摘要
采用盐酸水解法分析不同来源仙草的氨基酸组成及含量差异,结果表明供试仙草均含有17种氨基酸和7种必需氨基酸,氨基酸总量为4.75%～13.65%1,7种氨基酸总量和7种必需氨基酸总量的高低顺序都是9>10>5>8>1>6>4>3>2>7,均以9号仙草含量最高7,号仙草最低。各种氨基酸含量高低顺序相似,以谷氨酸、天门冬氨酸、亮氨酸含量居前三位,胱氨酸含量最少。不同来源仙草的必需氨基酸与非必需氨基酸比值超过0.6,符合FAO/WHO提出的参考蛋白模式,仙草具有更高的营养价值和开发利用价值。
To study the amino acids content and composition in Mesona chinensis from different producing areas by hydrochloric acid hydrolysis method.The results showed that all the samples contained 17 kinds of total amino acids and 7 kinds of essential amino acids,amino acid contents ranging from 4.75% to 13.65%.The total amino acids and the essential amino acids both decreased in order of 9,10,5,8,1,6,4,3,2,and 7.The decreasing order of all amino acid content were similar,the three highest amino acid content was glutamic acid,aspartic acid and leucine.Cystine was in the lowest content.The ratio of inessential amino acids to non-essential amino acid of different Mesona chinensis was more than 0.6.It is accordant with the reference protein pattern presented by Food and Agriculture Organization and World Health Organization.Thus,Mesona chinensis has high potential development value.
