MACROSCOPIC AND MICROSCOPIC ANALYSIS OF BURNET HERBAL RAW MATERIAL

Abstract

The article presents the results of the study of morphological and anatomical features of burnet raw materials with the use of macroscopic and microscopic analysis. The study revealed characteristic external signs of burnet, identifying raw material: for the herb it is a description of stems, leaves, flowers and blossoms, their color and smell; the morphological features of the roots and rhizomes include the nature of bending and coloring of the outer cork. Investigation of microscopic features of burnet raw material determined diagnostically significant signs that allow to set the indicators of authenticity. Description of burnet pays attention to the sinuous epidermal cells of leaves with clearly visible bulges, amphistomatic leaf type, stomata of irregular-celled type; presence of simple, capitate trichomes, clusters of calcium oxalate, a container with yellow contents; the polygonal cells of the epidermis of the flower with simple hairs, clusters, stomata of anomocytic type, characteristic of the pollen grains. Rhizomes of burnet is characterized by a well-pronounced core with large parenchymal cells, cork, primary bark, continuous cambial ring, powerful radial rays. Roots of burnet have a secondary structure with a pronounced cork, primary bark, central cylinder and characteristic microdiagnostic elements.
