Материалы и методы. В качестве объектов исследования взяты 6 опытных образцов прополиса из разных регионов России. Из опытных образцов готовили извлечения спиртом этиловым 80%-ным по традиционной схеме  изготовления настоек в соотношении 1:10. Полученные извлечения фильтровали и использовали для непосредственного анализа. Хроматографическое разделение спиртовых извлечений прополиса проводили на жидкостном хроматографе фирмы «Agilent Technologies 1200 Infinity», США. Детекцию проводили с помощью диодноатричного детектора Agilent 1200. Результаты и обсуждение. Используя обращенно-фазную высокоэффективную жидкостную хроматографию в градиентном режиме элюирования, удалось идентифицировать флавоны и флавонолы. Выявлено, что состав прополиса имеет стабильный состав флавонов и флавонолов, включающий такие компоненты как кверцетин, изорамнетин, 3,4’-диметоксикемпферол, рамнетин, пендулетин, кемпферол, рамноцитрин, галангин, кемпферид, хризин и метоксигалангин. Из найденных компонентов наибольшее содержание приходитсяна флавонолы, метоксильные производные кемпферола – рамноцитрин (22,0%) и кемферид (12,0%), из флавонов – хризин (16,0%). Методом внутренней нормализации рассчитан удельный вес каждого из компонентов внутриуказанной группы. Установлено, что около 84% всех флавонолов приходится на кемпферол и его метоксильные производные. Состав флавонов и флавонолов может варьировать в зависимости от образца. При этом во всех изученных объектах присутствовал кемпферол, тогда как в отдельных пробах прополиса отсутствовалиотдельные из идентифицированных компонентов. Предложена стандартизация прополиса методом высокоэффективной жидкостной хроматографии по содержанию флавоноидов в пересчёте на кемпферол, как стабильный, коммерчески наиболее доступный компонент прополиса. Используя абсолютную градуировку, определено количественное содержание кемпферола в опытных образцах прополиса, которое находилось в диапазоне 0,0141–0,0159%. Заключение. Результаты проведённых экспериментов позволяют рекомендовать проводить оценку качества прополиса по содержанию кемпферола в опытных образцах.</p></abstract><trans-abstract xml:lang="en"><p>The aim of the study. This article is dedicated to the comparative assessment of flavones and flavonols composition in various samples of propolis for providing the possibility of its standardization. Materials and methods. To carry out the research, 6 experimental samples of propolis were taken from different regions of Russia. Using those samples, we prepared the extracts with 80% ethanol according to traditional scheme of making tinctures in the ratio of 1:10. After that our extracts were filtered and used directly in the assessment. Chromatographic separation of spirit extracts of propolis was carried out on a liquid chromatograph of “Agilent Technologies 1200 Infinity”, USA. The detection was carried out on the basis of the diode array detector “Agilent 1200”. Results and discussion. Using the reversed-phase HPLC in gradient elution regime we managed to identify flavonols and flavones. It was found out that the composition of propolis has a stable composition of flavones and flavonols including quercetin, isoramnetin, 3,4’-dimethoxycempferol, ramnetin, penduletin, kaempferol, ramnocitrin, galangin, kaempherid, chrysin and methoxyhalangin. Among the identified components, the highest content is in flavonols, methoxyl derivatives ramnocitrin (22,0%), and kaempherid (12,0%); in flavones it is chrysin(16,0%). The specific gravity of each component within the specified group was calculated by the internal normalization method. It was established that about 84% of all flavonols are in kaempferol and its methoxyl derivatives. The composition of flavones and flavonols can vary depending on the sample. Hereby, kempferol was identified in all the studied samples, whereas some of the identified components were absent from separate propolis samples. Propolis standardization by method of high-performance liquid chromatography in respect of the content of flavonoids in terms of kaempferol as a stable, commercially most available component of propolis was suggested. With the use of absolute calibration, the quantitative content of kaempferol in propolis samples wasdetermined in the range of 0.0141-0.0159%. Conclusion. The results of the carried out experiments made it possible to recommend the quality assessment of propolis according to the content of kaempferol in the experimental samples.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>прополис</kwd><kwd>флавонолы</kwd><kwd>обращенно-фазная высокоэффективная жидкостная хроматография</kwd><kwd>метод абсолютной градуировки</kwd></kwd-group><kwd-group xml:lang="en"><kwd>propolis</kwd><kwd>flavonols</kwd><kwd>reversed-phase high-performance liquid chromatography</kwd><kwd>absolute calibration method</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">Ramadan A., Soliman G., Sawsan S.
