ABSTRACT

1. Objectives To compare the contents of hazardous substances such as crude, washing solution, crude after washing, decoction and remnant. 2. Methods The heavy metal contents of each step were measured by inductively coupled plasma (ICP) spectrometer and mercury analyzer (MA-2). In order to analyze pesticides in Yanggyeoksanhwa-tang we used simultaneous multi- residue analysis of pesticides by GC/ECD, which was followed by GC/MSD analysis to confirm the identity of the detected pesticide in each sample. In addition, the contents of sulfur dioxide (SO2) were performed by Monier-Williams distillation method. 3. Results 1) The mean values of heavy metal contents (mg/kg) for each steps in Yanggeoksanhwa-tang were as follows: crude (Pb; 1.87, As; 1.29, Cd; 0.28 and Hg; N.D.), washing solution (Pb; 1.98, As; 1.13, Cd; 0.10 and Hg; N.D.), crude after washing (Pb; 1.90, As; 1.40, Cd; 0.22 and Hg; N.D.), decoction (Pb; 1.90, As; 1.14, Cd; 0.11 and Hg; N.D.) and remnant (Pb; 2.39, As; 1.29, Cd; 0.25 and Hg; 0.01). 2) Contents (mg/kg) of residual pesticides in crude and decoction were not detected. 3) Contents (mg/kg) of sulfur dioxide (SO2) in crude, crude after washing and remnant exhibited 3.00, 2.00 and 2.00 mg/kg, respectively. However, contents of sulfur dioxide in washing solution and decoction were not detected. 4. Conclusions These results will be used to establish a criterion of heavy metals, residual pesticides and sulfur dioxide of each step in Yanggeoksanhwa-tang.
