| 摘 要： | 为探明DNA提取过程中去除多糖的有效方法,以丁香属3种植物为材料,用3种DNA提取方法（普通CTAB法、氯苯法和高盐法）提取丁香属植物基因组DNA。对提取的DNA质量采用琼脂糖凝胶电泳和紫外分光光度计法进行检测,并采用蒽酮硫酸法测定DNA提取过程中多糖含量的变化。结果表明：3种方法的多糖去除率相近且都比较高。高盐法与前两种方法相比对人体和环境危害较小且操作简单,是最适合该属植物的DNA提取方法。该方法采用了专门的去除多糖的步骤,为DNA提取过程中多糖的去除提供了一定的理论依据。

| Abstract: | To find an efficient method for the removal of polysaccharide in plant DNA extract process,the CTAB,high salt and Chlorobenzene methods were used to extract the genome DNA of three Syringa plants.Agarose gel electrophoresis and ultraviolet spectrophotometer methods were adopted to test the DNA quality,and the concentration changes of polysaccharid in the DNA extraction process were tested with anthraquinone hydrate-sulfuric.The result showed that the removal efficiency of polysaccharide in the three methods... |
