Abstract: Pomegranate (Punica granatum) has been used for thousands of years to cure a wide range of diseases like diabetes, cancer, osteoarthritis, cardiovascular diseases and other myriad ailments across different cultures and civilizations. This is because pomegranates have the potential to thin the blood, increases blood flow to the heart, reduce blood pressure, plaque in the arteries, bad cholesterol parallel increasing good cholesterol. For experiments, proximate composition (moisture, ash, protein, fat, crude fiber, carbohydrate and vitamin C) were done by using Association of Analytical Communities (AOAC) standard methods. Mineral compositions (Na, Ca, Mg, K, P, Fe and Zn) were determined by atomic absorption spectrophotometry. UV spectrophotometer was used to determine phosphorous. Solvent free extract filtrate was used with various alkaloidal reagents to determine phytoconstituents. The result of the analysis shows that the peel, seed and whole fruit powder contains moisture content, ash, protein, crude fiber and fat. It also contains sodium, calcium, magnesium, potassium, phosphorus and iron. The three different extracts from peel, seed and whole fruit powder were found to contain alkaloids, flavonoids, phenolic compounds, glycosides, saponins, carbohydrates and protein. All of these findings implied that minerals and phytochemicals and vitamin C from pomegranate peels, seeds and whole fruit might be potential resources for the development of antioxidant function dietary foods and are useful in preventive healthcare.
