title: [Determination of trace elements in Mongolian medicine Susi-12 curing cholecystitis and gallstone disease by ICP-AES].
abstract: Trace elements in Mongolian medicine Susi-12 for cholecystitis and gallstones were analyzed in order to discuss the relation between Susi-12's drug action and the trace elements. The analysis was carried out using the pressure seal microwave digestion and inductive coupled plasma atomic emission spectrometry (ICP-AES). It was found that the medicine contained great amount of trace elements, especially human-body-needed trace elements, such as Ca, Al, Mg, Fe, Sr, Mn, Zn, Cu etc., whereas heavy metals are very little, e.g. the contents of Pb, Cb, As etc are below the country's limit. The recoveries of standard addition are in the range of 94.63%-106.40%. The relative standard deviation RSD< or =3.35%, and detection limit is < or =0.009 mg x L(-1). It is concluded that Mongolian medicine Susi-12 can effectively control and cure cholecystitis and gallstones, and the effective rate reaches 91.2% to 100%. So the trace elements in Susi-12 must have a close connection with the drug action.
