In this study, pharmacognostic standards of the leaves and fructus of burdock are specified for the first time. &lt;strong&gt;Methods: &lt;/strong&gt;Microscopic analysis was carried out by using the microscope Carl Zeiss. The UV spectrum were measured on an SF-2000 spectrophotometer. &lt;strong&gt;Results:&lt;/strong&gt; Macroscopically, the leaves are heart-shaped, broad-heart-ovate-shaped with a spaced emarginatedserrate or whole edge, with a wide, wedge-shaped, rounded, uneven base, acute apex, green on the outer surface, grayish slightly pubescent on the inner surface. The fructus are obovate or wedge-compressed, slightly curved, the color is brown/black with spots, or variegated with black spots on a gray background. The microscopic examination of the leaves revealed the presence of epidermis, large submerged and non-submerged stomata of the anomocytic type, 2 types of simple unbranched multi-cellular and glandular capitate trichomes; essential oil glands. Microscopic examination of the leaf petiole revealed the presence of 2 types of simple multi-cellular trichomes, epidermis, angular collenchyma, bicollateral bundles, parenchyma. The stomatal index value is 8.28±0.81 per 1cm2. The microscopy of the fructus revealed the presence of elongated cells of the pericarp epidermis; mesocarp; endocarp; endosperm with aleurone grains and drops of fatty oil. The qualitative phytochemical analysis of revealed the presence of polysaccharides, tannins, flavonoids, terpenoids, saponins, phenolic acids. &lt;strong&gt;Conclusion:&lt;/strong&gt; Physical and chemical parameters (moisture, extractive value, ash content) were also specified. These specific data are important for establishing diagnostic indicators for standardization, identification, preparation of new quality standards.&lt;/p&gt;
