摘　　要：采用平板生长抑制法对鼠尾藻(SargassumthunbergiiKuntze)中多酚化合物的抑菌活性进行研究。结果表明,在一定浓度范围内试样对除大肠杆菌外的受试菌均有较明显的抑菌活性,抑菌活性的大小与多酚浓度和分子质量密切相关。其中,透析内液对溶藻胶弧菌(Vibrioalginolyticus)和鳗弧菌(V.anguillarum)、透析外液对鳗弧菌和副溶血弧菌(V.parahaemolyticus)的抑制效果尤其明显。The antibacterial activity of phlorotannins from means of Plate Growth Inhibition Assay. The results showed that bacteria remarkably except Escherichia coli, and the effect Sargassum thunbergii Kuntze was investigated by the phlorotannins can inhibit the growth of tested was closely related to their concentration and molecular-weight. Among them, the inhibition of the high molecular-weight part of phlorotannins on two kinds of marine bacteria--Vibrio anguillarum and E alginolyticus, the low molecular-weight parts of phlorotannins on two kinds of marine bacteria Eparahaemolyticus and E anguillarum, were especially striking.
