Rapid analysis of biogenic amines from rice wine with isotope-coded derivatization followed by high performance liquid chromatography-tandem mass spectrometry

A pair of isotope-coded derivatization reagents, d(0)-10-methyl-acridone-2-sulfonyl chloride (d(0)-MASC, light form) and d(3)-10-methyl-acridone-2-sulfonyl chloride (d(3)-MASC, heavy form), were used for labeling biogenic amines (BAs). On basis of the isotope-coded derivatization, a global isotope internal standard quantitative method for determining seven BAs by high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) was developed. The d(0)-MASC and d(3)-MASC can easily label BAs under mild conditions within 15 min at 50 degrees C. The obtained light and heavy labeled BAs were monitored by the transitions of [M+H](+) -> 208 and [M+H](+) -> 211, respectively. Relative quantification of BAs was achieved by calculation of the peak area ratios of d(0)-MASC/d(3)-MASC labeled derivatives. Excellent linear responses for relative quantification were observed in the range of 1/10-10/1. The developed method has been successfully applied to the quantification of BAs in Chinese rice wine with recoveries ranging from 94.9% to 104.5%. (C) 2015 Elsevier Ltd. All rights reserved.
