Abstract

OBJECTIVE:To detect the contents of five trace elements-chromium(Cr),manganese(Mn),iron(Fe),zinc(Zn),copper(Cu)in Niuhuang Jiedu tablets,and implement monitoring control over their quality.METHODS:The method of high pressure digestion-atomic flame absorption spectrometry was applied to detect the contents of the five trace elements in nine Niuhuang Jiedu Tablet products.RESULTS:There were insignificant differences in the contents of chromium(Cr),manganese(Mn),zinc(Zn),copper(Cu)in the nine Niuhuang Jiedu Tablet products,but highly significant differences in the content of iron(Fe),with the content of iron being far greater than those of other elements.CONCLUSIONS:This method is simple,rapid,accurate and reliable,and is a detection method for normal analysis of Niuhuang Jiedu Tablets.
