다국어 초록 (Multilingual Abstract)

In order to establish the utilization method for the upperground part of Korean ginseng, the contents of dammarane aglycones as function of glycosides in 80% ethanol extracts were analyzed from main roots, leaves and petioles of Korean ginseng grown for 3~4 years. An approach for the assay of sapogenin contents in the part of main roots, leaves and petiles was performed by combination of preparative thin layer chromatographic procedure and vanillin-H2S04 colour reaction. The results obtained were as follows :
1. The differences by their grown ages in the contents of dammarane glycosides, in the ratio of panaxadiol to panaxatriol contents, and in the amounts of 80% ethanol extract of the parts of main roots, leaves and petioles were not sinificant.
2. Differences due to the parts were highly significant in all parameters mentioned, shown following results: main roots: 80% ethanol extract, 21.8-22. 9%. the ratio of aglycone composition, 0.949~1.041, dammarane glycoside(as diglucoside bases) 1.623~l.785, leaves: 80% ethanol extract, 34.87.~36.99%, dammarane glycoside, 12.123~13.009, the ratio of aglycone composition. 0.347~0.360, petioles; 80% ethanol extract, 23.23~23.85%, dammarane glycoside, 1.632~l.670. the ratio of aglycone composition, 0.388~o.446.
