[目的]对微波联合大孔树脂提取腊梅花总黄酮的新工艺进行研究。[方法]在不同的提取工艺条件下进行平行试验、正交试验和对比试验。[结果]原料0.500 g的腊梅花粉末,以70%的乙醇溶液作提取剂,提取剂的用量为1∶60(g/ml),微波功率为288 W,在提取时间为450 s下提取次数3为最佳工艺。确定AB-8为腊梅花总黄酮的吸附树脂。其最佳静态吸附工艺条件为:温度30℃,吸附时间3 h;最佳动态解吸工艺条件为:流速2.6 ml/min,上样液pH值4.3,30 ml 70%乙醇洗脱。与溶剂浸提法相比,采用微波法提取腊梅花总黄酮提取时间由20 h缩短为450 s,提取率从79.86%提高到92.23%,而且AB-8分离腊梅花总黄酮分离效果明显,成本低。[结论]微波联合大孔树脂提取腊梅花总黄酮可工业化推广。
