Studies on Phytochemical Screening and in vitro Antioxidant Activity of Ethyl Acetate Leaf Extract of Justicia gendarussa Burm. F.

摘要

Plant antioxidants have gained significant interest in recent years for their role in preventing the auto corrosion of fats and oils. The present study was aimed to screen the phytochemical constituents such as alkaloids, anthraquinons, cumarins, flavonoids, glycosides, phenols, saponins, steroids and terpenoids from the ethyl acetate leaf extract of J usticia gendarussa and also to assess the antioxidant potential of same extract. Result of present investigation clearly revealed that total phenoliccontent was 34.10士0.79 mg/100 mg GAE and total flavonoid was found to be 15.01±0.30 mg/100 mg QE. In vitro antioxidant activity of J. gendarussa leaf by DPPH assay showed 74.20±0.44%, FRAP assay showed 72.15±0.44% and nitric acid scavenging assay revealed 65.99±1.93%， remarkably hign phenolic content and antioxidant activities were found in the ethyl acetate extract. Further studies, to isolate and identification of bioactive compounds in food and pharmaceutical industries.
