Abstract:Bacteriostatic effects of extracts of five common antibacterial Chinese herbs were studied here. Results showed that Taraxacum extracts by 50 ℃ water extraction had the same MIC values with 50% ethanol extraction of Taraxacum, which were 0.25 g/mL, 0.125 g/mL, 0.5 g/mL, respectively. And the potassium sorbate possessed the strongest antifungal activities with 0.1 g/mL, 0.1 g/mL and 0.8 g/mL.
