摘　　要：大葱属于多年生草本植物,含有多种不同的成分。试验对14个大葱品种矿质元素和脂质成分进行了测定。结果表明:矿质元素中Cu、K和Mg元素含量最高的是4号;Mn元素含量最高的是青杂1号母本;B元素含量最高的是青杂1号父本;Zn元素含量最高的是青杂2号父本;Ca元素含量最高的是特选葱冠。脂质成分主要有碳酸二甲脂、碳酸二乙酯、(+/-)-3-羟基-r-丁内酯、草氨酸乙酯、亚硫酸二丙酯、肼基甲酸乙酯、甲基硫代磺酸甲酯和亚硫酸二乙酯等。试验对大葱各成分的提取和研究有着重要的意义。Welsh onion is a perennial herb containing various composltions. Assay some mineral elements anO aroma components on 14 Welsh onions cultivars. The results showed that different cultivars contained different main components in which Cu, K and Mg elements were the highest in No.4, Mn was the highest in Qingza 1 female parent, B was the highest in Qingza 1 male parent, Zn was the highest in Qingza 2 male parent, Ca content was the highest in Te xuan cong guan. A total of 59 aroma components were detected. There were mainly eight lipid compositions including carbonate dimethyl, diethyl carbonate, （＋/-）-3-hydroxy-R-butyl lactone, oxamate, sulfurous acid dipropyl, hydrazine ethyl carbamate, methyl thio sulfonic acid, sulfurous acid diethyl ester etc. This was importance for studies on components of Welsh onion, and provided a theoretical basis for the breeding of welsh onion.
