This study compared the contents of ginseng prosapogenin depending on the extracting conditions of Skin White ginseng(Panax ginseng) to provide basic information for developing Skin White ginseng-based functional foods. Our findings show that the content of crude saponin peaked at 4 hours of extraction(SWG-4) and when extracted at $100^{circ}C$. However, the content of total saponin reached its height at 8 hours of extraction at $100^{circ}C$(SWG-8). On the other hand, the content of prosapogenin reached their heights at 60 hours of extraction(SWG-60), followed by 60 hours of extraction at $100^{circ}C$. And at $100^{circ}C$ the main prosapogenin of the content of Red and Black ginseng ginsenoside $Rg_3$, $Rg_5$ and $Rk_1$ reached their heights at 60 hours of extraction(SWG-60), followed by 60 hours of extraction.
