性状 Description

本品根茎呈类圆形，多弯曲，有分枝，长10～30cm，直径0.1～1cm。表面灰棕色，具细纵纹；节膨大，节上长有细根或茎残基；外皮易剥落，呈蓝灰色。质硬而脆，易折断，断面不平坦，皮部蓝灰色，木部灰蓝色至淡黄褐色，中央有髓。根粗细不一，弯曲有分枝，细根细长而柔韧。气微，味淡。
Rhizomes and roots are nearly cylindrical, often curved, branched, 10-30 cm long, 0.1-1 cm in diameter; surface grayish-brown, with fine longitudinal wrinkles; nodes swollen, with fine roots or stem remnants; outer bark easily peeled off, bluish-gray; texture hard and brittle, easily broken; fractured surface uneven, bark bluish-gray, wood grayish-blue to pale yellowish-brown, with pith in the center; roots vary in thickness, curved and branched, fine roots long and flexible; odor slight; taste bland.

鉴别 Identification

（1）本品根茎横切面：木栓层为数列细胞，内含棕色物。皮层宽广，外侧为数列厚角细胞；内皮层明显；可见石细胞。韧皮部较窄，韧皮纤维众多。木质部宽广，细胞均木化；导管单个或2～4个径向排列；木射线宽广。髓部细胞类圆形或多角形，偶见石细胞。薄壁细胞中含有椭圆形的钟乳体。
（1）Transverse section of rhizome and root: cork composed of several layers of cells, containing brown substances. Cortex wide, outer side composed of several layers of thick-walled cells; endodermis distinct; stone cells visible. Phloem relatively narrow, with numerous fibers. Xylem wide, cells all lignified; vessels solitary or 2-4 arranged radially; xylem rays wide. Pith cells nearly circular or polygonal, occasionally with stone cells. Thin-walled cells containing elliptical raphides.

（2）取本品粉末2g，加三氯甲烷20ml，加热回流1小时，滤过，滤液浓缩至2ml，作为供试品溶液。另取靛蓝对照品、靛玉红对照品，加三氯甲烷制成每1ml各含0.1mg的混合溶液，作为对照品溶液。照薄层色谱法（通则0502）试验，吸取上述两种溶液各20μl，分别点于同一硅胶G薄层板上，以石油醚（60～90℃）-三氯甲烷-乙酸乙酯（1∶8∶1）为展开剂，展开，取出，晾干，立即检视。供试品色谱中，在与对照品色谱相应的位置上，显相同的蓝色和紫红色斑点。
（2）To 2 g of the powder add 20 ml of chloroform, heat under reflux for 1 hour, filter, evaporate the filtrate to 2 ml, and use it as the test solution. Prepare a mixed solution containing 0.1 mg of indigo carmine CRS and 0.1 mg of indigo carmine red CRS in 1 ml of chloroform as the reference solution. Carry out the method for thin layer chromatography<0502>, using silica gel G as the coating substance and a mixture of petroleum ether (60-90°C), chloroform, and ethyl acetate (1:8:1) as the mobile phase. Apply separately to the plate 20 μl of each of the above two solutions. After developing, remove the plate, dry in air, and examine immediately. The blue and purple-red spots in the chromatogram obtained with the test solution correspond in position and color to the spots in the chromatogram obtained with the reference solution.
