A comparative study on the histological and morphological characteristics and the intrinsic quality of the roots of Huabei Qianhu(Peucedanum harry-smithii)，Shaomao BeiQian hun(P.harry-smithii var.subglabrum)and Baihua Qianhu(P.praeruptorum)was carried out, Results revealed that the former two Qianhu produced in Gansu are similar to Baihua Qian hu in their main ingredients.Thus the two Qianhu are worthy for further research and develo pm ent,At the same time, it was observed that Baihua Qianhu Produced in Ganau is of inferior quality and the content of EtOH extract of its root is slightly lower than that from elsewhere in China.
