Chemical and Biological Investigation of Certain Species Belonging to Genus Cassia Family (Caesalpiniaceae)

Abstract

Family Leguminosae is one of the largest families of the flowering plants. It comprises about 650 genera and 18000 species. Family Leguminosae is divided into three sub-families: Papilionoideae, Caesalpinioideae and Mimosoideae. These sub-families are now treated as independent families due to their large size and named Papilionaceae, Caesalpiniaceae and Mimosaceae. Cassia genus is a large tropical genus with about 600 species of herbs, shrubs and trees and belongs to Caesalpiniaceae. The main objective of this study is the phytochemical study of the aqueous alcoholic extract of Cassia glauca leaves, fractionation and preparation of silver nanoparticles (AgNPs) of different fractions then biological investigation of the total extract, silver nano particles fractions and isolated compounds. This study was divided into four main chapters: Chapter (1): A preliminary phytochemical screening of Cassia glauca leaves followed by an in-depth phytochemical study of its aqueous alcoholic leaves extract. Further chromatographic separation will be carried out to characterize and isolate the relevant compounds. Chapter (2): Green Synthesis of Silver Nanoparticles from Cassia glauca leaves
