더덕(Codonopsis lanceolata) 재배지에서 당근뿌리혹선충의 환경친화적 방제법을 구명코자 방제실험을 수행한 결과 당근뿌리혹선충 방제 실험에 사용된 방제제들(Bacillus thuringiensis, Paecilomyces lilacinus, fosthiazate, 한약제 추출물) 중 더덕의 발아를 향상시키는 것을 Bt와 한약제 추출물이었고, 억제시키는 것은 fosthiazated였다. Pot에서 미생물제에 의한 당근뿌리혹선충 밀도억제 효과는 Bt와 Paecilomyces lilacinus 모두 우수하였으나 fosthiazate 보다는 떨어지는 경향이었다. 또한 한약제 추출물도 방제효과가 우수하였다. 포장실험에서도 Paecilomyces lilacinus와 fosthiazate 처리 시 수확량이 가장 많았으며 수확된 더덕의 품질도 가장 우수하였다. 한약제추출물도 무처리에 비하여 더덕의 수량 증대에 효과가 있었고, 뿌리혹선충 감염지에서 키운 더덕을 이식한 것이 비감염지에서 키워 이식한 더덕에 비하여 수량 증가율이 저조하였다.

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

The root of Codonopsis lanceolata has been used in traditional medicine. This study was conducted to confirm the comparative effect of ethanol solvent extraction (CLE) and supercritical carbon dioxide extraction (CLS) of C. lanceolata roots. CLS had higher antioxidant than CLE. For supercritical co-solvent modified carbon dioxide extraction (CLS), it were extracted at 250 bar 50℃ 150 min at a flow rate of ethyl alcohol 3 mL/min for 90min. In addition, CLS inhibited the adipocyte differentiation of 3T3-L1 cells. When treated with the extract at a concentration of 100 ㎍/mL, the Wnt/β-catenin pathway reporter luciferase activity of HEK 293-TOP cells increased approximately by 3-folds compared to that of the untreated control group. Also, the treatment by CLS (50 ㎍/mL) showed a significant increase of involucrin expression. These results indicate that supercritical carbon dioxide extract of C. lanceolatamay serve as a cosmeceutical agent for improving skin barrier function and the treatment of obesity.

The effects of bioactivity, binding polyphenolic contents, DPPH radical scavenging activity, ABTS radical scavenging activity, xanthine oxidase and immune activity on the storage temperature and durations of Codonopsis lanceolata root were evaluated in vitro. The contents of total polyphenol and flavonoid content by storage temperature and storage period was no significant difference according to the storage period, but it was found that the content was higher at lower storage temperature. The DPPH free radical scavenging activity at six different concentrations, 500, 1000, 2500, 5000, 10000 and 20000 mg/L are measured, the scavenging activity according to different storage temperature and storage period showed relatively the higher the activity in the shorter storage period or the lower storage temperature. The ABTS radical scavenging activity did not show a significant difference under various storage temperature and storage period conditions. The xanthine oxidase inhibitory activity of C. lanceolata extract tended to decrease more, depending on the longer storage period or the higher storage temperature. In different storage period and storage temperature conditions, the immune cell growth of C. lanceolata extract promoted a concentration-dependent manner in both human T cell and B cell, and did not show a significant difference. These results of this study suggested that the root of C. lanceolata may assist in the potential biological activities, and can be used as a source of human health products.

Polyploidy has opened a new horizon for selection to sculpt a variety of new gene functions, traits, and lineages. The aim of this study was to investigate the efficacy of the colchicine concentration, temporal changes, and suitable material for inducing effective tetraploid plants of Codonopsis lanceolata. A total of 180 individuals from 16 treatment groups were germinated, and exposed to different concentrations of Colchicine. The plant height of the diploid (18.1 cm) was slightly shorter than that of the tetraploid (13.4 cm). The fresh weight of the main root in the diploid (0.5 g) was 4-fold higher than the tetraploid (2.2 g). The colchicine-treated plant regeneration rate in C. lanceolata was decreased at the elevated concentration of colchicine. A total of 126 individual plants were regenerated in the entire treatment group and tetraploid (2n=4x=32) plants were obtained. In particular, 5 individuals of the tetraploid plant were induced in the 0.05% colchicine for 6h, which is a higher rate (29.4%) than other regenerated plants. As in the seed treatment result, the plant height of the diploid was significantly higher (10.4 cm) than tetraploid. The root length of the tetraploid (10.1 cm) was longer than the diploid, and the root was also thicker. Taken together, the results obtained from the present study may be helpful for the efficient recovery of such polyploid plants through the in vitro application of colchicine, and may improve the productivity and breeding of C. lanceolata.

The Chinese crude drug, 'Man Sam(蔓蔘)', which is derived from the root of Codonopsis plants of the family Campanulaceae, has been used as a tonic. In China, the same crude drug derived from Codonopsis plants, called 'Dang Same(?蔘)', has been used as remedies for anorexia, fatigue, cough, etc. Although Codonopsis roots have been widely used for medicinal purposes in Korea, the botanical origin of the crude drug has never been studied pharmcognostically. To clarify the botanical origin of 'Man Sam', the root morphology and anatomy were examined for the Korean species of Codonopsis species, such as C. lanceolata (Sieb. et Zucc.) Trautv., C. pilosula (Franch.) Nannf. and C. ussuriensis (Rupr. et Maxim.) Hemsl. The study shows that 'Man Sam' is the root of Codonopsis pilosula.
