| Abstract: | The contents of six trace elements in extracts of thirty species of Chinese crude drug using two different extractionmethods were determined by atomic absorption spectrophotometry. The results indicated that the six trace elements were lost invarious degrees in the process of water extraction method and were almost completely lost in the process of water extraction andalcohol precipitation method. |
