Chemical composition of the edible leaves of Pterocarpus mildbraedii.
Proximate composition, mineral element content, amino acid profile and the levels of some antinutrients in the edible leaves of Pterocarpus mildhraedii were determined. Moisture content was assayed as 85.12 percent (wet weight). Protein, fat, ash and fibre contents of the leaf (percent dry weight) were 25.84, 5.23, 6.44 and 7.56 respectively. Mineral element analysis showed high levels of calcium, potassium, magnesium, iron, copper, manganese and zinc. However, the level of sodium in the vegetable was low. Amino acid profile indicated that the leaf is rich in essential amino acids. The antinutrient levels of hydrogen cyanide and oxalate were low. The paper suggests the need to meet nutrient requirements through an increased use of this cheap but less popular food item with good nutritive potential.
