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.
