Using plants in treating some diseases has become a tradition, ‘the nature’s pharmacy’ being an important source of therapy. At present, the medicinal plants properties are being re-assessed due to progress made in chemical, pharmaceutical and clinical research of plants and due to forms obtained from vegetal products, but especially due to the advantages they offer. In the context of more frequent use of natural products with pharmaceutical and therapeutical aims, both at a national and at an international level, our research hints at highlighting and giving details about a series of effects produced by vegetal extracts of Aronia melanocarpa and Silybum marianum on certain physiological, biochemical and histopathological processes at CD1 mice. In this study, 2 hydro-alcoholic extracts obtained from 2 species of medicinal plants (Aronia melanocarpa and Silybum marianum), were tested in order to analyse the hypoglycemiant activity. The data accumulated in the specialty literature reveal that the phytotherapeutic use of extracts of Aronia melanocarpa and Silybum marianum is based only on the major pharmacologic effect while the intimate action mechanism of the two vegetal products, al cellular and subcellular level, is not known. Starting from these premises, we considered useful the initiation of a comparative study regarding the antidiabetic influence of fluid extracts of Aronia melanocarpa and Silybum marianum upon mice experimentally intoxicated with alloxan monohydrate solution. CDI mice were used as an experimental model in order to induce diabetes: alloxan monohydrate was injected intraperitoneal with concentration of 130 mg/kg body (Ahmed Saber Abu – zaiton, 2013), dissolved in physiological serum, during two weeks, at an interval of 3 days. Both extracts acted positively by lowering blood sugar and by returning to normal body weight in diabetic mice. Aronia extract has a pronounced effect compared to milk thistle extract for both parameters monitored in the experiments.
