摘　　要：目的对滇产白及、黄花白及和小白及药材进行鉴别,建立3种滇产"白及"的对比鉴别方法。方法应用性状与显微鉴别方法,着重对药材表面特征、横切面及粉末等显微特征等进行研究。结果滇产白及与其习用品黄花白及、小白及在药材性状、显微特征上具有较高的相似性,同时找出了三者间的明显差异;应用性状与显微鉴别方法可以很好的鉴别三种习用品。结论黄花白及与小白及有其习用的合理性,应对二者的安全性、药效等进行深入研究,为资源的保护和利用提供依据。本文建立了一套利用性状和显微特征鉴别三种滇产"白及"的方法,可有效应用于相关药材的鉴别研究。Objective： To identify bletilla striata in Yunnan,Huanghua bletilla striata and small bletilla striata and to establish the comparative identification method for three types of bletilla striata growing in Yunnan. Methods： Traits of application and methods of microscopic identification were investigated,mainly focusing on surface characteristics of herbs,cross sections,powder and other characteristics in microscopy. Results： There was a high similarity in traits and microscopic characteristics among bletilla striata in Yunnan,Huanghua bletilla striata and small bletilla striata,while significant difference could be found,so that the three types of bletilla striata could be identified by traits of application and microscopic characteristics. Conclusion： The deep investigation of rationality,safety and efficacy of Huanghua bletilla striata and small bletilla striata can lay the evidence for protection and utility of resources. Our paper is to introduce a set of methods to identify the ＂bletilla striata＂by using the traits and microscopic characteristics,which can be effectively applied to the identification of related medical materials.
