| 摘 要： | 以万寿菊中的黄色素为研究对象,对影响超临界CO2流体萃取万寿菊黄色素的萃取温度、萃取压力和萃取时间分别进行了单因素研究。通过响应面最终确定最佳萃取条件为:萃取温度为60℃,萃取压力为48.6MPa,萃取时间为180min。在此条件下,万寿菊黄色素的最高得率为8.44mg/g,验证试验值为8.41mg/g,与预测值相对误差为0.36%。因此响应面法可以优化超临界萃取万寿菊黄色素工艺条件。

| Abstract: | The yellow pigment of marigold flower is studied in this paper.Based on single factor experiments,the response surface method is applied to optimize extraction conditions.The results show that the optimum conditions for supercritical fluid extraction(SFE) are as following:temperature of extraction 60 ℃,pressure of extraction 48.6 MPa,time of extraction 180 min.Under the optimum conditions,the extraction yield of marigold yellow pigment is 8.44 mg/g.While the validation test value is 8.41 mg/g,and the relative error is 0.36%.Therefore,the response surface method can be applied for optimization the conditions of SFE extraction marigold yellow pigment. |
