Dehydrins (DHNs) compose a family of intrinsically unstructured proteins that have high water solubility and accumulate during late seed development at low temperature or in water-deficit conditions. They are believed to play a protective role in freezing and drought-tolerance in plants. A full-length cDNA encoding DHN (designated as ClDhn) was isolated from an oriental medicinal plant Codonopsis lanceolata, which has been used widely in Asia for its anticancer and anti-inflammatory properties. The full-length cDNA of ClDhn was 813 bp and contained a 477 bp open reading frame (ORF) encoding a polypeptide of 159 amino acids. Deduced ClDhn protein had high similarities with other plant DHNs. RT-PCR analysis showed that different abiotic stresses such as salt, wounding, chilling and light, triggered a significant induction of ClDhn at different time points within 4-48 hrs post-treatment. This study revealed that ClDhn assisted C. lanceolata in becoming resistant to dehydration.

This study was to investigate the improvement of immune activities of the extracts from Codonopsis lanceolata by stepwise steaming process and high pressure process. The phenol contents was $8.742{\mu}g/mg$ which was higher than that from conventional extraction using 70% ethyl alcohol at $80^{\circ}C$ for 24 hours. All of extracts at a concentration of $1.0mg/m{\ell}$ showed relatively low cytotoxicity on human normal kidney cell (HEK293) in range of 16 19%. The immune B and T cell growth was improved by extracts using the steamed and high pressure precess of C. lanceolata up to $180{\times}10^4cells/m{\ell}$ and $96{\times}10^4cells/m{\ell}$, respectively. The extract prepared also greatly increased the secretion of both IL-6 and TNF-${\alpha}$ from the stepwise steamed and high pressure process. This results can conclude that stepwise steamed and high pressure process effectively released active biomaterials which could important role in enhancing immune activity in the body.

한국과 중국 동북부 지역에서 수집한 16종의 더덕으로부터 genomic DNA를 추출한 후, Bioneer사로부터 구입한 random primer(10-mer)를 이용하여 PCR을 수행하였다. 총 49종의 primer를 스크린 한 결과 재현성이 있으면서 polymorphism을 보이는 20개의 primer를 선발하였다. 선발한 primer로부터 PCR에 의해 증폭된 DNA의 크기는 125 bp에서 2.0 kb 내외였으며, 총 148개의 band가 관찰되어 평균 band 수는 7.4개였다. 이들 중에서 polymorphism을 보이는 band의 수는 73개이었으며 (49.3%), polymorphism은 각 primer별로 $1{\sim}9$개로써 다양하였다. 16개 수집종의 유사계수 범위는 0.682에서 0.959로써 유전적 유연정도는 크지 않았다. UPGMA 분석에 의한 수집종들의 유연관계를 dendrogram으로 나타낸 바, 수집종들간의 유전적 거리는 $0.133{\sim}0.400$이었으며, 국내 수집종과 중국 수집종간에는 확실하게 두 그룹으로 분류되었고, 유전적 거리는 약 0.281이었으며, 이들은 모두 지역적인 차이를 보였다. 한편, 중국의 '통화현(通化縣)'과 '류하현(柳河縣)' 수집종이 다른 지역의 수집종보다 유전적 거리가 가장 크게 나타났다.

Field performance and morphological characterization was conducted on seven transgenic lines of Codonopsis lanceolata expressing ${\gamma}-TMT$ gene. The shoots were obtained from leaf explants after co-cultivation with Agrobacterium tume-faciens strain LBA 4404 harboring a binary vector pYBI 121 that carried genes encoding ${\gamma}-Tocopherol$ methyltransferase gene (${\gamma}-TMT$) and a neomycin phosphotransferase II gene (npt II) for kanamycin resistance. The transgenic plants were transferred to a green house for acclimation. Integration of T-DNA into the $T_0\;and\;T_1$ generation of transgenic Codonopsis lanceolata genome was confirmed by the polymerase chain reaction and southern blot analysis. The progenies of transgenic plants showed phenotypic differences within the different lines and with relative to control plants. When grown in field, the transgenic plants in general exhibited increased fertility, significant improvement in the shoot weight, root weight, shoot height and rachis length with relation to the control plants. However, all seven independently derived transgenic lines produced normal flower with respect to its shape, size, color and seeds number at its maturity. Indicating that the addition of a selectable marker gene in the plant genome does not effect on seed germination and agronomic performance of transgenic Codonopsis lanceolata. $T_1$ progenies of these plants were obtained and evaluated together with control plant in a field experiment. Overall, the agronomic performance of $T_1$ progenies of transgenic Codonopsis lanceolata showed superior to that of the seed derived non-transgenic plant. In this study, we report on the morphological variation and agronomic performance of transgenic Codonopsis lanceolata developed by Agrobacterium transformation.

