采用醇提法从襄麦冬中提取其主要有效成分黄酮类化合物并通过滤纸片法对3种浓度0.5、1.0、2.0 mg/mL的襄麦冬黄酮提取液进行抑菌试验。结果表明，邦戈尔沙门氏菌的抑菌圈直径分别为（15.200±0.361） mm，（18.167±0.451） mm和（22.433±0.306） mm。而大肠杆菌的的抑菌圈的直径分别为（11.500±0.361） mm，（13.600±0.500） mm，（16.700±0.400） mm。可见，3种不同浓度的麦冬总黄酮溶液对邦戈尔沙门氏菌和大肠杆菌均具有抑制作用，并且具有剂量依赖性。在相同浓度下，邦戈尔沙门氏菌对麦冬总黄酮提取物的敏感性比大肠杆菌强。%General flavones from Liriope spicata Lour. var. prolifera Y. T. Ma was extracted through alcohol ex-traction and bacteriostatic experiments of different concentrations 0.5, 1.0, 2.0 mg/mL general flavones ex-tracts was performed by the method of filter paper. Bacteriostatic ring diameter of Salmonella Bongor were (15.200 ± 0.361) mm,(18.167 ± 0.451) mm and (22.433 ± 0.306) mm respectively, and the diameter of Es-cherichia coli were(11.500 ± 0.361) mm,(13.600 ± 0.500) mm,(16.700 ± 0.400) mm respectively. All the three different concentrations general flavones extracts showed inhibitory effect on both Salmonella Bongor and Escherichia coli with a dose-dependent manner. At the same concentration, Salmonella Bongor was more sensi-tive to general flavones extracts than Escherichia coli.
