Based on the untreated biofilm formation in urinary tract infections (UTIs), current study was focused on the inhibition of Pseudomonas aeruginosa (P. aeruginosa) biofilm formation using Nerium oleander (N. ole- ander) essential oils. Initially, the LC-MS analysis of antibacterial potential of hydro distillated N. oleander essential oils was detected by LC-MS analysis. Initially, the antibacterial nature of essential oils was detected by agar well diffusion method against biofilm forming P. aeruginosa. Then, the possible anti- bacterial fractions of the essential oils were purified by preparative HPLC, and confirmed by analytical HPLC peaks. Possible anti-bacterial components of the fractions were merged together and confirmed by agar well diffusion method. Consecutively, the and minimum biofilm inhibition concentration exper- iment was proved that the concentration of 200 mg/mL of purified essential oils was very effective against P. aeruginosa biofilm formation. The decrease survival rate of the MTT assay result was also supported the minimum biofilm inhibition concentration result. Finally, all the results were more evident; the HPLC purified N. oleander essential oils as a promising anti-biofilm factor against P. aeruginosa biofilm formation.
