METHODS: The nutmeg and megkudu essential oils were obtained by steam distillation. The antioxidant activities of both essential oils were determined by beta-carotene/linoleic acid bleaching assay and reducing power while the anti-angiogenic activity was investigated using rat aortic ring assay using various concentrations.

RESULTS: The results showed that nutmeg oil has higher antioxidant activity than mengkudu oil. The nutmeg oil effectively inhibited the oxidation of linoleic acid with (88.68±0.1)% while the inhibition percentage of oxidation of linoleic acid of the mengkudu oil is (69.44±0.4)%. The nutmeg oil and mengkudu oil showed reducing power with an EC(50) value of 181.4 μg/mL and 3 043.0 μg/mL, respectively. The antiangiogenic activity of nutmeg oil showed significant antiangiogenic activity with IC(50) of 77.64 μg/mL comparing to mengkudu oil which exhibits IC(50) of 109.30 μg/mL.
