10.22376/ijpbs.2019.10.1.p1-12 Volume 8 Issue 4 2017 (October - December) To assess the antioxidant potential of the new anti-diabetic drug Teneligliptin using DPPH assay. DPPH radical scavenging activity was done using the method of NazninAraandHasanNur (2009)- . Here butylated hydroxy toluene (BHT) was used as the standard compound in this study.The free radical scavenging property of Teneligliptin was found to be 71.87± 0.12% , 65.62± 0.25% , 60.10± 0.33% , %inhibition while that of BHT was found to be 93.91±0.76%, 82.4 ± 0.34 , 74.12± 0.16% , % inhibition at the following concentrations 1000, 750, 500 μg/ ml respectively.From the study, it was found that the study drug teneligliptin has good antioxidant property which could act as a cytoprotective agent in conditions associated with oxidative stress along with its anti-diabetic action. lessThan br / greaterThan Dr.S.SHARANYA , Dr.P.ELANGO , Dr.DARLING CHELLATHAI DAVID Teneligliptin; anti-oxidant assay; DPPH (-2,2-diphenyl-1-picrylhydrazyl) Anti-diabetic drug. 219-223
