A study was conducted on olive oils extracted from olives collected in South West Calabria (Southern Italy) over three harvest years 2010-2011-2012. Three autochthonous cultivars were considered: Cassanese, Ottobratica and Sinopolese and seven allochtonous cultivars: Coratina, Itrana, Leccino, Nocellara Messinese, Nociara, Pendolino and Picholine. Thin Layer Chromatography - Gas Chromatograph (TLC-GC) technique permitted the separation and analysis of the fatty alcohol compounds. A general decline in fatty alcohol content was found during the three months of sampling, most evident in hexacosanol. Pendolino showed the greatest decline. A less evident decrease was measured in the odd chained fatty alcohols, mainly in heptacosanol. Both harvest date and cultivar significantly influenced the fatty alcohol content. This is the first report about the fatty alcohol variation during ripening in olive oil produced in South West Calabria (Southern Italy).
对2010 - 2011 - 2012这三个收获年份从意大利南部卡拉布里亚西南部采集的橄榄中提取的橄榄油进行了一项研究。研究考虑了三个当地品种：卡萨内塞（Cassanese）、奥托布拉蒂卡（Ottobratica）和锡诺波列塞（Sinopolese），以及七个外来品种：科拉蒂纳（Coratina）、伊特拉纳（Itrana）、莱基诺（Leccino）、墨西拿诺切拉（Nocellara Messinese）、诺恰拉（Nociara）、彭多利诺（Pendolino）和皮肖林（Picholine）。薄层色谱 - 气相色谱（TLC - GC）技术实现了脂肪醇化合物的分离与分析。在三个月的采样期间发现脂肪醇含量普遍下降，其中二十六醇最为明显。彭多利诺品种的下降最为显著。奇数链脂肪醇的下降不太明显，主要是二十七醇。收获日期和品种均对脂肪醇含量有显著影响。这是关于意大利南部卡拉布里亚西南部生产的橄榄油在成熟过程中脂肪醇变化的首份报告。
