Chemical Content investigation and Anatomy Characters of some Asteraceae family wild plants grown in western of Iraq

Abstract

Asteraceae family (Compositae)is one of the large plant families, widely spread, and this study targeted a small part of it, the results showed that the species were rich in these compounds. A spectrophotometric study was also carried out with the Uv device to measure the highest lambda max for each plant, and a difference appeared in the values of the curves, which indicates the diversity of chemical compounds in their extracts. The study included also the distinctive anatomical characteristics and quantitative characteristics of the stems and roots, and included the dimensions of the epidermal layer, the cortex, the vascular cylinder and its components, the pith rays, and the pith through the cross-sections of four Species belonging to the family Leontodon laciniatus, Lactuca serriole Chrysophthalmum montanum, Onopordum canum, wild. These sections gave a clear and new anatomical fingerprint for each type of phenotypic and genetic fingerprints previously used to isolate taxonomic plant species. The sections were photographed microscopically. A general chemical detection of secondary metabolites of the crude ethanolic extract was performed for each of the four plants separately. Alkaloids, tannins, and glycosides
