Abstract

Abstract:

Six potherbs including Chenopodium album linn, Pteridum aquilinum var latiusculum, purslane, Picris divaricata vaniot, water cress and Bengal waterdropwort from Guizhou were extracted with ethanol or water and the extracts were tested for their hydroxyl and DPPH free radical scavenging capabilities. Meanwhile, the IC50 values as determined using rapeseed oil and lard as antioxidant models were used to evaluate their antioxidant activity. The results indicated that the 6 potherbs exhibited high hydroxyl and DPPH free radical scavenging capabilities and had excellent antioxidant effects on rapeseed oil and lard. However, added Bengal waterdropwort could accelerate oxidantion of rapeseed oil and lard.

Key words: potherbs from Guizhou, hydroxyl free radicals, DPPH free radical, edible oil, antioxidation
