This study was carried out to investigate change of ginsenoside contents in red and fresh ginseng according toroot part and age by hydrolysis. Neutral total ginsenoside contents by hydrolysis in 6-year main root and lateralroot were significantly increased than those by non-hydrolysis, as 41.6 and 32.8%, respectively. However, there wasno significant difference in red ginseng. In fresh ginseng, ginsenoside contents of the protopanaxatriol group such as Re, Rf,Rg₁, Rg₂, and Rh₁ were not significantly different, but Rb₁, Rb₂, Rb₃, Rc, and Rd showed significant difference. The increaserate of neutral total ginsenoside content by hydrolysis was higher in epidermis-cortex than stele. Also, the neutraltotal ginsenoside content was fine root>rhizome>lateral root>main root, respectively. While there was no tendencytowards the increase of ginsenoside by hydrolysis with the increase of root age in fine root and rhizome, there was significantdecrease in main root and lateral root.
