摘要
采用高效毛细管电泳仪,对高丛越橘和半高丛越橘品种的糖酸组分和含量进行了分析。结果表明,越橘品种的果糖含量在21.38-45.13mg·g^-1之间,平均为31.72mg·g^-1;葡萄糖含量在20.53-45.79mg·g^-1之间,平均为31.20mg·g^-1;果糖和葡萄糖含量的比值为1︰1.02。苹果酸含量在0.16-3.73mg·g^-1之间,平均为0.61mg·g^-1;柠檬酸含量在1.50-13.13mg·g^-1之间,平均为7.31mg·g^-1;柠檬酸含量占总酸含量的92.30%,说明越橘品种有机酸以柠檬酸为主。越橘品种间糖和有机酸含量的变异系数在14.25%-95.45%之间,高丛越橘种内各组分变异大于半高丛越橘;各糖酸组分比较,果糖变异最小,苹果酸变异最大。
Components and contents of sugar and organic acid in highbush and half-highbush blueberry fruits were analyzed by capillary electrohoresis. The results indicated that average content of fructose was 31.72 mg · g^-1,which ranged from 21.38 mg · g^-1 to 45.13 mg · g^-1 and that of glucose was 31.20 mg · g^-1,which ranged from 20.53 mg · g^-1 to 45.79 mg · g^-1. The ratio of fructose and glucose was 1︰1.02. Average content of malic acid was 0.61 mg · g^-1,which ranged from 0.16 to 3.73 mg · g^-1 and that of citric acid 7.31 mg · g^-1,which ranged from 1.50 mg · g^-1 o 13.13 mg · g^-1. Major organic acid in blueberry fruits was citric acid（92.30% of total acid）. The coefficient of variation of contents of sugars and organic acids between the blueberry cultivars ranged from 14.25% to 95.45%. Component variation between highbush blueberry was larger than that between half-highbush blueberry. Compared all the sugar and organic acid components,the coefficient of variation of fructose was the smallest,and variation of malic acid was the largest.
