Microscopic study of the herbs a wormwood annual

Artemisia annua L. (Artemisia annua L.) is a herbaceous annual plant, used in folk medicine of China for more than two thousand years. In the 70s of the 20th century, the sesquiterpene lactone artemisinin was isolated from the aerial part of this species - the most effective among medicinal products for the treatment of malaria. The aim of the study was to study the microscopic characteristics of a given plant and to establish diagnostic features for a particular type of raw material, namely, herb wormwood, one-year old. The study was conducted using library databases (eLibrary) and the results of their own research. Studied medicinal raw materials collected in the vicinity of Pyatigorsk. Fresh raw materials were used for the study. A detailed microscopic analysis of the leaves, flowers and stems of Artemisia was carried out. The shape and sinuosity of the anticlinal walls of wormwood annual leaves have been studied, the type of stomata has been established, and such trichomes as essential oil glands, T-shaped hairs and their remains have been discovered and examined, the pollen flower covering the flower surface is established for flowers. The structure of the stalk of a wormwood is studied annually. Diagnostic signs of herbs of annual wormwood are Tshaped hairs, as well as two-rowed 4-tiered essential oil glands located on the epidermis of the leaf and stem, as well as essential oil glands consisting of two excretory cells located in the upper tier of a two-row 4- tier structure. The glands are localized on the leaf epidermis, flowers and wrapping.
