Material and Methods: The plant extract (50mg) obtained by soxhlet extraction method was dissolved separately in 50ml of methanol and the resultant solution serially diluted to concentrations 0.5, 0.25, 0.125 and Scavenging activity was tested by 1,1-diphenyl-2-picrylhydrazyl (DPPH) method and the inhibitory effect on lipid peroxidation was examined by the ferric thiocyanate (FTC) and thiobarbituric acid (TBA) methods. The results suggested that the strong antioxidant activity of extracts might be due to the presence of phenolics compounds present in the extract . Halophyte plant (HPs), a salt-resistant flora, has been reported to provide several health benefits, but the knowledge of its cosmeceutical potential is still ambiguous. The antioxidant activity of methanolic extracts from Garcinia atroviridis obtained via maceration showed good results with a minimum EC 50 value of 9.32 and 5.32 g/mL for DPPH and ABTS assay .
