Dodonaea is a predominantly Australian genus of the family Sapindaceae which is characterized by the presence of many biological active compounds such as: sterols, terpenes, saponins, flavonoids, coumarins and coumarinolignans. So, this thesis comprises a phamacognostical study of a plant from this family and belongs to genus Dodonaea which is cultivated in Egypt, namely Dodonaea viscosa to perform:1. Botanical study of its different organs to facilitate theidentification of the plant in both entire and powderedforms.2. Isolation and characterization of its chemical constituents.3. Biological study of the plant extracts.I- Macro- and Micromorphological study of different organs
