Abstract
Medicinal plants constitute an effective source of traditional and modern medicines. The plant is a biosynthetic laboratory, not only for chemical compounds but also a multitude of the compounds. The present research work was confined to study the macro, microscopic features and analysis of powdered drug of Acacia modesta Wall., Acacia nilotica (L.) Delile, Berberis lycium Royle and Zanthoxylum alatum D. C. Prod. These studies were carried out in Botany laboratory of University of Arid Agriculture, Rawalpindi during 2004. These species are used as miswak (tooth brush) by local people of Pakistan in different areas. Anatomical features such as, fibres, parenchyma cells, vessels and pith were identified during microscopic studies. Powdered miswak of Acacia modesta Wall., Berberis lycium Royle and Zanthoxylum alatum D. C. Prod. were soluble in sulphuric acid only while insoluble in other solvents i.e., hydrochloric acid, acetic acid, benzene and water. Powdered miswak of Acacia nilotica was insoluble in these solvents. Powdered drug of these species did not retain their original colour in cold and hot tests and on dry filter paper, when mixed in various solvents.
