Comparative study of chemical modification of quercetin and antibacterial activity

Yanhu Guo

Abstract

Based on the chemical modification of quercetin(Qu),the complexes of quercetin of first transition series chemical element of life were synthesized.Antibacterial activity of quercetin rutin complexes has been focused on in the comparative study.The results showed that antibacterial activity of quercetin complexes to the four strains from high to low was Staphylococcus aureus Escherichia coli Bacillus sukatilis beer yeast.Antibacterial activity of quercetin complexes from strong to weak was Qu-CuQu-ZnQu-CoQu-NiQu-MnQu-CrQu-FeQu.And abacteriostatic activity stability of the quercetin complexes was better than rutin.
