GC-MS Analysis and Antimicrobial Screening of Non-Polar Fraction of Tribulus Terrestris

Traditionally Tribulus terrestris commonly utilized for the treatment of renal dysfunction. In present study, the phytochemical composition of non-polar fraction of ethanol extract of Tribulus terrestris twigs have been evaluated with the help of GC followed by GC-MS along with its antimicrobial activity. A total of eleven compounds were identified mainly fatty acid and their methyl esters. In order to support the identifications Kovat’s Retention Indices were also calculate of these compounds. The n-hexane fraction did not showed significant antimicrobial activity against several bacterial strains, only Micrococcus luteus was inhibited by one of the non-polar fraction. However, the distinctive chemical composition of T. terrestris twigs indicate its potential as a source of natural antimicrobial compounds.
