The agroindustrial residues have been recognized as important sources of some prominent chemical compounds and hence a viable strategy of obtaining bioactive compounds could be applied to them. The present study was aimed to investigate the presence of bioactive compounds and the antioxidant activity of some Brazilian exotic fruits (achachairu, araçá-boi, bacaba) residues. The antioxidant capacity of fruit residues was evaluated by ORAC, FRAP and ABTS assays. The contents of total phenolic compounds, flavonoids, chlorophylls and carotenoids were determined. The identification and quantification of the phenolic compounds were performed by using the UHPLC-QqQ-MS/MS system. The compounds cinnamic acid, p-coumaric acid, epicatechin and quercetin were identified and quantified in all fruits residues. The residue with the highest antioxidant capacity was bacaba for ORAC (15,285.51±20.38μmolTE/100g) and FRAP (16,916.37±10.01μmolTE/100g) assays, as well as total phenolic compounds in its methanolic extract (1537.45±73.35mgGAE/100g).
农业工业残余物已被认为是一些重要化学化合物的重要来源，因此，获得生物活性化合物的可行策略可以应用于这些残余物。本研究旨在研究一些巴西外来水果（achachairu、araçá-boi、bacaba）残余物中生物活性化合物的存在及其抗氧化活性。通过 ORAC、FRAP 和 ABTS 测定法评估了水果残余物的抗氧化能力。测定了总酚类化合物、类黄酮、叶绿素和类胡萝卜素的含量。采用 UHPLC-QqQ-MS/MS 系统对酚类化合物进行了鉴定和定量。在所研究的所有水果残余物中均鉴定和定量了肉桂酸、对香豆酸、表儿茶素和槲皮素等化合物。bacaba 残留物具有最高的抗氧化能力，其在 ORAC（15,285.51±20.38μmolTE/100g）和 FRAP（16,916.37±10.01μmolTE/100g）测定中，以及在其甲醇提取物中的总酚类化合物（1537.45±73.35mgGAE/100g）中均表现出最高的抗氧化能力。
