Abstract

Abstract: Having synthesized the complex Cr(Ⅲ) - quercetin([Cr(C15H9O7)2Cl·H2O]·7H2O) and characterized it with the methods of IR spectra, UV- spectra, thermal analysis and elemental analysis etc., the free radical (·OH, ·O2, DPPH·) scavenging activities of the complex were investigated in this paper. The results showed that free radical scavenging activities of the complex on OH·, O2· and DPPH· were obviously stronger than that of the quercetin.

Key words: complex chromium(Ⅲ)-quercetin； ·OH radical； O2- radical； DPPH·, radical；
