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.
目的
基于nrDNA ITS序列解释紫花前胡分类地位修订的分子证据。
方法
PCR扩增、DNA测序和分支分析。
结果
获得了5种当归属和前胡属植物的ITS序列及系统发育树，其中5种植物分为当归组和前胡组，紫花前胡归为当归组。
结论
紫花前胡应归属于当归属，其学名应修订为紫花当归。紫花当归和白花前胡应分别作为药材使用。
