中文摘要:

      目的 探究不同来源天冬中氨基酸的种类和含量。方法 建立柱后茚三酮衍生光度法, 测定广西天冬、内江天冬、西南天冬中氨基酸的种类和含量, 并利用化学计量学方法进行数据分析。结果 内江天冬中氨基酸平均含量为3.06%, 广西天冬中氨基酸平均含量为3.53%, 西南天冬中氨基酸平均含量为5.73%。内江天冬与广西天冬中的氨基酸组成和含量相近, 不同批次间含量均匀, 西南天冬与前两个来源天冬氨基酸含量存在较大差异, 不同批次间差异较大。结论 本研究为天冬质量评价及其道地性研究提供了科学参考。

英文摘要:

      Objective To explore the types and contents of amino acids in Asparagus from different sources. Methods Post-column ninhydrin-derived photometry was established to determine the species and contents of amino acids in Guangxi, Neijiang and southwest winter, and performed data analysis using stoichiometry. Results The average amino acid content in Neijiang was 3.06%, 3.53% in Guangxi, and 5.73% in southwest China. The amino acid composition and content in Neijiang and Guangxi were similar, and the content was uniform among different batches, the amino acid content in southwest and southwest was quite different from the first two sources, and the different batches were quite different. Conclusion This research provides scientific reference for quality evaluation of Asparagus and the study of its authenticity.
