Effects of the dietary supplementation of Codonopsis lanceolata root on triglyceride and cholesterol levels in the serum, liver, breast muscle and bile in male Cobb$\times$Cobb chicks were investigated. The chicks (15-42 days old) were fed diets supplemented with 0, 0.25 and 0.5% Codonopsis lanceolata root. No differences were observed in body weight, feed conversion ratio, gall bladder weight or abdominal fat deposition among the control group and the two treatment groups. Liver weights were higher in chicks fed a 0.5% Codonopsis lanceolata diet than in those fed the control diet (p<0.05). However, serum levels of both glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) were not different among the three groups. Broiler chicks fed either 0.25% or 0.5% dietary Codonopsis lanceolata root showed decreased serum levels of triglyceride, total cholesterol and low density lipoprotein cholesterol compared to the control group (p<0.05). Supplementation with either 0.25% or 0.5% dietary Codonopsis lanceolata root decreased the triglyceride and total cholesterol levels in liver and breast muscle compared to the control group (p<0.05). Biliary cholesterol increased by 15% in chicks fed 0.5% dietary Codonopsis lanceolata root, suggesting that the biliary excretion of cholesterol had been elevated by dietary Codonopsis lanceolata root (p<0.05). In conclusion, these results indicate that dietary Codonopsis lanceolata root can decrease triglyceride and cholesterol levels in the serum, liver and breast muscle of broilers.

당근뿌리혹선충(Meloidogyne hapla)이 더덕(Codonopsis lanceolata)ml 생장에 미치는 영향을 구명하기 위하여 pot와 포장에서 실험을 수행하였다. 그 결과 당근뿌리혹선충의 밀도가 증가함에 따라 pot 실험에서는 더덕의 덩굴생장이 60%, 뿌리생장이 45% 억제되었다. 포장 실험에서는 밀도 수준별 생육차이가 뚜렷하지 않았다. 이 결과는 더덕 구당 선충 접종 밀도가 낮아 피해수준에 도달하지 않은 것으로 사료된다.

This study was performed to investigate the growth characteristics and inorganic components of Codonopsis lanceolata regarding regional differences. The plant height of Japanese Codonopsis lanceolata was 373.6 cm, so it's revealed that it has more vigorous growth than Korean won. The flowering time of Korean Codonopsis lanceolata was 2 weeks faster than Japanese one. Total fresh weight of root was 41.0 g and 39.0 g for Korean and Japanese respectively, thus, no significance difference was found. However, regarding fresh weight, Korean one had a more fresh weight (35.4 g) of main root parts, but Japanese one had a more fresh weight (9.6 g) of the lateral root part. Each inorganic component was found more in the aboveground parts, regardless of the region and the content of K was the largest. Regarding the content of macroelements for each part of Codonopsis lanceolata, the content of Na, Mg, P, S, and Ca in Korean Codonopsis lanceolata was found the highest on the leaf, followed by stem and root. In the case of Japanese Codonopsis lanceolata, same result was found on the content of Mg and Ca, however, the highest content of Na and P was found in the stem.

Disease incidence of Codonopsis lanceolata was surveyed at the major cultivating fields in Chonbuk province in 1996 to 1997. The main diseases of Codonopsis lanceolata were ovserved as leaf spot caused by Septoria codonopsis, anthracnose by Glomerella cingulata, brown leaf spot by Cercospora sp., rust by Coleosporium koreanum, powdery mildew by Erysiphe sp., Fusarium wilt caused by Fusarium oxyporum, and white root rot by Sclerotium rolfsii. Anthracnose, leaf spot and brown leaf spot occurred severely on leaves from early July to late August. They were caused early fallen leaves. Fusarium wilt and white root rot occurred severely on stem and below the soil line in late August. They resulted in withering to death or chlorosis and fallen of leaves. Disease incidence of Codonopsis lanceolata was also substantially different in occurrence with a method of cultivation in late growth stage. Fusarium wilt and white root rot were more severe with a method of no support cultivation than those with a method of support cultivation with a stick. Fusarium wilt occurred 48.8% in a method of no support cultivation but 3.1% in a method of support cultivation with a stick. And white root rot occurred 18.9% in a method of no support cultivation but 0.3% in a method of no support cultivation with a stick. Thus, it proved that soil-borne diseases could be controlled support cultivation with a stick.

