摘要
测定了2007—2010年来自9个产地59个品种共97份燕麦样品的油脂含量和脂肪酸相对含量。以此为基础,分析了产地、年份间的差异,并对燕麦样品进行了聚类分析。结果显示:燕麦中油脂平均含量为6.42%,受年份影响显著,而产地影响不显著;燕麦油脂脂肪酸主要成分油酸、亚油酸比例接近1∶1,约占总脂肪酸的80%,脂肪酸组成受产地、年份影响均显著;所收集燕麦样品根据所测定油脂指标可聚为3类,但类间差异主要体现在油酸含量上。
Ninty - seven oat samples of 59 varieties from 9 locations harvested from 2007--2010 were collected. Oil content and fatty acids composition of the samples were determined, and the differences among years and locations were analyzed. Meanwhile cluster analysis was employed in oat samples classification. The results indicated that the average content of oil in oats was 6. 42% ; locations had no significant effect on oil content, but years had significant effect. Oleic acid and linoleic acid took up 80% of fatty acids in oat oil, and their ratio was close to 1： 1. Both locations and years had significant effects on fatty acids composition. Oat samples were classified into 3 categories, the differences among categories were mainly reflected in oleic acid.
