Four varieties of black and two varieties of red seed coat peanuts of different Chinese origins were examined for their total phenolic content (TPC), total flavonoid content (TFC), condensed tannin content (CTC) and monomeric anthocyanin content (MAC) in whole kernel, seed coat and cotyledon using colorimetric methods. Antioxidant activity of the separated components for each variety was determined utilizing DPPH scavenging capacity and ferric reducing antioxidant power (FRAP) assay. Contribution rates of the separated components were calculated for each parameter. It was observed that in all the six varieties, most of the phytochemicals and antioxidant activities were predominantly contributed by the seed coat followed by the whole kernel and then cotyledon. Boiling led to significant (p < 0.05) losses in the phytochemical content and antioxidant capacity. The average MAC value for the black seed coat was significantly (p < 0.05) higher than that observed for the red seed coat. (C) 2015 Elsevier B.V. All rights reserved.
