响应面法优化碱蒿黄酮提取工艺及其体外抗氧化作用OA北大核心CSCDCSTPCD
Optimization of Extraction Process for Flavonoids from Artemisia anethifolia Web. ex Stechm by Response Surface Methodology and Evaluation of Their Antioxidant Activity
用响应面法优化野生碱蒿黄酮类化合物的提取条件,通过羟自由基、超氧阴离子自由基、总还原力及脂质抗氧化实验测定碱蒿黄酮的体外抗氧化作用,并与抗坏血酸的抗氧化能力进行比较。结果表明提取工艺最佳条件为：提取温度80℃、提取时间1.75h、液料比27.5：1（mL/g）、提取2次,该条件下黄酮提取率预测值3.002%,验证值2.996%。对碱蒿黄酮的抗氧化研究表明,碱蒿黄酮对超氧阴离子自由基的清除作用与抗坏血酸比相对较弱,但对清除羟自由基、抗脂质体过氧化及…查看全部>>
Response surface methodology was employed to optimize the extraction of flavonoids from young stems and leaves ofArtemisia anethifolia Web. ex Stechm. Meanwhile, the antioxidant activity in vitro was evaluated by hydroxyl radical scavenging assay, superoxide anion radical scavenging assay, total reducing power assay, and anti-lipid peroxidation assay with vitamin C as the reference. The results indicated that the optimal extraction conditions were extraction…查看全部>>
