The results from the ABTS assay of lipophilic extracts were considerably
higher than the ORAC values for the same extracts
(Table 4). The cultivars harvested in 2010/2011 were significantly
higher (p 6 0.05) than the 2011/2012 harvest. The ORAC values ranged
from 0.04 lmol TE/g DWfor Climax and 1.13 lmol TE/g DWfor
Darrow, but were less than those reported by Prior et al. (2003)
for pine nuts, sorghum bran and strawberries, which varied from
3.0 to 16.0 lmol TE/g DW. The ORAC values did not correlate well
with total carotenoids (0.58). That can be due to the fact that
carotenoids are nott the only compounds with antioxidant activities
in lipophilic extracts. As reported by Pertuzatti et al. (2012)
lipophilic extracts of blueberries have a large amount of
tocopherols.
