Determination of the aromatic compounds in plant cuticular waxes using FT-IR spectroscopy

The infrared study of the aromatic components of hops (Humulus lupulus) cuticular wax was performed. HATR FT-IR technique for fresh leaves and their extract analysis was applied. Phenylmethyl myristate, 2-phenylethyl myristate and docosyl benzoate were synthesized and used as reference standards. An absorption band in the range of 709-966 cm-1 indicates the presence of aromatic esters in plant cuticular waxes.