더덕의 휘발성 향기성분은 신선더덕의 경우 총 167 종이 확인되었는데 이는 타 연구결과에 비해 상당히 많은 편이었으며, 동일 더덕이라도 저장조건에 따라 종류 및 조성비율에서 매우 큰 차이를 보였다. 조성 비율이 큰 10개의 성분들이 차지하는 비율은 58%였다. 일반재배 더덕을 4가지 조건으로 15일 혹은 30일간 저장하면서 분석한 휘발성 향기성분들 중 1-hexadecene, 2,6-dimethyl-2-octanol, 2-methyl-2-dodecanol, ${\alpha}$-cedrene, ${\beta}$-selinene, farnesane, isoledene등 7종이 모든 저장조건에서 확인되었다. 그러나 각 저장조건에서 나타나는 10개의 중요 향기 성분들을 비교한 결과 모든 저장조건 및 저장기일에서 공통적으로 나타난 성분은 없었으며, trans-2-hexen-1-ol이 $19.8%{\sim}56.0%$, 마대포장 후 실온저장 더덕을 제외한 1-hexanol이 $51.9%{\sim}71.1%$를 차지하는 주요 성분이었다. 마대포장 실온저장 더덕의 경우에는 cyclohexanol이 36.4%, trans-2-hexen-1-ol이 19.8%를 차지하였고, 2-hexenal이 12.7%로 높게 나타났다. 또한 모든 저장조건에서 확인되었던 1-hexadecene, 2,6-dimethyl-2-octanol, 2-methyl-2-dodecanol, ${\beta}$-selinene, farnesane, isoledene들은 조성비율이 매우 낮거나 순위에 포함되지 못하는 것들이 대부분이었다. 더덕 향기성분에 대한 관능평가로 더덕의 품질을 판단한다면 항균포장 냉장저장 더덕이 모든 향취가 높았으며, 그 다음이 마대포장 냉장저장, 항균포장 실온저장, 마대포장 실온저장 순으로 향취가 감소하였다. 이는 포장재의 차이보다는 저온보관 여부가 주요 변인으로 작용한다고 할 수 있다. 결론적으로 더덕 고유의 향취에 대한 관능평가를 통해 저장더덕의 상품가치를 판단할 수 있는 기준이 마련될 수 있을 것으로 기대된다.

Codonopsis lanceolata L. (Campanulaceae) has long been used in traditional Korean medicine to treat bronchitis, cough, and inflammatory diseases, however, the efficacy of anti-tumor activities remains to be defined. In this study the effects of Codonopsis lanceolata (C. lanceolata) on proliferation, migration and adhesion in lung (A549, H1299) and ovarian cancer (SKOV-3) cells were investigated. To assess and compare the pharmacological effects and production places of C. lanceolata, the ethanolic extracts of C. lanceolata from different places in Korea (Hongseong, Yecheon, Yeongwol, Yanggu, Gangjin, and Hoengseong) were prepared. The extract from Hoengseong county did have only marginal anti-proliferative activity in all the cell lines tested, however, other extracts had little or no effect on cell proliferation. The extracts from Hongseong, Gangjin or Hoengseong county had partial anti-migratory activity in lung cancer cells, but not in ovarian cancer cells. In addition, the extract from Hoengseong county had partial anti-adhesive activity in ovarian cancer cells, however, other extracts did not affect cell adhesion in both lung and ovarian cancer cells. Taken together, these findings provide the first description of anti-tumor efficacy of C. lanceolata from different production places in Korea, and suggest that C. lanceolata from Hoengseong county may have therapeutic potential in lung and ovarian cancers.
