摘　　要：利用超临界CO2萃取(SCDE)的方法,研究了披针叶黄华萃取工艺,得到总生物碱。探讨了各种影响因素对披针叶黄华萃取得率的影响,通过正交试验确定了SCDE的最佳工艺为:萃取温度45℃、萃取压力20MPa、CO2流量20kg/h、萃取时间80min。在此条件下,总生物碱得率3.12%。The needles of Thermopsis lanceolate R.Br. were extracted with supercritical carbon dioxide to obtain alkaloids. Factors affecting extraction yield were discussed. By orthogonal experiments, the optimum technological conditions were: extraction temperature 45 ℃, pressure 20 MPa, flow rate of carbon dioxide 20 kg/h and extraction time 80 min. The yield of alkaloids was 3.12 %.
