Determination of Trace Magnesium in Ginseng by Flame Atomic Absorption Spectrometry

Kaowen Zhou Yanling Ma Feixu Wang(Biochemical Engineering College,Beijing Union University,Beijing 100023,China)  
The determination of trace Mg in ginseng was studied by FAAS.Samples were treated with carbonization,cineration,digestion with mixed acid,and dissolution with HNO3.The liner range of regression equation A=0.0565C+0.0405(r=0.9987)was 0.06~7.0μg.mL-1.The limit of detection of the method was 0.008μg.mL-1,and characteristic concentration was 0.017 p,g.mL-1.The recovery of 5 samples was 97.7~103.2%. The contents of Mg in other Chinese traditional medicine can be determined by the same way.
