The experiments tvere carried out to different temperature which affected growth, yield, proximate and antitumor activity in the Codonopsis lanceolata. Growth of aerial part and subterranean partwere best at 2$0^{\circ}C$ and lower 3$0^{\circ}C$. Components of fat, protein and fiber were best at 3$0^{\circ}C$. Wild C.fonceoforo had higher contents of fat, protein, fiber and ash as compared with cultur'ed C.lanceolataArginin was predominant amino acid in both wild and cultivated C.laceolata No significant differ-ence in the mineral contents was found between the wild root and the cultivated at 30'c inbiotronroom. No minerals difference in the contents was found between the cultivated temperature.The content of elements of inorganic metal differs according to the part. C. lanceolata were subjectedto preliminary antitumer screening test with Sarcoma 180 ascites and screening on V-79 cell. Thisexperiments were conducted in accordance with the total packed cell volume method and cytotoxicity method.

The somatic chromosome numbers were counted to be 2n = 16 of Codonopsis lanceolata. Chromosomes 2 and 7 of Sokrisan and Koheung II has a hetero satellite on short arm. Chromosome 5 of Bakwoonsan showed homo satllite on short arms. Short arms of chromosomes 1 and 5 has homo satellite and short arms of chromosomes 2 and 7 has hetero satellite of Jilin.

In general, stepwise hot steaming process is known to be effective in improving its biological activities; however, not much employed in processing Codonopsis lanceolata due to its hardness. The complex processed C. lanceolata showed highest free radical scavenging acitivity as 45.21%. Total phenol and flavonoid content were of complex processed C. lanceolata higher than conventional extract and alone steaming process. It was showed the lower melanogenesis rate on melanin production test by B16F10 cells as 27.46%. High inhibitory of tyrosinase was also measured as 28.61% by adding steamed Codonopsis lanceolata extracts by high pressure extraction of 1.0 $mg/m{\ell}$. And anti-wrinkle activity were 39.08%. In comparing phenolic acids profiles in the extract, in general higher amounts of polyphenol were obtained possibly by easy release of active components during thermal processing, which results in better antioxidant activities than that of general extract. This findings can also be supported by result that the extract by steaming process showed better activities than the general extraction extract.

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.

A thoredoxin (CTRX) gene was cloned and characterized from a full length cDNA library prepared from taproot of three-year old Codonopsis lanceolata. A CTRX was 666 nucleotides long and has an open reading frame of 372 bp with 124 amino acid residues (pI = 4.92). The deduced amino acid sequence of the CTRX matched to the previously reported plant thioredoxin h genes. The deduced amino acid sequence of CTRX exhibited the similarity of 33-67% among previously registered thioredoxin genes. The expression of CTRX in leaves of Codonopsis lanceolata was increased by wounding and 1 mM $H_2O_2$, but decreased by 0.1 mM cadmium.

The essential oils from the roots of Codonopsis lanceolata and the cultivated callus were analysed and compared by gaschromatography-mass spectrometry. In the experimental study of cell culture, it appeared that 2,4-dichlorophenoxy acetic acid in the culture medium induced higher production of essential oils in the callus than indole acetic acid. The growth of callus was inhibited by illumination of the light. The production of essential oil in cultured cells was increased by the addition of biosynthetic precursors. The essential oils from the roots of Codonopsis lanceolata and the cultured callus showed different compositions. Tetradecanoic acid, 1,1,-dimethoxyl 4-methoxy phenol, 9,12-octadecanoic acid and hexadecanoic acid were identified as main components of the cultured callus oil.

Objectives : A morphological classification among Adenophora triphylla var. japonica, Codonopsis lanceolata, Adenophora remotiflora and Codonopsis pilosula was made through microscopic observation. Method : The slice of the tested material made by paraffin section technique was colored with Safranine Malachite Green contrast methods, and then observed and photographed by olymphus-BHT. Result : 1. Codonopsis pilosula is like a long cone, with amole-like projected parts at the beginning of the roots. 2. Adenophora triphylla var. japonica, Codonopsis lanceolata, Adenophora remotiflora, and Codonopsis pilosula are all similar as following: 1) Cork layers are composed of a few to over 10 subsidiary cells, with individual or a group of stone cells among them. 2) Phloem is wide and has a milk tube. Conclusion : Adenophora triphylla var. japonica, Codonopsis lanceolata, Adenophora remotiflora, and Codonopsis pilosula are all similar and difficult to be distinguished through microscopic observation, so that chemical experiments should be conducted for their identification.

This study was done to investigate the antidiabetic effect of ethanol extract from Codonopsis lanceolata root in Streptozotocin (STZ)-induced diabetic rats. Diabetes was induced by intravenous injection of STZ at a dose 45mg/kg.b.w. dissolved in citrate buffer(pH4.5). The ethanol extract of Codonopsis lanceolata root was orally administrated once a day for 7 days. The contents of serum glucose, triglyceride(TG) and total cholesterol were significantly decreased(p<0.05) in Codonopsis lanceolata root treated group compared to the those of STZ-control group. Also the content of hepatic glycogen and activities of glucose-phosphate dehydrogenase(G-6-PDH) and glucokinase(GK) were significamtly increased(p<0.05). These results indicated that ethanol extract of Codonopsis lanceolata root would have antidiabetic effect in STZ-induced diabetic rats.

The proximate and amino acid compositions of wild and cultivated Codonopsis lanceolata were analyzed. Wild Cadonopsis lanceolata (WCL) had higher contents of fat, protein, fiber and ash as compared with cultivated Codonopsis lanceolata (CCL). Calcium was 1.47 times higher in WCL than CCL. However, contents of iron and phosphorus was 1.45 times and 4.90 times higher in CCL than WCL, respectively. Arginine was the predominant amino acid in both WCL and CCL.
