        Antimicrobial Effects of Chlorogenic Acid and Related Compounds

        Faisal Kabir,Shigeru Katayama,Noriko Tanji,Soichiro Nakamura 한국응용생명화학회 2014 Applied Biological Chemistry (Appl Biol Chem) Vol.57 No.3

        Chlorogenic acid (CGA) is a natural chemical estercomposed of caffeic acid and (-)-quinic acid, and is furthermetabolized into active compounds in the living body. Here, weaimed to provide fundamental information on the antimicrobialaction of CGA and related compounds against the Gram-negativebacterium Escherichia coli IFO 3301. Bacteriostatic effects wereassessed by spectrophotometry, and bactericidal effects weredetermined by enumerating viable cells on MacConkey agar plates. CGA and related compounds exhibited specific antimicrobialactivity and corresponding reduction in log survival ratio, inwhich ferulic, isoferulic, benzoic, and hydroxybenzoic acidsexhibited obvious antimicrobial activity against E. coli. In a timekillassay, it was observed that bactericidal effects were associatedwith treatment time, temperature, and dose. A reduction in logsurvival ratio was observed at low pH as well as under thermalstress condition. Thus, we demonstrated that CGA and relatedcompounds have not only bacteriostatic effects but alsobactericidal effects.
