Abstract: The extract from Thymus quinpuecostatus was obtained by supercritical carbon dioxide extraction (SFE-CO2) technique. Suitable technological conditions were obtained. The antioxidation effects of the thyme extract were also investigated in this experiment. The results showed that thyme oil has strong antioxidant actions in soybean oil. And it does not bring any bad effects on soybean oil favor.

Key words: Thymus quinpuecostatus, supercritical CO2, antioxidation
