Determination of the Antioxidant Capacity of Tragopogon Pratensis Species and Testing Their Pancreatic and Hepatic Regenerative Activity

This experimental study was aimed at assessing the total polyphenol and flavonoid content of Tragopogon pratensis (folium) vegetal extract and evaluating the histopathological status of mice with liver problems and diabetes during therapy with 20% hydroalcoholic extract of T. pratensis (folium) . The diabetes in mice was induced by single intraperitoneal (i.p.) dose of 180 mg/kg b.w. streptozotocin. The experiment involved two congtrol groups: the first (I) group consisted of mice with normal pancreatic function; the second (II) group consisted of mice with experimentally induced diabetes. The third (III) group of mice with experimentally induced diabetes was treated with T. pratensis extract at a dose of 150 mg/kg b.w.. The first and second groups were not treated, while the third group received daily the established medication once a day, in the morning at the same time (9 a.m), for five weeks. The obtained results showed that the administration of T. pratensis tincture triggers the hepatic regenerative processes, restores functional activity of the liver, and positively influences functionality of the pancreas. The molecular docking analysis supports results of the experimental study.
