[Speciation analysis of arsenic in traditional Chinese medicine].
Some of traditional Chinese medicine (TCM) contain arsenide, such as realgar. The total amount of arsenic in the TCM exceeds the limits according to related regulations. But the roles of arsenic in TCM or its side-effects depend on its species existed in those therapies, not the total amount of arsenic. Therefore, in recent years, the analysis of arsenic in TCM focuses on the species of arsenic. The present paper summarized some methods and techniques in the speciation analysis of arsenic in TCM, in order that optimal methods can be chosen and the roles of arsenic could be evaluated properly.
