摘要
目的:微波提取优选木香有效成分的最佳工艺条件。方法:采用正交试验法,通过高效液相法测定其指标成分木香烃内酯和去氢木香烃内酯,对微波提取木香有效成分的各影响因素进行考察。结果:优选木香提取工艺为微波功率400 W,以60%乙醇4倍量提取4次,每次20 min。结论:表明微波的提取时间短,能耗低,提取效率高,优于常规回流提取方法。
Objective：To optimize the technological conditions for effective compounds of Aucklandia lappa.by microwave-assisted extraction.Method：The microwave extract technology was chosen and optimized by an orthogonal test.The contents of costunolide and dehydrocostuslactone were determined by HPLC.Each influence factor of effective component of A.lappa by the microwave-assisted extraction was observed.Result：The best extraction was obtained with 400 W as the microwave power.Four volume of ethyl alcohol（60%） extracted for four times and each extract last 20 minitues.Conclusion：The microwave extraction technique is bettev than backflow extraction method.with high efficiency and short extraction time.
