Широкий спектр фармакологических эффектов, структурное сходство веществ, входящих в их состав, с соединениями – метаболитами, присутствующими в организме человека, доказывают их огромный потенциал, делая их объектом научного исследования, и определяют применение некоторых представителей в традиционной и народной медицине. В контексте возрастающего интереса населения к фитомедицине и принципам здорового образа жизни очевидной является перспективность изучения биологической активности Шлемника обыкновенного (Scutellaria galericulata L.) как растительного объекта, который может быть использован в качестве исходного сырья для получения лекарственных средств. Целью исследования явилось определение суммарного содержания флавоноидов в пересчете на лютеолин-7-гликозид в различных морфологических частях Scutellaria galericulata L., культивированного на территории Астраханской области, с учетом вегетативной фазы. Материалы и методы исследования. Объектом исследования служили стебли, листья, цветки и корни Scutellaria galericulata L. Определение влажности было выполнено согласно требованиям Государственной фармакопеи XV издания. Результаты исследования. Данные, полученные при изучении влажности, подтвердили соответствие показателей требованиям Государственной фармакопеи, что позволило перейти к следующему этапу исследования, направленному на выявление локализации содержания флавоноидов в изучаемом объекте. Зафиксировано максимальное содержание веществ данной группы в пересчете на лютеолин-7-гликозид, в корнях, листьях и цветках Scutellaria galericulata L. Показано, что в стеблях содержится минимальное количество производных флавана. Показано, что наивысшие концентрации флавоноидов в корнях достигались в конце вегетационного периода. Содержание флаваноидов в листьях зависело от его стадии: начала вегетации, периода бутонизации и цветения. Существенных колебаний уровня фенольных соединений в цветках не установлено, вероятно, по причине ограниченности периодов сбора образцов, в результате которой корни содержали больше флавоноидов по сравнению с листьями, значительно превосходя по их содержанию стебли и цветы. Заключение. Данные экспериментального исследования указывают на необходимость соотношения периода вегетации и места локализации биологически активных веществ с их количественным содержанием в растении. Установленная взаимосвязь позволит впоследствии определить оптимальные условия хранения лекарственного растительного сырья, а также особенности получения лекарственных средств на его основе, гарантируя их качество и безопасность.</p></abstract><trans-abstract xml:lang="en"><p>The plants of the genus Scutellaria of the Lamiaceae family, which includes more than 420 species, are a promising object for study due to their unique chemical composition. The wide range of pharmacological effects, the structural similarity of the substances included in their composition with compounds – metabolites present in the human body, prove their enormous potential, making them an object of scientific research, and determines the use of some representatives in traditional and folk medicine. In the context of the growing interest of the population in phytomedicine and the principles of a healthy lifestyle, the prospects of studying the biological activity of Scutellaria galericulata L. as a plant object that can be used as a raw material for the production of medicines are obvious. The aim of the study was to determine the total content of flavonoids in terms of luteolin-7-glycoside in various morphological parts of Scutellaria galericulata L. cultivated in the Astrakhan region, taking into account the vegetative phase. Research materials and methods. The objects of the study were stems, leaves, flowers and roots of Scutellaria galericulata L. The moisture content was determined according to the requirements of the State Pharmacopoeia XV edition. Study results. The data obtained during the humidity study confirmed the compliance of the indicators with the requirements of the State Pharmacopoeia, which allowed us to proceed to the next stage of the study aimed at identifying the localization of flavonoid content in the studied object. The maximum content of substances of this group, in terms of luteolin-7-glycoside, was recorded in the roots, leaves and flowers of Scutellaria galericulata L. It was shown that the stems contain  a minimum amount of flavan derivatives. It was shown that the highest concentrations of flavonoids in the roots were achieved at the end of the growing season. The content of flavonoids in the leaves depended on its stage: the beginning of vegetation, budding and flowering. Significant fluctuations in the level of phenolic compounds in the flowers were not established, probably due to the limited periods of sample collection, as a result of which the roots contained more flavonoids compared to the leaves, significantly exceeding the stems and flowers in their content. Conclusion. The data of the experimental study indicate the need to correlate the vegetation period and the location of biologically active substances with their quantitative content in the plant. The established relationship will subsequently allow us to determine the optimal storage conditions for medicinal plant raw materials, as well as the features of obtaining medicines based on it, guaranteeing their quality and safety.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Scutellaria galericulata L.</kwd><kwd>биологически активные вещества</kwd><kwd>флавоноиды</kwd><kwd>лютеолин-7- гликозид</kwd><kwd>фаза вегетации</kwd><kwd>морфологическая группа</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Scutellaria galericulata L.</kwd><kwd>biologically active substances</kwd><kwd>flavonoids</kwd><kwd>luteolin-7-glycoside</kwd><kwd>vegetation phase</kwd><kwd>morphological group</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">Irvin L., Jackson C., Hill A.
