The Amazon rain forest encompasses an extraordinary source of vegetable oils with many applications, especially for food, pharmaceutical and cosmetics industries. In this work, the main composition of fifteen Amazonian oils and butters are investigated via gas chromatography‐mass spectrometry (GC‐MS) and electrospray ionization high resolution mass spectrometry (ESI‐HRMS). Triacylglycerols (TAG) are characterized by their fragmentation spectra and comparison with the LIPID MAPS database, resulting in a detailed compendium of TAG composition of these samples. Over 70 different TAG are putatively annotated per sample and the occurrence of isomers is remarkable, showing that TAG complexity in these samples is considerably higher than ever reported. The TAG composition of the Amazonian samples are also statistically evaluated using principal component analysis (PCA) for comparison to common edible oils such as soybean, corn, coconut, and olive oil. Some tendencies of grouping are observed: butters with medium chain fatty acids (FA); butters with high oleic FA; and oils with high oleic and high linoleic FA contents. This study provided profiles that ensure Amazonian oils and butters authenticity, quality and also aids in understanding their properties and the best applications for each.

通过ESI-HRMS / MS对15种亚马逊油生植物油脂进行全面的三酰基甘油表征，并与普通食用油脂进行比较
亚马逊雨林包含了植物油的非凡来源，其用途广泛，尤其是在食品，制药和化妆品行业。在这项工作中，通过气相色谱-质谱（GC-MS）和电喷雾电离高分辨率质谱（ESI-HRMS）研究了15种亚马逊油脂的主要成分。三酰基甘油（TAG）的特征在于其片段化光谱并与LIPID MAPS数据库进行比较，从而得出了这些样品的TAG组成的详细目录。假定每个样品有70多种不同的TAG注释，并且异构体的出现非常显着，表明这些样品中TAG的复杂性大大高于以往报道的水平。还使用主成分分析（PCA）对亚马逊样品的TAG组成进行统计评估，以与常见食用油（例如大豆，玉米，椰子和橄榄油）进行比较。观察到了一些分组趋势：带有中链脂肪酸（FA）的黄油；高油酸脂肪酸的黄油；以及高油酸和高亚油酸FA含量的油。这项研究提供的资料可确保亚马逊油和油脂的真实性，质量，并有助于理解其特性以及每种油的最佳应用。
