This study aimed to characterize jabuticaba (Myrciaria cauliflora), guabiju (Myrcianthes pungens), and jambolan (Syzygium cumini) in relation to its individual phenolic compounds (LC-ESI-MS/MS), antioxidant capacity, total monomeric anthocyanin, sugars, and minerals during ripening (intermediate and ripe stages). In the three studied fruits, 22 phenolic compounds were quantified, especially phenolic acids and flavonoids, which presented a higher concentration in the intermediate ripening stage. In contrast, the total monomeric anthocyanin, fructose, glucose, Ca, Na values were higher in the ripe stage. In addition, all studied fruits showed expressive antioxidant capacity in both ripening stages: 2569.28 to 5066.35mg AAE 100g DW for DPPH; 13777.52 to 26667.45µmol Fe 100g DW for FRAP; and 957.72 to 2061.35mg GAE 100g DW for Folin-Ciocalteu reducing capacity. Therefore, our results revealed that these fruits represent a supply of high-value nutrient and bioactive components, especially in the ripe stage.
本研究旨在对巴西番樱桃（Myrciaria cauliflora）、瓜比朱（Myrcianthes pungens）和蒲桃（Syzygium cumini）在成熟过程中（中期和成熟阶段）的单个酚类化合物（LC-ESI-MS/MS）、抗氧化能力、总单体花青素、糖类和矿物质进行表征。在这三种研究的水果中，定量了22种酚类化合物，尤其是酚酸和黄酮类化合物，它们在成熟中期阶段的浓度较高。相比之下，总单体花青素、果糖、葡萄糖、钙、钠的值在成熟阶段较高。此外，所有研究的水果在两个成熟阶段均表现出显著的抗氧化能力：DPPH法为2569.28至5066.35mg AAE/100g DW；FRAP法为13777.52至26667.45µmol Fe/100g DW；福林-西奥尔特法还原能力为957.72至2061.35mg GAE/100g DW。因此，我们的结果表明，这些水果是高价值营养和生物活性成分的来源，尤其是在成熟阶段。
