目的:为粗柄独尾草根的生药鉴定和开发利用提供科学依据。方法:应用性状、显微、薄层和紫外光谱鉴别进行鉴定研究。结果:粗茎独尾草根横切面维管束中央有较大的薄壁细胞组成的髓;粉末中导管众多,针晶散在或成束,含有大量黄色块状物。结论:其性状特征及显微特征明显,可为制定药材质量标准、研究和利用粗炳独尾草药材资源提供依据。 OBJECTIVE: To provide a scientific basis for the identification and development of crude drug for the treatment of crude stem herb. Methods: The identification, characterization, microscopic, TLC and UV spectroscopy identification were used. Results: There was a large parenchyma of parenchyma in the center of the vascular bundle of the caudal peduncle. There were many catheters in the powder, with scattered or bundled needles and a large amount of yellow lumps. Conclusion: The traits and microscopic features are obvious, which can provide basis for formulating the quality standard of medicinal materials, researching and utilizing the resources of Coprinus comatus.
