In this study, the profile of the bioactive compounds of sapucaia nut (Lecythis pisonis Cambess) and its by-products have been investigated. The phenolic profile by LC-ESI-MS/MS, the total phenolic content, the condensed tannins and the antioxidant activity of the sapucaia nut and shell were determined. 14 phenolic compounds were identified in the sapucaia nut extract, primarily phenolic acids and flavonoids. Catechin, epicatechin, myricetin, ellagic acid and ferulic acid presented significant correlation to the antioxidant activity. The sapucaia shell contained 22 phenolic compounds, 13 of which were quantified. The sapucaia shell extract showed a high content of total phenolic compounds, a high condensed tannins content, and high antioxidant activity. The higher antioxidant activity of the shell can be associated with a higher content of phenolics. Overall, it can be concluded that the sapucaia nut is a raw material rich in phenolic compounds that present high antioxidant activity. The nuts and the cake may be used as a promising raw material for the food industry, while the shells could be an alternative source of natural antioxidants. Further use in the cosmetics and pharmaceutical industry may also be envisaged.

在这项研究中，sapucaia坚果（Lecythis pisonis）的生物活性化合物的概况康布斯（Cambes）及其副产品已被调查。通过LC-ESI-MS / MS测定酚类谱，总酚含量，单宁缩合和乌贼壳和坚果壳的抗氧化活性。在sapucaia坚果提取物中鉴定出14种酚类化合物，主要是酚酸和类黄酮。儿茶素，表儿茶素，杨梅素，鞣花酸和阿魏酸与抗氧化活性显着相关。乌贼壳含有22种酚类化合物，其中13种被定量。乌贼壳提取物显示出高含量的总酚类化合物，高浓缩的单宁含量和高抗氧化活性。壳的较高的抗氧化剂活性可以与较高含量的酚类有关。全面的，可以得出结论，蓝宝石坚果是富含酚类化合物的原料，具有很高的抗氧化活性。坚果和蛋糕可以用作食品工业的有前途的原料，而贝壳可以作为天然抗氧化剂的替代来源。也可以设想在化妆品和制药工业中的进一步使用。
