| 摘 要： | 研究了委陵菜提取液对4种细菌的抑制作用.结果表明:委陵菜提取液能有效地抑制细菌的生长,对供试菌的最低抑菌浓度金黄色葡萄球菌为6%,大肠杆菌为10%,枯草芽孢杆菌为8%,变形杆菌为12%.委陵菜提取液经121℃湿热条件处理20min仍具有一定的抑菌效应,说明委陵菜提取液具有较强的热稳定性.而且委陵菜提取液对葡萄有一定的保鲜作用.

| Abstract: | Effects of Potentilla chinensis Set extracts on four kinds of bacterium were studied by the method of filter paper. The results showed that the growth of four kinds of bacterium could be inhibited effectively. Potentilla chinensis Set extracts could still inhibit bacterium growth after being heated under 121 ~C for 20 rain, which indicated that the extracts had strong thermal stability. Meanwhile, Potentilla chinensis Set extracts also had a certain fresh-keeping effect on grapes. |
