Introduction. It is urgent to search for plants that can become sources of biologically active substances for the creation of new highly effective and safe medicines. One of these plants is the crowned sickle (Serratula coronata L.). The value of crowned serpuha is determined by its high content of phytoecdysteroids and flavonoids. The purpose of the work is to study the acute toxicity, anti-inflammatory activity and capillary-strengthening effect of the flavonoid fraction of the herb Serpucha crown. Material and methods. In the Department of Experimental Pharmacology of the Federal State Budgetary Institution VILAR, a study of the pharmaco-logical activity of the flavonoid fraction of the herb Serpucha crowned was carried out. Acute toxicity parameters were assessed using the Kerber method. The toxicity class of the test substance was determined according to GOST 12.1.007-76 "Harmful substances. Classification and general safe-ty requirements." The anti-inflammatory effect of the flavonoid fraction of the herb Serpucha crown was studied in models of formaldehyde edema and interstitial edema. The effectiveness of the anti-inflammatory effect of the flavonoid fraction of the herb crowned serpentine in vitro experiments was assessed by the rate of the enzymatic reaction catalyzed by inducible NO synthase. The activity of the iNOS enzyme in experiments was assessed by the rate of the reaction catalyzed by iNOS in vitro at 37 C. The study of the capillary-strengthening effect of the flavonoid fraction of the herb Serpucha crowned was carried out according to the "Method for determining the reactivity of skin capillaries to inflammatory stimuli" on a model of local in-flammatory reaction (xylene inflammation) in rats. Results. When studying the acute toxicity of the flavonoid fraction of the herb Serpucha crown, LD50 values were not established, since doses of the studied extract administered into the stomach of mice did not cause death of the animals. In accordance with the classification of toxicity of chemical substances according to GOST 12.1.007-76 "Harmful substances. Classification and general safety requirements", the flavonoid fraction of the herb crowned Serpucha is a low-hazard substance. As a result of the analysis of the data obtained, it was established that the flavonoid fraction of the herb serpukha crowned in doses of 100 and 200 mg/kg has an anti-inflammatory effect, significantly reducing formaldehyde edema in animals by 18 and 20%, respectively, compared with the control group of animals. It was established that the flavonoid fraction of the herb Serpucha crowned at a dose of 200 mg/kg has a pronounced anti-exudative effect, significantly reducing interstitial edema in animals by 22% compared to the control group of an-imals. In vitro experiments, the flavonoid fraction of the herb Serpucha crown inhibits the rate of the iNOS reaction by 1.5 times compared to the con-trol, which indicates the presence of pronounced anti-inflammatory activity of this sample. The studied fraction has a pronounced capillary-strengthening effect under the conditions of an experimental model of xylene inflammation, reducing the permeability of the vascular wall. Conclusions. The results of the studies indicate that the flavonoid fraction of the herb Serpucha crown, in terms of acute toxicity, belongs to the cat-egory of low-hazard substances and has a pronounced anti-inflammatory and capillary-strengthening effect.

Aim. To evaluate the antitoxic activity of chicory herb extract fractions in rats with toxic hepatitis.Materials and methods. There were 64 male rats were divided into groups of 6 animals that received the whole chicory herb extract, its fractions, or the reference drug (RD) and 2 groups did not receive any drug. The Silimar substance (a dry purified extract obtained from the fruits of milk thistle [Silybum marianum]) was chosen as RD. Animals from one of the groups that did not receive the drug (control group) and the groups that received drugs were injected with CCl4 to simulate toxic liver damage. The last group of animals received neither drugs nor CCl4 (intact animals). The changes in the activity of biotransformation enzymes (cytochrome P450 [cytР450] and glutathione transferase [GT]) in hepatocytes and serum liver enzymes (AST, ALT and AP) were assessed.Results. There was a decrease in cytР450 and GT activity in the liver microsomes of control rats (having CCl4 hepatitis without treatment) compared with intact animals. These parameters were more in the animals that were administrated with chicory herb extract, its fractions, and RD than in control animals. The administration of the whole extract, aqueous fraction, and RD led to an increase in the activity of cytP450 and GT enzymes almost to the level of the same indicators in intact animals. Pronounced grown in the activity of serum liver enzymes (ALT, AST and AP) were found after CCl4 injection. Administration of common chicory herb fractions before toxic liver damage caused a decrease in the grown of the activity of these enzymes. The greatest inhibitory effect on the grown of the activity of these liver enzymes had RD, aqueous and butanolic fractions of chicory herb. Despite a significant decrease in hyperfermentemia found in groups of animals treated with fractions of chicory herb, AST, ALT and AP activities did not reach the level that was in the intact animal group.Conclusion. The aqueous and butanolic fractions of the chicory herb extract had the highest antitoxic activity in experimental animal toxic liver injury.

