明月草营养成分的分析及评价

Analysis and Evaluation of Nutritional Components in Angelica keiskei

摘要:

对明月草的氨基酸、矿质元素及其他营养成分进行了分析测定，并进行了营养评价。结果表明，明月草中水分、蛋白质、粗脂肪、总糖、粗纤维、灰分、维生素C与总黄酮的含量为92.70%、1.99%、0.35%、0.21%、0.68%、1.40%、0.08 mg/g与4.79 mg/g；含有氨基酸15种，氨基酸总量(TAA)为20.01%。EAA/TAA为43.83%，EAA/NEAA为78.02%，各种人体必需氨基酸种类齐全，且比例均衡，比值系数分(SRC)为65.10。在各种人体必需氨基酸中，第一限制氨基酸为蛋氨酸+胱氨酸；P、K、Ca、Mg、Fe、Zn、Cu、Mn矿质元素的含量为322、4210、1441、478、38、2.36、1.14、55.70 mg/kg，经分析明月草氨基酸、矿质元素及其他营养成分含量丰富，具有很好的开发与利用价值。

Abstract:

Contents of nutritional components in Angelica keiskei were determined and evaluated including protein, crude fat, crude fiber, vitamin C, water, total ash, total sugar, total flavonoids, amino acid and mineral element. Results showed that the contents of water, protein, crude fat, total sugar, crude fiber, total ash, vitamin C and total flavonoids in angelica keiskei were 92.70%, 1.99%, 0.35%, 0.21%, 0.68%, 1.40%, 0.08 mg/g and 4.79 mg/g, respectively. Contents of fifteen amino acids,EAA/TAA ratio, and EAA/NEAA ratio were 20.01%, 43.83% and 78.02%, respectively. All kinds of human essential amino acids were found with a balanced proportion and the coefficient of amino acids was 65.10. The first limiting amino acids were Met and Cys in all human essential amino acids. The contents of phosphorus, kalium, calcium, magnesium, iron, zinc, cuprum and manganese in mineral elements were 322 mg/kg, 4210 mg/kg, 1441 mg/kg, 478 mg/kg, 38 mg/kg , 2.36 mg/kg, 1.14 mg/kg and 55.70 mg/kg, respectively. Angelica keiskei was rich in all kinds of nutritional components, which had better exploitation value.
