layers of grain and bran were obtained in the study of H u n g and M o r i t a
(2008).
The investigated extracts differed significantly (P < 0.05) in their total
phenolics content that is contributed to the different abilities to inhibit lipid
peroxidation (Fig. 2—4), i.e. to exhibited differences in antioxidative activities
(AOA). Z i e l i n s k i and K o z l o w s k a (2000) have the statistically significant
correlation between antioxidative activities and total phenolics of cereals
and their fractions. A correlation between antioxidative activity and rutin content
or total flavonoids content in buckwheat cultivars has been shown (J i a n g
et al., 2006).
