Application of gas-liquid chromatography to the analysis of essential oils. Part IX. Determination of eugenol in oil of cinnamon bark

Abstract

The essential oil obtained from cinnamon leaves has a high content of eugenol whereas the genuine oil from cinnamon bark has a low eugenol content. Determination of the eugenol content of a sample reputed to be cinnamon bark oil provides a method for the detection of adulteration by addition of cinnamon leaf oil. This determination has been carried out by gas-liquid chromatography using a non-polar stationary phase.
