GC-MS analysis and anti-oxidant activity of bioactive compounds of Simarouba glauca leaf extracts

Abstract

The aim of this study is to analyse the phytochemical composition, anti-oxidant activity, FT-IR and GC-MS analysis of Simarouba glauca leaf extracts. The chloroform extract exhibited highest T.P.C. (139.82 ± 0.06 mg/g GAE) and highest T.F.C. (41.95 ± 0.50 mg/g QE). The GC-MS analysis confirmed the presence of ten compounds in acetone extract and twenty-two compounds in methanol extract. The GC-MS analysis of acetone fraction showed the major peaks such as Glycerine (13.20%), 1,1,1-trichloro-2-methyl-2-propanol (8.92%), Cyclohexanol,2-methyl-5-(1-methylethenyl)- (6.09%), Tetradecane, 2,6,10-trimethyl (7.68%) and Phytol (7.53%). Some of these compounds exhibit anti-oxidant activities. GC-MS analysis of methanol fraction exhibited the presence of following compounds: Undecane (8.52%), 2,3-Trimethylene-4-pyrone (1.79%), cis-Sinapyl alcohol (2.33%) and Umckalin (1.19%). The acetone and methanol fractions exhibited higher percentage of inhibition in DPPH assay. The overall results of this study indicate that the acetone and methanol fractions have been demonstrated to be efficacious against various diseases.
