黄芪为豆科植物膜荚黄芪 Astragalusmembranaceus(Fisch)Bunge 及内蒙黄芪 A.mongholicus Bunge 的干燥根。1984年我单位从安徽购进一批黄芪,经初步鉴定为我市规定的黄芪伪品——豆科植物蓝花棘豆 Oxytropia Caerulea(Pall.)DC.的根,其外形与黄芪极为相似,为防止误收误用,现将该伪品的鉴别特征介绍于下,供同道参考。一、性状根头部略膨大,呈园柱形。长约20～50cm,直径约0.5～2cm,有分枝,微扭曲,表面灰黄色或黄棕色,有纵皱纹,部分外层薄皮去除呈棕红色,栓皮易脱
Astragalus membranaceus is a dry root of Astragalusmembranaceus (Fisch) Bunge and A. mongholicus Bunge. In 1984, our company purchased a batch of Astragalus roots from Anhui, and it was initially identified as the root of the Oxytropia Caerulea (Pall.) DC, a forgery of Astragalus that is prescribed by our city. Its appearance is very similar to that of Astragalus membranaceus. In order to prevent misuse and misuse, the discriminating features of the counterfeit goods are introduced below for reference. First, the head of the trait is slightly enlarged, showing a cylindrical shape. About 20 to 50cm in length, 0.5 to 2cm in diameter, branched, slightly twisted, yellowish-brown or yellow-brown on the surface, longitudinal wrinkles, brownish red on some thin outer skin, easy to remove the cork
