目的 探求一种准确、简便、快速鉴定金银花药材和山银花药材植物来源的方法 。方法 利用光学显微镜和扫描电子显微镜观察比较忍冬属5种植物(忍冬、华南忍冬、红腺忍冬、水忍冬、大花忍冬)的叶表皮特征。结果 在光学显微镜和扫描电镜下该属不同植物的叶表皮特征存在显著差异。结论 叶表皮特征可有效地用于金银花和山银花药材原植物的物种鉴别,并据此分别列出了光学显微镜和扫描电镜下忍冬属5种植物叶表皮特征的分种检索表。

Objective To explore an approach to identifying the plant source of Flos Lonicerae and Lonicera confusa rapidly，precisely, and efficiently.Methods Using LM and SEM to observe and compare the characters of leaf epidermis of the five species of Lonicer L. including L.japonica，L.confuse, L.hypnglauca，L.dasystyla，and L.macrantha. Results There are obvious differences in leaf epidermis among the five species of Lonicera L.under LM and SEM.Conclusion The characteristics of leaf epidermis can be used to identify the plant source of Flos Lonicerae and L.confusa. According to their characteristics under LM and SEM，the retrieval keys to the five species of Lonicera L. have been compiled.
