The changes in free sugar composition were investigated with respect to the kinds of dried ginseng for extraction, the various ethanol concentrations used for ginseng extract manufacture and the conditions of heating temperature and time under which the ginseng extract was stored . The results are as follows: 1) The free sugar content of dried ginseng was 6.02-8.02% and the sucrose and maltose content in the free sugar was 70-80%. 2) The free sugar content was 13.82-26.29% in the Sanggunsam (dried ginseng of whole root) extract and it had a tendency to increase with increase in ethanol concentration. In addition, when a higher ethanol concentration was used, the sucrose content was in- creased but the maltose content was decreased. 3) The glucose, sucrose and maltose content in ginseng extract, decreased, in the order, as heating temperature and time were increased. On the other hand the opposite results were neted for xylose and fructose. Keywords Panax ginseng, ginseng extract, Sanggunsam.
