Figure 3: Free-radical scavenging capacity of basil essential oils. The timedecay curves of the DPPH absorbance at 517 nm of the following basil essential oils are displayed: Large-leaved (L, 0.001% v/v), Small-leaved (S, 0.001% v/v), Lettuce-leaved (Le, 0.001% v/v), Red (R, 0.001% v/v), Lettuce-leaved flower (F, 0.005% v/v) and Cinnamon (C, 0.1% v/v). Double exponential fits are shown superimposed.
