As far as chlorophyll is concerned, it is worth noting that this isoprenoid plant lipid may be both pro-oxidant, in the presence of light, and antioxidant in the dark. Endo, Usuki, and Kaneda (1985) reported that chlorophyll a shows the highest antioxidant activity with regard to chlorophyll b and their derived compounds. In our sprouts, the chlorophyll values were not related to antioxidant capacity and therefore we consider that the ORAC value was not dependent on the contribution of chlorophyll.
