“…Propolis from temperate zones generally consists of 50-60% resins and balsams, 30-40% of wax, 5-10% of essential and aromatic oils, 5% of pollen, and 5% of other substances (Mendoza et al, 1991). These substances comprise more than 210 different compounds identifi ed so far, such as aliphatic acids, aromatic esters and acids, fl avonoids, fatty acids, carbohydrates, aldehydes, amino acids, ketones, chalcones, dihydrochalcones, terpenoids, vitamins (B1, B2, B6, C, and E), and minerals (aluminum, antimonium, calcium, cesium, copper, iron, lithium, manganese, mercury, nickel, silver, vanadium, and zinc) (Ghisalbert, 1979;Moreira, 1990;Marcucci, 1995;Sousa et al, 2007;Chang et al, 2008;Lustosa et al, 2008). Therefore variation in propolis components could affect its properties (Nakamura et al, 2010).…”
