Comparison of Nutritional Composition, Antinutritional Factors and Antioxidant Potentials of Orange-Fleshed Sweet Potato Leaves

There is increasing consumer demand for functional and bioactive ingredients in foods to promote human health and ensure nutrition security in the developing regions of the world. Locally produced staples can be improved with specific micronutrients using conventional breeding methods. Orange fleshed sweet potatoes are a new variety of sweet potatoes; bred to produce nutrient dense products which can curb micronutrient deficiencies.In order to address vitamin A, macronutrient, and micronutrient deficits in sub-Saharan Africa and Asia, OFSP (Orange fleshed sweet potato) leaves can be used. In this study, the nutritional composition and antinutritional composition, and in vitro antioxidant potentials of orange-fleshed sweet potato (OFSP) leaves compared to fluted pumpkin (Telfairia occidentalis) leaves were investigated. Fresh OFSP and pumpkin leaves were washed, dried, pulverized into powder and used for subsequent analysis. The OFSP contained higher (p ≤ 0.05) contents of protein, ash, dietary fiber, amino acids, minerals, β -carotene, vitamins C, D and E, lutein, total anthocyanin, phytochemicals, and antioxidant activities than fluted pumpkin leaves. The use of OFSP leaves could aid the reduction of micronutrient deficiencies and hidden hunger in poor urban and rural communities in developing countries including Nigeria. The high potassium content of OFSP leaves is advantageous to reduce hypertension and alleviate the scourge of cardiovascular diseases.
