Abstract
The extraction efficiencies of panaxynol and panaxydol according to extraction temperature were the highest at $80^{cdot}C$ among 65, 80, $95^{cdot}C$ with soxhlet and increased with shaking method when temperature increased from $25^{cdot}C$ to $45^{cdot}C$. The amounts of panaxynol and panaxydol were determined by gas chromatography. In time dependence of extracted amounts of panaxynol and panaxydol using shaking method, the efficiencies of panaxynol and panaxydol were increased during 12 hour. The effect of water swelling on panaxynol and panaxydol extraction efficiency using soxhlet and shaking methods, the efficiencies of panaxynol and panaxydol were decreased as swelling time was increased.
