Also as shown by 1 H and C NMR spectra there were appearances of distinct peaks indicating prenylation had occurred on the substituted acetophenone ring. The 1 H-NMR of compound (I) showed distinct peaks at 5.30 ppm and 6.27 ppm indicating the presence of allylic protons in the prenylated groups and phenolic protons on the aromatic group. Peaks at 7.49 ppm indicate the aromatic proton. Signals at 1.76 ppm corresponded to signals for terminal methyl groups of the prenyl groups. The proton peaks at 7.36 ppm and 5.28 ppm correspond to aromatic protons on the acetophenone. Peaks at 5.14 ppm and 3.30 ppm indicate the presence of allylic proton and phenolic protons on compound (II) accordingly.
