[Determination of constant and trace elements in Ranunculus ternatus thunb by ICP-AES].

The determination of twenty one kinds of constant and trace elements in Chinese herb Ranunculus ternatus thunb was performed by ICP-AES. The results show that K, Fe, Ca, Cr, Mg, Mn, Zn, Co, Cu, Ni, Se and Sr are relatively rich in Ranunculus ternatus and the content of Pb, Cd and As are very low. The ratio of the content of Zn to that of Cu is about 3, which is consistent with the relative content level of Zn and Cu contained in many anticancer Chinese traditional plants.
