摘要: 对多花黑麦草等28种牧草样品进行了脂肪酸组成的测定,并进行分析比较。结果表明,α-亚麻酸是牧草中含量最高的脂肪酸,占脂肪酸组成的43.78%。多不饱和脂肪酸占牧草脂肪酸组成的54.71%,占不饱和性脂肪酸的95.18%。说明牧草的不饱和性脂肪酸主要是二键以上的多不饱和脂肪酸。禾本科牧草中,多花黑麦草及狼尾草属的牧草α-亚麻酸含量较高,其中多花黑麦草69.9%;象草(N51)67.6%;红象草62.2%;杂交狼尾草61.0%。禾本科与豆科牧草的α-亚麻酸含量差异不显著。

Abstract: The fatty acids were determined, analyzed and compared at the same time in twenty-eight forages. Alpha linolenic acid was the most abundant fatty acid in the forage, making up to 43.78% of the fatty acids. The polyunsaturated fatty acids comprised 54.71% of the fatty acids, and 95.18% of the unsaturated fatty acids, indicating that the unsaturated fatty acids in the forage were dominated by the polyunsaturated fatty acids that had double bonds or more. In the grasses, Lolium multiflorum and Pennisetum had a high alpha linolenic acid content. In L. multiflorum the content was 69.9%, in P. purpureum cv. N51 it was 67.6%, in P. purpureum cv. Red it was 62.2%, and in P. americanum×P. purpureum it was 61.0%. There was no significant difference in the content of alpha linolenic acid between Gramineae and Leguminous forages.
