[Determination of copper, zinc, iron, calcium and magnesium in Pueraria lobata ohwi by FAAS].
The samples of Pueraria lobata ohwi were digested by HNO3 + HClO4. Copper, zinc, iron, calcium and magnesium in pueraria lobata ohwi from Da Bieshan were successfully determined by flame atomic absorption spectrophotometry (FAAS). The results showed that there are rich grand elements, such as Ca and Mg, and profitable elements, such as trace elements Cu, Zn and Fe, in Pueraria lobata ohwi. The content sequence of metal elements is as follows: Copper: leaves > flowers > rattans > roots; Zinc: leaves > flowers > rattans > roots; Iron: roots > rattans > leaves > flowers; Calcium: leaves > roots > flowers > rattans; Magnesium: flowers > roots > leaves > rattans. The results provided useful data for discussing the relationship between the metal elements in Pueraria lobata and hypertension diseases. ohwi and the cure for cerebrovascular diseases.
