目的:研究一点红药材的鉴别方法和质量标准。方法:使用原植物鉴别、性状鉴别、显微鉴别和薄层色谱进行鉴别研究。结果:一点红叶下表皮细胞垂周壁波状弯曲,气孔不定式;粉末可见花粉粒、非腺毛等。薄层色谱鉴别可见槲皮苷斑点。结论:确立了一点红药材简便、有效的鉴别方法,为一点红药材的质量标准制订提供了科学依据。 Objective: To study the identification method and quality standard of reddish medicine. Methods: The identification of the original plant, traits identification, microscopic identification and thin layer chromatography identification studies. Results: The erythrocyte epidermis cells wavy anticlinal wall, infiniform stomatal; powder visible pollen grains, non-glandular hair and so on. Thin layer chromatography identified quercetin spots. Conclusion: The method of identifying the red drug is simple and effective, which provides a scientific basis for the quality standardization of red drug.
