摘要:采用正交试验法研究了海南蒲桃叶黄酮提取条件对黄酮得率的影响,确定了最佳提取条件为:乙醇体积分数70%,料液比1∶20(g∶mL),提取温度80℃提取3h,此条件下黄酮得率为6.06%。利用体外试验检测不同浓度海南蒲桃叶黄酮对二苯基苦基苯肼DPPH.的清除作用。结果表明海南蒲桃叶黄酮是一种有效的自由基清除剂,对DPPH.有显著的清除作用。黄酮溶液质量浓度在31.25~250mg/L范围内,清除率随质量浓度增大而增大,最高可达93.04%。
Orthogonal experiments were applied to optimize the extraction conditions for flavones from Syzygium cumini Linn. Skeels leaves. The optimum extraction conditions were : ethanol volume fraction 70 % , raw material to liquid ratio 1 : 20( g : mL), extraction temperature 80 ℃, extraction time 3 h, and the yield of flavones was 6.06 %. The in vitro-oxidation effect on DPPH · was investigated. The results showed that S. cumini leaves was an effective free radical scavenger, and had a significant scavenging effect. The elimination rate increase with the increase of flavones concentration within the range of 31.25-250 mg/L. It can reach the highest value of 93.04 %.
