Dried parts of the two species are difficult to distinguish morphologically, thus Codonopsis radix has been sold instead of Adenophorae radix in herbal medicine market. Therefore, this study was conducted to develop the genetic marker through the examination of the phylogenetic relationships between two Adenophora triphylla(Thunb.) A. DC. var. japonica Hara, two Adenophora radiatifolia Nakai, five Codonopsis lanceolata(Sieb. et Zucc)Trautv. using RAPD analysis. Fifty decarmer oligonucleotide primers were screened for the RAPD analysis, and four primers generated distinct RAPD markers specific to Adenophorae radix and Codonopsis radix. Based on the RAPD patterns, the genetic relationships between three herbal medicine were analyzed by UPGMA method. As a result, Adenophorae radix and Codonopsis radix were classified into two major subgroups on the basis of the genetic similarity coefficient. The specific RAPD patterns generated by the selected primers were reproducible from dried materials. Furthermore, the specific RAPD patterns were produced from the mixture of dried roots of A. triphylla and C. lanceolata. These results prone the usefulness of the RAPD analysis for the discrimination of pure materials from the mixtures of A. triphylla and C. lanceolata.

This experiment was conducted to increase essential oil and aromatic contents on roots of Codonopsis lanceolata Trautv with different shading treatments. Vine length was prolonged by shading treatment compared with non-shading. Fresh root weight in 75% shading treatment was highest with 13g per plant. Crude components such as crude protein, fat and fiber contents decreased, while crude ash increased as shading degree increased. Forty-eight volatile aromatic compounds in the root were identified by GC/MS. Major aromatic compounds were 1-hexanol, cis-3-hexanol, and trans-2-hexanol. In particular, trans-2-hexanol was highest in the 75% shading treatment attaining the 160.32 % area. Conclusively, it was suggested that the 75% shading treatment was to some extent effective to improve the content of essential oil and aromatics in the roots of Codonopsis lanceolata Trautv.

Embryogenic calli of Codonopsis lanceolata were cultured on MS agar medium containing various concentrations of sucrose as a carbon source. Upon transfer to MS basal medium, somatic embryos of cotyledonary stage converted to plantlets. When sucrose was added with greater than 4%, the number of shoots and roots regenerated from somatic embryo increased. However, the growth of shoots and roots was retarded in agar medium with more than 2% sucrose, but promoted in medium with lower concentration of sucrose. Saponin contents of shoots regenerated from somatic embryos, embryogenic calli, non-embryogenic calli, and native roots were determined by HPLC. Saponin contents of native root was variable, depending on regenerant, embryogenic calli, and cotyledonary embryos. The saponin contents of regenerated roots in medium with high sucrose was similar to native roots. Saponins content based on cell differentiation to shoot and root was dramatically decreased. This results could be effectively controlled for the production of useful secondary metabolites.

The experiment was carried out to determine the effects of soil condition on the agronomic characters and aromatic substances in cultivated Codonopsis Lanceolata. An increase of planting densities of Codonopsis Lanceolata. from 1 to 5 plant per pot resulted in the smaller root width, but root yield increased from 109.8g to 286.9g per 1/200pot. The width growth as soil water contents were higher in surplus soil water than that of cultivated deficit soil water. The contents of water, reducing sugar, crude protein and malic acid were higher in cultivated wild than in cultivated upland soil. The higher contents of volatile essential oils as 3-rnethylpentanoic acid and squalene was obtained at the normal soil moisture.

This study aimed to investigate the effect of growth regulators on the formation of the organ in the in vitro propagation of diploid and tetraploid Codonopsis lanceolata, and gain the basic data for in vitro propagation of superior C. lanceolata. In the case of diploid C. lanceolata, the highestshoot formation (3.0) was observed at 0.5 mg·L^-1 addition medium with low IBA concentration. The shoot formation of tetraploid C. lanceolata was suppressed by addition of IBA. In the addition of lAA, the shoot formation of diploid C. lanceolata was slightly higher at 1.0 mg·-L^-1 addition medium than that of control group, whereas tetraploid C. lanceolata showed the highest number (5.4) from control group. In the case of NAA, the shoot formation of diploid and tetra C. lanceolata tended to decrease at higher concentration. In terms of BA addition, the shoot formation of diploid C. lanceolata was increased by the addition of BA, whereaswhile the growth of shoot was decreased by the addition of BA. In the case of tetraploid C. lanceolata, shoot was found to be formed by the addition of low concentration of BA, and the growth of shoot was inhibited with the higher addition concentration of BA. With the addition of kinetin, the shoot formation of diploid C. lanceolata was slightly higher than that of control group, and the formation of adventitious root was highest (5.3) in the control group. In the case of tetraploid C. lanceolata, the shoot formation was similar in all treatment groups, but the formation and growth of adventitious root were significantly lower than that of diploid C. lanceolata. In the case of TDZ addition, the shoot formation of diploid C. lanceolata showed the pronounced results at 5.0 mg·L^-1 addition medium, and the growth of shoot was inhibited by the addition of TDZ. The formation of adventitious root was 5.3 and 4.9 in the control group and 0.1 mg·L^-1 addition medium respectively. The formation of the shoot of tetraploid C. lanceolata showed better results with the higher concentration of TDZ, and the growth was better with the lower concentration of TDZ. The formation and growth of adventitious root were significantly slower than that of diploid C. lanceolata.

