摘　　要：目的:为玉郎伞鉴别和开发利用提供依据。方法:显微鉴定和紫外吸收光谱。结果:发现玉郎伞有明显的鉴别特征:根的横切面中皮层有石细胞群和纤维束,断续成环;粉末中晶鞘纤维、具缘纹孔导管多见;粉末乙醇液在261、216、204±1nm波长处有吸收峰,而氯仿液在262±1nm波长处有吸收峰。结论:以上特征可作为鉴别玉郎伞的依据。Objective: To provide evidences for the identification of Millettia pulchra Kurz var. Laxior (Dunn)Z. Wei. Method: Microscopic and UV identification. Result: Obvious identificational character was found, fox example, there are stone cell groups and fiber bundles arranging with ring unconti9nously in cortex; there are fibers containing square crystals in the powder; the EtOH solution of the powder has absorbing peaks in 261, 216, 204 ?1 nm wave length, and the CHCl3 solution 262 ?1 nm wave length. Conclusion: The character provided evidences for the identification of Millettia pulchra Kurz var. Laxior(Dunn) Z. Wei.
