In order to prepare liqueur of Acanthopanax koreanum, changes in major constituents by soaking below 0.5 cm size dried sample 700 g in 10 l of 15~95% spirit solution for 70 days were investigated. Color b was increased according to lower ethanol concentration and longer soaking periods. Extract was increased gradually with soaking periods, and the content was 0.6~0.7% (w/v) with stem, 1.0~1.5% (w/v) with root. Eleutheroside B and E were extracted rapidly within 20 days of soaking, moreover were increased according to ethanol concentration within 15% to 70%. Acantoic acid was extracted rapidly 2.8~22.6 μg/ml with stem, and 560~1,700 μg/ml with root within 5 to 10 days. For preparation of liqueur of Acanthopanax koreanum, it is necessary to soak more portion of dried root with 60~80% ethanol concentration for 30~50 days, and then to blend after aging for 13 weeks.
