Abstract: Extraction of oil from pine seeds with supercritical CO2 was studied.Effects of extraction pressure, temperature, time and crushed condition of seeds on oil yield were investigated.Suitable extraction conditions were:pressure 30 MPa, temperature 45℃, time 180 min, and seeds were crushed by pressing.

Key words: supercritical CO2, pine-seed oil
