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.
