The radical scavenging activity of Laminaria japonica pigments was studied by the DPPH2,2-Diphenyl~(-1-picrylhydrazylassay. The total pigments showed a strong DPPH radical scavenging activity of 65.819% with the concentration of 0.52mg.ml~(-1). The DPPH radical scavenging activity of fucoxanthin was 19.85% with the concentration of 0.27mg.ml~(-1). The antimicrobial activity of pigment in Laminaria japonica was studied by the method of round paper. The results showed that the pigment extracts have activity against Escherichia coli, Pseudomonas aeruginosa, Saricina flava and Saccharomyes cerevisia. The antibacterial activity of total pigments for Saccharomyes cerevisia was the strongest with an inhibition diameter of 18.9 mm; and the antibacterial activity of fucoxanthin for Saricina flava was also much significant with an inhibition diameter of 10.2 mm.

测定了它们对自由基的清除率和对四种细菌的抑菌效果，研究结果表明，总色素和褐藻黄素的浓度与自由基清除率成正比，当总色素浓度为0.52mg.ml~(-1)时，清除率达到65.819%，高于陆生植物黑米色素和紫甘薯色素；当褐藻黄素浓度为0.27mg.ml~(-1)时，自由基清除率达到19.85%，低于紫苏色素、紫甘蓝色素、黑米色素、紫甘薯色素；对大肠杆菌、绿脓杆菌、八叠球菌、金黄葡萄球菌的抑菌实验结果显示，海带总色素对金黄葡萄球菌的抑菌活性最强，抑菌圈直径为18.9mm；褐藻黄素对八叠球菌的抑菌活性相对较强，抑菌圈直径为10.2mm。

In screens 20 from 100 10bp along with the machine-drawn to increase the effect to direct the thing well to carry on increases, altogether has 188 bandings,118 are the polymorphism belt, accounts for 62.8%, average each DNA polymorphism belt number which directs the thing to increase is 5.90, has promulgated the sweet potato variety heredity multiplicity; construct the shape chart called UPGMA to reflection variety diverse , will supply to try 31 variety divisions will be 4 broad headings, has promulgated between Hunan sweet potato variety from the molecular level and with the foreign country variety between sibship.

从100个10bp的随机引物中筛选出20个扩增效果较好的引物进行扩增，共产生188条带，其中118条为多态性带，占 62.8%，平均每个引物扩增出的DNA多态性带数为 5.90条，揭示了甘薯品种的遗传多样性；根据扩增结果构建出反映品种多样的UPGMA聚状图，将供试31个品种划分为4大类，从分子水平上揭示了湖南甘薯品种之间及其与外域品种之间的亲缘关系。
