花叶假杜鹃性状和显微鉴别

Characterization and Microscopic Identification of Barleria lupulina

目的:对爵床科植物花叶假杜鹃Barleria lupulina的地上部分进行生药学研究,为其质量标准的制定和进一步开发利用提供实验依据。方法:通过原植物鉴定、药材性状描述、石蜡切片、叶表面撕片和粉末制片等观察其形态构造。结果:花叶假杜鹃老茎圆柱形,幼茎略呈四棱形;叶柄基部有紫红色针刺;茎横切面最外层为复表皮,散布类圆形含钟乳体细胞;皮层较宽,内皮层明显,可见凯氏点;髓部宽广,含针晶;叶上下表面有含钟乳体的细胞及腺鳞,气孔直轴式。结论:上述特征可作为花叶假杜鹃性状和显微鉴别的依据。

Objective：To perform a pharmacognostical study of the part on the ground of Barleria lupulina Lindl. Method： Classical pharmacognostical methods were used to identify the source and characteristics, and the paraffin sections, temporary water tablets and slide with chloral hydrate were used to identifiy and analyse the microscopic structure. Result： The B. lupulina was characterized by slightly square stem as young and the old stem was round; there are some purple thorns in the base of petiole. The stem has multiple epidermis, broad cortex, clear endodermis and casparian dots, and some acicular crystals in its pith parenchyma cells.In both of the the upper and lower epidermis of leaf, there are some cystolith cells, glandular scales and diacytic type of stoma. Conclusion： The results can be used as evidence for characterization and microscopic identification of B. lupulina.
