Growth characteristics and aromatic constituents of wild and domesticated Codonopsis lanceolata grown in different regions were investigated to find the best cultural condition for quality improvement. The results were as followings: Air temperature of wild region was lower to 4~8 and soil temperature was also lower to 3 compared with domesticated region. Soil of wild region had about three times richer organic matter with lower pH. Chromosome number of wild and domestcated species was 2n=16, ovary number was 3, but seed number of wild species was 132 vs domesticated showing 62. Recovery yield of wild species grown wild region had 0.55%, besides that, the wild species grown in domesticated region had 0.34. But the domesticated species in wild and domesticated regions was the same as 0.28. Inorganic element contents of domesticated region showed much higher than that of wild region. Major aromatic constituents were specified in wild Codonopsis lanceolata as dimethyl benzene, 3-ethyl-5-2-(ethylbutyl)-octadecane, benzaldehyde, 14, 14-dimethyl-hexadecanoate, methylhexadecenoate of which was not detected in domesticated species.
