Abstract:

Objective: To set up an examination method for determining saccharides in blueberry juice by HPLC. Method: Saccharides were extracted from samples with water using ultrasonic, and then their components and contents were determined by HPLC. Agilent Zorbax carbohydrate (4.6 × 250 mm, 5 μm) column was adopted, mobile phase was acetonitrile-water (75:25, V:V), and the flow rate was 1 ml/min. Results: The calibration curve of saccharide concentrations is well linear in the range of 0.5 to 10 mg/ml, the correlation coefficient is over 0.9989 (n=5), the RSD is 0.36% to 2.18% (n=5) in precision experiment, and the average recovery rate is 91.36% to 101.34%. Conclusion: This method is convenient, rapid and effective for separation and quantitative analysis of saccharides in blueberry juice.
