| 中文摘要 | 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. |
