It order to extract the soluble organic substances of Korean ginseng effectively, the ginseng extract have been made by using amylase. The investigation on the optimum condition of enzyme reaction was carried out, and the amounts of gained extract and its saponin pattern were compared among the ethanol extract, water extract and enzyme extract. The results obtained are summerized as follows. 1. The gaining ratio or ginseng extract was the highest value when the raw ginseng and dried ginseng were extracted in the concentration of 7.5% and 5% with 0.3%∼0.6% enzyme for 25 hour. 2. The amounts of ethanol extract, water extract and enzyme extract were 9.14%, 17.23% and 23.73% in case of raw ginseng and 64.09%, 72.52% and 74.36% in case of dried ginseng, respectively. The amount of enzyme extract was increased as much as 6∼14% in case of raw ginseng, and 2∼10% in case of dried ginseng compared with that of ethanol and water extract. 3. The absolute content of saponin was nearly constant in spite of the different extraction method and all of the ginseng saponin pattern of thin-layer chromatograms were almost same.
