| Abstract: | The extraction of panaxynol and panaxydol from Korean ginseng was found to be optimal at 55°C for the shaking method, 80°C for the soxhlet method, and 65°C for the supercritical extraction method. The amount of extracted panaxydol and panaxynol, and their ratio increased over a period of 12h with the shaking method. The soxhlet method produced an extract with the largest panaxydol/panaxynol ratio. A reduced particle size enhanced extraction, however, the ratio of panaxydol/panaxynol decreased. Swelling in water was found to be detrimental for the extraction of panaxydol and panaxynol. |
