[Analysis of trace elements and macro elements in 13 anti-anoxic traditional Tibetan medicine].

Thirteen kinds of anti-anoxic Tibetan traditional medicine including Hongjingtianjiaonang, Anshensan, Wuweishiliusan, Zhangsongbaweichenxiangsan, Shiliuweidujuansan, Ershiwuweiyuganziwan, Ershiwuweizhuhuangjiaonang, Shiwuweilongdanwan, Mijueqingliangsan, Qishiweizhenzhuwan, Bawei-chenxiangsan, Liuweidingxiangsan and Qiweiputansan were digested with HNO3-HClO4 mixed acid. Fourteen trace elements and macro elements in the 13 kinds of anti-anoxic Tibetan traditional medicine, such as silver, aluminium, cadmium, cobalt, chromium, copper, ferrum, hydrargyrum, magnesium, manganese, nickel, lead, stannum and zinc were determined by flame atomic absorption spectrophotometry (FAAS). The results showed that there were comparatively rich trace elements and macro elements in kinds of anti-anoxic Tibetan traditional Medicine. The 13 Anti-anoxic Tibetan traditional medicine contains higher amount of ferrum, magnesium, copper, chromium, zinc and manganese than other elements. This provided useful data for discussing the relationship between trace elements and macro elements and anti-anoxic activities in Tibetan traditional medicine.
