对北豆根及其混淆品绵毛马兜铃的根茎,从形态特征、显微鉴别、理化鉴别等方面进行了比较,证明两者有明显的不同,不能混用。 The rhizomes of M. frondosa and its adulterants, M. edulis, were compared in terms of morphological characteristics, microscopic identification, physical and chemical identification, and so on, which proved that there were obvious differences between the two and could not be mixed.
