Several in vitro methods have been conducted in order to investigate the antioxidant activities of ethanol extract from Rehmannia glutinosa. Both the total phenolic and flavonoid component were expressed as the equivalent of positive control with the values of 1432.3±16.2 mg TAE/100 g and 97.6±14.1 mg QE/100 g, respectively.
