Antioxidant activity test of ethyl acetate total extract from Batak leeks (Allium chinense G. Don)

Abstract

The research with titled "Antioxidant activity test of ethyl acetate total extract from Batak leeks (Allium. chinense G. Don)" had been done. For the antioxidant activity test using UV Visible Spectrophotometer with 2,2-diphenyl-1-picrylhydrazyl (DPPH) as a scavenging agent obtained IC₅₀ ethyl acetate extract total batak leeks amounted to 52.39% mg / L which stated that the extract was strong antioxidant.
