Сведения о сезонной вариабельности эфирных масел имеют ключевое значение при определении сезонов заготовки: вариации компонентного состава должны быть минимальны, а диапазоны концентраций должны соответствовать установленным в нормативной документации, при этом должен наблюдаться максимально возможный выход эфирного масла. Розмарин лекарственный произрастает на юге Российской Федерации (Республика Крым, Кавказ), при этом хроматографический профиль его эфирного масла не закреплен в нормативной документации, а в русскоязычной научной литературе отсутствуют исследования сезонных вариаций компонентного состава эфирного масла несмотря на то, что в Республике Дагестан розмарин лекарственный цветет практически круглогодично.</p></sec><sec><title>Цель</title><p>Цель. Изучение сезонных вариаций эфирного масла розмарина лекарственного дагестанского происхождения.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Оценка содержания эфирного масла проводилась в соответствии с требованиями Европейской фармакопеи 11 издания путем гидродистилляции с использованием аппарата Клевенджера. Газохроматографический анализ проводился с использованием газового хроматографа «Кристалл 5000.2», оснащенного пламенно-ионизационным детектором, разделение проводилось на колонках с неподвижной фазой различной полярности: HP-5MS UI и DB-WAX. Идентификация компонентов проводилась путем сравнения расчетных линейных индексов удерживания, полученных на двух колонках различной полярности, со справочными значениями.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Содержание эфирного масла розмарина лекарственного в растительном сырье составляет от 2,06 до 2,24 %. Статистический анализ не выявил значимых различий между результатами, полученными в течение эксперимента. По итогам газохроматографического анализа удалось установить α-пиненовый хемотип эфирного масла дагестанского происхождения. В образцах эфирных масел было идентифицировано 30 соединений, составляющих не менее 95 % от их состава. При интерпретации результатов статистической обработки содержания компонентов в зависимости от даты сбора сырья для большинства мажоритарных компонентов отмечены значимые различия.</p></sec><sec><title>Заключение</title><p>Заключение. В ходе исследования был впервые описан компонентный состав эфирного масла розмарина лекарственного (Salvia rosmarinus Spenn., seu Rosmarinus officinalis L.) дагестанского происхождения. Обнаруженные в ходе исследования статистически значимые различия содержания компонентов в зависимости от даты сбора растительного сырья могут быть использованы для хроматографического профилирования эфирного масла розмарина дагестанского происхождения. Такой подход позволит не только отразить географическую вариабельность компонентного состава, но и сезонную. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Information on the seasonal variability of essential oils has a key decision in determining the seasons of harvesting: the variation of component composition should be minimal, and the concentration ranges should correspond to those established in the regulatory documentation, while the maximum possible yield of essential oil should be observed. Rosemary grows in the south of the Russian Federation (the Republic of Crimea, the Caucasus) and the chromatographic profile of its essential oil is not fixed in the regulatory documentation, and in the Russian-language scientific literature there are no studies of seasonal variations in the component composition of essential oil, despite the fact that in the Republic of Dagestan rosemary blooms almost year-round.</p></sec><sec><title>Aim</title><p>Aim. Study of seasonal variations in the essential oil of the rosemary of Dagestan origin.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Estimation of essential oil content was carried out in accordance with the requirements of the European Pharmacopoeia 11th edition by hydrodistillation using a Clevenger apparatus. Gas chromatographic analysis was carried out using a gas chromatograph Crystal 5000.2 equipped with a flame ionization detector, separation was carried out on fixed phase columns of different polarity: HP-5MS UI and DB-WAX. The components were identified by comparing the calculated linear retention indices obtained on two columns of different polarity with reference values.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. The content of essential oil of rosemary in the plant raw material ranged from 2.06 to 2.24 %. Statistical analysis revealed no significant differences between the results obtained during the experiment. According to the results of gas chromatographic was able to establish α-pinene chemotype of essential oil of Dagestan origin. In the samples of essential oils 30 compounds were identified, constituting at least 95 % of their composition. When interpreting the results of statistical processing of the content of components depending on the date of collection of raw materials, significant differences were noted for the majority of major components.</p></sec><sec><title>Conclusion</title><p>Conclusion. The study was the first to describe the component composition of essential oil of rosemary (Salvia rosmarinus Spenn., seu Rosmarinus officinalis L.) of Dagestan origin. Detected during the study statistically significant differences in the content of components depending on the date of collection of plant raw materials can be used for chromatographic profiling of essential oil of rosemary of Dagestan origin. This approach will allow not only to reflect the geographical variability of the component composition, but also seasonal. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Salvia rosmarinus</kwd><kwd>розмарин лекарственный</kwd><kwd>эфирные масла</kwd><kwd>сезонная вариабельность</kwd><kwd>хроматографический профиль</kwd><kwd>газовая хроматография</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Salvia rosmarinus</kwd><kwd>rosemary</kwd><kwd>essential oils</kwd><kwd>seasonal variability</kwd><kwd>chromatographic profile</kwd><kwd>gas chromatography</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Результаты работы получены с использованием оборудования ЦКП «Аналитический центр ФГБОУ ВО СПХФУ Минздрава России».</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The results of the work were obtained using the equipment of the Center for Collective Use "Analytical Center" of the Federal State Budgetary Educational University of Higher Education SPCPU of the Ministry of Health of Russia.</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">Aziz E., Batool R., Akhtar W., Shahzad T., Malik A., Shah M.
