【摘要】 该文用滤纸圆片法和分光光度法研究了尼泊金酯等防腐剂在中性条件下对3种常见细菌的抑制作用。结果表明,苯甲酸钠和山梨酸钾在中性条件下对细菌的抑制很弱,双乙酸钠和脱氢醋酸钠的抑菌效力也较弱,尼泊金酯的抑菌性较好,尤其是丁酯和庚酯。

【Abstract】 The inhibition effect of Nipagin esters on three kinds of bacteria in neutral culture medium was studiec by means of filter paper disks and spectrophotometric investigation. The inhibition of Sodium Benzoate and Potassium Sorbate has not bacteriostatic action on the three strains. The inhibition of Sodium diacetate and Sodium dehydroacetate is feebleness. The inhibition of Nipagin esters is strong on the bacteria in neutral culture medium,especially Butyl-p -hydroxybenzoate and Heptyl-p -hydroxybenzoate.
