摘要： The present invention provides a novel process for producing an essential oil from a plant material. Concretely, the process produces an essential oil in a short time and by a simple procedure by treating a plant material with supercritical water or subcritical water to liberate essential oil components, which are contained in the plant material, as an ester-free essential oil, and separating and purifying this essential oil.

摘要： The present invention provides a process for producing aromatic compounds or polymers thereof from a plant material in a short period of time and by a simple procedure. Concretely, the process treats the plant material with supercritical water or subcritical water to liberate aromatic compounds, which are contained in the plant material, and/or aromatic compounds, which have been generated upon decomposition of components of the plant material, to the outside of the plant material, and isolates the liberated aromatic compounds to produce aromatic compounds or polymers thereof.
