摘　　要：对陕西靖边引种油莎豆的一般成分(水分、灰分、淀粉、粗蛋白质、粗脂肪、还原糖、非还原糖和不溶性膳食纤维)、脂肪酸、氨基酸和矿质元素组成及含量进行分析,并对其营养价值进行评价。结果表明:陕西靖边油莎豆富含淀粉、非还原糖和粗脂肪,约占78%;油莎豆油含有12种脂肪酸,不饱和脂肪酸含量为84.16%,其中油酸含量高达74.20%,可作为生产油酸的原料;油莎豆蛋白氨基酸种类齐全,含量丰富;其矿质元素含量大小依次为Na>Mg>K>Ca>P>Fe>Zn>Mn>Cu。因此,陕西靖边油莎豆可以作为提取淀粉、糖和油脂的优良作物,具有广泛的发展前景和经济效益,适宜在陕北毛乌素沙漠地区推广种植。The general composition（ moisture,ash content,starch,crude protein,crude fat,reducing sugar,non-reducing sugar and insoluble dietary fiber） and compositions and contents of fatty acid,amino acid and mineral element of Cyperus esculentus introduced in Jingbian,shaanxi were analyzed and the nutritional value was evaluated. The results showed that Cyperus esculentus in Jingbian,Shaanxi was rich in starch,non-reducing sugar and crude fat,accounting for about 78%. Cyperus esculentus oil contained 12 kinds of fatty acids. The contents of unsaturated fatty acids and oleic acid were 84. 16% and74. 20% respectively,therefore Cyperus esculentus oil could be used to produce oleic acid. The type and content of amino acid in Cyperus esculentus protein were complete and abundant. The order of the contents of mineral elements in Cyperus esculentus was from high to low： Na,Mg,K,Ca,P,Fe,Zn,Mn and Cu. Therefore,Cyperus esculentus in Jingbian,Shaanxi could be used as an excellent crop to extract starch,sugar and oil with broad development prospect and economic benefit,which was suitable for being planted widely in the Muus Desert in northern Shaanxi.
