摘要：Chinese hickory (Carya cathayensis Sarg.) is one of the most productive woody oil-bearing plant in China. Four different extraction methods were explored and supercritical CO2 was selected as green and non-toxic solvent to extract Chinese kernel oil. Four experiment factors, particles size, extraction time, extraction temperature and extraction pressure, were selected to carry out the single factor experiments. According to the results of orthogonal experiments design, the condition of B3C2A2D2 was the optimum reaction parameters. When the experiments were carried out at the optimum parameters, the yield of Chinese hickory kernel oil was 74.5%. The oil fatty acids profiles were analyzed, the results showed that total unsaturated fatty acids were 93.05%. Among them, oleic acid was 66.5 ± 0.44 as the main component. Saturated fatty acids were 6.92 ± 0.21.
