| 摘 要： | 本文采用高速氨基酸自动分析仪对太子参四大种植主产区(安徽、江苏、福建、贵州)的栽培品及河南的野生品,共13个批次太子参药材的氨基酸组成和含量进行测定。结果显示氨基酸含量基本顺序为:精氨酸(Arg)>谷氨酸(Glu)>天冬氨酸(Asp)>脯氨酸(Pro),其中安徽宣城产太子参样品(S2)的16种氨基酸总含量和7种人体必需氨基酸含量最高。以上述4种主要氨基酸作为指标,探讨了不同产区太子参药材的内在品质。采用聚类分析法对氨基酸含量进行多元统计分析,表明氨基酸含量分析可体现样品产区间和产区内的差异性,可区别野生品与栽培品。这些结果为发展太子参道地药材的质量标准控制提供了依据。 |

| Abstract: | The contents and composition of amino acids in 13 bathes of Pseudostellaria heterpphylla(collected from Anhui,Jiangsu,Fujian,Guizou and Henan) were determined by HITACH IL8800 high speed amino acid analyzer.The results showed main sequence of amino acid content was arginine(Arg) > glutamic acid(Glu) > aspartic acid(Asp) > proline(Pro).The total contents of 16 amino acids and essential amino acids were highest in samples collected from xuancheng(Anhui province).In order to discuss the intrinsic quality of these samples,the Arg,Glu,Asp and Pro were analyzed and compared as the quality index.In addition,the multivariate statistical method was used to analyze the differences of samples from different origins and the differences between wild and cultivated samples.These results could be used as references for the quality standard control of P.heterpphylla. |
