英文摘要:

      Objective To optimize the ultrasonic-assisted extraction of anthocyanins from Aronia melanocarpa. Methods Based on the single factor, the effects of extraction temperature, ratio of liquid to material and extraction time on the extraction rate of anthocyanin were studied. The extraction conditions of anthocyanins were optimized by response surface method. Results The optimum extraction conditions of anthocyanin from Aronia melanocarpa were as follows: concentration of ethanol solution (containing 0.5% acetic acid) was 40%, extraction temperature was 43 ℃, ultrasonic time was 23 min, and material-liquid ratio was 89:1 (V:m). Under this condition, the extraction yield of anthocyanin from the scopollutin of black fruit was (0.79±0.010) g/100 g. Conclusion This method can quickly and effectively extract the anthocyanins from Aronia melanocarpa.
