摘要:

用菊苣茎乙醇提取物,以四种细菌和四种真菌作为靶标菌进行体外抑菌实验。结果显示该提取物对细菌和真菌均有一定的抑制作用,其中对苏云金杆菌和根霉菌的抑菌作用不太明显。热处理对提取物的抑菌作用无影响,在较宽的pH 范围内均有抑菌作用。

关键词: 菊苣, 乙酸提取物, 抑菌活性

Abstract:

Active substances extracted from Cichorium intybus L. stems with 95% ethanol were subjected to analysis of antimicrobial activities against four species of fungi and four species of bacteria by filter paper disc agar diffusion technique. Results showed that the extract had broad-spectrum antimicrobial activities against fungi and bacteria and the activities increased with the increasing concentration of extract. However, no effects were observed against Bacillus thuringiensis and saprophytic fungus (Rhizopus sp.) The extract possessed lower minimum inhibitory concentrations when compared to commercial antipreservatives, such as sodium benzoate and potassium sorbate. It exhibited high thermal stability and high antimicrobial capacities within a wide range of pH without pH adjustment for food.

Key words: Cichorium intybus L., ethanol extracts, anti-microbial activities
