Trace element analysis and in vitro bioactivity of Parkia roxburghii and Rhus semialata extracts

A study on the fruit of Parkia roxburghii and Rhus semialata, specifically found in Nagaland, is being done in this work which includes its phytochemical screening, trace element determination, anti-bacterial and antioxidant studies. Acetone and Ethanol were used for the extraction purpose. Furthermore, in vitro antioxidant studies for determining its free radical scavenging activity were carried out through the DPPH (2,2-diphenyl-1-picrylhydrazyl) and FRAP (ferric reducing antioxidant power) assay as compared with the reference standards Trolox and Ascorbic acid. The extracts were also evaluated for their anti-bacterial activity against four strains of bacteria and to further quantify the anti-bacterial studies, the MIC (Minimum Inhibitory Concentration) of both the samples were carried out by means of two-fold serial broth dilution method.
