Antimicrobial activity of two a,b-unsaturated carbonyl compounds, aldols were investigated using the agar disc diffusion and poison plate methods. Compounds were synthesized via the aldol route in very good yields and were characterized by ¹H NMR, 13C NMR, DEPT-135 and IR spectroscopy. Both compounds were found to be antimicrobial activity. However, their mode of action was more antifungal than antibacterial activity.
