Evaluation of Antioxidant Capacity of Two Ocimum Species
The antioxidant activities of Ocimum basilicum and Ocimum gratissimum consumed as spices in Nigeria were evaluated in a bid to provide better scientific basis for increased domestication efforts on them. Total phenol and flavonoid contents of the spice extracts ranged from 9.09 - 27.41 μg GAE/mg and 5.38 - 22.88 μg RE/mg respectively.

Free radical scavenging and total antioxidant capacity
Methanol (0.3 ml) in the place of extract was used as the blank. The antioxidant activity is expressed as the number of gram equivalent of ascorbic acid. The calibration curve was prepared by mixing ascorbic (1000, 500, 250, 125, 62.5 and 31.25 µg/ml) with methanol. 2.5 Evaluation of total phenolics content using Folin-Ciocalteu reagent
