Study on the Antimicrobial Activity of Flavonoids in Clausena indica(Datz). Oliv. Fruits

摘要(Abstract):

[Objective] To extract flavonoids from Clausena indica(Datz) .Oliv.fruits and study their antimicrobial activities.[Method] Microwave-assisted method was used to extract flavonoids,whose antimicrobial activities were determined by filter paper diffusion method and LB medium double dilution method.[Result] The concentration of concentrated flavonoids extracted from Clausena indica(Datz) .Oliv.fruits was 162.298 5 mg/ml,and flavonoids presented good antimicrobial activities against Staphylococcu saureus,Bacillus subtilis and Escherichia coli with the MIC of 20.29,40.58 and 81.15 mg/ml,but the antimicrobial activity against Mucor and Saccharomyces cerevisiae was not obvious.[Conclusion] The study could provide theoretical basis for further exploring and developing Clausena indica(Datz) .Oliv.resources and producing new,safe and high-efficient biopreservatives.
