OBJECTIVE
To evaluate the pharmacognostic characters of an important medicinal plant, Holoptelea integrifolia (H. integrifolia) Roxb.
METHODS
The pharmacognostic studies were carried out in terms of organoleptic, microscopic, macroscopic and fluorescence analysis.
RESULTS
The characteristic microscopic features of leaves were observed as trichomes, multicellular trichomes, xylem cells, phloem cells, collenchyma, vascular bundles, spongy parenchyma and palisade cells. The characteristic microscopic features of root bark included cork cambium, primary cortex, phloem fibers, medullary rays, endodermis, pericycle and lignified fibers in the transverse section and longitudinal section. The characteristic microscopy of root bark powder showed the presence of cortex cells, sieve tubes, calcium oxalate crystals and lignified fibers. Macroscopic study showed that leaf shape-oval, apex-acute, base-cordate and leaf margin was entire with glabrous surface, bitter taste and characteristic odour. The morphological features of root bark showed deep fissured, rough and firm surface with rhitydome and the periderm parallel to cambium.
CONCLUSIONS
Various pharmacognostic characters observed in this study help in the identification and standardization of H. integrifolia.
目的
评价一种重要药用植物全缘叶波罗蜜（Holoptelea integrifolia (H. integrifolia) Roxb.）的生药学特征。
方法
从感官、微观、宏观和荧光分析方面进行生药学研究。
结果
叶片的特征性微观特征观察到有毛状体、多细胞毛状体、木质部细胞、韧皮部细胞、厚角组织、维管束、海绵状薄壁组织和栅栏细胞。根皮的特征性微观特征在横切面和纵切面包括木栓形成层、初生皮层、韧皮纤维、髓射线、内皮层、中柱鞘和木质化纤维。根皮粉末的特征性显微镜观察显示有皮层细胞、筛管、草酸钙晶体和木质化纤维。宏观研究表明，叶片形状为椭圆形，先端尖，基部心形，叶缘全缘，表面无毛，味苦涩，有特征性气味。根皮的形态特征为表面深裂、粗糙且坚硬，有落皮层，周皮与形成层平行。
结论
本研究中观察到的各种生药学特征有助于全缘叶波罗蜜的鉴定和标准化。
