目的 为用药准确和进一步开发利用该植物资源、制订药材标准提供依据。 方法 直观鉴别、显微鉴别、理化鉴别相结合, 并对能否扩大药用部位进行初步探讨。 结果 鉴别特征突出四点:1块茎呈肾形弯曲。 2薄壁细胞多边形, 排列紧密间隙小。 3淀粉复粒较多。 4含草酸钙针晶。块茎在紫外吸收光谱波长241nm处有明显的吸收峰, 不定根则没有。结论 鉴别特征明显、易掌握; 块茎入药时必须去除其上的不定根。

[Abstract]
Object To provide a basis for the further development, proper utilization and for mulation of a standard for the medicinal materials. Methods By macro and microscopic studies in combination with physicochemical identification. The possible therapeutic value of other parts of the plant was briefly dis-cussed. Results Four obvious distinctive features were observed:①.Stem tuber showed a curved kidney like shaped.②.Parenchymatous cells were polygonal shaped and densely packed together with limited in-tercellular spaces.③. Rich in compound starch grains, and ④. Crystalline calcium oxalate. Clusters can be seen. The tubers had an absorbance peak in UV specturm at λ241nm, but its adventitious root was devoid of such absorbance peak.Conclusion The distinctive features are clear and can be mastered easily. The adventitious roots must be discarded when the tubers were used as medicine.
