Abstract： Objective： To establish a method for determining the content of neotame in dry wine by high performance liquid chromatography by optimizing chromatographic conditions and sample pretreatment steps. Method： The samples were extracted with mixed extracts，concentrated and then analyzed by liquid chromatography. Result： Neotame showed a good linear relationship in the concentration range of 0.06μg?mL-1 to 6.00μg?mL-1 ，with a correlation coefficient of 0.999 6.The recoveries of neotame in dry wine at different spiked levels were 83.4% to 93.0% ，and the relative standard deviation （RSD） was <3% .Conclusion： This method is simple， rapid and accurate， suitable for large-scale sample detection，and has good practicality and promotion potential.
