白眉草是广东、广西等地的地方习用药材,有与白薇相似的清热解毒,凉血利尿之功效。为区分白眉草与白薇的药材性状和组织学特征,通过对白眉草的性状、根横切面、叶横切面、全草粉末显微组织的观察,获得其性状及组织学鉴别特征,为制定广东习用药材质量标准及进一步对其进行生药学研究,并与白薇鉴别奠定了基础。
White eyebrow is a local herbal medicine in Guangdong, Guangxi and other places. It has the similar functions of clearing heat and detoxifying and cooling blood and diuresis. In order to distinguish between medicinal and histological characteristics of E. urophylla and B. virginica, the traits, histological cross-sections, cross-sections of leaves, and whole-grain powder microstructures were observed to obtain traits and histological identification characteristics. The quality standards for traditional Chinese medicinal materials in Guangdong and their further research on pharmacogenetics laid the foundation for identification with Bai Wei.
