3种碱蓬属植物种子含油量及其脂肪酸组成研究

应用重量法和气相色谱-质谱联用技术（GC-MS）对吉林省西部盐碱地生长的碱蓬、角碱蓬和翅碱蓬3种野生植物的种子含油量及脂肪酸成分进行了测定和分析。结果表明：碱蓬、角碱蓬和翅碱蓬种子含油量分别为24．39％、15．67％和15．80％。不饱和脂肪酸含量分别为88．65％、88．30％、88．50％。尤其是亚油酸含量较高，分别达56．94％、59．35％和60．86％。利用盐碱荒地种植碱蓬属植物。充分开发其在食用、医疗保健方面的应用价值。具有巨大潜力和广阔前景。

Fat Contents and Fatty Acid Composition in the Seeds of Three species of Suaeda

Weight method and Gas chromatography-Mass spectrometry were adopted to determine the fat and fatty acid contents of the seeds of three wild plants, S. glauca, S. corniculata and S. salsa, which grew on saline-alkaline land of west Jilin Province. The results indicated that the fat contents of S. glauca, S. corniculata and S. salsa seeds respectively contained 24.39%, 15.67% and 15.80% fat, 88. 65%, 88. 30% and 88.50% fatty acids in their fat, and high linoleic oil contents among their unsaturated fatty acids, which amounted to 56.94%, 59.35%, and 60.86%, respectively. It is highly potential and significant to make use of saline-alkaline land for planting Suaeda plants and fully exploit their values in foods, medicines and healthy cares.
