Abstract：

Flavones　such　as　morin,　rutin,　quercitrin,　quercetin　and　wogonin　were　found　to　be　able　to　strongly　enhance　the　electro-chemiluminescence　(ECL)　of　the　Ru(bpy)32+　system.　Based　on　this,　a　novel　ECL　method　with　good　stability　and　reproducibility　could　be　developed　for　determination　of　flavones.　Under　the　optimum　conditions,　the　enhanced　ECL　intensity　was　linear　with　the　flavones　concentration　in　a　wide　range.　The　detection　limits　(defined　as　S:N　=　3)　for　morin,　rutin,　quercitrin,　quercetin　and　wogonin　were　3.2　×　10-7　mol/L,　4.3　×　10-7,　1.8　×　10　-7,　8.0　×　10-8　and　1.0　×　10-7　mol/L,　respectively.　In　addition,　the　possible　mechanism　for　the　Ru(bpy)　32+　ECL　system　in　the　presence　of　flavones　is　also　discussed.　Copyright　©　2008　John　Wiley　&　Sons,　Ltd.
