Abstract: The chemical constituents of Brazilian propolis were determined and its quality and safety were also evaluated. Results indicated that the total polyphenol and flavonoids content in Brazilian propolis was 7.3 %, which is much higher than that mentioned in the national standard. The content of 75% ethanolic extract was 46.07%.The content of protein was 106g/kg. The content of fat was 152g/kg. Fat-soluble vitamins Vitamin A and Vitamin E were 161mg/kg, 1382mg/kg respectively. Meanwhile, 17 kinds of amino acid were identified in Brazilian propolis. 10 fatty acids and 17 microelements were found in Brazilian propolis. However, the pesticide residue was very low. DDT, methamidophos, parathion, benzene hexachloride (BHC) were not detected. And heavy metal mercury (Hg) was not detected, the content of Arsenic (As) was 0.01 mg/kg. These data suggest that Brazilian propolis is nutritional, safe and of high quality. The research gives a solid base to the development of functional foods with Brazilian propolis.
