阿拉善地区５种荒漠植物种子营养成分研究GC-MS . Study on Nutrient Composition of Five Desert Plant Seeds in Alashan league

Abstract

Crude protein,crude fat and fatty acid were analyzed in the seeds of 5desert plants which were collected from Alashan league in Neimenggu.The test found that,crude protein content of 5desert plant seeds were around 19.83%-32.70%,the crude fat content were around 9.91%-18.53%.There were 11-12 fatty acids detected in seeds,the large proportion was unsaturated fatty acid(75.67%-88.20%),among which the linoleic acid were most abundant(53.37%-74.48%).The ration of polyunsaturated fatty acid to saturated fatty acid was 2.40-5.94.The results show that content of crude protein and crude fat in 5desert plant seeds were below average level of soybean,but higher than the other food crops.Significantly,fatty acid of seeds soil has cholesterol lowering functional,and a great value for exploitation and utilization.
