为考察不同溶剂普洱茶提取物的抑菌效应,以金黄色葡萄球菌(S.aureus)为供试菌,采用滤纸片扩散法分别探讨普洱茶水提取物、75%乙醇提取物和95%乙醇提取物的抑菌效果、最小抑菌浓度(MIC)和最低杀菌浓度(MBC).研究结果表明:普洱茶提取物浓度在4~20 mg/mL范围内对S.au-reus均有较强的抑制效应,且抑制效果与浓度呈正相关.3种提取物中95%乙醇提取物的抑菌效果最佳,其MIC与MBC均为0.63 mg/mL.
為攷察不同溶劑普洱茶提取物的抑菌效應,以金黃色葡萄毬菌(S.aureus)為供試菌,採用濾紙片擴散法分彆探討普洱茶水提取物、75%乙醇提取物和95%乙醇提取物的抑菌效果、最小抑菌濃度(MIC)和最低殺菌濃度(MBC).研究結果錶明:普洱茶提取物濃度在4~20 mg/mL範圍內對S.au-reus均有較彊的抑製效應,且抑製效果與濃度呈正相關.3種提取物中95%乙醇提取物的抑菌效果最佳,其MIC與MBC均為0.63 mg/mL.

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.
