Abstract: Background: Leaves of Phragmanthera capitata (Sprengel) Balle growing on rubber trees were evaluated in order to determine its nutritional, anti-nutritional and mineral compositions. Materials and Methods: Proximate and anti-nutrient analyses were performed using standard analytical methods while mineral contents were determined using Inductively Coupled Plasma-Optical Emission Spectrometer (ICP-OES). Result: The result of the proximate analysis showed that carbohydrate was more with a composition of 57.73±0.33 g/100 g. Protein, fat and fibre compositions were 12.50±0.50, 3.34±0.18 and 11.66±0.54 g/100 g. The total energy composition was 310.97±2.30 kcal/100 g. The mineral composition revealed that the leaves of the plant were very rich in basic minerals with high potassium level of 1047.83±34 mg/100 g. Calcium (6.22.58±0.01 mg/100 g), magnesium (361.15±0.01 mg/100 g) and phosphorous (115.40±0.01 mg/100 g) were also present in appreciable amount. The anti-nutrients evaluated had appreciable amounts in phytate (0.15±0.23%), oxalate (2.99±0.61%), saponin (3.46±0.01%) and alkaloid (4.20±0.11%). Conclusion: The study revealed that Phragmanthera capitata could serve as a source of essential nutrients which can go a long way in ameliorating most nutritional challenges and may contribute remarkably to the amount of nutrients in human.
