Известно, что растения Rhamnus cathartica L. содержат широкий спектр вторичных метаболитов, обладающих фармакологическим действием. Выбраны постоянные пробные площадки произрастания R. сathartica – аборигенного для Беларуси (2 площадки) и инвазионного в США вида (2 площадки). В данной работе был исследован уровень содержания антрахинонов (гидроксиантраценпроизводных), катехинов и лейкоантоцианов, а также проведена идентификация антрахинонов методом высокоэффективной жидкостной хроматографии (ВЭЖХ) с масс-спектрометрическим и УФ-детектором, показано значительное варьирование этих показателей в зависимости от условий и ареала. Выявлены хеморасы Rhamnus cathartica, что позволит в дальнейшем отбирать образцы с требуемым набором фенольных соединений и проводить направленную селекцию на получение искусственных интродукционных популяций с повышенным содержанием того или иного ценного соединения.</p></abstract><trans-abstract xml:lang="en"><p>The European buckthorn (Rhamnus cathartica L.) – a shrub native to most parts of Europe and Western Asia – has been successfully naturalized in the Midwest and Northeast of the USA, dominating various habitats and displacing native species. It is known that Rhamnus cathartica L. plants contain a wide range of secondary metabolites with pharmacological effects. Permanent sample plots with R. cathartica – the species native for Belarus (two sites) and invasive in the USA (two sites) – were selected. This study investigated the level of anthraquinones, catechins, and leucoanthocyanins, and identified anthraquinones using HPLC with mass spectrometry and UV detection, showing a significant variation in these indicators depending on the conditions and the geographical area of growth. Rhamnus cathartica chemorases were identified, which will allow further isolation of samples with a required set of phenolic compounds and a directed selection for obtaining artificially introduced populations with an increased content of one or another valuable compound.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>жостер слабительный (Rhamnus cathartica L.)</kwd><kwd>Беларусь</kwd><kwd>регионы Среднего Запада</kwd><kwd>США</kwd><kwd>глюкофрангулины</kwd><kwd>метод ВЭЖХ с масс-спектрометрическим и УФ-детектором</kwd><kwd>катехины</kwd><kwd>лейкоантоцианы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>European buckthorn (Rhamnus cathartica L.)</kwd><kwd>Belarus</kwd><kwd>regions of the Upper Midwest</kwd><kwd>USA</kwd><kwd>anthraquinones</kwd><kwd>HPLC method with mass spectrometric and UV detector</kwd><kwd>catechins</kwd><kwd>leukoanthocyanins</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках ГПНИ «Природные ресурсы и окружающая среда», задания 6.2, при поддержке комиссии по инвазионным видам Научного совета ботанических садов стран СНГ при МААН, программы ГБС РАН 122042600141-3.
