  1. 1. “+” represents bacteria can be observed in the experimental concentration; “” represents bacteria can not be observed in the experimental concentration
  2. 2. Four compound concentration levels (1 mg/ml、0.33 mg/ml、0.11 mg/ml、0.037 mg/ml) represent four antibacterial activity intensities (0、1、2、3), respectively
