摘　　要：目的对桫椤叶进行生药学研究,为桫椤叶的开发利用提供参考依据。方法采用原植物鉴定、显微鉴别和薄层鉴别方法。结果描述了桫椤叶的性状、粉末显微特征、成分预试以及薄层鉴别结果。结论该研究为桫椤叶的深入研究和开发利用提供了理论依据和参考。Alsophila spinulosa （Hook.）Tryon is one of the only existing woody ferns which is extremely started. It protected by many countries as an endangered plant. In this paper,the shape properties ,microscopical feature,physical and chemieal appraise of Alsophila spinulosa were studied by pharmacognosy method, such as their physicochemical characteristics were identified by using thin layer chromatography（TLC）. Thus,it can be taken as the establishment of quality standard,pharmacognostic studies and the fur- ther utilization of the leaves of Alsophila spinulosa（Hook. ） Tryon through the study on their pharmacognostic characteristics.
