Antimicrobial activities of extracts of Forsythia suspensa fruits and Dendranthema indicum buds and flowers against bacteria; Escherichia coli, Staphyloccus aureus, and Bacillus subtilis, and fungi; Aspergillus flavusn, Rhizopus stolonifer, Penicillium citrinum, Aspergillus niger, and Saccharomyces carlsbergensis, were investigated. The plants were extracted with 70% ethanol and the extracts were used for antimicrobial activity assay. All extracts exhibited significant inhibition activity against microorganisms at concentrations ranged from 1.66 to 100 /ml. The inhibition activity by the extract of D. indicum buds was stronger than by the extract of F. suspensa fruits and D. indicum flowers. D. indicum buds showed antimicrobial activity against S. aureus which was comparable to other medicinal plants. F. suspensa fruits and D. indicum flowers was suggested to be valuable sources as antimicrobial ingredients in food industry.
