OBJECTIVE: To study the chemical constituents of Cornus officinalis extracted by supercritical carbon dioxide fluid extraction (SFE). METHOD: The process was performed at 40 centigrade with pressures of 15 MPa for 2 hours and with CO2 fluid and gas at the flow rate of 22.0 kg x h(-1) and 18.0 kg x h(-1) respectively. The chemical constituents of the SFE extractions were determined by GC-MS. RESULT: The total amount of extractable substances or yields by SFE is 2.42% (mass). 31 Chemical constituents were identified and their relative contents were determined by normalization method of area. CONCLUSION: The major components identified in the extractions are 1,2-benzenedicarboxylic acid, butyl 2-methylpropyl ester, isopropyl myristate etc.
