| 摘 要： | 以石榴皮为原料，采用正交试验对石榴皮多酚的提取工艺进行研究。确定利用超声波辅助法提取石榴皮中多酚类物质的最佳工艺条件。结果表明：料液比1:20(g/mL)、30℃条件下超声波(固定功率100W)作用20min、提取1次，总多酚提取率最高，最终测定石榴皮多酚含量为14.06mg/g。

| Abstract: | The ultrasonic-assisted extraction of total polyphenols from pomegranate peels using 80% acidified ethanol as the extractant was optimized by orthogonal array design method.The highest extraction efficiency of total polyphenols from pomegranate peels,14.06 mg/g,was obtained after a single extraction at 30 ℃ and a solid-to-liquid ratio of 1:20(g/mL) based on ultrasonic treatment for 20 min at a power level of 100 W. |
