The parameters of extracting grape seed oil containing proanthocyanidins by supercritical CO2 fluid extraction technique were studied. Using the oil yield and the extraction rate of proanthocyanidins as the targets, the parameters of extraction time, extraction pressure and temperature were optimized by uniform design. The optimum extraction conditions were obtained as follows: extraction pressure 15 MPa, temperature 50 ℃, time 3 h.Under the optimum conditions,the oil yield was (10.92±0.25)% and the extraction rate of proanthocyanidins was (23.4±7.2) mg/100 g. The grape seed oil containing proanthocyanidins could be extracted by supercritical CO2 fluid extraction technique with ethanol co-solvent.
