一种通过快速显色筛选植物提取物的抗菌活性的方法

Identification of Antibacterial Activity of Plant Extract by A Colormetric Detection Method

目的:建立一种简单快速的显色方法筛选具有抗菌活性的植物提取物。方法:首先建立了植物提取物库,然后针对变形链球菌Streptococcus mutans和伴放线放线杆菌Actinobacillus actinomycetemcomitans进行快速染色方法筛选。结果:通过筛选发现多种植物提取物具有很强的抑菌活性。结论:本研究所建立的快速染色筛选方法简便快捷,筛选结果稳定可靠,可用于大规模的植物提取物的抗菌活性筛选。

Objective： In order to detect the antibacterial activity of a plant extract using a simple and fast colormetric detection method and identify those plant extracts with bioactivity. Methods： Firstly to set up a plant extract library and develop an antimicrobial colormetric detection method. Then, the plant extracts were tested for antibacterial activity against two species of bacteria, S. mutans and A. actinomycestemcomitans. Results： A group of plants extract with high antibacterial activity were discovered. Conclusion： The colormetric detection method can be used to screen a large plant extract library due to its fast and simple procedure.
