| 摘 要： | 薤白抑菌作用的研究结果表明:每g鲜草1ml纯水浸提液对5ml培养液的供试菌株均有抑制作用;随着浸提液稀释倍数的增加其抑菌能力减弱,32倍稀释液仅对枯草杆菌和金黄色葡萄球菌有部分抑制能力;抑菌能力强弱存在菌间差异,依次为金黄色葡萄球菌>枯草芽孢杆菌>蜡状芽孢杆菌>大肠杆菌>绿脓杆菌>沙门氏菌.此外,薤白浸提物具有较好的热稳定性,其抑菌因子尚待进一步研究.

| Abstract: | The result obtained from the study on the bacteriostasis of Allium macrostemon shows: 1g fresh grass 1 ml pure water extractive solution has the bacteriostatic effect on the 5 ml culture solution of testing bacterial strain. The effect weakens along with the increase of the dilution which has a partial inhibition effect on bacillus subtilis and staphylococcus aureus. The inhibition effect varies from one bacterium to another and it ranges as follow: Staphylococcus aureus >Bacillus subtilis>Balillus cereus>Escherichia coli>Pseuclomonas aeruginosa>Salmonella SP. In addition, the Allium macrostemon extractive has a comparatively good thermal stability. However, a further study is to be conducted concerning the bacteriostatic factor of Allium macrostemon. |