Экспериментальный гепатит у крыс вызывали однократным введением подкожно 50% масляного раствора тетрахлорметана в объеме 0,4 мл на 100 г, через 1 ч после последнего введения исследуемых веществ. Через 48 ч после введения тетрахлорметана брали кровь из хвостовой вены крыс, получали сыворотку и проводили её биохимический анализ. Затем крыс подвергали эвтаназии в СО2 камере, извлекали печень для проведения патогистологического исследования. результаты. Введение экстракта травы топинамбура в дозе 500 мг/кг и препарата сравнения Силимар в дозе 100 мг/кг снижало токсическое действие тетрахлорметана на печень лабораторных животных, что подтверждено результатами биохимического исследования сыворотки крови подопытных животных и при гистологическом исследовании их печени. Внутрижелудочное введение крысам экстракта топинамбура в дозе 100 мг/кг приводило к незначительному снижению активности ферментов-маркеров функционального состояния и не влияло на морфологическую структуру печени опытных животных. Заключение. Сухой экстракт травы топинамбура в дозе 500 мг/кг обладает гепатопротекторным действием и является перспективным объектом для дальнейшего углубленного фармакологического изучения. Introduction. Some bioactive substances (e.g., flavonoids, phenolic acids, sesquiterpenes, polysaccharides, and amino acids) in Helianthus tuberosus L. leaves have antibacterial, anti-inflammatory, and antioxidant activity. These active ingredients may provide effective alternatives to imported hepatoprotective medicines. Aim of the study was to assess the hepatoprotective activity of extracts of the Helianthus tuberosus L. dried herb in male rats with carbon tetrachloride intoxication.methods. The composition of Helianthus tuberosus L. herb dry extract includes hydroxycinnamic acids and flavonoids. The predominant phenolic compound is chlorogenic acid. The hepatoprotective activity of the H. tuberosus extract doses of 100 and 500 mg/kg body weight was compared in carbon tetrachloride-treated rats. The rats were divided into five groups with ten animals in each. The first group consisted of intact animals; the second group received carbon tetrachloride, the third and the fourth groups received the H. tuberosus extract at a dose of 100 or 500 mg/kg plus carbon tetrachloride (TCM). The fifth group received Silymar® as a comparator drug. 48 hours after the TCM administration, serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP) activities and total bilirubin concentration were measured. Pathomorphology of rat liver was studied by histological methods using section staining with hematoxylin and eosin.results. Prior H. tuberosus extract administration reduced the toxic TCM effect on liver cells in experimental toxic hepatitis. In animals treated with H. tuberosus at a dose of 500 mg/kg body weight, the ALT activity was decreased by 31 %, the AST activity by 20%, the alkaline phosphatase activity by 19%, and the total bilirubin concentration by 16% as compared with the respective variables in the Silymar® group of animals that were not treated with the extract. The histological study showed that the H. tuberosus extract administration to animals at a dose of 500 mg/kg reduced dystrophic changes in hepatocytes.conclusion. The H. tuberosus extract at a dose of 500 mg/kg has a pronounced hepatoprotective effect and it is promising for further pharmacological study for developing hepatoprotective drugs.
Introduction. Chicory (Cichorium intybus L.) is widely applied for liver disease treatment by traditional medicine of different countries; as well, it is the object for pharmacological research of hepatoprotective activity. In this regard, the method for obtaining dry extract of wild chicory herb (WCHE) is developed in the All-Russian Research Institute of Medicinal and Aromatic Plants.Aim. Aim of the research is determination of the qualitative composition of phenolic compounds, identification of the substances prevailing in WCHE and conducting pharmacological screening of the extract.Materials and methods. WCHE chemical composition has been explored with HPLC-MS/MS method; the main components were determined quantitatively with HPLC-UF method using single compounds that were isolated by us earlier and identified by NMR spectroscopy. WCHE pharmacological screening of hepatoprotective activity research was involving 50 male rats. Acute toxic hepatitis in animals was induced by a single subcutaneous injection of 50 % oily solution of tetrachloromethane (TCM) at a dosage of 0.4 ml per 100 g body weight. One hour before administration TCM, animals received WCHE at the doses of 100 or 500 mg/kg. 48 hours after TCM administration, the activity of serum enzymes alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), as well as the content of total bilirubin were determined for preliminary establishment of pharmacological activity. Pathomorphological studies of rat liver were carried out using histological methods. The liver histological structure was inspected using liver sections stained with hematoxylin and eosin.Results and discussion. The component composition of WCHE is represented by oxycoumarins, hydroxycinnamic acids and flavonoids. The dominant phenolic compounds are esculetin, chicoriin, chicoric, chlorogenic and caftaric acids. It was found under acute experimental toxic hepatitis, that preliminary WCHE administration reduces the toxic TCM effect on liver cells. In animals treated with WCHE at doses both 100 mg/kg and 500 mg/kg body weight, it was observed decreases in ALT activity by 35 % and 45 %, AST by 15 % and 28 %, alkaline phosphatase by 15 % and 21 %; the content of total bilirubin by 20 % and 29 %, respectively, in comparison with similar indicators in the group of animals that were not treated with the extract. The histological study showed that WCHE administration to animals at the doses of 100 and 500 mg/kg reduces dystrophic changes in hepatocytes, this effect is more pronounced at the extract dosage of 500 mg/kg.Conclusion. Main WCHE components are oxycoumarins (esculetin, chicoriin), hydroxycinnamic acids (chicoric, chlorogenic and caftaric). According to the results of screening studies, it was established that WCHE in doses of 100 mg/kg and 500 mg/kg is a promising object for further pharmacological research.
