['Murraya exotica L., a member of family Rutaceae is rich in biologically active secondary metabolites and also known for its ethnobotanical importance. With this in mind, the plant was chosen and leaves were extracted sequentially to obtain ethanol, hexane, chloroform, ethyl acetate, n-butanol and aqueous fractions. The extract/fractions were evaluated for total phenolic and flavonoid content by spectrophotometric methods. The UHPLC technique was employed for profiling the different polyphenolic compounds present in the extract/fractions. Furthermore, the extract/fractions were analysed for the antioxidant and antimutagenic activities using different in vitro assays.', 'It was observed that, among the different extract/fractions, ethyl acetate fraction exhibited maximum total phenolic content i.e. 119.6\xa0mg of GAE/g whereas chloroform fraction showed maximum total flavonoid content i.e. 323.5\xa0mg of RE/g. Likewise, UHPLC method also showed maximum number as well as amount of polyphenolic compounds in ethyl acetate fraction. It was further analyzed that the same fraction exhibited the maximum radical scavenging activity in all antioxidant assays. In Ames assay, ethyl acetate fraction again showed maximum antimutagenic activity of 97.70\xa0% against the 2-aminofluorene mutagen in TA100 tester strain of Salmonella typhimurium.'] Does delineation of attenuation of oxidative stress and mutagenic stress by Murraya exotica L. leave?
