The extracts prepared from rice bran and rice husk were made by 70 C of distilled water for 2 h in a thermostated water-bath (UMAX, UM-SW 50L). The ratio between sample and extraction medium was 1:10 (w/v). The mixtures were then filtered through
filter paper (Whatman No. 1) and the filtrate used for analyzing antioxidant activity in vitro. All analyses were performed in
triplicate.
