摘　　要：目的采用半仿生法提取补骨脂中的微量元素,初步探讨半仿生法对微量元素溶出的影响。方法以铜(Cu)、锌(Zn)、锰(Mn)、铁(Fe)元素溶出率为指标,考察3次煎煮液pH值及总煎煮时间对Cu、Zn、Mn、Fe元素溶出的影响。结果第1次煎煮液pH值对Cu、Zn、Mn元素溶出影响较大;第3次煎煮液pH值对Fe元素溶出影响较大,总的煎煮时间对Cu元素的溶出有较大影响,但对其他3种元素影响较小;结论pH值的改变可影响补骨脂中微量元素的溶出。Objective To study impacts of semi-bionic extraction on isolating trace elements from psoraleae fructus. Methods pH values in three decoction and total decoctiug time for Cu,Zn,Mn,Fe extracting were investigated by observing the dissolution rate of Cu,Zn,Mn,Fe. Results The pH value in the first decoction was more effective on dissolution of Cu,Zn, Mn ; and the pH value in the third decoction obviously affected dissolution of Fe. The total decoction time made more influence on dissolution of Cu than Zn,Mn and Fe. Conclusion The change of pH value impacts on dissolution of trace elements from psoraleae fructus.
