title: [Determination of trace elements in danggui blood-supplementing decoction by ICP-AES].
abstract: The method for the determination of trace elements in danggui blood-supplementing decoction by inductively coupled plasma atomic emission spectrometry(ICP-AES) was presented. The contents and solubility of the trace elements in Angelica sinensis and Radix Astragali of different proportion were compared. The recovery rates of the procedure were between 97. 2% and 115. 6%. The RSDs were between 0. 82% and 5. 56%. When Angelica sinensis: Radix Astragali was 1 : 5, the solubility of trace elements was the highest. The couplng of danggui blood-supplementing decoction was proved reasonable. The method was simple, rapid, precise, convenient and suitable for traditional Chinese medicine.
