The above findings are supported in the other studies of the inhibitory effects of flavonoids on iron-stimulated lipid peroxidation. Quercetin was found to be an inhibitor of iron-stimulated hepatic microsomal lipid peroxidation (/50 = 200 pmol I ) [134]. Flavonoids eriodictyol, luteolin, quercetin, and taxifolin inhibited ascorbate and ferrous ion-stimulated MDA formation and oxidative stress (measured by fluorescence of 2,7,-dichlorodihydro-fluorescein) in cultured retinal cells [135]. It should be mentioned that in recent work Heijnen et al. [136] revised the structure activity relationship for the protective effects of flavonoids against lipid peroxidation. 

The evaluation criteria applied during database development highlighted a lack of acceptable anthocyanin food content literature. Values were often presented as percentage of the total anthocyanin content." " In addition, test samples were frequently gathered from noncommercial sources, such as horticultural research stations.Moreover, analytical procedures often employed spectral pH differential methodology rather than HPLC to estimate anthocyanin content. Consequently, although there is a substantial amount of characterization information with crude estimates of total anthocyanin content (T able 4.8), anthocyanins had to be excluded from the final database. Similarly, the flavanone eriodictyol was also excluded from the final database due to a lack of rigorously analyzed quantitative information.
