Abstract


This work evaluates the antioxidant potential of Monodora myristica (African nutmeg). Monodora myristica extract was obtained by solvent extraction using n-hexane and used as treatment on freshly prepared crude palm kernel oil and palm oil. Equal volume of oil samples were subjected to different concentration of extract treatment (0.2ml,0.4ml, 0.6ml, 0.8ml, 1.0ml using syringe. These oil samples were equally divided into two groups SS and SR. Group SS was stored under the sun and group SR  was stored in the room for three weeks. These treated oil samples were analyzed on weekly basis at two different parameters: Acid value (AV) of free fatty acid and thiobarbituric acid (TBA) value, using standard methods. The main effect of extract was determined using ANOVA. For the two varieties of oil, the acid value of free fatty acid increased significantly (P<0.05) as the period extends for group SS without extract while those for group SR showed no significant increase. But AV of oil samples treated with higher extract concentration decreased significantly (P<0.05) for both groups SS and SR. TBA value also showed the same trend of AV. Hence, monodora myristica extract yielded reducing effect in the oxidative level of the oil varieties.
