This study was to investigate the antibacterial effect of Schizandrae fructus and Evodiae fructus extracts on S. mutans growth. The antibacterial effect of these extracts on S. mutans was good at Schizandrae fructus extract than the Evodiae fructus extract. The antibacterial activities of these extracts were measured 8.5 mm and 6.5 mm at 20 mg/ml concentration, respectively. The growth of S. mutans in control medium was the highest at 8 hrs, while the media of Schizandrae fructus and Evodiae fructus extracts added-medium(2 mg/ml) showed maximum growth at 16hrs. The pH values of the control medium was 5.08 at 8 hrs, but the media supplemented with Schizandrae fructus and Evodiae fructus extracts were 6.00, and 5.36 at 8 hrs, respectively. The amounts of total carbohydrate for the control media was 0.81 mg/ml at 8 hrs, but the media supplemented with Schizandrae and Evodiae fructus extracts were 1.32 mg/ml and 1.88 mg/ml at 8 hrs, respectively. In the change of culture medium proteins, the control culture broth and cultures supplemented with Schizandrae fructus and Evodiae fructus extracts were 8.39 mg/ml, 8.59 mg/ml and 9.97 mg/ml at 8 hrs, respectively. The S. mutans polysaccharide contents of the control medium and the media supplemented with Schizandrae and Evodiae fructus extracts were 300 mg/100 ml, 240 mg/100 ml and 280 mg/100 ml at 8 hrs, respectively.
