The aim of the current study was to assess and compare the microscopic and pharmacognostic features of the selected parts of Astragalus scorpiurus Bunge. It is an annual and prostrate herb. Anatomy of leaves, stem, and root depicted a typical dicot structure. It will provide information regarding standardization and authentication. The powder drug study (Light Microscopy and Scanning Electron Microscopy) revealed the presence of xylem and phloem vessels, epidermal fragments, cortical cells, fibers, parenchyma tissue, calcium oxalate crystals, nonglandular trichomes, anomocytic stomata, and so on. It will be helpful in identification and quality control. Pollen and seeds micro-morphological features were observed through LM and SEM. These will play a vital role in the taxonomical identification of taxa and provide satisfactory information for taxonomists. Fluorescence analysis revealed different colors under visible and UV light. Extractive values were determined. Powder of the plant parts revealed high extraction in methanol followed by ethanol. Elemental and nutritional profiling were evaluated during two phenological periods that is, vegetative and postflowering period. There were significant phenological variations in mineral and nutritional status of the herb. These parameters are crucial for drug prescription and drug designing. These also provided information regarding nutraceutical and therapeutic value of this herb.

黄芪的显微和生药标准化
本研究的目的是评估和比较黄芪选定部位的微观和生药特征。邦吉。它是一年生和匍匐的草本植物。叶、茎和根的解剖描述了典型的双子叶植物结构。它将提供有关标准化和认证的信息。粉末药物研究（光学显微镜和扫描电子显微镜）揭示了木质部和韧皮部血管、表皮碎片、皮质细胞、纤维、薄壁组织、草酸钙晶体、非腺毛状体、单核细胞气孔等的存在。这将有助于识别和质量控制。通过LM和SEM观察花粉和种子的微形态特征。这些将在分类群的分类鉴定中发挥至关重要的作用，并为分类学家提供满意的信息。荧光分析揭示了在可见光和紫外光下的不同颜色。测定提取值。植物部分的粉末显示出在甲醇和乙醇中的高提取率。在两个物候期，即营养期和花后期，对元素和营养分析进行了评估。该药草的矿物质和营养状况存在显着的物候变化。这些参数对于药物处方和药物设计至关重要。这些还提供了有关这种草药的营养和治疗价值的信息。
