ANATOMICAL AND BIOCHEMICAL STUDY OF LACTUCA SERRIOLE L. FROM THE ASTERACEAE SPECIES GROWN IN THE WEST OF IRAQ

Abstract

The present study was aimed to explore the important of Lactuca serriole L. (Synonym : Lactuca scarioala L.), were growth wildly in west of Iraq and used un traditional medicine. When we studied anatomical and Biochemically, the anatomically study description different internal tissues of the plant organs (leaf blades, petioles, stems and roots) and measured the details. These characteristics have include epidermis studies are considered important characters like cell forms which were square and compact with non- divisible bristles. The vascular system of the root, stem, petioles and leaves was of good structure with wide ribs and thick fibers. The chemical characteristics of the plant include a qualitative and quantitative identification of some active components such as alkaloids, glycosides, saponins and tannins has been carried out, Phenols with the highest ratio (7.88%) have been pathogenic tested for some pathogenical bacteria using the minimum inhibitory concentration method. A good inhibition activity was found on Pseudomonas aeruginosa with a rate of 603 mg/ml. This has been compared with some antibiotics, including ciprofloxin and erythromycin.
