Influence of Collection Methods on Propolis Quality

Abstract. Propolis samples were analyzed in order to determine the effect of collection method over the general quality of this bee product. In this respect, during 2010-2011 were collected 12 propolis samples using a propolis collector and 12 samples using the hive tool. Propolis samples were prepared as Ethanolic extracts (1%, w/v) and analyzed for phenolics composition (total phenolics, flavones/flavonols, flavanones/dihydroflavonols). Wax content was also determined by Soxhlet extraction. The results obtained proved that collection method has great influence over both wax content and quantity of phenolic compounds from propolis. In conclusion propolis gathered by means of a collector has lower amount of wax and higher amount of phenolics than propolis gathered by hive tools.
