Buddleja asiatica commonly known as “Booi” is a large deciduous shrub belongs to family Scrophulariaceae, traditionally used as antipyretic, analgesic, hypotensive, antimicrobial, anti-inflammatory, and antifungal agent recorded from essential oil obtained from leaves. The literature revealed that the plant has been widely used for many other purposes. The said plant has been analyzed through pharmacognostic techniques such as morphological, microscopic, and physio-chemical evaluations to keep the originality of the plant and to avoid adulteration. Morphologically, the plant is evergreen shrub, while organoleptic studies showed that the leaf has glabrous upper surface and tomentose lower surface, with slightly bitter taste and aromatic odor. Anatomically, the leaf showed typical dicot histological differentiation with hypostomatic nature having highest frequency (90%) of actinocytic stomata. The average stomatal number and stomatal index were 336 ± 39.5 and 30.01 ± 2.34, respectively. The palisade cell ratio, vein termination, and vein islet number were 9.2 ± 0.72, 10.2 ± 3.1, and 10.3 ± 3.3, respectively. Various tissue fragments have been observed during powdered drug analysis of the leaf. Preliminary phytochemical screening confirmed the presence of proteins, phenols, alkaloids, saponins, flavonoids, tannins, and glycosides. Fluorescence analysis in ordinary day light and under UV light along with extractive values was also analyzed. The above-mentioned studies that have been reported, for the first time, for the said plant may be significant to establish the pharmacognostic and phytochemical standards of the said species.

Buddleja asiatica叶子的植物化学和生药研究

毛竹俗称“Booi”，是一种大型落叶灌木，属于玄参科，传统上用作解热、镇痛、降压、抗菌、抗炎和抗真菌剂，记录从叶子中提取的精油。文献显示，该植物已被广泛用于许多其他目的。所述植物已通过形态学、显微学和理化评估等生药技术进行分析，以保持植物的独创性并避免掺假。形态学上，该植物为常绿灌木，而感官研究表明，叶片上表面无毛，下表面被绒毛，味微苦，气味芳香。在解剖学上，叶片表现出典型的双子叶植物组织学分化，具有最高频率（90%）的放线细胞气孔。平均气孔数和气孔指数分别为336±39.5和30.01±2.34。栅栏细胞比率、静脉终止和静脉胰岛数量分别为 9.2 ± 0.72、10.2 ± 3.1 和 10.3 ± 3.3。在叶子的粉末药物分析过程中观察到各种组织碎片。初步植物化学筛选证实了蛋白质、酚类、生物碱、皂苷、类黄酮、单宁和苷的存在。还分析了普通日光和紫外光下的荧光分析以及提取值。上述研究首次报道，
