摘要
目的:研究无机陶瓷微滤膜分离纯化菊花总黄酮提取液,确定最佳的操作工艺条件。方法:以菊花总黄酮得率和膜通量稳定性为评价指标进行实验,对操作压力、溶液温度和膜的规格进行了优化。结果:最佳工艺条件为无机陶瓷膜孔径0.5μm、溶液温度50℃、操作压力0.30MPa,在此条件下,能使菊花黄酮达到较好地除杂和澄清的效果,菊花总黄酮转移率达90%以上,提取固形物中黄酮含量为19.81%,同时纯化过程稳定。结论:无机陶瓷微滤膜纯化菊花总黄酮提取液工艺简单可靠。
Objective：To separate and purify flavones from chrysanthemum extract solution by inorganic ceramic micro-filtration membrane,the optimal operation condition were researched.Methods：Experiments were designed by chrysanthemum flavones extract rate and flux stability as the evaluating indicator and used three factors to optimize which were operation of pressure,solution temperature and membrane specifications.Results：The optimum technology was inorganic ceramic micro-filtration membrane which pore size was 0.5μm,temperature of extract solution was 50℃ and operation pressure was 0.30MPa.Under these conditions,it could achieve better effect of purification and clarification on chrysanthemum flavonoids,the metastasis rate of chrysanthemum flavonoids was about 90%,the flavonoids content of extracted solids was about 19.81%,and the purification process was stable.Conclusion：The process of membrane technology purifying chrysanthemum flavones was simple and reliable.
