摘　　要：【目的】对市售南大青叶及其常见混伪品进行鉴别,为南大青叶药材及其中药制剂质量控制提供参考。【方法】采集南大青叶药材(野生及栽培品)及其混伪品球花马蓝叶、广西马蓝叶、路边青叶,采用性状、半显微、显微鉴定方法对其进行鉴别。【结果】南大青叶正品与混伪品在性状鉴别上的差异,主要在于叶形、叶片和叶柄的长度、叶肉颜色、叶尖端、叶缘、上下表面覆盖物及气味等;在半显微鉴别上的区别,主要在于叶柄、主脉、侧脉和叶肉上的毛茸特点及叶肉上是否能看到钟乳体等;而显微鉴别特征主要在于上下表皮细胞形状、气孔轴式、腺鳞、非腺毛及结晶的类型等。【结论】性状鉴定、半显微鉴定及显微鉴定法相结合可准确鉴别、区分南大青叶及其混伪品,为南大青叶的鉴别提供理论依据。Objective To identify the leaves of Baphicacanthus cusia （Nees） Bremek. from its commonly-seen adulterants in China markets, so as to provide a reference for the quality control of Baphicacanthus cusia and its preparations. Methods The leaves of Baphicacanthus cusia（wild or cultivated samples） and its adulterants of Strobilanthes Pentstemonoides （Nees） T. Ander（Qiuhuamalan）, Strobilanthes guangxiensis S. Z. Huang（ Guangxi Malan）, and Clerodendrum cyrtophyllum Turcz. （Lubianqing） were collected for the identification of their macroscopic, semi-microscopic and microscopic characteristics. Results Great differences of appearance characters were shown in the leaves of Baphicacanthus curia and the mixed adulterants, and the differences were mainly present in leaf shape, leaf and petiole length, leaf color, leaf apex, leaf edge, leaf surface coverings and leaf smell. The main differences of the semi-microscopic features lied in the petioles, midrib and lateral veins, fluffy characteristics of the mesophyll, and the presence of cystoliths on the mesophyll. The differences of the microscopic characteristics mainly lied in the upper and lower epidermal cell shape, shaft type stomata, adenosquamous and non-glandular hairs and crystallization types. Conclusion The combination of the macroscopic identification, semi-micro scopic and microscopic identification methods can be used for the exact identification of leaves of Baphicacanthus c usia and its adulterants, which will provide the theory basis for the identification of leaves of Baphicacanthus cusia.
