ABSTRACT
The aim of this research Study is to analyse qualitatively and quantitatively the Aloe barbadensis for Proximate, Anti-Nutrient and Phytochemical composition. The Proximate, Anti-Nutrient composition and Phytochemical screening of Aloe barbadensis were determined. The Proximate composition involves the Moisture content, Crude protein, Crude fibre, Crude Fat, Ash content and Carbohydrate. The Anti-Nutrients involved Oxalate, Tannins and Phytate while the Phytochemicals determined were the Saponins, Phenols, Alkaloids and Flavonoids. Aloe barbadensis was found to be rich in Carbohydrate (73.07%), so it can be used as a good source of Carborhydrate. The Protein and Fat content were found to be relatively low, (4.73 and 0.27%) respectively. But Aloe barbadensis can still be used as a source of Protein and Fat. Qualitatively, Tannin, Oxalate and Phytate were found in trace amount. Tannin, Phytate and Oxalate contents were 0.155 g/100 g, 0.683 g/100 g, and 0.524 g/100 g respectively. This could affect the availability of Minerals in Aloe barbadensis. It was also discovered that Phytochemicals are present in quantities of 0.232 g/100g, 5.651 g/100 g, 2.471 g/100 g and 3.246 g/100 g for Phenols, Saponins, Alkaloids and Flavonoids respectively. This is an indication of Cosmetic and medicinal Value of Aloe barbadensis. The Sample was also found to be a rich source of minerals. Sodium and Potassium content (5280 and 10670 PPM) respectively indicates the tendency of Aloe barbadensis to be able to regulate or control the osmotic balance of the body fluid as well as body pH. Aloe barbadensis is also found to be rich in Phosphorus (6657 PPM), which is essential for bone formation. Lead occur in traces. Magnesium (325.8 PPM) is also present, which could help to lower the blood pressure. The overall data suggest that Aloe barbadensis has some Nutritional and Medicinal Properties.
