The aim of this work was to determine the nutritional value and antioxidant potential of the pulp and seeds of the fruit of grown and consumed in the Eastern Region of Cameroon. The physicochemical and nutritional analyses of the pulp and seeds showed that the water content ranged from 89.33 to 95.05 % of the fresh matter, the ash from 2.55 to 2.45 % of the dry matter, the pH from 4.50 to 6.10 and the total titratable activity from 76.15 to 9.92 meq/100 g of dry matter. As for the mineral salts, the maximum contents of Ca, Na, Fe, Mg, Zn, K, and Cu were found in the different samples. Regarding the macronutrient composition, we obtained 42.40 and 39.65 % of carbohydrates, 20.96 and 41.61 % of proteins, 6 and 7.06 % of lipids, and 16.13 and 4.27 % of fibers for the pulp and seeds, respectively. The hydroethanolic extract is the best-interacting reagent on the mesocarp and endocarp of , presenting respectively the highest content of total phenolics (36.27 and 30.26 mg EqAG/g extract) and flavonoids (13.48 and 8.1 mg EqCAT/g extract). The best capacity to scavenge the DPPH radical, the best capacity to inhibit the hydroxyl radical and the best-reducing power of ferrous ions were also observed in the hydroethanolic extract of each sample (pulp and seeds) with an efficient concentration 50 of 83.17 and 6760 μg/mL respectively. The fruit of could improve the nutritional status of Eastern Cameroonians based on the results obtained.
这项工作的目的是确定在喀麦隆东部地区种植和食用的该种水果的果肉和种子的营养价值及抗氧化潜力。果肉和种子的理化及营养分析表明，水分含量占鲜重的89.33%至95.05%，灰分占干重的2.55%至2.45%，pH值为4.50至6.10，总可滴定活性为76.15至9.92 meq/100 g干物质。至于矿物盐，在不同样品中发现了钙、钠、铁、镁、锌、钾和铜的最高含量。关于大量营养素组成，果肉和种子的碳水化合物含量分别为42.40%和39.65%，蛋白质含量分别为20.96%和41.61%，脂质含量分别为6%和7.06%，纤维含量分别为16.13%和4.27%。水乙醇提取物是与该种水果中果皮和内果皮相互作用最佳的试剂，其总酚含量（分别为36.27和30.26 mg EqAG/g提取物）和黄酮类化合物含量（分别为13.48和8.1 mg EqCAT/g提取物）最高。在每个样品（果肉和种子）的水乙醇提取物中还观察到清除DPPH自由基的最佳能力、抑制羟基自由基的最佳能力和亚铁离子的最佳还原能力，其有效浓度50分别为83.17和6760 μg/mL。基于所获得的结果，该种水果可以改善喀麦隆东部居民的营养状况。
