Anatomical structure of the reed flower Echinacea purpurea (L.) Moench

Abstract

The article presents the results of scientific research on the determination of the anatomical structure of the
reed flower Echinacea purpurea(L.) Moench introduced in South Kazakhstan. To prepare the
micropreparation, the lingual flowers of the plant were taken; they are purple, 2.5–6 cm long, inner 4mm
long. The films of the flower are lanceolate awl-shaped, 1–1.5 cm long, 1–1.5 mm wide, with a straight
prickly tip. Previously, the anatomical structure of the leaf, stem and root of Echinacea purpurea were
studied. The purpose of the study is to examine theanatomical structure of the lingual flower of E. Purpurea
to identify diagnostic signs characteristic of thistype, necessary for the development of effective and low-toxic domestic drugs. Information about the anatomical features of the generative organs of the studied
species is given for a complete diagnosis of medicinal plant raw materials, which can be seen in
microphotographs taken by a computer microphotometer. The following anatomical features necessary for the
identification of raw materials have been identified, i.e., signs by which the studied object can be
distinguished from similar parts of another plant: the outline of epidermal cells on the adaxial structure is
rectilinear, the projection is polygonal, on the abaxial — weakly branched; stomata are not submerged, anomocytic type; the structure of the mesophyll of the lingual flower is aerenchyma with well-defined intercellular lacunae; the presence of lamellar collenchyma under the abaxial epidermis; conducting bundles are closed collateral; the location of schizogenic secretory receptacles above conducting bundles.
