- Abstract
[Objective] To determine the content of mineral elements in traditional Chinese medicine (TCM) Radix Millettiae Speciosae. [Methods] Nitric acid-perchloric acid was adopted for digestion, and flame atomic absorption spectrometry was applied to determine the contents of mineral elements of Ca, Mn, Mg, Fe, Cu and Pb in the traditional Chinese medicine (TCM) Radix Millettiae Speciosae. [Results] In Radix Millettiae Speciosae, the contents of Ca, Mn, Mg, Fe, Cu and Pb were respectively 3 279.05, 2008.30, 381.53, 450.04, 16.36, and 1.96 μg/g. The recovery of standard addition of this method was 96. 99% - 101.38%, and RSD value was less than 2%, so it was with good accuracy and precision. [Conclusions] In Radix Millettiae Speciosae, the contents of Ca, Mn, Mg are high, yet those of Cu and Pb are low. Data obtained in the determination could provide basis for studying the relationship between mineral elements and pharmacological activity of Radix Millettiae Speciosae.
