摘要:

采用螯合剂辅助乙醇从石榴籽中提取黄酮,并用正交试验筛选最佳提取条件。结果表明:在提取液中添加螯合剂,提高了石榴籽黄酮的溶出率;提取石榴籽黄酮的最佳工艺参数为提取温度70℃、乙醇体积分数70%、料液比1:25(g/ml)、六偏磷酸钠(SH)添加量0.4%。在此优化提取条件下,黄酮提取率为0.881%(m/m)。

Abstract:

Extraction of flavonoids from pomegranate seeds using ethanol associated with a chelate, sodium hexametahposphate (SH), was optimized through orthogonal experiments. The optimal extraction condition was 70 ℃ of extraction temperature, 70% ethanol, 1:25 (g/ml) of material-liquid ratio and 0.4% SH. The extraction rate of flavonoids achieved up to 0.88% (m/m) under this optimal condition.

Key words: pomegranate seed, flavonoid, chelator, optimization
