Phenolic compounds have attracted a lot of attention due to their benefits to human health. Jabuticaba () fruit has been described as an excellent source of these compounds, while Jabuticaba leaf, considered as plant residue, has shown functional effects. The present study aimed to characterize the phenolic profile in two different leaves extracts (hydroalcoholic ethanol and butanol) of by UPLC-ESI-QTOF-MS. A total of 40 phenolic compounds were tentatively identified. Jabuticaba leaf extracts presented a rich and diversified composition of phenolic compounds, especially flavonoids, being ellagic acid, quercetin 3-O-glucoside, gallocatechin, and epigallocatechin the most abundant in butanol extracts. Very distinct phenolic profiles were obtained depending on the the solvent indicating that specific preparations can be obtained from the jabuticaba leaf depending on the desired application. This work emphasized the potential of this residue vegetable to be used as a functional ingredient.
由于其对人类健康的益处，酚类化合物引起了广泛关注。嘉宝果的果实被描述为这些化合物的极好来源，而被认为是植物残余物的嘉宝果叶则表现出了功能性作用。本研究旨在通过 UPLC-ESI-QTOF-MS 对嘉宝果的两种不同叶提取物（水醇乙醇和正丁醇）进行酚类成分分析。共鉴定出 40 种酚类化合物。嘉宝果叶提取物中含有丰富多样的酚类化合物，尤其是类黄酮，其中以鞣花酸、槲皮素 3-O-葡萄糖苷、没食子儿茶素和表没食子儿茶素没食子酸酯含量最为丰富。根据溶剂的不同，得到了非常不同的酚类图谱，这表明可以根据所需的应用从嘉宝果叶中获得特定的提取物。这项工作强调了这种蔬菜残余物作为功能性成分的潜在用途。
