotypes (thymol and linalool).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>тимольный хемотип</kwd><kwd>линалоольный хемотип</kwd><kwd>методы экстракции эфирного масла</kwd><kwd>терпеновые углеводороды</kwd><kwd>кислородсодержащие соединения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Thymus vulgaris L</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">Биохимические методы анализа эфирномасличных растений и эфирных масел / Под ред.
