| Abstract: | 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. |
