The aim of this work was to achieve a preliminary characterization of the profile of the phenolic fraction of virgin olive oils (VOOs) from Maipú (Mendoza, Argentina). Thus, 25 commercial VOO samples from Arauco, Arbequina, Picual, Frantoio, Changlot, Empeltre, Nevadillo, Manzanilla, and Coratina (both monovarietals and blends) were analyzed using LC-ESI-QTOF MS and LC-ESI-IT MS for identification and quantification purposes, respectively. A rapid LC method (15 min) accomplished quantitative information about a total of 40 phenolic compounds, including secoiridoid derivatives, which have not been evaluated before in samples coming from the subregion so-called Maipú (Mendoza province, Argentina). The results make evident that olive oils coming from Mendoza can be considered as important sources of phenolic bioactive compounds, exhibiting similar phenolic compound levels to those shown by oils from other typical world production regions. Moreover, some distinctive features of the Arauco variety (Argentinean autochthonous variety) were pointed out; indeed, a correlation between flavonoids content and botanical variety was established herewith.
这项工作的目的是对来自阿根廷门多萨省迈普的初榨橄榄油（VOOs）酚类成分概况进行初步表征。因此，使用LC-ESI-QTOF MS和LC-ESI-IT MS分别对25个来自阿劳科、阿贝基纳、皮夸尔、佛朗托伊奥、尚洛、恩佩尔特雷、内瓦迪约、曼萨尼亚和科拉蒂纳（包括单一品种和混合品种）的商业VOO样品进行分析，以进行鉴定和定量。一种快速液相色谱方法（15分钟）获得了总共40种酚类化合物的定量信息，其中包括裂环烯醚萜衍生物，此前在来自所谓迈普（阿根廷门多萨省）次区域的样品中尚未对其进行评估。结果表明，来自门多萨的橄榄油可被视为酚类生物活性化合物的重要来源，其酚类化合物水平与世界其他典型产区的橄榄油相似。此外，还指出了阿劳科品种（阿根廷本土品种）的一些独特特征；确实，据此建立了黄酮类化合物含量与植物品种之间的相关性。
