| 摘 要： | 从羟自由基清除率、还原力、抑制脂质过氧化能力和清除DPPH自由基等四个方面研究了旱莲草、积雪草、莱菔子、马齿苋、女贞子、枇杷核等六味中药水提物的体外抗氧化作用。结果显示,在羟自由基清除率方面,从强到弱清除能力依次是马齿苋、积雪草、旱莲草、枇杷核、女贞子和莱菔子。在还原力方面,六味中药从强至弱顺序依次是积雪草、马齿苋、旱莲草、枇杷核、女贞子和莱菔子。在抑制脂质过氧化方面,抗氧化能力从强到弱依次是马齿苋、女贞子、莱菔子、枇杷核、积雪草和旱莲草。在DPPH自由基方面,其清除能力从大到小依次是积雪草、马齿苋、枇杷核、旱莲草、女贞子和莱菔子。结论表明,六味中药的水提物均具有一定的体外抗氧化活性。
