摘要:
为了研究不同产地乌饭树叶中游离氨基酸综合品质的差异,该研究以5个产地的乌饭树为对象,采用氨基酸自动分析仪对乌饭树叶中游离氨基酸种类和含量进行测定,利用主成分分析法进行综合评价。结果表明:乌饭树叶中游离氨基酸种类丰富,共检测出27种游离氨基酸,其中包括7种人体必需氨基酸;总游离氨基酸在0.346 —1.184 mg/g之间。不同产地间乌饭树叶游离氨基酸组成和含量存在差异。通过主成分分析提取 3 个主成分,累计方差贡献率为88.027%。综合评价5个产地乌饭树叶游离氨基酸综合品质的优劣顺序为:安徽宣城>江苏溧阳>湖南白云山>江西上犹>安徽黄山。
Abstract:
In order to analyze the differences in the comprehensive quality of free amino acids in the leaves of Vaccinium bracteatum from different producing areas,the free amino acids were determined by automatic amino acid analyzer,and thesystematic evaluation were performed by principal component analysis and subordinate fuction method.The results showed that the total free amino acids ranged from 0.346 mg/g to 1.184 mg/g. The V. bracteatum leaves from different producing areas contained 27 kinds of free amino acids, with 7 kinds of essential amino acids. There were differences in the kinds and contents of amino acid among different producing areas. Three principal components were extracted by principal component analysis, and the cumulative variance contribution rate was 88.027%. The V. bracteatum quality based on free amino acid content was shown in order as Xuancheng in Anhui, Liyang in Jiangsu, Mount Baiyun in Hunan, Shangyou in Jiangxi and Mount Huang in Anhui.
