| 摘 要： | 采用四种化学发光体系和两种比色体系研究鼠尾草叶提取物直接清除自由基的能力。结果表明,鼠尾草叶提取物能有效地清除O2·、·OH和DPPH·,减轻或消除·OH对DNA的氧化损伤,抑制脂质过氧化。因此鼠尾草叶提取物是有效的、多功能的天然抗氧化剂和自由基清除剂,是值得进一步开发利用的天然产物。

| Abstract: | Extracts of Salvia officinalis leaves were investigated for their radical scavenging activity by using four chemiluminescence systems and two colorimetric systems. The results showed that extracts of Salvia officinalis could effectively scavenge O2·, ·OH and DPPH·, reduce or prevent DNA oxidative damage caused by ·OH and inhibit lipid pexoxidation. The present study suggests that extracts of Salvia officinalis are effective and of multifunctional natural antioxidants and radical scavenger, so it is a kind of natural plant that is worthy of being further exploited and utilized. |
