Yu, Nutrition and Food Science, University of Maryland, College Park, MD 20742. Whole black peppercorn and ground nutmeg extracts in 50% acetone and 80% methanol were evaluated for their radical-scavenging activities against cation ABTS, DPPH and peroxyl (ORAC) radicals. For each extract, the total phenolic content (TPC) was also determined. The extracts of black peppercorns and nutmeg showed significant radical- scavenging activities and TPC. The 80% methanol extract of nutmeg had the greatest ORAC value of 1188 umoles TE/g and the highest ABTS radical scavenging activity of 191 umoles TE/g on a dry weight basis. These data indicate that black peppercorns and nutmeg may serve as potential dietary sources of antioxidants for disease prevention and health protection.
