中文摘要: 该研究考察表面活性剂协同超声辅助提取白芷黄酮的工艺，并对其体外抗氧化能力进行分析。在单因素试验的基础上考察表面活性剂浓度、料液比、提取时间及提取温度对白芷黄酮得率的影响，并通过正交设计对白芷黄酮的提取工艺进行优化。结果表明：白芷黄酮超声提取最佳工艺为提取温度60℃、提取时间60 min、十二烷基硫酸钠浓度0.5% 、料液比1∶50（g/mL），在此条件下白芷黄酮得率为1.982% 。白芷黄酮对体外的自由基有较好的清除作用。
Abstract:The surfactant-assisted ultrasonic extraction process and antioxidant activity in vitro of flavonoids from Angelica dahurica were studied.On the basis of single factor experiments，the effects of surfactant sodium dodecyl sulfate concentration，solid-to-liquid ratio，extraction time，and extraction temperature on the yield of A.dahurica flavonoids were investigated，and the extraction process was optimized by orthogonal design.The optimal ultrasonic extraction conditions were extraction with 0.5% sodium dodecyl sulfate and solid-to-liquid ratio of 1∶50（g/mL）at 60℃ for 60 min.Under these conditions，the yield of flavonoids was 1.982% .The flavonoids of A.dahurica demonstrated good free radical scavenging activity.
