Antimicrobial and radical modulation activity of AV-07, a poly-herbal formula.

Abstract

An extract of AV-07 was investigated for various biological activities. Pretreatment of mice with the AV-07 extract significantly protected them from lethal infection with E. coli. ESR spectroscopy showed that the extract produced radicals under alkaline conditions and enhanced the radical intensity of sodium ascorbate, suggesting its pro-oxidant action at higher concentrations. The extract effectively scavenged superoxide anion, produced by hypoxanthine-xanthine oxidase reaction and hydroxyl radical, produced by Fenton reaction. These data demonstrate that AV-07 extract contains various bioactive substances, suggesting its medicinal efficacy.
