(E)-1,5-Diphenyl-1-penten-1-one (I) is an aphicidal compound originally isolated from Stellera chamaejasme L.. In order to get the compound I largely, a practical method for preparing I from starting material acetophenone in four steps was proposed. The structure was confirmed by 1H NMR, IR spectra and elemental analysis. The effect of temperature and solvent on Z/E ratio was also studied in this paper. The bioassay result indicated that compound I showed insecticidal activity against Myzus persicae (LC50 178.96 μg/mL).

Key words: Stellera chamaejasme L., (E)-1,5-diphenyl-1-penten-1-one, synthesis, aphicidal activity
