Род Lagotis (Plantaginaceae) включает виды, традиционно применяемые для лечения заболеваний печени. Несмотря на свой потенциал, лаготис Королькова (Lagotis korolkowii (Regel &amp; Schmalh.) Maxim.) остается недостаточно изученным в фитохимическом и фармакологическом отношении, особенно в части его безопасности и гепатопротекторных свойств.</p></sec><sec><title>Цель</title><p>Цель. Оценка острой пероральной токсичности и гепатопротекторной эффективности экстракта Lagotis korolkowii (Regel &amp; Schmalh.) Maxim. на экспериментальных моделях.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Острую токсичность оценивали на мышах-альбиносах в соответствии с ГОСТ 32644-2014 и руководством А. В. Стефанова, применяя разовые пероральные дозы до 10 000 мг/кг. Гепатопротекторную активность исследовали на крысах-самцах с моделью острого парацетамолиндуцированного гепатита (1000 мг/кг в течение 2 дней). Группы лечения получали экстракт растения перорально в дозах 50, 100 и 200 мг/кг в течение 7 дней после интоксикации. Проводили оценку общего состояния, показателей гематологического (общий анализ крови) и биохимического (АЛТ, АСТ, билирубин, общий белок и др.) анализов крови.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Средняя летальная доза (ЛД50) экстракта Lagotis korolkowii (Regel &amp; Schmalh.) Maxim. превысила 10 000 мг/кг, что позволяет классифицировать его как практически нетоксичное вещество (V класс). В модели гепатотоксичности экстракт дозозависимо уменьшал вызванные парацетамолом нарушения. Доза 50 мг/кг продемонстрировала наибольшую активность, достоверно снижая уровни АЛТ (на 4 %), АСТ (на 27 %) и прямого билирубина (на 39 %) в плазме, а также повышая уровень общего белка (на 17 %) по сравнению с группой интоксикации. Также наблюдалась положительная динамика в нормализации количества эритроцитов, уровня гемоглобина и лейкоцитов.</p></sec><sec><title>Заключение</title><p>Заключение. Экстракт Lagotis korolkowii (Regel &amp; Schmalh.) Maxim. обладает высоким профилем безопасности и проявляет значительные дозозависимые гепатопротекторные эффекты против повреждения печени, индуцированного парацетамолом, при этом доза 50 мг/кг показала оптимальную эффективность. Полученные данные подтверждают его потенциал в качестве источника для разработки безопасных и эффективных гепатопротекторных фитопрепаратов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. The genus Lagotis (Plantaginaceae) comprises species traditionally used for treating liver disorders. Lagotis korolkowii (Regel &amp; Schmalh.) Maxim., despite its potential, remains phytochemically and pharmacologically underexplored, particularly regarding its safety and hepatoprotective properties.</p></sec><sec><title>Aim</title><p>Aim. This study aimed to evaluate the acute oral toxicity and hepatoprotective efficacy of an extract from Lagotis korolkowii (Regel &amp; Schmalh.) Maxim. in experimental models.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Acute toxicity was assessed in albino mice following GOST 32644-2014 and Stefanov's guidelines, administering single oral doses up to 10,000 mg/kg. Hepatoprotective activity was investigated in male albino rats with paracetamol-induced acute hepatitis (1000 mg/kg for 2 days). Treatment groups received the plant extract orally at doses of 50, 100, and 200 mg/kg for 7 consecutive days post-intoxication. Evaluations included observation of general condition, mortality, hematological analysis (complete blood count), and blood biochemical parameters (ALT, AST, bilirubin, total protein, etc.).</p></sec><sec><title>Results and discussion</title><p>Results and discussion. The median lethal dose (LD50) of Lagotis korolkowii (Regel &amp; Schmalh.) Maxim. extract exceeded 10,000 mg/kg, classifying it as practically non-toxic (Class V). In the hepatotoxicity model, the extract dose-dependently ameliorated paracetamol-induced alterations. The 50 mg/kg dose demonstrated the highest activity, significantly reducing plasma ALT (by 4 %), AST (by 27 %), and direct bilirubin (by 39 %) levels while increasing total protein (by 17 %) compared to the intoxicated control group. Positive normalization of erythrocyte, hemoglobin, and leukocyte counts was also observed.</p></sec><sec><title>Conclusion</title><p>Conclusion. Lagotis korolkowii (Regel &amp; Schmalh.) Maxim. extract possesses a high safety profile and exhibits significant, dose-dependent hepatoprotective effects against paracetamol-induced liver damage, with the 50 mg/kg dose showing optimal efficacy. These findings support its potential as a source for developing safe and effective hepatoprotective phytomedicines.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>средняя летальная доза (ЛД50)</kwd><kwd>эритроцит</kwd><kwd>гемоглобин</kwd><kwd>лейкоцит</kwd><kwd>парацетамолиндуцированный гепатит</kwd><kwd>биохимические маркеры</kwd></kwd-group><kwd-group xml:lang="en"><kwd>median lethal dose (LD50)</kwd><kwd>erythrocyte</kwd><kwd>hemoglobin</kwd><kwd>leukocyte</kwd><kwd>paracetamol-induced hepatitis</kwd><kwd>biochemical markers</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">Li W., Tojibaev K.
