Mineral Chinese medicine limonitum is commonly used in Traditional Chinese Medicine (TCM), with the reported efficacy in treatment of chronic diarrhea, hematochezia, uterine bleeding and leucorrhea increase. The processing of TCM is a common practice and usually occurs before most are prescribed. It is usually processed by calcining and vinegar-quenching in traditional ways. However, the main purposes of these processing methods are still unclear. In this study, we determined the contents of 21 kind of inorganic elements in limonitum and their water decoctions under the above two processing methods by means of ICP-AES technique. The results show that the contents and types of elements in the powder and water decoctions of limonitum and its processed samples have significant differences (P < 0.05). We suggest that these differences may play a direct or indirect role in the pharmacological effect as well as adverse effect of limonitum.
