| Abstract: | This study was aimed to determine trace elements in Paederia scandens. The nitric acid and perchloric acid (4:1) mixture was applied to digest the sample. And flame atomic absorption spectroscopy (FAAS) was used to determine the content of trace elements (i.e., Fe, Cu, Zn, Mn) in P. scandens. The result showed that the contents of Fe, Cu, Zn, Mn in P. scandens were 493.3, 6.925, 82.33, 66.42 g·g-1, respectively. The element content of each in high-to-low order was Fe > Zn > Mn > Cu. The average recovery rate was 100.4%. It was revealed that this method is simple and accurate. It was concluded that trace elements (i.e., Fe, Cu, Zn, Mn) in P.scandens is rich. It has provided some useful information for the further pharmacological studies of P. scandens. |
