Study on Scavenging Free Radical and Antioxidation Effects of Extracts from Salvia officinalis Leaves

Abstract

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.

Key words: extracts of Salvia officinalis leaves, free radical, DNA oxidative damage, antioxidant
