摘　　要：应用重量法和气相色谱-质谱联用技术(GC-M S)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。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.
