Abstract:

Royal jelly (RJ) is one of the most attractive bee products. RJ has long been used in traditional medicine. Due to various pharmacological properties, including antioxidative, anti-inflammatory and antibacterial properties, RJ has been widely consumed in daily diets in numerous countries. The purpose of the present study is to find out some correlations of physicochemical parameters, antioxidant activity and total polyphenol content of fresh RJ samples. The following parameters were analyzed in fresh RJ samples: water content, proteins, pH, total acidity, electrical conductivity, sugars (glucose, fructose, sucrose), trans-10-hydroxy-2-decenoic acid (10-HDA). The antioxidant activity of RJ was examined by two methods: 1,1-diphenyl-2-picrylhydrazyl (DPPH) and the ferric reducing antioxidant power (FRAP) assay. Total phenolic content was determined according to Folin Ciocalteu procedure. High positive linear correlations between the total antioxidant activity determined by the DPPH method and 10-HDA (r=0.858, p<0.05) and FRAP method and total polyphenols (r=0.812, p<0.05) were found.
