摘要: 榉属植物体内酚类、多糖等次生物质含量较高, 严重影响从中提取总DNA 的产量和质量。针对这一问题探索出一种适合榉属植物总DNA 的提取方法, 并对提取的总DNA 进行了纯度和浓度的鉴定。结果表明此方法可有效去除次生物质对DNA 的干扰, 样品DNA 的质量和纯度较高, 可用于随机引物RAPD 扩增和随后的各种遗传学分析。

Abstract: The content of phenolic compound, polysaccharides and other secondary metabolites is high in ligneous plant, which influences frequently the yield and quality of genome DNA when being extracted.In this study, a new method was introduced which do best for characterization the purity and concentration of genome DNA.The result showed that it could effectively eliminate the affections of the secondary materials to extracted genome DNA from Zelkova, and which be suitable for RAPD analysis and other geneticanalysis.

Key words: Zelkova, extraction of genome DNA, RAPD
