AQC柱前衍生化高效液相色谱法测定宝乐果中的游离氨基酸
Application AQC as a Pre-column Derivatization Reagent for HPLC Determination of Free Amino Acids in Borojo sorbilis Cuter.
摘要
Abstract
To determine and analyze free amino acids in Borojo.The sample was derivatized with 6-aminoquinolyl-N-hydroxysuccinimidyl carbamate (AQC) and then was analyzed with high-performance liquid chromatography (HPLC).HPLC was performed on a Phenomenex C18 (250mm × 4.6 mm,5 μm) column with gradient elution of deionized water (A),acetonitrile (B) and 10 mmol/L ammonium acetate buffer solution (adjusted to pH 5.10 with glacial acetic acid) (C) at the flow rate of 0.8 ~1.0 mL/min,detected with Ultra Voilet (UV) at 248 nm.Linear relationship equations were obtained with 18kinds of amino acids in the range of 0.02 ~ 0.5 mmoL/L,and their correlation coefficients were in the range of 0.998 3 ~ 0.999 2.Fourteen amino acids were detected and average recoveries of those added were in the range of 96.9 % ~ 106.9 % and RSD values were in the range of 0.67 % ~ 3.07 %.The method could be used for determination of content of free amino acids in Borojo.关键词
