In vitro antioxidant activity of Rubus ellipticus fruits

Various studies have been done to identify antioxidants from plant sources and efforts have been taken to incorporate it in conventional therapy. In our present study, petroleum ether, ethanolic, and aqueous extracts of Rubus ellipticus fruits have been evaluated for in vitro antioxidant activity using DPPH radical scavenging and reducing power assay. BHA was used as a standard antioxidant for DPPH radical scavenging activity. The reducing power assay of extracts was carried out with ascorbic acid as a standard reducing agent. All the analysis was made with the use of UV-Visible spectrophotometer. The results of the both assay showed that all the extracts of R. ellipticus fruits possess significant free radical scavenging and reducing power properties at concentration-dependent manner. Hence, it can be concluded that the R. ellipticus fruits could be pharmaceutically exploited for antioxidant properties.
