| Summary: | This study was conducted with the objective of evaluating the antioxidative activities of
extracts from different parts of Mengkudu (Morinda citrifolia L.) including leaf, fruit
and root. Methanol, petroleum ether, water and ethyl acetate were used as extraction
solvent. The antioxidative activities assays were done using ferric thiocyanate method
(FTC) and thiobarbituric acid test (TBA). Furthermore, the activities of these extracts
were then compared to that of a-tocopherol and butylated hydroxy! tolune (BHT). Effect
of solvent types and concentration of extract used on antioxidative activities of M. citrifolia were also carried out. |
