%X The nutrient composition of the five major varieties of groundnut (Arachis hypogaea L.) commonly consumed in the south-western part of Nigeria was investigated. Raw dryshelled samples were analyzed for proximate (moisture, ash, protein, fat, fiber and carbohydrate), ¡®vitamins¡¯ (¦Â-carotene, thiamine, niacin and tocopherol) and minerals (Na, K, Ca, P, Mg, Fe, Mn, Zn, Cu, Se, Co, Al, As, Cd and Pb). Results showed that the groundnuts had 4.12-9.26% moisture, 2.77-3.31% ash, 24.26-26.35% protein, 45.41-48.14% fat, 2.51-2.94% fiber and 15.90-17.75% carbohydrate. All the varieties analyzed showed ¦Â-carotene (63.32-65.35mg/100g), thiamin (0.73-0.98mg/100g), niacin (14.00-16.03mg/100g) and tocopherol (18.62-21.07mg/100g) activities; with boro red having significantly (P < 0.05) higher values in all but ¦Â-carotene. Heavy metals like Co, As, Cd and Pb were not detected in any of the samples and the other minerals vary with K> P> Mg> Ca> Mn> Cu> Na> Zn> Fe> Al> Se in most of the varieties. Boro red also had the highest elemental contents in most of the minerals analyzed. Thus, these groundnuts can be considered useful foodstuffs in minimizing proteinenergy malnutrition (PEM) and micronutrient deficiencies in Nigeria. However, the boro red variety is most recommended. The outcome of this research is a contribution to the food composition table. Se ha investigado la composici¨®n en nutrientes de las cinco principales variedades de man¨ª (Arachis hypogaea L.) de consumo habitual en la parte sur-occidental de Nigeria. A las muestras crudas con c¨¢scara y secas se les analiz¨® su composici¨®n proximal (humedad, ceniza, prote¨ªna, grasa, fibra e hidratos de carbono), vitaminas (¦Â-caroteno, tiamina, niacina y tocoferol) y minerales (Na, K, Ca, P, Mg, Fe, Mn, Zn, Cu, Se, Co, Al, As, Cd y Pb). Los resultados mostraron que el man¨ª ten¨ªa entre 4.12 - 9.26% de humedad, 2.77- 3.31% de cenizas, 24.26 - 26.35% de prote¨ªna, 45.41 - 48.14% de materia grasa, 2.51 - 2.94% de fibra y 15.90 -17.75% de carbohidratos. Todas las variedades analizadas conten¨ªan ¦Â-caroteno (63.32-65.35mg/100g), tiamina (0.73-0.98mg/100g), niacina (14.00-16.03mg/100g) y tocoferoles (18.62-21.07mg/100g), siendo la variedad ¡°Boro rojo¡± la que contiene las cantidades significativamente m¨¢s altas (P < 0.05), de casi todo. Los metales pesados como, Co, As, Cd y Pb no fueron detectados en ninguna de las muestras y los dem¨¢s minerales var¨ªan en la mayor¨ªa de las variedades de la siguiente manera: K> P> Mg> Ca> Mn> Cu> Na> Zn> Fe> Al> Se. La variedad ¡°Boro rojo¡± tambi¨¦n tuvo el mayor contenido elemental en la mayor¨ªa de
