摘　　要：目的:比较不同产地赤芍及其栽培品的药材性状、显微特征差异。方法:赤芍的药材性状及其显微组织特征比对,显微数量分析方法。结果:不同产地的赤芍比较显示,道地产地多伦产赤芍呈圆柱形,并较其他产地药材直而长,外皮具排列紧密的纵沟纹,较易剥落,断面粉白色;根的横切面导管切向排列,并与木纤维束整齐交互排列;木纤维束由4～19个纤维组成。赤芍的栽培品与野生品药材性状、显微组织方面的差异表现为:栽培品的根呈圆锥状,须根多,外皮较平滑,气味弱;根横切面栽培品导管的排列方式与野生品不同,栽培1～2年的根导管稀疏,径向排列,三、四年生的外侧导管呈团块排列;五、六年生的根外侧导管有切向排列;赤芍栽培品淀粉粒较多,单位观察面积数量2656个/mm2,草酸钙簇晶数量较少,27个/mm2;而野生品的淀粉粒数量较少,1791个/mm2,草酸钙簇晶较多,72个/mm2。结论:道地药材多伦赤芍与其他产地药材略有差异,可以根据其外观形态和木纤维束情况区别其他产地赤芍。赤芍野生品和栽培品在药材性状和显微组织上存在差异,外观性状的差异、根横切面导管的排列方式和单位面积草酸钙簇晶和淀粉粒的数目,可作为两者的鉴别特征。Objective：To compare pharmacognostic characteristics and microscopic characteristics of Radix Paeoniae Rubra （chishao） from different areas. Method： Pharmacognostic characteristics and microscopic characteristics of Radix Paeoniae Rubra were compared by microscope count methods. Result：Chishao in duolun was more straighter and longer, cortex with a set of closely spaced rill, peel off easily, pink section, etc. The wild chishao were different from the cultivated chishao on pharmacognostic characteristics and microscopic characteristics, such as appearance shape, smell, vessel arrangement, and number of crystal and starch in unit area. Conclusion： Chishao in duolun were different form others, appearance shape, wood fiber, difference of appearance shape, vessel arrangement, and number of crystal and starch in unit area can be used as identificatin feature of the wild chishao and the cultivated chishao.
