Introduction: Our plant under research, Cymbopogon citratus, commonly referred to as lemon grass and a member of the family fabaceae, is one of those potential medicinal plants. It is known as a medicinal plant and is significant in various uses, particularly pharmaceutical usage due to the presence of the active compounds represented by terpens, phenols, alkaloids, etc. Our plant under study is one of these significant medicinal plants. Objective: In this work, lemongrass was harvested from the desert of the Anbar Region and then extracted using a Clevenger device to produce oil. To identify the phytoconstituents found in the Cymbopogon citratus plant, this study was done. Materials and Methods:The sample was identified by GC-Mass, which indicated the presence of 2-Methyl-Z, 13octadecadienol with percentage 39.86%. Alkaloids, phenols, tannins, and flavonoids were also present, however cardiac glycosides and saponins were not. Results: We isolated certain pure phytopharmaceuticals, which may then be employed as a lead molecule to create a new drug with potent therapeutic effects. The antibacterial activity of lemon grass oil on microorganisms has been investigated utilising the well diffusion method to battle pathogenic bacteria and zone of inhibition of growth with widths of 22 mm. Conclusion: Using the well diffusion method, the antibacterial activity of lemongrass oil on microorganisms has been investigated in order to battle pathogenic bacteria and zones of inhibition of growth with diameters of 22 mm.

The investigation of inhibitory effect of the alcoholic extract of Ocimum basilicum on the growth of Staph. aureus that was isolated from the skin infected in vitro have been studied. Ocimum basilicum was isolated using 95% ethanol. Out of which the percentage of extraction of 45% of weight of dried powder was prepared in ascending gradient concentrations of the alcoholic extract (10-100 mg/ml) and the effective one was selected by agar diffusion method using Staphylococcus aureus. The diameters of the inhibition zones of the bacterial growth were increased parallel with the concentrations of the alcoholic extract concentrations. Low efficiency detected post using 10-20mg/ml concentrations, medium efficiency post using 40-60 mg / ml, whereas concentrations of 80-100 mg/ ml were highly effective and influential against growth of the Staphylococcus aureus.
