本品根茎顶端有数个分枝，有密集横环纹，其上有叶柄残基。根圆柱形，长5～16 cm，直径0.6～1.5 cm。表面黄棕色至灰黄褐色，粗糙，有明显的皱纹和纵沟。质松泡，易折断，断面不整齐，皮部淡棕色至黄棕色，木部淡黄白色至浅黄棕色，周边与中心部呈灰白与黄色相间的花纹。气微香，味微苦。
Rhizome with several branches at the top, with dense annular wrinkles and leaf stalk remnants. Root cylindrical, 5-16 cm long, 0.6-1.5 cm in diameter. Surface yellow-brown to grayish-brown, rough, with obvious wrinkles and longitudinal grooves. Texture spongy, easily broken, uneven fracture. Cortex pale brown to yellow-brown, wood pale yellow-white to light yellow-brown, with gray-white and yellow patterns alternating between the periphery and the center. Odour, slightly fragrant; taste, slightly bitter.
鉴别 Identification
（1）根横切面：木栓层为10数列，栓内层狭窄，细胞多数皱缩。韧皮部宽广，射线明显，在射线处具较大的分泌腔；束中形成层细胞数列或不明显，呈断续环状。木质部由导管、射线、木纤维组成，导管稀少。
（1）Transverse section of the root: cork layer with 10 or more rows, narrow inner cork layer, and most cells wrinkled. Cortex broad, with distinct rays and larger secretory cavities at the rays; central cylinder with cells arranged in rows or discontinuous rings. Xylem composed of vessels, rays, and wood fibers, with few vessels.
（2）取本品粉末1 g，加三氯甲烷10 ml，超声处理30分钟，滤过，滤液浓缩至1 ml，作为供试品溶液。另取高山辣根菜对照药材1 g，同法制成对照药材溶液。照薄层色谱法（通则0502）试验，吸取上述两种溶液各10 μl，分别点于同一硅胶G薄层板上，以环己烷-乙醚-乙酸乙酯（20∶5.5∶2.5）为展开剂，展开，取出，晾干，喷以30%硫酸乙醇溶液，在105 ℃加热至斑点显色清晰。供试品色谱中，在与对照药材色谱相应的位置上，显相同颜色的斑点。
（2）To 1 g of the powder add 10 ml of chloroform, treat with ultrasound for 30 minutes, filter, evaporate the filtrate to 1 ml, and use as the test solution. Prepare a solution of 1 g of Pegaeophyton Radix et Rhizoma as the reference solution using the same method. Carry out the method for thin layer chromatography <0502>, using silica gel G as the coating substance and a mixture of cyclohexane-ether-ethyl acetate (20: 5.5: 2.5) as the mobile phase. Apply separately to the plate 10 μl of each of the above two solutions. After developing and removal of the plate, dry in air. Spray with a 30% solution of sulfuric acid in ethanol, heat at 105 °C to the spots clear. The spot in the chromatogram obtained with the test solution corresponds in position and colour to the spot in the chromatogram obtained with the reference solution.
