Abstract
The GC pictures were taken to investigate the difference of Samul-tang and Sakunja-tang from their distillate each. For Samul-tang, it's distillate contained many peaks which had been shown very small peaks in the GC picture of the original solution, but the one pick(rt about 7 min.) of the picture didn't been found in the GC picture of the distillate. For Sakunja-tang, it's distillate contained all peaks which had shown in the GC picture of the original solution. After distillation, there was almost no peak in the rest of the solution.
