Abstract： In this paper， 8 kinds of colorants in wine were determined by high performance liquid chromatography. The results showed that the linear relationship was good. The limits of detection were 0.01 mg·L-1， the limits of quantitation were 0.03 mg·L-1， the average recoveries were 88.5%～115.2%， and the relative standard deviations were 2.9%～6.3%.
