用甲酯化－气相色谱法测定了９１６份小米品种的脂肪酸含量。结果表明，在小米６种主要的脂肪酸中，亚油酸为７０．０１％，油酸为１３．３９％，亚麻酸为１．９６％，棕榈酸为８．３４％，硬脂酸为４．３８％，花生酸为１．７２％。小米不饱和脂肪酸总量为８５．５４％。聚类分析表明，我国小米亚油酸与不饱和脂肪酸含量，呈北方省份高，南方省份低的趋势。棕榈酸和饱和脂肪酸含量则是南方省份高于北方省份。
The fatty acid content of 916 millet varieties was determined by methyl esterification-gas chromatography. The results showed that among the six main fatty acids in millet, the content of linoleic acid was 70.01%, oleic acid was 13.39%, linolenic acid was 1.96%, palmitic acid was 8.34% and stearic acid was 4 .38%, arachidic acid is 1.72%. The total content of millet unsaturated fatty acids was 85.54%. Cluster analysis showed that the content of linoleic acid and unsaturated fatty acids in millet was high in northern provinces and low in southern provinces. Palmitic acid and saturated fatty acid content is higher in the southern provinces than the northern provinces.
