摘要: 通过网络药理学和分子对接技术, 研究莲须抗氧化的分子机制, 并通过实验体外验证莲须清除自由基的能力. 结果表明: 莲须的抗氧化作用主要依赖于MAPKs信号通路和PI3K/AKT信号通路等生物过程调节;   莲须对1,1-二苯基-2-三硝基苯肼自由基(DPPH.)和羟基自由基(.OH)有一定的清除能力, 当质量浓度为0.8 mg/L时,对DPPH..OH的清除率分别为83.6%和53.43%;高效液相色谱(HPLC)检测发现莲须中包含山奈酚、 木犀草素和槲皮素等黄酮类化合物发挥抗氧化作用.

Abstract: We studied the  molecular mechanism of antioxidative activity of stamen nelumbinis   by network pharmacology and molecular docking technology,  and  verified the free radical scavenging ability of stamen nelumbinis  through  in vitro experiments. The results show  that the antioxidant effects of stamen nelumbinis   mainly relies on the regulation of biological processes such as MAPKs signaling pathway and PI3K/AKT signaling pathway. The stamen nelumbinis  has a certain ability to clear 1,1-diphenyl-2-picrylhydrazyl radical (DPPH.) and hydroxyl radical (.OH),  and the scavenging rates of DPPH. and .OH are 83.6% and 53.43%,  respectively when the mass concentration is 0.8 mg/L. The high performance liquid chromatography (HPLC) detection reveals that the stamen nelumbinis  contains flavonoids such as kaempferol,  lignans,  and quercetin, which exert antioxidant effects.