We have established adventitious root culture systems of Codonopsis lanceolata, Codonopsis pilosula and Codonopsis ussuriensis. Root segments of C. lanceolata were the best explants for induction of adventitious roots and the number of adventitious root for explant was highest on solid medium with $0.5mg/{\ell}$ NAA and produced $18.8{\pm}1.9$ roots per explant. Root segments of C. pilosula were the best explants for induction of adventitious roots and the number of adventitious root for explant was highest on solid medium with $1.0mg/{\ell}$ NAA and produced $8.5{\pm}1.8$ roots per explant. Leaf segments of C. ussuriensis were the best explants for induction of adventitious roots and the number of adventitious root for explant was highest on solid medium with $0.5mg/{\ell}$ NAA and produced $7.8{\pm}0.4$ roots per explant. In liquid culture, the best production of adventitious root (fresh weight) was obtained in 1/2 MS medium with $1.0mg/{\ell}$ NAA. This study demonstrated for the first time to produce adventitious roots in C. pilosula and C. ussuriensis.

Codonopsis lanceolata (Campanulaceae) has been used in traditional medicines, as its roots contain several kinds of 3,28-bidesmosidic triterpenoid saponin with high medicinal values. In this study, we induced hairy root-derived transgenic plants of C. lanceolata and analyzed triterpenoid saponins from the leaf, stem and root. Transgenic plants were regenerated from the hairy roots via somatic embryogenesis. The saponins are lancemaside A, B and E, foetidissimoside A, and aster saponin Hb. Transgenic plants contained richer triterpenoids saponin than wild-type plants. Major saponin lancemaside A was the most abundant saponin in the stem from transgenic-plant, $4.76mg{\cdot}1^{-1}dry$ stem. These results suggest that transgenic plants of C. lanceolata could be used as medicinal materials for the production of triterpene saponins.

A cytosolic ascorbate peroxidase, hydrogen peroxide-scavenging enzyme, was characterized from Codonopsis lanceolata. The cytosolic ascorbate peroxidase cDNA (CAPX) was 983 nucleotides long and possess an open reading frame of 753 bp with 251 amino acids (MW 27.9 kDa) with pI 5.61. The deduced amino acid sequence of CAPX shows high homology to other known cytosolic APXs ($78{\sim}83%$), but the CAPX was clustered independently from compared ten plant APXs. The CAPX gene was highly expressed in leaf and stem tissues, but not in root. When Codonopsis leaves cut using scalpel were soaked in 1 mM hydorgen peroxide, the expression of CAPX gene was suppressed.

Codonopsis lanceolata (Campanulaceae) has been used in traditional medicines, as its roots contain several kinds of triterpenoid saponin with high medicinal values. In this work, we induced transgenic hairy roots of C. lanceolata and analyzed triterpenoid saponins from the hairy roots and hairy root-derived transgenic plants. Hairy roots were obtained from leaf explants by the transformation of Agrobacterium rhizogenes R1000. Transgenic hairy root lines were confirmed by the transcriptional activities of rolA, B, C, and D genes by RT-PCR. Transgenic root lines actively proliferated on hormone-free medium but not in nontransformed roots. Hairy roots contained richer triterpenoids (lancemaside A, foetidissimoside A, and aster saponin Hb) than nontransformed roots. Transgenic plants were regenerated from the hairy roots via somatic embryogenesis. They showed phenotypic alterations such as shortened shoots and an increased number of axillary buds and adventitious roots. The transgenic plants also contained higher triterpenoid levels than wild-type plants. These results suggest that hairy roots and transgenic plants of C. lanceolata could be used as medicinal materials for the production of triterpene saponins.
