摘　　要：用高效液相色谱(HPLC)法测定皇帝蕉(贡蕉)、巴西蕉和粉蕉成熟果实中糖酸组分及含量。结果表明,成熟果实中均含有蔗糖、葡萄糖和果糖,并以积累蔗糖为主,皇帝蕉(贡蕉)、巴西蕉和粉蕉果实中蔗糖含量分别占总糖的59.76%、66.18%、68.69%,总糖含量大小表现为,皇帝蕉>巴西蕉>粉蕉;均含有11种有机酸,以苹果酸为主,含量分别占总酸的51.71%、47.30%、46.68%,同时含有大量的柠檬酸,分别占总酸的18.13%、19.62%和19.96%,并富含多种有机酸,总酸含量大小是粉蕉>巴西蕉>皇帝蕉。The components and contents of sugars and acids in three types of bananas （Gongjiao, Brazilitan, Fenjiao） were determined by HPLC methods. The results showed that the main components of sugars were sucrose, glucose and fructose, and most of the sugars were sucrose in mature fruit. The ratio of sucrose/total sugars was 59.76%, 66.18%, 68.69% in Gongjiao, Brazilitan and Fenjiao, respectively. The total sugar contents of Gongjiao were the highest, while that of Fenjiao were the least. There were 11 kinds of organic acids in Gongjiao, Brazilitan and Fenjiao, the major ones was malic acid-based. The ratio of malic acid/total acid was 51.71%, 47.30% and 46.68% respectively, while the ratio of citric acid/total acid was 18.13%, 19.62% and 19.96%, respectively. The contents of major organic acids or the total acids of Fenjiao were the highest, while those of Gongjiao were the least. This study would provide some reference for the quality evaluation of banana fruit.
