В ряде исследований показано, что различные генетические факторы и факторы окружающей среды могут влиять на биосинтез и накопление вторичных метаболитов. В частности, известно, что местный геоклимат и сезонные его изменения, прочие внешние условия, такие как свет, температура, влажность и химический состав почвы оказывают влияние на химический состав и, как следствие, на терапевтические свойства экстрактивных комплексов растений, используемых в медицинской практике. Empetrum nigrum L. (водяника чёрная) является источником разнообразных фармакологически активных вторичных метаболитов – халконов, дигидрохалконов, бибензилов, 9,10-дигидрофенантренов, флавоноидов, а также проантоцианидинов. В научной литературе отсутствуют данные о вариации химического состава E. nigrum в зависимости от регион произрастания. Полученные данные являются необходимыми для обоснованного выбора места заготовки объекта с целью проведения дальнейших химико-фармакологических исследований для разработки перспективных лекарственных кандидатов.</p></sec><sec><title>Цель</title><p>Цель. Провести сравнительный анализ состава вторичных метаболитов образцов надземной части E. nigrum, собранных в различных регионах Российской Федерации.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Для изучения состава вторичных метаболитов использовали образцы, собранные в трех различных географических точках: образец 1 собран в окрестностях питомника лекарственных растений СПХФУ (Ленинградская область, Всеволожский район, Приозерское шоссе, 38 км) в июле 2020 года, образец 2 собран на Кольском полуострове, в районе горного массива Хибины в июле 2020 года, образец 3 собран на полуострове Камчатка, в районе Халактырского пляжа (побережье Тихого Океана) в июле 2020 года. Установление состава вторичных метаболитов проводили методом аналитической высокоэффективной жидкостной хроматографии (ВЭЖХ) на приборе Prominence LC-20 (Shimadzu, Япония), оснащенном диодно-матричным детектором.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. В результате данного исследования впервые были установлены значительные вариации качественного химического состава образцов надземной части E. nigrum, произрастающих в различных регионах Российской Федерации. Образец 3, собранный на полуострове Камчатка, по сравнению с прочими образцами содержит наибольшее разнообразие полярных вторичных метаболитов, относящихся к классам флановоидов, танинов и фенолкарбоновых кислот, в то время как в образце 1, собранном в Ленинградской области, мажорными соединениями являются слабополярные соединения, а в образце 2, собранном в горном массиве Хибины, обнаружено наименьшее качественное содержание вторичных метаболитов. Данная вариабельность химического состава могут быть обусловлены различным воздействием факторов окружающей среды (биотическими и абиотическими).</p></sec><sec><title>Заключение</title><p>Заключение. Впервые проведено сравнение ВЭЖХ-профилей образцов надземной части E. nigrum, собранных в различных регионах РФ. В результате установлена значительная вариация состава вторичных метаболитов в исследуемых образцах в зависимости от места и условий произрастания. Полученные данные могут быть использованы для обоснованного выбора места заготовки объекта с целью проведения дальнейших химико-фармакологических исследований для разработки перспективных лекарственных кандидатов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. A number of studies have shown that various genetic and environmental factors can affect the biosynthesis and accumulation of secondary metabolites. In particular, it is known that the local geoclimate, seasonal changes, external conditions such as light, temperature, moisture and soil fertility can affect the chemical composition and, as a result, the therapeutic properties of plants used in the pharmaceutical and food industries. Empetrum nigrum L. is a rich source of various pharmacologically active secondary metabolites – chalcones, dihydrochalcones, bibenzyls, 9,10-dihydrophenanthrenes, flavonoids, and proanthocyanidins. In the scientific literature, there is no data on the variation in the chemical composition of E. nigrum depending on the growing area. The obtained data are necessary for a reasonable choice of the collecting location for the plant, with the aim of its further chemical and pharmacological research for the development of promising drug candidates.</p></sec><sec><title>Aim</title><p>Aim. To carry out a comparative analysis of secondary metabolites composition in the aerial parts of Empetrum nigrum growing in different regions of the Russian Federation.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Samples collected in three different areas were used to compare HPLC profiles: sample 1 was collected next to SPCPU nursery garden of medicinal plants (Leningrad region, Vsevolozhsky district, Priozerskoe highway, 38 km) in July 2020, sample 2 was collected on the Kola Peninsula, around the Khibiny mountains in July 2020, sample 3 was collected on the Kamchatka Peninsula, next to Khalaktyrsky beach (Pacific Ocean coast) in July 2020. Extracts were analyzed by analytical high performance liquid chromatography (HPLC) using a Prominence LC-20 device (Shimadzu, Japan) equipped with a diode array detector.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. As a result of the research, for the first time, a significant variation in the qualitative chemical composition in the aerial parts of Empetrum nigrum growing in different regions of Russian Federation was established. Sample 3, collected on the Kamchatka Peninsula, in comparison with samples 1 and 2, contain the greatest variety of polar secondary metabolites belonging to the classes of flavonoids, tannins, and phenol carboxylic acids, while in the shoots collected in the Leningrad region, the major metabolites were weakly polar compounds belonging to the classes of chalcones, dihydrochalcones, bibenzyls, and 9,10-dihydrophenanthrenes, and in sample 2, collected in the Khibiny mountains, the lowest qualitative content of secondary metabolites was found. This variation may be caused by various environmental factors (biotic and abiotic).</p></sec><sec><title>Conclusion</title><p>Conclusion. For the first time, the comparison of HPLC profiles of aerial part samples of E. nigrum, collected in different regions of the Russia Federation has been carried out. As a result, significant variations in the secondary metabolites composition of the studied samples were established, depending on the regions and growing conditions of the plants. The data obtained can be used for a reasonable choice of the collection location for the plant, with the aim of its further chemical and pharmacological research for the development of promising drug candidates.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Empetrum nigrum</kwd><kwd>водяника черная</kwd><kwd>ВЭЖХ-профайлинг</kwd><kwd>9</kwd><kwd>10-дигидрофенантрены</kwd><kwd>бибензилы</kwd><kwd>халконы</kwd><kwd>дигидрохалконы</kwd><kwd>флавоноиды</kwd><kwd>вторичные метаболиты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>black crowberry</kwd><kwd>Empetrum nigrum</kwd><kwd>HPLC-profiling</kwd><kwd>9</kwd><kwd>10-dihydrophenanthrene</kwd><kwd>bibenzyls</kwd><kwd>chalcones</kwd><kwd>dihydrochalcones</kwd><kwd>flavonoids</kwd><kwd>secondary metabolites</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Результаты работы получены с использованием оборудования ЦКП «Аналитический центр ФГБОУ ВО СПХФУ Минздрава России» в рамках соглашения № 075-15-2021-685 от 26 июля 2021 года при финансовой поддержке Минобрнауки России</funding-statement><funding-statement xml:lang="en">Research results were obtained using the equipment of the Center for Collective Use "Analytical Center of Saint-Petersburg State Chemical and Pharmaceutical University" within the framework of agreement No. 075-15-2021-685 dated July 26, 2021 with the financial support of the Ministry of Education and Science 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">Сокуренко М.
