摘　　要：[Objectives]This study was conducted to identify the microscopic characteristics of Chenopodium album L.[Methods]The microscopic identification method was adopted.[Results]The xylem vessels and fiber bundles of the roots are arranged into 3-4 intermittent ring belts in a concave-convex pattern,alternately with the parenchymal cell ring belts;and the xylem rays vary in width.The cross section of the stems is polygonal;there are parenchyma cells at the corners of the cortex;there are many vascular bundles of varying sizes;and calcium oxalate clusters are common in the medulla and cortex.There are 2 to 4 vascular bundles in the main leaf vein,peltate;and fiber bundles exist below the phloem.The powder is characterized by numerous clusters of calcium oxalate,which are uniform in size,sharp at edges and corners.[Conclusions]This study can provide reference for the identification and quality standard of the crude drug.
