摘要: 本研究以乙醇为溶剂,以乙醇浓度、回流时间、回流温度等做L9(33)正交试验研究苦瓜中黄酮类物质的最优提取工艺,并比较了各提取液的抗氧化能力。实验结果表明:在乙醇浓度为70%,回流温度为40℃,回流时间为3h的条件下苦瓜中黄酮类物质的提取率最高126.56mg/100g,且其对·OH的清除率也最好75.37%,接近于VC对·OH的清除率80.10%。

Abstract: Optimize the conditions to extracting and antioxidant activity of flavonoids from Momordica charantia L.were studied by L9(33)orthogonal test.The results showed that the yield of flavonoids from Momordica charantia L.under optimal conditions(70% ethanol,40 ℃,3 h)is 126.56 mg/100g and its also have better function to scavenging· OH 75.37% close with VC(80.10%).
