This study evaluated nutritional values, bioactive constituents and antioxidant activities of the five wild underutilized fruits in the mountains of southwest Saudi Arabia ( (L.) Voigt, Hochst. Ex A.Dc., (L.), Forssk., and Willd.). The moisture content, crude fibers, total protein, total lipids, total hydrolyzable carbohydrate, total soluble sugars, and total free amino acids were analyzed. The results showed varying amounts among fruits of the five study species. In addition, the mineral composition, amino acid content, phenolic compounds, vitamins, and antioxidant activity were assessed. The highest content of total phenolic and total tannins was measured in (20.69 mg/g and 3.84 mg/g) and the lowest in (10.83 mg/g and 1.44 mg/g), respectively. The methanol extract (1 mg/ml) of displayed higher percentage of DPPH radical scavenging activity (87.36%). The methanol extract (1 mg/ml) of exhibited the highest effect of total antioxidant activity and hydrogen peroxide scavenging activity (71.53%). The sufficient nutritional and antioxidant value of these wild fruits provide healthy food source for the local residents, much the same as many cultivated fruits and vegetables.
本研究评估了沙特阿拉伯西南部山区五种未充分利用的野生水果（（L.）沃伊特、霍赫施特. 前A.Dc.、（L.）、福斯克. 和威尔德.）的营养价值、生物活性成分和抗氧化活性。分析了水分含量、粗纤维、总蛋白、总脂质、总可水解碳水化合物、总可溶性糖和总游离氨基酸。结果显示，五个研究物种的果实含量各不相同。此外，还评估了矿物质组成、氨基酸含量、酚类化合物、维生素和抗氧化活性。总酚和总单宁含量最高的分别是（20.69毫克/克和3.84毫克/克），最低的是（10.83毫克/克和1.44毫克/克）。的甲醇提取物（1毫克/毫升）表现出较高的DPPH自由基清除活性百分比（87.36%）。的甲醇提取物（1毫克/毫升）表现出最高的总抗氧化活性和过氧化氢清除活性（71.53%）。这些野生水果充足的营养和抗氧化价值为当地居民提供了健康的食物来源，与许多栽培水果和蔬菜非常相似。
