A pharmacognostical Study of Salix Tetraspema Roxb Family Salicaceae Cultivated in Egypt

A Pharmacognostical Study of Salix tetrasperma Roxb. Family Salicaceae Cultivated In EgyptSalix is a widespread temperate genus of the family Salicaceae which is characterized by the presence of many biological active compounds such as: sterols, terpenes, flavonoids, simple phenolics, tannins and lignans.So, this thesis comprises a phamacognostical study of Salix tetrasperma Roxb. belonging to family Salicaceae to perform:1. Botanical study of its different organs to facilitate the identificationof the plant in both entire and powdered forms.2. Isolation and characterization of its chemical constituents.3. Biological study of the plant extracts.Thus, the present study was performed in three parts included: botanical study, phytochemical study and biological activities.Part IMacro- and Micromorphology of Salix tetrasperma Roxb.
