After ultra high pressure treatment, limonene concentration was decreased greatly while myrcene and α-pinene concentrations were not changed significantly and the concentration of limonene was decreased by 75% after high pressure treatment of 500 MPa for 15 min,α-terpineol and carvone concentrations were increased significantly. The aldehydes concentrations were retained well. The ester concentrations were changed under high pressure treatment, but generally their concentrations were not changed remarkably.
