Fruit Quality and Constituent of Sugars and Organic Acids in Wampee Cultivars

Fruit quality and constituent of sugars and organic acids in 9 wampee cultivars were analyzed by traditional quality analysis and high performance liquid chromatography(HPLC).The results showed that the major components of soluble sugars in wampee fruits were fructose,glucose and sucrose,and the fructose content was the highest,followed by glucose and sucrose.Based on the distribution of soluble sugars,wampee was classified as monosaccharide prevalent.The difference of sugars/acids among cultivars was mainly based on the content of organic acids.The major parts of organic acids in wampee were malic acid and citric acid,and wampee could be easily classified as malic acid dominant and citric acid dominant.'Tianye'and'Daguotianjixin'could be considered as the best wampee cultivars with quality fruit.
