title: [Study on the determination of metal elements in wild jujube seed decoction by ICP-AES].
abstract: The determination of metal elements in Chinese medicine wild jujube seed decoction was studied by ICP-AES after HNO3-H2O2 digestion. The average recoveries of the method for Ca, Cr, Al, Fe, K, Mg, Mn and Zn in wild jujube seed decoction were found to be 95.5%-106.8%, while RSD (n=5) was found to be 1.7%-3.9% for these metal elements. The method was applied to the analysis of some practical samples and the results obtained were satisfactory.
