目的对西南乌头的根进行生药鉴定。方法采用性状鉴别和显微鉴别方法对西南乌头根(母根与子根)进行生药鉴定。结果发现西南乌头的皮层内有石细胞;母根与子根上中下各段具独立维管束,母根髓部组织常木栓化脱落中空。结论西南乌头根的显微特征明显,可作为该药材鉴定的参考依据,为进一步正确使用乌头类药材提供依据。 Objective To appraise the crude drug of southwest aconite. Methods The crude drug was identified in the acanthopanax root (root and root) of Southwest China by traits identification and microscopic identification. The results showed that there were stone cells in the cortex of southwest aconite. The upper and lower maternal roots and sub-roots had independent vascular bundles, and the cytoplasm of the root of the maternal root was ablated. Conclusion The microscopic features of aconitum root in the southwest are obvious, which can be used as the reference basis for identification of the medicinal material, which provides the basis for further proper use of aconite.
