This report investigates the antioxidant properties of R. cordifolia extract for protection against lipid peroxidation and reduced glutathione (GSH) content in rat liver homogenate compared with vitamin E and parabenzoquinone (PBQ). R. cordifolia protects against depletion of glutathione in a dose and time dependent manner, an inverse correlation was observed between reduced glutathione depletion and malondialdehyde (MDA) formation. Interestingly, parabenzoquinone showed a better response than R. cordifolia on cumene hydroperoxide (CHP) induced malon‐dialdehyde (MDA) release but there was no response in the rate of reduced glutathione (GHS) depletion. Thus it appears that R. cordifolia is a potent antiperoxidative and antioxidant. The mechanism of action is different to that of vitamin E and parabenzoquinone (PBQ).
