Determination of Biological Active Components in Propolis Samples Produced by Using Different Methods

In this study, biologically active compounds were investigated in propolis samples produced in different periods by using different propolis production methods. Langstroth type wooden beehives were used in the study. Propolis samples were collected in the nectar period and in the pre-winter period for the two years. As propolis production traps, plastic grid inner cover, with wooden Bell Board types attached to the front and side face of the hive were used. The powdered propolis samples were exctracted by using 96% ethanol for one week to obtain the solution. The phenolic components of propolis extracts were determined by GC-MS. The most common compounds in propolis samples are benzoic acids, coumaric acids, hexadecanoic acid, cinnamic acids, eudesmol and bisabolol and their derivatives. Propolis produced in different periods and years were found to contain 17 components in common
