| 中文摘要:目的 对滇南金线兰进行生药鉴定，明确其原植物形态和显微特征。方法 采用生药学鉴定方法，观察滇南金线兰的原植物形态、组织构造及粉末显微特征。结果 叶片呈卵形或卵状披针形，具金红色叶脉，花不倒置，唇瓣黄色，呈Y字形，前部明显扩大并2裂，裂片狭长圆形或狭倒披针形，中部收狭成长10 mm左右、其边缘具狭翅。显微结构中，根、茎横切面中皮层明显，具草酸钙针晶、黏液细胞等；叶横切面上表皮细胞乳突状，下表皮气孔类型多样，以不定式气孔为主。粉末中可见草酸钙针晶和导管。结论 滇南金线兰的生药鉴定为其资源开发利用提供了参考依据。 |

| Abstract:Objective To identify the crude drugs of Anoectochilus burmannicus, and clarify its original plant pharmacognostical and microscopic characteristics. Methods The pharmacognostical identification method was used to observe the original plant, tissue structure and microscopic characteristics of A. burmannicus. Results Leaves were ovate or ovate elliptic with golden-red veins. Non-inverted yellow flowers had Y-shaped and yellow labellum, which were anteriorly enlarged and 2-lobed. The lobes were narrowly oblong or narrowly oblanceolate. The middle part of labellum was narrow to form a 10 mm long structure with margin narrowly winged. In the microscopic structure, the cortex is obvious in the cross sections of root and stem, together with needle crystals of calcium oxalate and mucous cells. The upper epidermal cells on the cross section of the leaves were papilloid in shape, whereas diverse stomas existed among the lower epidermal cells, with anomocytic stomas as the major type. Needle crystals of calcium oxalate and conduits can be found in the powder. Conclusion These data provide a reference for the identification and resource development and utilization of A. burmannicus. |
