Objective: To compare the contents and transfer rate of hazardous substances in crude, washing solution, crude after washing, decoction and remnant after boiling.
Methods: The heavy metal contents of each step were measured by inductively coupled plasma mass spectrometer (ICP-MS) and mercury analyzer (MA-2). In order to analyze pesticides in each sample 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.
Results: 1) Contents (mg/kg) of heavy metals in decoction of all herbal medicine prescriptions were not detected. 2) Transfer rates (%) of heavy metals from crude to remnant were As (83.3%), Cd (100.0%), Pb (182.6%) and Hg (100.0%). 3) Contents (mg/kg) of residual pesticides were not detected. 4) Transfer rate (%) of sulfur dioxide (SO2) from crude to remnant was 44.2%.
Conclusion: Our results showed that boiled herbal medicine prescriptions which we take is safe from the hazardous substances.
