Abstract: Ethanol extracts from three varieties (  Tainong,,   Jinhuang, and  Guifei,) of mango seeds were evaluated for their antioxidant activities. The results showed that  Tainong, mango seeds had the highest content of total phenolics, followed by  Jinhuang, and  Guifei,. Each of these extracts had strong abilities to scavenge DPPH, ABTS and hydroxyl free radicals, reduce to iron (III), chelate iron (II) and inhibit lipid peroxidation, and among them,  Tainong, mango seeds revealed stronger free radical scavenging ability in a dose-dependant manner.
