黄芪的抗氧化性研究。通过铜离子还原抗氧化能力（CUPRAC）和铁还原抗氧化能力（FRAP）方法测量大齿象溶剂提取物。结果表明，该植物的乙醇提取物具有较强的抗氧化活性。然而，该植物的水提取物具有较低的抗氧化潜力。此外，水和乙醇提取物显示较低的还原性抗氧化活性与FRAP方法的标准相比。同时，采用超高效液相色谱-电喷雾串联质谱（UHPLC-ESI-MS/MS）对植物叶片中的化学成分和含量进行了检测，检测出了高浓度的奎尼酸、对香豆酸和苹果酸。[图形]。
Antioxidant properties of Marrubium astracanicum subsp. macrodon solvent extracts were measured by both cupric ion reducing antioxidant capacity (CUPRAC) and ferric reducing antioxidant power (FRAP) methods. According to the results, ethanol extract of the plant has high potential of reducing antioxidant activity on CUPRAC method. However, water extract of the plant has lower antioxidant potential. Furthermore, both water and ethanol extracts showed lower reducing antioxidant activity compare to standards on FRAP method. Moreover, the composition and content of plant leaves were detected by UHPLC-ESI-MS/MS. High concentrations of quinic acid, p-coumaric acid and malic acid were determined.[GRAPHICS].
