摘要: 探索来自18个采集地的金龙胆草RAPD遗传性分析及总黄酮成分在局群间的分布特征。采用筛选的10个随机引物,用NTSYSpc2.1软件计算材料间的Jaccard遗传相似系数(GS),并建立各种间的亲缘关系树形图,并利用紫外分光光度法测试各样品中总黄酮的含量。10个引 物共扩出71个DNA 片段,多态性 DNA 片段68个,占总扩增数的97.14%。18个金龙胆草种源可明显聚为2大类。总黄酮含量以攀枝花市范围的样品含量最高。不同种源金龙胆草间具有丰富的遗传多样性,总黄酮含量分布却与遗传聚类的分类有差异,提示今后在金龙胆草选育和道地药材研究上应该从多方面进行考虑。

Abstract: The genetic relationship of Conyza blinii Lévl. was analyzed in molecular level and the distribution characteristics of total flavonoid constituents. The RAPD method was applied to the study on Conyza blinii Lévl. from different germplasms by use of 10 random primers about 10 bp, and the parameters were calculated by NTSYSpc2.1 and the relationship was constructed based on UPGMA. Use UV spectrophotometry to test total flavonoids in each sample. 10 primers screened out from 100 primers were used for RAPD amplification. A total of 71 bands were generated, of which 68 bands were polymorphism bands. According to RAPD analysis, 18 germplasms of Conyza blinii Lévl. were classified into two categories. The genetic diversity of the 18 species in Conyza blinii Lévl. is high and the total flavinoids was related of geographic distribution.Key words: Conyza blinii Lévl.
