Revaluing agri-food waste to offer consumers bioactive compounds for a healthy diet is an important issue. In the present work, the antioxidant capacity (AC), total phenolic content (TPC) and phenolic compounds of pulp and bagasse of four Peruvian berries with UHPLC-DAD was determined. Elderberry ( Kunth) bagasse had a greater amount of TPC (4.87 ± 0.02 mg GAE/100 gfw) and AC (7.66 ± 0.04 and 7.51 ± 0.24 μmol TE/gfw in DPPH and ABTS, respectively) than the bagasse of the other berries, with a strong positive correlation between TPC and AC. Blueberry ( Kunth) bagasse contains the highest amount of gallic acid (103.26 ± 1.59 μg/gfw), chlorogenic acid (1276.55 ± 1.86 μg/gfw), caffeic acid (144.46 ± 1.78 μg/gfw), epicatechin (1113.88 ± 1.82 μg/gfw) and p-coumaric acid (77.82 ± 1.92 μg/gfw). Elderberry ( Kunth) bagasse contains the highest amount of catechin (153.32 ± 0.79 μg/gfw). No significant differences were found in the content of chlorogenic acid and epicatechin of blackberry ( Poir). It was shown that the wastes of the four Amazonian berries have higher values of bioactive properties than their pulp, being the elderberry bagasse the one with the best properties.
重新评估农业食品废弃物以向消费者提供具有生物活性化合物的健康饮食是一个重要问题。在本研究中，采用超高效液相色谱-二极管阵列检测器（UHPLC-DAD）测定了四种秘鲁浆果的果肉和蔗渣的抗氧化能力（AC）、总酚含量（TPC）及酚类化合物。接骨木浆果（Kunth）蔗渣的TPC含量（4.87±0.02毫克没食子酸当量/100克鲜重）和AC（在DPPH和ABTS中分别为7.66±0.04和7.51±0.24微摩尔TE/克鲜重）高于其他浆果的蔗渣，TPC与AC之间存在强正相关。蓝莓（Kunth）蔗渣中没食子酸（103.26±1.59微克/克鲜重）、绿原酸（1276.55±1.86微克/克鲜重）、咖啡酸（144.46±1.78微克/克鲜重）、表儿茶素（1113.88±1.82微克/克鲜重）和对香豆酸（77.82±1.92微克/克鲜重）含量最高。接骨木浆果（Kunth）蔗渣中儿茶素含量最高（153.32±0.79微克/克鲜重）。黑莓（Poir）的绿原酸和表儿茶素含量未发现显著差异。结果表明，这四种亚马逊浆果的废弃物比其果肉具有更高的生物活性特性值，接骨木浆果蔗渣的特性最佳。
