Abstract

Eleven metal elements in niuhuang jiangya wan, including sodium, calcium, magnesium, potassium, iron, chromium, manganese, nickel, cadmium, copper and zinc, were determined by flame atomic absorption spectrophotometer. The results showed that there are rich metal elements in niuhuang jiangya wan and provided useful data for discussing the relation between trace elemtnts in niuhuang jiangya wan and cure for high blood pressure.
