Total Phenolic Content and Antioxidant Activity of Cereals

摘要

Cereals are good sources of various antioxidants that can prevent cardiovascular diseases and certain types of cancer. For barley, buckwheat, corn, millet, oat, rice, rye, sorghum and wheat, the total phenolics content of the selected cereals have been summarized in the literature. Based on the available data of 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and 2,2'-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity in the literature, the antioxidant activity of sorghum (not including white sorghum) is higher than the other cereals, rye has the lowest antioxidant activity, and the other cereals are in the medium antioxidant activity group. The total phenolics content and antioxidant activity of cereals are significantly correlated.
