Red ginseng extracts were prepared with various concentrations of ethanol. Extract yields were examined and saponins in the extracts were identified and determined by TLC and HPLC, respectively. Yields of the extracts, $19.7{sim]50.3%$, were the highest in water extract and showed significant decrease with the increase of ethanol concentration used for extraction. Contrary to the extract yields, saponin yields from red ginseng were conspicuously increased with the increase of ethanol concentration and were $3.47{sim}5.13%$ of crude saponins and $1.28{sim}1.93%$ of six major ginsenosides. Saponin contents in the red ginseng extracts were $6.9{sim}24.2%$, of crude saponin and $2.57{sim}9.22%$, of six major ginsenosides.
