Abstract

To develop a method to determine the contents of trace lements in Whiteflower herba Patriniae with Flame Atomic Absorption Spectrometric(FAAS),which provide a certain amount of scientific evidence in exploring the types of trace elements and the relationship between content and effect.The sample was prepared by via wet digestion and detected trace elements in Whiteflower herba Patriniae with FAAS.The contents of Fe,Mg,Ca in Whiteflower herba Patriniae were 0.811,5.134,39.363 mg/g.The results showed that the recovery of standard addition varied from97.7%-102.8%,the relative standard deviation(n=6) was in the rage of 0.13%-0.62%.All these results prove this procedure is rapid,simple,sensitive and accurate,which can be used to determine trace elements in other chinese herbs.
