title: [Investigation on antibacterial activity of Forsythia suspense Vahl in vitro with Mueller-Hinton agar].
abstract: OBJECTIVE
  To evaluate the antibacterial activity of Forsythia suspensa in vitro with different media.
  
  
  METHODS
  MIC determination of Forsythia suspensa against Staphylococci was performed by the agar dilution method.
  
  
  RESULTS
  MIC90 of decoction of Forsythia suspensa against Staphylococcus epidermidis in M-H agar was 1:640, but in nutrient agar 1:40, the antibacterial activity with M-H agar being 16 fold higher than nutrient agar.
  
  
  CONCLUSIONS
  The M-H agar should be recommended to replace nutrient agar as medium in the antibacterial experiment of Traditional Chinese medicine, and it is better to use multipoint inoculating device in the sensitivity test.
