摘要: 采用单因素和正交试验,考察提取溶剂、提取时间、提取温度、料液比等因素对石榴花多酚提取的影响。结果显示:石榴花中多酚的最佳提取条件为以体积分数60 %乙醇作溶剂、料液比1:20(g/mL)、温度50℃、提取时间1h;在该优化条件下提取,多酚粗提物的得率为44.20%、纯度46.19%,即石榴 花多酚得率达到20.42%。该方法操作简便、成本低、提取效果好,适合于工业化大生产。
英文摘要: To optimize the process conditions for the solvent extraction of polyphenols from the flower of pomegranate(Punica granatum L.)grown in Xinjiang,the effects of solvent type,extraction duration and temperature,and material/liquid ratio on polyphenol yield were studied by single factor and orthogonal array design experiments.The optimal extraction process for polyphenols from pomegranate flower was found to be based on the extraction with 20-fold volume of 60%aqueous ethanol solution at 50℃for 1 h,which gave 44.20%crude polyphenol yield and 46.19%product purity,20.42%pure polyphenol yield as calculated by multiplying them.The method is easy to operate,low-cost and highly efficient,thereby being suitable for the massive industrial production of polyphenols.
