摘　　要：以N,N,N′,N′-四甲基,N,N′-二脱氢枞基乙醇酯二溴化铵(TDDDD)和N,N,N′,N′-四甲基,N,N′-二脱氢枞基二溴化铵(TDDD)两个系列的松香基季铵盐双子阳离子表面活性剂为材料,对它们的抑菌性能进行了测试和比较研究。结果表明,它们对所测7种菌株均具有明显的的抑制作用,其中,TDDDD系列的4个化合物对表皮葡萄球菌的抑菌作用最强,最小抑菌浓度(M IC)值为16 mg/L。由于它们较高的表面性能和特殊的结构特征,松香基双子阳离子表面活性剂具有较高的抑菌活性。Using standard serial 2-fold agar dilution method, the antimicrobial activities of N, N, N＇, N＇- tetramethyl N, N＇-diethanolamine dehydroabietate diamine dibromide （TDDDD） and N, N, N＇, N＇-tetramethyl N,N＇-didehydroabietate diamine dibromide （TDDD）, which were synthesized from dehydroabietic acid and dehydroabietylamine respectively, were determined. The bioactivity test showed that these compounds possessed good antimicrobial activities toward 7 tested bacteria. Among them, the minimal bacteriostatic concentration of 4 compounds of TDDDD against Staphylococcus epidermi- d/s were all 16 mg/L. Gemini cationic surfactants have excellent antimicrobial activity because of their higher surface activites and special structures.
