摘　　要：目的:从核DNA ITS序列角度阐明紫花前胡分类位置修订的分子基础。方法:PCR扩增、DNA序列测定、分支分析法进行研究。结果:得到紫花前胡、白花前胡、白芷、泰山前胡、骨缘当归的ITS序列和系统发育树,其中紫花前胡和白芷、骨缘当归聚为一组,泰山前胡和白花前胡聚为另一组。结论:紫花前胡应为当归属植物,紫花前胡和白花前胡应分别入药。Objective： To explain the molecular evidence of revision of taxonomic placement of Peucedanum decursivum based on the nrDNA ITS sequence. Method： PCR amplification, DNA sequencing and cladistic analysis. Result： The ITS sequences and phylogenetic tree of 5 species of Angelica were and Peucedanum were acquired, in which 5 species were divided into 2 groups, Angelica group and Peucedanum group. P. decursivum was placed in the Angelica group. Conclusion：P. decursivum belongs to genus Angelica. The scientific name of P. decursivum should be revised as A. decursivum. A. decursivum and P. praeruptorum should be used as crude drug respectively.
