abstract
Sorghum contains high levels of a diverse array of flavonoids, many of which are not typically found in other cereal grains. The high levels of compounds like the stable 3-deoxyanthocyanin pigments, proanthocyanidins, flavones, and flavanones in certain sorghum varieties is especially of interest both from a commercial and health perspective. Evidence suggests that the sorghum flavonoids produce specific health benefits that are not observed for other grains like corn, rice, or wheat. For example, epidemiological and laboratory evidence suggest superior chemoprotective properties of sorghum when compared to other grains. Other evidence indicates that sorghum components elicit anti-inflammatory response and other benefits not seen with other grains in vitro and in vivo. This chapter reviews the chemistry of the major flavonoids in sorghum, their unusual properties, and potential health benefits. 2011 American Chemical Society.
