Abstract：To investigate the inhibition effect of Pu’er tea extract,the Staphylococcus aureus(S.aureus)was used as test bacteria.The inhibition effects of Pu’er tea extract from water,75%ethanol and 95%ethanol on minimal inhibitory concentration (MIC)and minimum bactericidal concentration (MBC)were studied by paper diffusion methods.The results indicated that the Pu'er tea extract concentration within the range of 4~20 mg/mL had a strong inhibitory effect against S.aureus and the inhibitory effect increased with the concentration.95% ethanol extract on S.aureus inhibitory effect was more obvious,and both its MIC and MBC were 0.63 mg/mL.
