中文摘要: 通过利用紫外分光光度计(ultraviolet spectrophotometer,UV)和气相色谱与质谱联用(gas chromatography coupled with mass spectrometry,GC-MS)分析红香木树皮浸泡酒的成分以及抗氧化活性,并且利用响应面分析模型对DPPH 自由基清除条件进行优化分析,预测的最优条件是液固比为20 ∶1(mL/g)、超声时间为21.65 min、超声功率为232.31 W,预测的最优清除率为95.15%。通过试验检验最优预测条件下的提取效果,清除率与预测值相接近,达到91.6%,仅相差3.56%。
Abstract:The composition and antioxidant activity of Anneslea fragrans Wall.bark soaked wine were analyzed by ultraviolet spectrophotometer(UV)and gas chromatography coupled with mass spectrometry(GC-MS).The DPPH free radical scavenging conditions were optimized by response surface analysis model.The optimal conditions for prediction were liquid-solid ratio 20 ∶1(mL/g),ultrasonic time was 21.65 min,ultrasonic power was 232.31 W,and the optimal removal rate was 95.15 %.The experiments about extraction effect under the optimal prediction conditions showed that the clearance rate was close to the predicted value,reaching 91.6%,with a difference of 3.56%.
