| Abstract: |
| The nutrient components of the Gentiana straminea Maxim. seeds were analyzed and determined. The results showed that the contents of moisture, total flavonoids, total sugar, crude fat, crude protein and crude fiber in the G. straminea seeds were 6.95%, 0.22%, 2.57%, 17.50%, 20.53% and 2357%, respectively, which were high protein and high fiber plants seeds. The content of total 16 amino acids was 21.84 g/100 g, of which glutamic acid (5.46 g/100 g) was the highest.The content of K (4 300 mg/kg) was the highest in macroelement, and the content of Ca(803 mg/kg) was the lowest. The content of Fe (227 mg/kg) was the highest in trace elements, and the content of Cu (12.7 mg/kg) was the lowest. A total of 17 fatty acids were detected, and the content of unsaturated fatty acids accounted for 84.54%. The results indicated that the G.straminea seeds had higher protein, comprehensive amino acid composition, rich mineral elements, high content of unsaturated fatty acids such as oleic acid and linoleic acid, so it had great value for deve lopment and utilization. |
