Four new prenylated acetophenone derivatives, including one acetophenone dimer [acronyrone D (1)] and three acetophenone monomers [acronyrones E-G (2-4)], along with seven known analogues (5-11) were obtained from the leaves of Acronychia pedunculata. Their structures and absolute configurations were established by analysis of HRMS and NMR data, single crystal X-ray diffraction studies and quantum chemical calculations. In addition, the isolates were tested for their anti-proliferative acivity against HCT-116, RKO and SW480 cancer cell lines. Compound 5 exhibited significant anti-proliferative effects on the three cell lines, with IC50 values ranging from 0.24-5.3 μM.
