With Eucommia ulmoides seed as the raw material and No. 4 solvent as extractant, the subcrit-ical extraction technology of Eucommia ulmoides seed oil was optimized by single factor experiment and orthogonal experiment. The effects of ratio of material to liquid, extraction temperature, extraction time, extraction pressure and extraction times on residual oil of Eucommia ulmoides seed meal were mainly stud-ied, and the fatty acid composition of Eucommia ulmoides seed oil was analyzed by GC. The results showed that the optimal subcritical extraction conditions of Eucommia ulmoides seed oil were obtained as follows:ratio of material to liquid 1∶5, extraction temperature 35℃, extraction time 1. 0 h, extraction pressure 0. 5 MPa and extraction times three. Under these conditions, the residual oil in Eucommia ul-moides seed meal was 0. 85%. Linolenic acid, linoleic acid, oleic acid, palmitic acid and stearic acid were the main fatty acids in Eucommia ulmoides seed oil,and the content of unsaturated fatty acids was higher than 90%.