The activities of the antioxidative enzymes in the roots of Codonopsis lanceolata have been compared depending on the cultivated environments - wildness, cultivate paddy fields and cultivate dry fields - and the parts of the root. In the Codonopsis lanceolata raised in cultivate paddy fields, the activity of SOD was higher in 2 yrs old than 1 yr old, but the activity in 1 yr old was higher than in 2 yrs old for the plants raised in the cultivate dry fields. The specific activity of SOD in wildness plants 86.069unit/mg protein was the highest among plants studied. The tissue distribution of the SOD activity showed differences depending on the enviroment. The highest activity of SOD was shown in the upper part of the root for the cultivate paddy fields, the loewr parts for the cultivate dry fields and middle parts for the wildness. The specific activity of POD was increased with ages of the plants, and that in the wildness was the highest 68 unit/mg protein among the plants studied. The activity of POD in the parts of the roots was shown as middle>lower>upper. The activity of POD in the middle part of the root, rasied in Soebick province was 85 unit/mg protein. The specific activity of CAT was decreased with ages of the plants. The activities of wildness and cultivate paddy fields was similar, but that in cultivate dry fields was lower than others. The tissue distribution in the parts of the roots was upper>lower>middle. The activity of CAT middle part of rasied in the Sebuck area was 5.359 unit/mg protein. The activities antioxidative in the cells cultured in MSID(Murashige and Skoog +2.4-D 1mg/$\iota$) was followings: 1564 for CAT. 30 for POD and 22200 unit/mg protein for SOD. These figures were lower than that in in vivo.

This study was conducted to evaluate the effect of anti-obesity and antioxidant enzyme activities in vitro by different solvent fractions from the roots of Codonopsis lanceolata. The cytotoxicity of different solvent fractions of C. lanceolata on 3T3-L1 preadipocytes were evaluated using the MTT assay, the rate of cell survival progressively decreased in a dose-dependent manner. Butyl alcohol fraction at $200{\mu}g/mL$ exhibited a pronounced cytotoxic effect (75.73%) on 3T3-L1 cell comparable to that of the hexane fraction (79.82%), methylene chloride fraction (84.02%), ethyl acetate fraction (87.62%) and DW fraction (86.30%) at the same concentration. The Oil Red O solution was used to determine whether different solvent fractions of C. lanceolata induce adipocyte differentiation in 3T3-L1 preadipocytes. Confluent 3T3-L1 cells were treated with $50{\mu}g/mL$ concentration of solvent fraction extracts from C. lanceolata. Inhibitory degree of lipid accumulation against solvent fraction extracts showed a significant level compared with the control. Both lipid accumulation and adipocyte differentiation showed relatively high effect on methyl chloride fraction. The root extract of C. lanceolata had the highest SOD enzyme activity of 84.5% in ethyl acetate partition layer and while water partition layer of diploid showed the lowest SOD enzyme activity of 57.9%. The activity of CAT, APX and POD showed a significantly higher activity in ethyl acetate partition layer compared with the other fraction. These results suggested that the roots of C. lanceolata may assist in the potential biological activity on anti-obesity and antioxidant capacity.

Chemical composition of dried roots of wild and cultivated Codonopsis lanceolata has been investigated. General composition was similar in both Codonopsis lanceolata. Free sugars from the root were fructose, glucose and sucrose. The contents of the sugars were higher in the cultivated than in the wild. Maltose was detected only in the cultivated and its level was 0.05%.. Free amino acids were consisted of 16 amino acids: lysine, histidine, arginine aspartic acid, threonine, serine, glutamic acid. proline, glycine, alanine, valine, methionine, isoleucine, leucine, tyrosine and phenylalanine. No significant difference in the contents was found between the wild root and the cultivated. Free fatty acids were palmitate, linoleate and linolenate, and the contents of those acids were higher in the cultivated root than in the wild. The contents of crude saponin were 1.5% in the wild root and 1.4% in the cultivated, respectively.
