目的:建立广防风形态学及理化鉴别方法,完善质量标准。方法:考证广防风文献,应用植物分类学、药材鉴定学及薄层色谱的方法对广防风生药学鉴别特征观察记述,对不同产地广防风根及地上部位化学特征比对研究。结果:广防风本草考证表明古今广防风为唇形科植物广防风Epimeredi indica(L.)Rothm.干燥全草。本文提供广防风植物形态,根和茎叶性状特征,提供其组织横切面及粉末的特征,同时提供广防风地上与地下部位成分定性分析结果。结论:研究结果可为广防风的鉴别、质量标准制订及合理开发利用提供依据。
Objective: To establish a broad-based wind morphological and physical and chemical identification methods to improve the quality standards. Methods: The textual research on the broad-leaved winds was carried out. By using plant taxonomy, medicinal identification and thin-layer chromatography, the identification and identification of the characteristics of Guangfeng wind-blown pharmacy were described and compared. Results: The study of Guangfengfengbencao showed that the ancient and modern Guangfeng was the dried herb of Epimeredi indica (L.) Rothm. This paper provides the morphological characteristics of broad-leaved wind plants, the characteristics of roots and stems and leaves, and provides the cross-section and powder characteristics of their tissues. At the same time, it provides the qualitative analysis results of the composition of broad-leaved and underground parts. Conclusion: The results of this study can provide the basis for the identification of Guangfeng wind, establishment of quality standards and rational development and utilization.
