Abstract
[Objective] The aim was to investigate the antibacterial effects of 32 kinds of Chinese herbal medicines including FRUCTUS FORSYTHIAE ,RHIZOMA COPTIDIS, RADIX ET RHIZOMA SEU CAULIS ACANTHOPANACTS SENTICOSI and so on. [ Method ]95％ ethanol was adopted to extract the active ingredients from the herbal medicine, whose antibacterial activity was then determined by oxford cup method with Escherichia coli and Staphylococ cus aureus as the indicator bacteriaH. [ Result] Among the 32 kinds of herbs,the extracts from 26 medicines including RHIZOMA ET RADIX POLYGONI CUSPIDATI had inhibition effect on the Staphylococcus aureus ;while 23 medicines including FRUCTUS FORSYTHIAE had inhibition effect on E. coli,and the antibacterial effect intensified with the increase of the medicine concentration within certain range. The minimum inhibitory concentrations of FRUCTUS FORSYTHIAE and RHIZOMA COPTIDIS on E. coli were 4 and 10 mg/ml respectively ,while that on S. aureus were 6 and 8 mg/ml. [ Conclusion]The research laid the foundation for further studying the antibacterial mechanism of the herbal medrcine and developing high efficient antibiotics with low toxicity.关键词
