초록
Korean red ginseng tails was extracted with solutions having various ethanol concentration at the temperature range of 70-100 $^{\circ}C$. Extraction was carried out for 1-5 times of 8 hours at given temperature. The results obtained on physicochemical properties of yields, saponins, sugars, minerals, color and viscosity were analyzed statistically to find the correlation with extracting conditions. A very high positive correlation was found between extraction time and cumulative values of yields of chemical components. Increase in ethanol concentration affected negatively on viscosity, absorbencies and yields of soluble solids and minerals. Some of the properties also showed a high correlation with temperature increase. Equations were also derived from the significant results on correlation analysis.
