[Determination of trace elements in Mongolian medicine Susi-12 curing cholecystitis and gallstone disease by ICP-AES].

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.

[Determination of trace elements in mongolian medicine curing hyperlipidemia disease by ICP-AES].

During the study of the Mongolian medicine, we found that the Mongolian medicine contains great amount and a variety of trace elements needed for human body, but the heavy metals are very little. A method for the determination of Ca, Cu, Zn, Fe, Mg, Mn and Pb in the Mongolian medicine. (1# the morning medicine, 2# the noon medicine and 3# the evening medicine.) by ICP-AES with microwave, digestion was studied. The recoveries of standard addition are in the range of 94.63%-106.40%. The relative standard deviation is < or = 3.41, and detection limit is in the range of < or = 0.009 microg x L(-1). The results show that 1#, 2# and 3# are different kinds of medicine with some difference in the trace elements quantity, but can cure hyperlipidemia disease by their combination.

[Determination of trace elements in Mongolian medicine gardi-13 by ICP-AES with microware digestion].

In the study of Mongolian medicine the authors found that the Mongolian medicine contains large amount trace elements, and is particularly rich in human-body-needed trace elements, but heavy metals are very little. A method for the determination of Ca, Cu, Zn, Fe, Mg, Mn and Pb in Mongolian medicine gardi-13(1#, 2#, 3#) by ICP-AES with microwave digestion was studied. The recoveries of standard addition are in the range of 97.5%-105.5%. The relative standard deviation is < or = 2.90, and the detection limit is smaller than < or = 0.009 microg x L(-1). The results show that 1#, 2# and 3# are some different, and the smell and function have some relation with trace elements. The authors can control the accuracy of preparation dosage and guarantee the quality of products by determining the trace elements.
