Preparation and Evaluation of Mucilage from Fresh Leaves of Psidium guajava

Abstract

The main objective of this research was to determine a practical follow-up to the extraction and isolation of mucilage from Guava leaves and to characterize it in a laboratory. The Dried leaves powder was then grinded to prepare fine powder which was then used for extraction. It was then extracted with various solvents from non polar to polar such as petroleum ether, chloroform, acetone, and alcohol and aqueous successfully. The various extracts of the powdered leaves of Psidium guajava subjected to chemical tests for identification of its active constituents. The results of the present investigation revealed that the prepared mucilage characterized as mucilage as compared with the available mucilages. It shows best results in evaluation by shear stress, tensile strength, shear strength, falling sphere, swelling factor, viscosity, stability studies.
