红树莓籽中黄酮提取工艺及抗氧化活性研究
Optimization of Extraction Technology of Flavonoids from Red Raspberry and Studies on Its antioxidant activity
摘要
Abstract
Red raspberry pomace was selected as the raw material.On the basis of single factors experiments,the Box-Behnken was used to study the extraction efficiency of flavonoids with the aid of ultra high pressure energy.The results show that the regression equation fit well with experimental data,the optimum conditions of extraction were:ethanol concentration 70%,ultra pressure 300 MPa,liquid-solid ratio 1 ∶ 30,extraction time 5 min.Under the optimal conditions,the experimental yield 38.6 mg/g was close to the predicted 55.7 mg/g.Results indicated that the flavonoids from raspberry seeds had an obvious antioxidant activity,the IC50 values of O2-· free radical scavenging abilities were 0.24 mg/mL.关键词
