Pharmacological Activities of Flavonoids(IV) - Inhibitory Actions of Leukocyte Migration, Superoxide Anion Production and Lipid Peroxidation -

Effects of eight flavonoids and their related compounds on leukocytes migration, superoxide anion production and lipid peroxidation in the phagocytosis of latex beads or E. coli by guinea pig peritoneal exudate cells were studied in vitro. It shows that most of flavonoids generally inhibited the leukocytes migration and production of superoxide anion and malonedialdehydes. Their inhibitory activities in the phagocytosis of latex beads had more active than that of E. coli. Quercetin has the most inhibitory activity in leukocytes migration and production of superoxide anion and lipid peroxides at the concentration of 1, 2 and 10 $\mu{M}$. Catechin and rutin at the concentration of 2 and 10 $\mu{M}$ inhibited significantly the production of superoxide anion and lipid peroxides. Flavone, catechin, naringin and rutin at the concentration of 2 and 10 $\mu{M}$ inhibited significantly the leukocytes migration.
