Research ArticleOpen accessIn the abstractAntioxidant, Free Radical Scavenging and Metal Chelating Characteristics of PropolisHikmet Geckil, Burhan Ates, Gokhan Durmaz et al.This study was undertaken to determine the reducing characteristics, metal chelating capability, anti-lipid peroxidative and antiradical properties of propolis compared to two widely used artificial antioxidants, Butylated Hydroxyanisole (BHA) and Butylated Hydroxytoluene (BHT). The water and ethanol extracts of propolis showed significantly a different degree of metal chelating, radical scavenging activity and reducing power. In general, ethanol extracts of propolis … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 1 · 31 Mar 2005 · 9,088 accessesView PDFCite
