The present work had the objective of producing liqueurs from mango peels (varieties "Haden" and "Tommy Atkins") by processes of alcoholic maceration and maceration with pectinase, as well as to evaluate bioactive compounds by reversed-phase high-performance liquid chromatography coupled to diode array detection and fluorescence-detection (RP-HPLC/DAD/FD) and in vitro antioxidant activity (AOX), for by-product potential reuse. Alcoholic maceration in wine ethanol (65% /) produced liqueurs with higher phytochemical and AOX content. Maceration with pectinase resulted in liqueurs with higher quercetin-3--glucopyranoside content. In relation to mango varieties, Haden liqueurs presented higher bioactive content than Tommy Atkins liqueurs. The liqueurs presented high antioxidant activity. The main bioactive compounds found were flavanols (epicatechin-gallate, epigallocatechin-gallate), flavonols (quercetin-3--glucopyranoside and rutin), and phenolic acids (gallic acid, -coumaric acid, and syringic acid). The present study showed that the production of liqueur enabled the recovering of an important part of the bioactive content of mango peels, suggesting an alternative for the recovery of antioxidant substances from this by-product.
本研究旨在通过酒精浸渍和果胶酶浸渍工艺，用芒果皮（“哈登”和“汤米·阿特金斯”品种）生产利口酒，并通过反相高效液相色谱-二极管阵列检测和荧光检测（RP-HPLC/DAD/FD）以及体外抗氧化活性（AOX）评估生物活性化合物，以实现副产品的潜在再利用。用葡萄酒乙醇（65% /）进行酒精浸渍生产的利口酒具有更高的植物化学成分和AOX含量。用果胶酶浸渍得到的利口酒中槲皮素-3-葡萄糖苷含量更高。就芒果品种而言，哈登利口酒的生物活性含量高于汤米·阿特金斯利口酒。这些利口酒具有较高的抗氧化活性。发现的主要生物活性化合物有黄烷醇（表儿茶素-没食子酸酯、表没食子儿茶素-没食子酸酯）、黄酮醇（槲皮素-3-葡萄糖苷和芦丁）以及酚酸（没食子酸、对香豆酸和丁香酸）。本研究表明，利口酒的生产能够回收芒果皮中重要部分的生物活性成分，为从该副产品中回收抗氧化物质提供了一种替代方法。
