摘要：
[Objective]Synthesize the luteolin-chrome complex,ascertain its molecular structure,and investigate its ability to scavenge DPPH free radical. [Methods]Absolute ethyl alcohol was taken as the reagent,and the luteolin-chrome complex was synthesized at pH 9. 76 and80 ℃; After the structure was ascertained via IR,UV,TG-GTA and elemental analysis,effects of the complex to scavenge DPPH free radical were investigated by HPLC method and spectrophotometry. [Results] The composition of luteolin-chrome complex was: C15H9O6Cr(COOCH3)2(H2O)2·2H2O; the scavenging effect of luteolin-chrome was stronger than that of luteolin. [Conclusions]The combination of luteolin and Cr3 +enhances the bioactivity of luteolin to resist DPPH.
