Osbeck to investigate antioxidant activity. The extracts of the leves and seeds were analyzed for total phenolic content, total flavonoides, Antioxidant activities, Reducing power, chelating ions and scavenging hydrogen peroxide. The ethanoic extracts of grapefruit was 373.2 GAE/ g dw shown superior amount of total phenolic compounds, scavenging of Hydrogen peroxide 95.1% , chelating of ferrous ion 70.8%, sour orange seeds extract had higher flavonides
( 371.3 mg/100g dw) compering with other four species, antioxidant activity of orange seeds was 70.5 mg/ml, and ethanol extracts of lemon seeds had maximum priority in reducing power was ( 220.2 %) Also the Increasing the concentration of the extracts led to increase of exhibited inhibition of peroxidation in linoleic acid system.
