以多酚提取量为指标，在单因素试验的基础上，通过响应面法优化了超声辅助提取胡麻粕中多酚的工艺条件。结果表明，超声辅助提取胡麻粕中多酚的最佳工艺条件为：以体积分数54%的乙醇溶液为提取剂，在料液比1∶20、超声功率240 W、提取温度57℃的条件下，提取40 min。在最佳工艺条件下，胡麻粕中多酚提取量为10.14 mg/g。
以多酚提取量為指標，在單因素試驗的基礎上，通過響應麵法優化瞭超聲輔助提取鬍痳粕中多酚的工藝條件。結果錶明，超聲輔助提取鬍痳粕中多酚的最佳工藝條件為：以體積分數54%的乙醇溶液為提取劑，在料液比1∶20、超聲功率240 W、提取溫度57℃的條件下，提取40 min。在最佳工藝條件下，鬍痳粕中多酚提取量為10.14 mg/g。

With extraction quantity of polyphenols as index, the ultrasound-assisted extraction conditions of polyphenols from flaxseed meal were optimized by response surface methodology based on single factor experiment. The results showed that the optimal ultrasound-assisted extraction conditions of polyphenols from flaxseed meal were obtained as follows:using ethanol with volume fraction 54% as extractant, ratio of solid to liquid 1∶20, ultrasonic power 240 W, extraction temperature 57℃, extraction time 40 min. Under these conditions, the extraction quantity of polyphenols was 10. 14 mg/g.
