Abstract

    Antioxidant activity of various ginger extracts are different.  The aims of this work are to determine the antioxidant activity of ginger extracts on linoleic acid. The antioxidant activities were tested on  linoleic acid supplemented with water and dichloromethane extract of ginger.   The antioxidant  activity was tested by measuring malonaldehide absorbance.  Total phenol and iron content  of the extracts were analyzed by spectrometry.  This research showed that antioxidant activity of water and dichloromethane extract of ginger was stronger than a-tocopherol, and antioxidant activity of dichloromethane extract is stronger than water extract of ginger.  Antioxidant activity of ginger extracts, seems to be correlated with  the  total phenol and iron contents.
