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.
