| Abstract: | [Objective]To optimize the extracting process of microelements of Astragalus from Ningxia.[Method]The essential micro elements such as Cu,Fe,Zn and Ca from Astragalus in Ningxia was extracted by Microwave assisted extraction(MAE),and their contents were determined by Flame Atomic Absorption Spectrometry(FAAS) method.[Result]Taking water as solvent,the contents of Cu,Zn as measure basis,the best process which were optimized by orthogonal experiments was 1:5.0 of solid-liquid radio,10 min of extraction time,480 W of microwave power;under these conditions,extraction effect of the microelement in Astragalus from Ningxia was good.[Conclusion]These primary research results provided the theoretic basis to understand the quality of Astragalus from Ningxia comprehensively. |
