Microscopic examination of the Cephalaria gigantea (Ledeb.) Bobrov

Aim – to study the anatomical structure of the aerial part of the herb Cephalaria gigantea. Material and methods. The study method was the light microscopy in transmitted and reflected light on Motic DM-39C-N9GO-A and DM-1802-Digital Microscopy with magnification ratios: x40, x100, x400, x1000. Results. The anatomical analysis of the stems and leaves of the Cephalaria gigantea revealed the structural features of its main aerial vegetative organs. The most significant findings were: glandular trichomes with a two-row head; covering simple unicellular hairs with a raised rosette of cells at the base, as well as their warty cuticle; submersion of anomocytic stomatal apparatus on stems relative to the epidermis; amphistomatic type of dorsoventral leaf; wavy tortuosity of the cell walls of the epidermis on the underside of the leaf blade. Conclusion. The data obtained will allow us to develop the section “Microscopic characteristics” in the draft pharmacopoeial monograph for a new type of medicinal plant Cephalaria gigantea.
