The two medicinal plants namely, Moringa oleifera and Tribulus terrestris are well known for their medicinal roles
ethnobotanically. The present work is to understand the presence of phytochemicals in each of them by TLC method
and by GC MS analysis. The antibacterial study was also conducted for both the plants. The TLC profiles show the
presence of terpenoids, steroids, flavonoids and alkaloids in both the plants. It was observed that antibacterial role
of Tribulus terrestris was evident but Moringa flower extract did not show any antibacterial activity. The GC MS
results show the presence of compounds such as Z-10-Tetradecen-1-ol acetate, Lyxitol, 1-O-hexyl-, 2-Butenoic acid,
2-methyl-, 2- (acetyloxy)- 1,1a,2,3,4,6,7,10,11,11adecahydro- 7,10-dihydroxy- 1,1,3,6,9-pentamethyl-4a,7aepoxy5Hcyclopenta[a]cyclopropa[f]cycloundecen-11-yl
[1aR*,2R*,3S*,4aR*,6S*,7S*,7aS*,8E,10R*,11R*(E),11aS*]]- in Moringa flowers whereas molecules such as
2,2,4-Trimethyl-3-pentanol, n-Hexadecanoic acid and Z-1,6-Tridecadiene were present in Tribulus terrestris.
Further work to understand the molecular mechanism of the compound found in the GC MS analysis is needed.
