目的:研究喉咙草的性状及显微特征。方法:对喉咙草的根、总花梗和叶进行详细的生药鉴定。结果:喉咙草的显微特征明显,有大量非腺毛和腺毛。其中腺毛有2种,一种腺头、腺柄均为单细胞;另一种腺头为单细胞,腺柄由2～3个细胞组成。导管多为网纹、螺纹导管。气孔为不定式。结论:上述特征可作为喉咙草的鉴别及质量标准制定的参考依据。
Objective: To study the traits and microscopic characteristics of the throat grass. METHODS: Detailed crude drug identification was performed on the roots, peduncles and leaves of L. lucidum. RESULTS: The microscopic features of L. lucidum were apparent, with a large number of non-glandular and glandular hairs. There are 2 kinds of glandular hairs, one glandular head and glandular stems are single cells; the other glandular head is single cells, and the gland stem is composed of 2 to 3 cells. The catheters are mostly textured and threaded catheters. Stomatal is infinitive. Conclusion: The above characteristics can be used as a reference for the identification of throat grass and the establishment of quality standards.
