| 摘 要： | 研究了桑叶水煎剂对常见微生物的抑菌作用,以及在不同pH值条件下的抑菌效果.结果表明:提取液对霉菌的生长没有明显的抑制作用;对供试细菌有效,其中对微球菌的抑制最强,其次为沙门氏菌和大肠杆菌,对枯草芽孢杆菌的作用较弱.抑菌效果随着桑叶水煎剂浓度的增加而加强.在酸性条件下,桑叶水煎剂的抑菌作用都有不同程度的增加,但效果均不如0.05%苯甲酸钠.

| Abstract: | The bacteriostasis of water extracts from mulberry leaf was investigated.The result showed that water extracts of mulberry leaf could inhibit the growth of the common bacteria in food including Microaroccus,Escherichia coli,Salmonellasp and Bacillus subtili, but had not remarkable effect on mold including Aspergillus,Penicilliam,Mucorracemosus,and Rhizopus nigricans. The effectiveness of water extracts from Mulberry leaf increased with extracts concentrations increased or pH decreased.However,the inhibitions of extracts from mulberry leaf were weaker than that of 0.05% sodium benzoate,which is a chemical bacteriostatic agent used widely in food products. |
