Sweet potatoes in Cameroon: Nutritional profile of leaves and their potential new use in local foods

Abstract: Sweet potato (Ipomoea batatas) leaves especially the beta-carotene fortified varieties are rich in functional macro -and micronutrients such as dietary fibres, antioxidants and other micronutrients deficient in the predominantly starchy staples of most nutritionally vulnerable Africans. In this study, the nutrient content of young leaves and succulent green stems of local and exotic varieties were evaluated using standard analytical procedures. Dry matter content was lowest and highest in young leaves of the e… Show more

“…Therefore, the harvesting interval plays a role in the yield of harvestable leaves. Furthermore, SPL must be harvested along with young apical buds to supplement nutrients in addition to those of leaves [ 17 ]. This is ideal because the apical buds showed the highest level of TPC and a more potent antioxidant activities (AA) than young tender leaves [ 18 ].…”

“…Leafy vegetables have been reported to be significant sources of antioxidants, dietary fibres, vitamins and essential amino acids (Nkongho et al, 2014). Cassava leaves are rich in protein, vitamins (B1, B2, C and carotenoids) and minerals (Calcium, magnesium and potassium) (Dada & Oworu, 2010).…”

“…Las hojas de camote (Ipomoea batatas L.) un subproducto de la agroindustria, ha sido utilizada como planta medicinal para enfermedades de la piel, también las hojas verdes son consumidas como vegetales en ensaladas en China [1], pero principalmente son utilizadas en la alimentación animal especialmente de cerdos ya sean frescas, secas o en ensilados debido a que presentan un considerable contenido de proteínas que van desde 25.5% BS. [2], hasta 37 mg/100 g BS, además que es una fuente de Vit C, β-carotenos, Hierro, Calcio, polifenoles y oxalatos, ya sea que se consuman frescas, secas o cocidas [3], también son ricas en carbohidratos, fibra dietaría, antioxidantes y otros micronutrientes deficientes en alimentos basados en el almidón, y que podrían balancear la dieta [4] [5]. Diferentes estudios revelan que estas hojas son una fuente potencial de compuestos bioactivos [6] ya que poseen polifenoles y actividad antioxidante, como el reporte de un estudio en el que evaluaron extractos metanolicos de estas hojas, los mismos que contenían valores de fenoles totales de entre 2.78 a 5.35 g GAE/100 g BS [7], en otro estudio realizado en hojas de seis variedades de camote se obtuvieron 4.47 a 8.11 g GAE/100 g BS [8] también [1] reportaron 4.48 mg GAE/g BS en extractos con diferentes solventes; así mismo también [9] evaluó la actividad antioxidante en extractos etanolicos con DPPH reportando valores de 38.6 μmol Trolox/gr BH.…”
