Relationship between the morphological variations and the saponin contents of Panax pseudo-ginseng Wall. (Araliaceae) plants (P.p-g) was investigated by using the pseudo-ginseng plants from thirteen habitats in Nepal-Himalayas and Japan. On the basis of the morphological characters and random amplified polymorphic DNA (RAPD) analysis, these P.p-g were classified into four types, Himalayan (H)-1, H-2, Japanese (J)-1 and J-2. On the phylogenic tree, H group strains and J group strains form distinct separate groups, and H-2 type forms a separate group with a large distance form the other three types. On the other hand, on the basis of the dammarane and oleanane saponin contents, P.p-g were grouped into three chemotypes, H-1, H-2 and J types. These results indicate that RAPD analysis in combination with the saponin content assay might be useful for the classification of P.p-g in different habitats.
