We report the biological activity of the ethanolic extractions of Suaeda japonica Makino. The layer fraction contains hexane, chloroform, ethyl acetate, butyl alcohol, and H2O and dried the samples. The antioxidant and reducing potential activity as well as the polyphenolic, tannin and flavonoid compounds extracted from Suaeda japonica Makino were evaluated by different assays. The subterranean parts was used for these standardized assays. The maximum antioxidant activity was observed in ethyl acetate. The total phenolic and total flavonoid content were highest with ethyl acetate and the butyl alcohol fraction. High reducing potential was observed in the ethyl acetate fraction. A positive correlation was observed between the antioxidant activity and polyphenolic compounds (total phenolic content and total flavonoid content). Similarly, there was significant correlation between antioxidant activities and reducing potential indicating that the reducers present in the ethyl acetate fraction are major contributors to the antioxidant potential. Thus, the ethyl acetate fraction of this plant could be used for pharmaceutical and functional materials applications.
