| 中文摘要: |
| 对麻花艽种子营养成分进行分析测定。结果表明：麻花艽种子中水分、总黄酮、总糖、粗脂肪、粗蛋白、粗纤维含量分别为6.95%、0.22%、2.57%、17.50%、20.53%、23.57%，为高蛋白、高纤维植物种子；16种氨基酸总量为21.84 g/100 g，其中谷氨酸(5.46 g/100 g)含量最高；常量元素中钾（4 300 mg/kg）含量最高，钙（803 mg/kg）含量最低，微量元素中铁（227 mg/kg）含量最高，铜（12.7 mg/kg）含量最低；共检出17种脂肪酸，不饱和脂肪酸含量占总脂肪酸的84.54%。研究表明，麻花艽种子具有较高的蛋白质含量，氨基酸组成全面，矿质元素丰富，油酸、亚油酸等不饱和脂肪酸含量高，因此极具开发利用价值。 |

| 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. |
