摘要： Change in soluble sugar and organic acids of dragon fruit wine during fermentation by reversed phase high performance liquid chromatography (RP-HPLC); Organic acids chromatographic conditions: chromatographic column BP-OA, mobile phase A(1% H3PO4) and B (UPW), column temperature 25 degrees C, the flow rate of 0.5 ml/min, UV detector (210 nm). Sugar chromatographic conditions: BP-OA chromatographic column, mobile phase(UPW), column temperature 25 degrees C, the flow rate of 0.3 ml/min, differential detector. The results showed that the degree of separation of components in 1.44 above, RSD was between 0.6% and 2.7%, the average recovery is between 93.4% to 108.4%.Citric acid and malic acid decrease by 71.02% and 71.30%, respectively, at the end of the fermentation. Lactic acid content increases 86.71%, succinic acid and acetic acid content increased, but pyruvicrise after falling.Sucrose and glucosefall by 78.54% and 59.06% respectively, fructose content increased by 95.23%.
