五倍子提取物对海洋污损菌的抑制作用

The Inhibitory Effect of Extracts from Galla Chinensis on Marine Fouling Bacteria

目的:体外试验观察五倍子不同极性部分提取物对海洋污损菌的抑制活性。方法:平皿孔穴法。结果:五倍子乙酸乙酯、乙醇、水提取物对海洋中假单孢菌属、气单孢菌属、产碱菌属、黄杆菌属、弧菌属、发光杆菌属、莫拉氏菌属、色杆菌属、肠杆菌属等9个菌属均表现出较强的抑制活性,五倍子的石油醚与氯仿部分排除误差没有活性。结论:五倍子乙酸乙酯、乙醇、水提取物对上述9个菌属呈较高的体外广谱抗菌活性,为寻找新型的生物环保型防污材料以及进一步研究提供了理论依据,开拓了中药研究的新领域。

Objective:To observe the activity of extracts from Galla Chinensis with different solvents against marine fouling bacteria in vitro. Method: Incubating plate with foveolae was used. Results:The ethyl acetate, ethanol and water extracts showed strong inhibitory activity a-gainst marine fouling bacteria belonging to nine genera including Pseudomonas, Aeromonas , Alealigenes,Flavobacterium, Vibrio , Photobacteri-um, Moraxella, Chromobacterium, Enterobacter. While, the petroleum ether and chloroform extracts showed no inhibory activity. Conclusion: The study provided theory basis for new biologic protective dope on environment.
