AccQ·Tag柱前衍生反相-高效液相色谱法测定齿果酸模中的氨基酸含量
Determination of Amino Acid Contents in the Whole Plant of Rumex dentatus by Reversed-Phase High-Performance Liquid Chromatography with AccQ·Tag Pre-column Derivatization Method
摘要
Abstract
Objective: To determine the composition and contents of amino acids in the whole plant of Rumex dentatus for further study of its nutritional characteristics and food value.Methods: Amino acids were derivatized by 6-aminoquinolyl-N-hydroxysuccinimidyl-carbamate(AQC),and then their derivatives were separated on a Waters 515 HPLC system with a column temperature of 37 ℃ using phosphate buffer as mobile phase A and aqueous acetonitrile as mobile phase B in the gradient elution mode and detected at 248 nm using a UV detector.Results: Totally 17 amino acids were found,and the total content of amino acids in samples was 252.35 mg/g.The correlation coefficients of the calibration curves for 17 amino acids were all above 0.9995(n = 5).The average spike recoveries of 17 amino acids were between 97.1% and 102.6% with a relative standard deviation(RSD) between 0.3% and 3.26%(n = 3).关键词
