    Abstract:

    Objective To identify the traditional Chinese medicine Cirsium japonicum from its two adulterants on the market. Methods Microscopic characteristic identification was used to observe Cirsium japonicum and its adulterants. Results The stems and leaves of Cirsium japonicum had cobwebby hair and long multicellular hairs, with hairs on both sides and margin of bracts and hairs on the filaments, the apex of the anther had the shape of long triangle, and the top of pappus expanded to a spindle shape or gradually became thinner. The stems and leaves of Cirsium setosum (Willd.) MB. had cobwebby hair, with no hairs in the inner side of bract, the apex of the anther was sharp, and the top of pappus gradually became thinner. Sonchus asper (L.) Hill had no hair on the stems, leaves, and bracts, the filaments were smooth, the apex of the anther was black, the corolla was covered with long hair, and the edge of fruit was jagged. Conclusion Microscopic characteristic identification can accurately and quickly identify Cirsium japonicum from its adulterants.
