Abstract
In the dental office, diabetes mellitus is a chronic affection that many patients suffer. Apart from the treatment of all diabetic patients, they use homeopathic medicines. We consider the importance of knowing these extracted hypoglycemic plants and their way of acting by the dentist.In this study we investigated some extracts obtained from vegetal sources used by hypoglycaemic action: Juglans regia L. -nut, Morus nigra L. -black mulberry, Olea europaea L. -olive. We followed the level of antioxidant compounds and the antioxidant capacity in the alcoholic extracts. Our results indicate higher antioxidant efficiency in the extracts from young plant parts, with meristematic tissues, and also a modified phytochemical profile, compared to the extract from mature plant parts.

The maximum antioxidant activity may be found in the extract of nut buds by DPPH, FRAP, SNP methods and inhibits the most powerful nitric oxide (NO) radicals, while with CUPRAC method, the extract from black mulberry shoots is indicated to have the strongest antioxidant effect
Summary
Total flavonoid dosing was performed spectrophotometrically in the visible domain, based on the aluminum ion coordination to the hydroxyl and ketone groups of the flavonoid structure, and the formed complex has a yellow color. Quantitative expression was performed in rutoside, building for this purpose a calibration curve in the rutoside, under similar conditions to the determination performed on the samples. To each 0.1 mL of the described extracts is added 5 mL of 10 % sodium acetate and 3 mL of 2.5 % aluminum chloride. Each solution is brought to 25 mL with methanol. As standards were used metallogenic solutions of rutoside, having concentrations between 4 and 20 μg/mL, processed to the samples. 1) was obtained with a solution of known concentration of rutoside The calibration curve (fig. 1) was obtained with a solution of known concentration of rutoside
