摘　　要：目的中药葛根栽培品与野生品药材性状显微组织差异比较。方法药材性状比对,根横切面、粉末显微特征测量和比对。结果葛根野生品与栽培品药材性状区别:野生葛根呈长圆柱形,直径1～6cm,切面呈棕褐色,纤维性;栽培葛根呈长纺锤形,直径2～12cm,显粉性。显微组织方面区别表现在:葛根野生品根横切面晶鞘纤维束众多,有多层切向排列的分泌道群,木质部导管粗大,排列密集,淀粉粒较少;栽培品晶鞘纤维束、分泌道群均较少,木质部导管排列稀疏,径向排列,淀粉粒众多。结论葛根栽培品与野生品在药材性状和显微组织上存在一定差异,外观性状的差异和根横切面晶鞘纤维束、导管和淀粉粒的多少和大小,可以做为两者的鉴别特征。Objective To indicate the difference shapes, properties and the microscopic frameworks of wild and cultivated Radix Puerariae. Methods Comparing the shapes and properties , measuring and comparing the microscopic characters of transverse section and the powder and disintegrated tissue of roots. Results For the shapes and properties, wild Radix Puerariae has long - column shape with the diameter of 1- 6 cm and deep brown fibre section. Cultivated Radix Puerariae has long - spindle shape with diameter of 2 - 12 cm and light brown powder section. For the microscopic frameworks, the root transverse section of wild Radix Pueraria has much crystal fiber bundle with muhilayer,the vessel of xylem is crassitude with dense ranks and a few starch grain, the root transverse section of the cultivated has a few crystal fiber bundle and a few groups of secretory tube, the vessel of xylem has radial ranks with much starch grain. Conclusion Wild Radix Puerariae and cultivated Radix Puerariae have differences shapes and properties and the differences of microscopic frameworks. The main characteristics of them are the different shapes and properties and the different size of xylem vessel and different number of groups of secretory tube and starch grain.
