Ambelania acida is native to the Amazon region, with few published studies of its fruits. We examined the proximate composition of its fruits, including minerals, fatty acids, volatile organic compounds (VOCs), as well as its antioxidant capacity. The protein contents (2.61%) of the pulp and seeds (13.6%) were higher than observed in other taxa of the family or in other tropical fruits. Peel and pulp showed high contents of potassium, calcium, and magnesium, and the potassium content in the pulp was 1125 mg/100 g. The peel had higher contents of total phenolics, tannins, and ortho-diphenols than the pulp, as well as better antioxidant activity as evidenced by 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), 1,1-diphenyl-2-picrylhydrazyl (DPPH), Ferric Reducing Antioxidant Power (FRAP), and Fe chelating activity assays. GC-MS analyses identified 42 VOCs in the peel and pulp, with more than 90% being classified as terpenes. Eleven types of fatty acids were identified in the lipid fractions of the peel, pulp, and seeds. Linoleic acid, an essential fatty acid for humans, was the principal fatty acid in the edible portion of the fruit, therefore, evidencing its nutritionally significant profile for the fruits when considering the relationship among polyunsaturated, saturated, and monounsaturated fatty acids. The information gathered here indicates that this native fruit is a healthy food source and its cultivation and consumption should be stimulated.
嗜酸安贝利亚原产于亚马逊地区，关于其果实的研究较少。我们研究了其果实的近似组成，包括矿物质、脂肪酸、挥发性有机化合物（VOC）以及抗氧化能力。果肉和种子中的蛋白质含量（2.61%）高于该科的其他分类群或其他热带水果。果皮和果肉含有丰富的钾、钙和镁，果肉中的钾含量为 1125mg/100g。果皮中的总酚、单宁和邻二苯酚含量高于果肉，并且具有更好的抗氧化活性，这一点可以通过 2,2'-偶氮双（3-乙基苯并噻唑啉-6-磺酸）（ABTS）、1,1-二苯基-2-苦基肼（DPPH）、铁还原抗氧化能力（FRAP）和 Fe 螯合活性测定来证明。GC-MS 分析在果皮和果肉中鉴定出 42 种 VOC，其中超过 90%被归类为萜类化合物。在果皮、果肉和种子的脂质部分中鉴定出 11 种脂肪酸。亚油酸是人体必需的脂肪酸，是果实可食用部分的主要脂肪酸，因此，从多不饱和、饱和和单不饱和脂肪酸的关系来看，该果实具有重要的营养特征。这里收集的信息表明，这种本地水果是一种健康的食物来源，应该刺激其种植和消费。
