Relative area ratios used to compare Mn with Md. The assignment for the proton resonance at 1.26 ppm is uncertain and has been assigned to methylene protons associated with short-chain esters. The area of this resonance was divided by the area of the CH₂ resonance in (A) and the area of the wax ester resonance in (C). The resonance at 5.2 ppm has been assigned to terpenoid protons in the ═CH─ moiety. The area of this resonance was divided by the area of the CH₂ resonance in (B) and the area of the wax ester resonance in (D).
