Abstract

This studies were conducted to investigate the effect of extraction and evaporating conditions on the free sugar in ginseng extracts. Raw ginseng roots were extracted with water or various concentration of water-ethanol solutions. Then the extracts were evaporated by boiling or vacuum evaporated at 50 $^{\circ}C$ and 70 $^{\circ}C$. The results are as follows Sucrose and maltose contents were 7.95% and 12.8% in water extracts and 19.96%, 0.34-0.93% in 90% ethanol extracts, respectively. On the otherhand, glucose and fructose contents were not affected by the solvents. Evaporating conditions, such as temperature, were rarely effected to the sugar contents.
