[Determination of trace elements in several hemostatic medicinal plants and their boiling water extracts]
Abstract:
The experimental results indicate that the amounts of Cu, Zn, Fe and Mn in Rubia cordifolia and Agrimonia pilosa var. japonica are very small in boiling water extracts (only 6%). But after digestion they may rise to 30%. It was found that the amounts of four trace elements decreased with the increase of extracting time, but the ratios of Mn/Zn and Zn/Cu were almost the same.
