摘 要: 建立了用超临界流体从印楝种子中萃取印楝素的方法.用正交试验优化设计选择萃取条件,最佳萃取条件为:温度35℃,压力30MPa,夹带剂用量每克印楝种子干粉1.5 mL甲醇.提取率明显优于溶剂法. The extraction of azadirachtin from neem seeds with supercritical CO_2 fluid was studied. The optimal conditions were obtained with orthogonal arrays, which were 35 ℃, 30 MPa and 1.5 mL methanol per gram neem seed dry powder. The results indicated that the yield of azadirachtin extracted by supercritical CO_2 fluid extraction was higher than that by solvent significantly.
