Propolis samples, used as biological material in the present study, were collected from different areas in Transylvania and investigated in order to establish their antioxidant capacity. The antioxidant properties were evaluated using 2,2-diphenyl-1-picrylhidrazyl (DPPH) radical scavenging capacity assay. IC50 values were also determined for the studied propolis samples. The lower the IC50 value is, the greater the overall effectiveness of the antioxidant in question. IC50 values for the investigated propolis samples ranged between 1.67mg/ml and 3.28mg/ml. The lowest IC50 value, 1.67mg/ml corresponding to sample PS 10 indicates a great antioxidant activity of the mentioned sample. |

This paper contents a summary about antimicrobial compounds from royal jelly. Royal Jelly is a nutritive secretion produced by the hypopharyngeal and mandibular glands of worker bees; it is the main nutritional font of the queen honeybee and contains vitamins, carbohydrates, minerals and proteins. It possesses a number of pharmacological activities and is widely used in commercial medical products, health foods, and cosmetics in many countries. Peptides isolated from natural fonts are the object of several studies aimed at finding new molecules possessing antibacterial activity. |
