Abstract:
Since it was proved that diabetes mellitus complications, especially nephropathy, retinopathy, arteriopathy or neuropathy, are
closely related to increased oxidative stress, researches were directed to find natural antioxidants which can be safely
administered to patients on long-term safety. Hence, many medicinal plants have been recommended for the management of
diabetes due to their significant metabolic and antioxidant effects. The aim of our research was to evaluate the influence of an
ethanolic extract of Syringae vulgaris flos f. alba on the metabolic and antioxidant status of streptozotocin-induced diabetic
rats in comparison with an ethanolic extract of Phaseoli sine seminibus fructus, recognized worldwide for its antidiabetic and
antioxidant virtues. The effects of oral administration of plant extracts as a once daily dose for six-weeks to diabetic rats were
investigated on blood glucose and cholesterol concentration, the degree of lipid peroxidation and the activity of several
antioxidant enzymes (glutathione peroxidase, glutathione reductase, superoxide dismutase).
