ABSTRACT:Matricaria pubscens (Asteraceae), with wide distribution area in southern Algeria, is a drug traditionally used in the treatment of certain diseases such as dehydration, cough and sore. The aim of this study was to determine the anatomical features of the root stem and leaves of medicinal species of M. pubscens sections. As a result of the study, it was discovered that in the root the vessels arranged in short multiple radial; the fibers are thin-walled thick, Vascular bundles are separated by large unlignifid rays.Most vessels in the central part are plugged with dark-staining substances. The anatomical structure of the leaves is isobilateral mesophyll and palisade parenchyma nearly two epidermises and spongy parenchyma in the middle, the leaf was bifaceous. The surface of the epidermis is covered with glandular hairs, the stomata were diastatic. The extract of aerial part of M. pubscens has significant amounts of Phenols, Flavonoids and Steroids, however tannins are present an average amount; the Alcaloids are present in lowest amount.
