| 摘要 | Supercritical CO2 extraction (SC-CO2) of fenugreek (Trigonella foenum-graecum L.) seed oil and its chemical composition and antioxidant activity were investigated. A central composite design combined with response surface methodology was used to study extraction conditions including pressure, temperature, and time. The optimum extraction conditions were 28.5 MPa extraction pressure, 41 A degrees C extraction temperature, and 118 min extraction time, where 3.78 % yield was predicted. Fenugreek seed oil extracted under optimum conditions by SC-CO2 was mainly composed of 28.3 % C18:3, 33.45 % C18:2, 9.89 % C16, 8.1 % C18:1, 3.7 % C18, 0.71 % C20, and 0.61 % C22. The fenugreek oil was rich in unsaturated fatty acids (nearly 70 % of the total fatty acids), and polyunsaturated fatty acids accounted for 61.42 % (mass percentage) of the total amount. The 2,2-diphenyl-1-picrylhydrazyl radical-scavenging activity increased from 12.5 to 88.4 % when the concentration was increased from 1 to 12 mg/ml. The reducing power of the seed oil was concentration-dependent. The antioxidant activity of the supercritical fluid extraction extract was superior to those obtained by Soxhlet extraction.; Supercritical CO2 extraction (SC-CO2) of fenugreek (Trigonella foenum-graecum L.) seed oil and its chemical composition and antioxidant activity were investigated.
