Effective components of Huanglian berberine is the main difference, in order to further study the effects of different concentrations of antibacterial properties of antibacterial activity of berberine hydrochloride, the experiment on it and the minimum inhibitory concentration was studied. In this experiment, the extraction of berberine hydrochloride and refined dilute sulfuric acid method, Bacteriostatic Experiment in vitro bacteriostatic effect of berberine hydrochloride solution with different concentrations of berberine hydrochloride and the minimum inhibition concentration (MIC) by plate method. Berberine extraction rate was 3.8%, the purity was 73.3%. There was significant difference between the antibacterial activity of berberine hydrochloric acid at different concentrations, the minimum inhibitory concentration (MIC) of Escherichia coli 0.4mg/ml, berberine hydrochloride in vitro had stronger bacteriostasis.
