从莲Nelumbo nucifera Gaertn.的雄蕊中分离的提取物和黄酮类化合物可抑制活性氧(ROS)的形成,抑制DPPH和脂质过氧化离子的活性,防治氧化应激引起的疾病。莲的雄蕊用水、甲醇、丁醇等极性溶剂或醋酸乙酯、正己烷、二氯甲烷或氯仿等非极性溶剂提取得到具抗氧化作用的粗提物。莲雄 Extracts and flavonoids isolated from the stamen of Nelumbo nucifera Gaertn. inhibit the formation of reactive oxygen species (ROS), inhibit the activity of DPPH and lipid peroxidation ions, and prevent oxidative stress-induced diseases. The stamens of lotus were extracted with a polar solvent such as water, methanol and butanol, or a non-polar solvent such as ethyl acetate, n-hexane, methylene chloride or chloroform to obtain a crude extract having antioxidant activity.
