To study the inhibition of compound lightyellow sophora root collutory on oral bacteria. The standard strains of common oral bacteria were cultured and proliferated by corresponding media in vitro. The minimum inhibitory concentration (MIC), MIC(50), MIC(90) of compound lightyellow sophora root collutory were determined. The bacteriostatic effects were determined by the plating method. The MIC of compound lightyellow sophora root collutory were lower than the stock solution concentration. It was showed that compound lightyellow sophora root collutory had the same effect as tea polyphenol on oral bacteria. To Actinomyces naeslundii, compound lightyellow sophora root collutory inhibited the bacteria growth more obviously than tea polyphenol. The result showed that there was no remarkable difference between the compound lightyellow sophora root collutory and tea polyphenol by the plating method. Compound lightyellow sophora root collutory can inhibit the oral bacteria growth obviously.
