Comparison of Ginsenoside Composition and Contents in Fresh Ginseng Roots Cultivated in Korea, Japan, and China at various Ages

摘要

Cooking basic information for indexing of fresh ginseng roots (Panax ginseng C, A. Meyer) was determined. Ginsenoside contents of various age fresh ginseng roots cultivated in Northeast Asia were quantitatively analyzed by HPLC. Average contents of total saponin and each ginsenoside of 4-year-old fresh ginseng root cultivated in Korea were higher than those cultivated for longer periods (5- and 6-year-old). One-way analysis variance showed average contents of total saponin and each ginsenoside of 4-,5-, and 6-year-old fresh ginseng roots were not statistically significant. Pour-year-old fresh ginseng root cultivated at Geurasan, Korea contained the highest ginsenoside content among samples studied.
