STUDY ON EXTRACTION, ISOLATION AND PHYSICO-CHEMICAL PROPERTIES OF PSIDIUM GUAJAVA

Abstract

The guava (Psidiumguajava) belongs to family Myrtaceae and is one of the most gregarious of fruit trees. Most of the studieshave been conducted on the phytochemical, biological, and pharmacological of this plant and its parts. However, a very limited number of studies was reported on the physic-chemical properties of guava leaves extracts. The physical properties such as – pH, Solubility, Conductivity, Density and Viscosity, and Optical rotation, were examined and moisture and ash percentage also determined and all the mineral elements (calcium, magnesium, sodium and potassium) were also determined.The results had shown the greatest diversity in all the physical properties. The highest values were recorded with the sample C in case of all the physical parameters, except pH. The results of chemical properties was indicated of various samples contains the cations that is calcium, magnesium, potassium and sodium. The various aqueous extracts were subjected to TLC examination.
