Determination of Hydrolyzed Amino Acids by Hydrophilic Chromatography-Ultra high performance liquid-tandem mass spectrometry in Phyllanthus emblica Linn.

Abstract:Objective：To establis a method for the determination of hydrolyzed amino acids in the Phyllanthus emblica Linn. by hydrophilic chromatography-ultra-high performance liquid chromatography-tandem mass spectrometry. Methods：Hydrochloric acid was used to hydrolyze 17 amino acids in the P.emblica Linn., DE-52 cellulose was dechlorinated, and then a hydrophilic chromatography column was used in combination with ultra performance liquid chromatography-tandem mass spectrometry. Positive ion mode, multiple reactions monitoring (MRM), and external standard method were used for quantify 17 kinds of hydrolyzed amino acids in in the Phyllanthus emblica Linn.. Results：The results show that DE-52 cellulose can effectively remove the chloride ions in the hydrolysis solution, and the hydrophilic column has good separation effect for leucine and isoleucine. In the concentration range of 0.000 3-2.0 μg·mL-1, the linear relationship of 17 amino acids was good, the detection limit ranged from 0.015 to 13.0 mg·kg-1, the recovery ranged from 73.8% to 98.8%, and the relative standard deviation (RSD) range was 3.25%-7.79%. Conclusion：This method has good reproducibility and high sensitivity, and is suitable for the determination of 17 kinds of hydrolyzed amino acids in the P.emblica Linn..
