摘要本研究旨在探讨圆形榛子(Corylus avellena L.)在土耳其使用脂肪酸(FA)成分。这些样本是在2015年至2016年期间从黑海西部、中部和东部地区收集的。经气相色谱分析，脂肪酸组成以油酸(C18：1)最丰富，其次为亚油酸(C18：2)、棕榈酸(C16：0)和硬脂酸(C18：1)。采用单因素方差分析和线性判别分析方法，对不同产地的榛子油的脂肪酸组成进行了统计分析。结果表明，黑海中部地区总饱和脂肪酸含量较高(8.45%)，总单不饱和脂肪酸含量较高(83.54%)，多不饱和脂肪酸总量较低(7.85%)，东部黑海地区亚油酸(%9.10)和亚麻酸(%0.096)含量较高。LDA鉴定的6种脂肪酸(C16：1、C18：1、C18：2、C18：3、C20：0和C20：1)提供了86.2%的正确预测。
Abstract This study focuses on detecting geographical origin of round type hazelnut (Corylus avellena L.) in Turkey using fatty acid (FA) composition. The samples were collected from Western, Central, and Eastern Black Sea regions between 2015 and 2016. FA profiles were determined by gas chromatography (GC), and most abundant fatty acid was oleic acid (C18:1) followed by linoleic acid (C18:2), palmitic acid (C16:0), and stearic acid (C18:1). The effect of geographical origin on the fatty acid profile of hazelnut oils was statistically analyzed by one‐way ANOVA and linear discriminant analysis (LDA). The results showed that the Central Black Sea region had high content of total saturated fatty acids (%8.45), total monounsaturated fatty acids (%83.54), low content of total polyunsaturated fatty acids (%7.85), and Eastern Black Sea region had high content of linoleic (%9.10) and linolenic acid (%0.096). Six fatty acids (C16:1, C18:1, C18:2, C18:3, C20:0, and C20:1) identified by LDA provide 86.2% of correct predictions.
