The chromosome number was identified and fluorescence in situ hybridization(FISH) mapping of 5S and 45S rDNAs were conducted for C. minima and C. lanceolata in the genus Codonopsis from Jeju island. In this study, we have confirmed that the somatic metaphase chromosome number determined as 2n=2x=16 was the same as the findings from the previous studies. While the conventional staining method makes it rather difficult to distinguish satellite chromosomes due to high degree of variability, FISH analysis produced the exact number and location of 5S and 45S rDNAs. Both species in the genus Codonopsis have a pair of 5S rDNA and their gene loci were observed on chromosome 3. Although two pairs of 45S rDNAs (one on chromosome 1 and the other on chromosome 8) were identified in both species, the 45S rDNA signals on chromosome 8 in C. minima were significantly weaker than those on chromosome 1. In addition, the 45S rDNA signals on chromosome 1 in C. lanceolata showed that the chromosome is non-homologus. In this study, we have determined cytogenetic characteristics of C. minima and C. lanceolata according to their gene replication patterns.

According to previous reports, antioxidant activities of Codonopsis lanceolata could be increased by a steaming process. This study was performed to improve its antioxidant activity and skin whitening activities of C. lanceolata by high pressure and stepwise steaming complex process. The complex processed C. lanceolata showed highest free radical scavenging acitivity as 45.21%, and for phenol and flavonoid contents, complex processed C. lanceolata contained higher than those from conventional extraction process or steaming process alone. The Cytotoxicity of all C. lanceolata extracts also showed low cytotoxicity against human fibroblast cell (CCD-986sk) as 4.49 ~ 10.40%. In whitening activity, high inhibition of tyrosinase activity was estimated as 25.08% by adding the extracts from complex process. We found that whitening and antioxidant activity of complex processed C. lancolata extract was higher than those obtained from conventional extraction and a steaming process because various kinds of antioxidant compounds could be easily released by combined process, compared to one of each process.

Medium composition plays a key role on influencing organogenesis in plant tissue culture. This study was carried out to examine the effects of medium composition on organogenesis in diploid and tetraploid Codonopsis lanceolata and obtain in-vitro mass propagation of superior species of C. lanceolata. Diploid C. lanceolata was found to be declined regarding MS medium composition for each concentration. However, shoot and adventitious root formation were suppressed with higher mineral salt concentration, and active growth of shoot and adventitious root was exhibited as 4.9 cm and 3.2 cm respectively in 1/2 MS medium. While in tetraploid C. lanceolata, it showed 2.9 cm and 3.2 cm respectively in 1/4 MS medium. In the case of sucrose concentration, no consistent decrease was observed for growth of shoot and the adventitious root of diploid both at high and low concentration. The growth of shoot (at 3% concentration) and adventitious root (at 7% concentration) was 2.3 cm and 2.0 cm respectively. Although there was no difference in shoot formation of tetraploid C. lanceolata in all concentrations with the range of 1.7~1.8, there was a slight decrease in shoot growth at high concentration. Results revealed that the adventitious root formation was suppressed at high concentration. The concentration of agar exhibited no significant difference in shoot formation of diploid C. lanceolata at all concentrations. The maximum result of adventitious growth (4.1 cm) was observed at 0.8% concentration. Slight inhibition of shoot formation and root formation of tetraploid C. lanceolata was observed at higher concentration. Shoot formation of diploid C. lanceolata also exhibited inhibition at higher concentration. Shoot formation of diploid C. lanceolata was increased at lower pH and shoot growth was the highest (2.3 cm) at pH 3.8. Adventitious root formation was higher at lower pH. However, both the adventitious root formation and growth exhibited comparatively higher result at pH 5.8. Taken together, the levels of pH had an effect on shoot and root formation in diploid and tetraploid of C. lanceolata

We investigated the changes of volatile flavor components from Codonopsis lanceolata, which were packed in woven polypropylene(WP) film or low density polyethylene(LDPE) film and stored for 15 and 30 days at refrigerated($2{\∼}4^{\circ}C$ ) or room($18{\∼}20^{\circ}C$) temperature. A hundred and sixty seven volatile flavor components in the fresh C. lanceolata were identified by GC/MS analysis. When determining the flavor components from C. lanceolata cultivated on a wild hill and stored at 4 conditions for 30days, six volatile components such as 1-hexadecene, 2,6-dimethyl-2-octanol, 2-methyl-2-dodecanol, $\alpha$-guaiene, $\delta$-cadinene and trans-2-hexen-1-ol were detected as common components of all stored samples, and The types of common flavor components of C. lanceolata were different according to storage conditions. The numbers were 16 from refrigerated, 7 from room temperature stored, and 10 components from WP or LDPE packed conditions, respectively. The total peak area ratio of the major 10 compounds were $52.0{\∼}86.8\%$, and the percentage of trans-2-hexen-1-ol, which was the only common compound among the major 10 components, was the highest as $26.4{\∼}68.1\%$ The major flavor profile, describe by highly trained panel, were green, aldehydic, earthy and camphoreous. As the result from sensory evaluation, the freshness of C. lanceolata was maintained better by controlling storage temperature rather than selection of package materials. The best condition for characteristic flavor of C. lanceolata was packing with LDPE and chilling.

Alzheimer's disease (AD), most common form of dementia is characterized that memory deficit and loss of cognitive function. The Codonopsis lanceolata (C.lanceolata) was treated by high hydrostatic pressure process and fermentation. This study was evaluated cognitive enhancing effect C.lanceolata extract by high hydrostatic pressure process and fermentation and compared with common C.lanceolata extract using Morris water maze and passive avoidance test. And their neuroprotective effect on glutamate induced oxidative stress in HT22 cell was investigated by MTT assay. High hydrostatic pressure process and fermented C.lanceolata extract (HFCE) and common C.lanceolata extract (CCE) (100 and 300 mg/kg) were administered to mice. Results showed HFCE enhanced cognitive function than CCE as shown by decrease in escape latency time. HFCE increased the latency time of the passive avoidance test compared to CCE. Furthermore, HFCE showed significant neuroprotective effect against glutamate cytotoxicity in HT22 cells. These results indicate that high hydrostatic pressure process and fermented more improve spatial cognitive ability of C. laanceolata.

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.
