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.

Key words: ultrasonic-assisted extraction, total polyphenols, pomegranate peels
