苜蓿不同部位的氨基酸组成及含量分析

目的]为苜蓿的深度开发利用提供理论依据。方法]利用氨基酸自动分析仪测定分析苜蓿的茎、叶和种子的氨基酸成分和含量。结果]结果表明,苜蓿中氨基酸含量丰富,叶和茎中含有18种氨基酸,种子含有17种氨基酸。不同苜蓿品种间,同一品种不同部位间氨基酸含量差异较大。苜蓿叶片、茎和种子中氨基酸含量占干重比例分别为30.43%、24.44%和18.31%。必需氨基酸和非必需氨基酸比较分析结果表明,苜蓿叶片具有较高的营养价值。结论]苜蓿具有更高的营养价值和开发利用价值。

Analysis of Amino Acids Compositions and Contents in Different Parts of Alfalfa

Objective] The purpose was to provide theoretical basis for exploitation and use of Alfalfa.Method] The compositions and contents of amino acids in the neck,leaf and seed of Alfalfa were analyzed with amino acid auto analyzer.Result]The results indicated that the contents of amino acids of Alfalfa are abundant.The differences of contents of amino acids between different varieties and different parts of Alfalfa were large.The percentages on the dry weight of amino acids in the leaf,neck and seed of Alfalfa were 30.43%,24.44% and 18.31%.The analyzed results of essential amino acid and non-essential amino acid indicated that Alfalfa leaf had higher nutritional values.Conclusion] The Alfalfa has the higher nutritional value and the development use value.
