ABSTRACT
Natural products have provided important therapeutic use in several areas of medicine. The Leaves of Lagerstroemia speciosa were reported to possess good Anti-Diabetic activity. This study deals with microscopical analysis, different extraction process, preliminary phytochemical analysis and physicochemical parameters like Ash value, Loss on drying, Extractive value, which could be used to prepare a monograph for the proper identification of the plant. Microscopical analysis showed the leaf is dorsiventral, hypostomatic, xeromorphic and thick-coriaceous. It has prominent midrib and lateral view. To identify the major compounds, the two extraction process, Soxhlet and decoction extraction procedures were adopted. Based on the literature review, four different solvents like Aqueous, 80%Ethanol, Methanol, Ethyl acetate were used for extractions. These Extracts were subjected to preliminary phytochemical analysis which reveals the presence of Tannins and Terpenoids. Powdered leaves were also subjected to fluorescence analysis using different chemicals, among them aqueous sodium hydroxide showed good fluorescence green color. Physicochemical parameters results were compared with the standard value and their results are reported.
