大庆盐碱地角碱蓬籽粒含油量及其脂肪酸组成研究

Fat Content and Fatty Acid Composition of Suaeda corniculata Seeds Produced from DaQing Salina

研究了黑龙江省大庆盐碱地角碱蓬籽粒含油量及其脂肪酸的组成,采用索氏提取法和气相色谱分析法对大庆市盐碱地生长的角碱蓬籽粒含油量及脂肪酸成分进行了测定及分析。结果表明:大庆市盐碱地生长的角碱蓬籽粒含油量为25.34%,其中棕榈酸为5.71%、棕榈油酸为2.05%、硬脂酸为0.07%、油酸为10.44%、亚油酸为80.03%、亚麻酸为1.69%,亚油酸含量最高,不饱和脂肪酸的含量占94.21%。大庆地区盐碱地角碱蓬亚油酸的含量远高于紫苏的含量,与月见草和红花籽油的含量相当,具有较高的开发和利用价值。

Soxhlet distilling method and gas chromatography were adopted to determine the fat and fatty acid contents of Suaeda corniculata seeds produced from Daqing Salina in Hei Longjiang Province. Results： The fat content of Suaeda corniculata seeds is 25.34%, the fatty acid composition is palmitic acid 5.71%, palmoleic acid 2.05%, stearic acid 0.07%, oleic acid 10.44%, linoleic acid 80.03%, and linolenic acid 1.69%. Linoleic acid is the main fatty acid, and the total unsaturated acids account for 94,21 %. The results provide scientific basis for the development and utilization of Suaeda corniculata produced from DaQing Salina in Hei Longjiang Province.
