摘要

目的:研究32种不同杏仁(Prunus dulcis (Mill.))的脂肪酸组成。对采自土耳其安纳托利亚南部和东南部地区的d.a Webb)基因型种子进行了研究。方法:采用Hara和Radin(1978)的方法提取杏仁基因型的脂质。采用气相色谱法测定脂肪酸含量。采用SPSS 17.0统计软件对数据进行统计分析。结果:在气相色谱分析中，棕榈酸(16:0)、棕榈油酸(16:1)、硬脂酸(18:0)、油酸(18:1)、亚油酸(18:2)、亚麻酸(18:3)的含量分别为5.34%、0.70%、0.85%、74.46%、17.89%、0.75%。饱和脂肪酸(SFA)为6.19%，不饱和脂肪酸(USFA)为93.81%，USFA/SFA比值为15.40，单不饱和脂肪酸(MUFA)为75.16%，多不饱和脂肪酸(PUFA)为18.65%，MUFA/PUFA比值为4.32。在相关分析中，油酸与亚油酸的相关系数最高(r=-0.988)。聚类分析部分确定了杏仁样品之间的关系。结论:不同产地的杏仁基因型在脂肪酸组成上存在差异。此外，具有高油酸和低亚油酸等优质不饱和脂肪酸的杏仁基因型

Major fatty acids composition of 32 almond (Prunus dulcis (Mill.) D.A. Webb) genotypes distributed in East and Southeast of Anatolia

Objective: In this study, the fatty acid compositions of 32 different almond (Prunus dulcis (Mill.) D.A. Webb) genotypes seeds that collected from South and South East Anatolia regions in Turkey were studied. Methods: For lipid extraction of almond genotypes Hara and Radin (1978) method were used. Fatty acids content were determined using gas chromatographic (GC) analysis. The datas were evalulated with SPSS 17.0 statistical program. Results: In the gas chromatographic analysis, palmitic acid (16:0), palmitoleic acid (16:1), stearic acid (18:0), oleic acid (18:1), linoleic acid (18:2), and linolenic acid (18:3) were determined to be 5.34%, 0.70%, 0.85%, 74.46%, 17.89%, and 0.75% respectively. Saturated fatty acids (SFA) 6.19%, unsaturated fatty acids (USFA) 93.81% and a rate of USFA/SFA of 15.40, monounsaturated fatty acids (MUFA) 75.16%, polyunsaturated fatty acids (PUFA) 18.65% and a MUFA/PUFA ratio of 4.32 were found. In the correlation analysis, the highest correlation coefficient (r=-0.988) was detected between oleic acid and linoleic acid. Relationships among almond samples were partially identified with the cluster analysis. Conclusion: In this study, the variations were found between almond genotypes collected from different locations in terms of fatty acids compositions. Besides, the almond genotypes that have high quality unsaturates fatty acids such as high oleic acids and low linoleik acids content
