and ground rice husk were not responsible for the antioxidant capacity of the samples as determined by the DPPH radical scavenging activity methods and the FRAP assay. Our result was also in agreement with Yu et al. (2002) and Othman, Ismail, Ghani, and Adenan (2007), who found no correlation between scavenging activity and TPC. In contrast, a study by Kubola and Siriamornpun (2008) found correlations between TPC and antioxidant activity as determined by DPPH and FRAP assay in bitter gourd fractions.
