      Objective To establish a method for the determination of biogenic amines in peach wines by ultra performance liquid chromatography, and analyze the composition and content of biogenic amines in different varieties peach wines. Methods The samples were derivatized by dansyl chloride and then extracted with ethyl acetate liquid-liquid extraction, separated by Waters ACQUITY UPLC BEH C18 column (100 mm×2.1 mm, 1.7 μm) under 35℃, with the acetonitrile-0.1% acetic acid aqueous solution as mobile phase at a flow rate of 0.2 mL/min. Ultraviolet detection wavelength was 254 nm, and external standard method was performed for the quantification. Results Eight kinds of biogenic amines including tryptamine, β-phenylethylamine, tyramine, putrescine, cadaverine, histamine, spermine, and spermidine were determined by pre-column derivatization using dansyl chloride combined with ultra performance liquid chromatography-ultraviolet spectrophotometry within 16 min, the peak areas of 8 kinds of biogenic amines had good linear relationships with mass concentrations in the range of 1.0?50.0 mg/L, with the correlation coefficient r2>0.999, the limits of detection and quantification ranged at 15.76?21.43 and 53.58?71.07 μg/L, respectively, and the intra-day precision and inter-day precision ranged at 0.85%?3.31% and 1.02%?4.36%, respectively; the recoveries ranged at 89.71%-106.16%. All the 8 kinds of biogenic amines could be detected in the different varieties peach wine samples. Among which, tryptamine and putrescine showed higher levels in peach wine samples, while tyramine and spermine showed lower levels in most samples. Peach wines made from 2 cultivars of Biafeng and Wuhan had higher levels of biogenic amines, whereas Chunmi and Zhongtaofeiyu peach wines showed lower levels of biogenic amines than other varieties. Conclusion This method is rapid, simple, sensitive, efficient, accurate and reproducible, and can be used for the determination of biogenic amines in peach wines. There is great difference in biogenic amine profiles among peach wines made from different varieties, so selection of suitable variety of peach may be a helpful approach to control the content of biogenic amines in peach wine.
