Abstract

Objective:the antimicrobial effects of the petroleum ether extract from leaves and stem of M.dahuricum DC.against 3 kinds of bacterial and 12 kinds of plant pathogenic bacteria were studied.Methods:growth rate method and Kirby-Bauer method.Results:the petroleum ether extract had the varying degree inhibitory action to 12 kinds of plant pathogenic bacteria,but was not obvious to the bacterium inhibitory action.Conclusion:The Menispermum dahuricum stem leaf petroleum ether extraction overall suppresses the plant pathogens effect was good,but bad to the bacterium inhibitory action.
