Extracts of jabuticaba peels show complex chromatographic profiles at 360 nm, with some peaks presenting UV–Vis spectra resembling those of flavonol glycosides and others resembling that of ellagic acid. The presence and tentative identification of these phenolic compounds were comprehensively studied in four species of Brazilian jabuticaba fruit – Plinia trunciflora, variety ‘jabuticaba de cabinho’; P. caulifora, varieties ‘jabuticaba paulista’ and ‘jabuticaba canaã-açu’; P. jaboticaba, variety ‘jabuticaba sabará’; and P. phitrantha, variety ‘jabuticaba branca-vinho’ – using HPLC-DAD-ESI-MSⁿ. Seventeen flavonols derived from quercetin and three from myricetin and eighteen derivatives of ellagic acid and eleven of methyl ellagic acid were detected. Most of them were newly described and mainly occurred in glycosylated and acylglycosylated forms. Some compounds were missing in one variety, such as the absence of methyl ellagic acid derivatives in ‘jabuticaba branca-vinho’, and others only appeared in one variety, thus suggesting potential capacity for varietal differentiation.

Jabuticaba果皮的提取物在360 nm处显示出复杂的色谱图，其中一些峰的UV-Vis光谱类似于黄酮醇苷的峰，而另一些峰则类似于鞣花酸。这些酚类化合物的存在和初步鉴定已在巴西jabuticaba的4种果实中进行了全面研究，即Plinia trunciflora， 'jabuticaba de cabho'变种。P. caulifora，变种“ jabuticaba paulista”和“ jabuticabacanaã-açu”；P. jaboticaba，变种“ jabuticabasabará”；和P. phitrantha，品种'嘉宝果礁岛-的Vinho' -使用HPLC-DAD-ESI-MS ^Ñ。检出了槲皮素中的十七种黄酮醇，杨梅素中的三种黄酮醇以及鞣花酸的十八种衍生物和甲基鞣花酸的十一种。它们中的大多数是新近描述的，并且主要以糖基化和酰基糖基化的形式出现。一种化合物中缺少某些化合物，例如'jabuticaba branca-vinho'中不存在甲基鞣花酸衍生物，而另一些仅出现在一种中，因此表明潜在的品种分化能力。
