In this study, the physicochemical and sensory characteristics of hot water extracts of Codonopsis lanceolata root skin (RS) and root flesh (RF) subjected to different heat treatments were analyzed to determine whether C. lanceolata RS can be used as a tea material. C. lanceolata RS and RF were roasted, hot-air dried (HDS and HDF, respectively), or steamed and hot-air dried (SHDS and SHDF, respectively). The heat-treated samples were extracted with hot water ($90^{\circ}C$) for 90 min. The hot water extracts of RS and RF had lower L-values and higher b-values than the other samples. The RS extracts had significantly higher polyphenol content and DPPH radical scavenging activities than RF samples. In the sensory evaluation, the color acceptability of the teas made from CS, HDS, and SHDS were found to be significantly different from those of the teas made from their respective flesh samples. The results suggest that the hot water extract of the C. lanceolata RS can be utilized as a tea material.

The immunostimulating activities of the hot-water extract from Codonopsis lanceolata were investigated. The proliferation of BSA-primed lymph node cells was enhanced between 2.8- to 11.2-fold compare to control, when cultured with 1 to $25\;{\mu}g/mL$ of C. lanceolata extract. It showed strong immunopotentiating activity than ginseng extract and as remarkable as Bifidobacterium adolescentis M101-4 known as a positive immunostimulator. The proliferation of splenocytes and Peyer's patch cells was enhanced between 4.2- to 13.8-fold and 3.1- to 6.9-fold, respectively, when cultured with 1 to 25 $25\;{\mu}g/mL$ of C. lanceolata extract. It enhanced the production of cytokines such as $TNF-{\alpha}$ and IL-6 in the culture of RAW 264.7 macrophage cells. In the culture of lipopolysaccharide-stimulated RAW 264.7 cells, production of cytokines was as compared to controls. In unstimulated RAW 264.7 cells, both $TNF-{\alpha}$ and IL-6 production were enhanced between 12.6- to 67.8-fold and 2.8- to 10.1-fold, respectively. The hot-water extract from C. lanceolata is expected to be a safe immunopotentiator to maintain the host immunity and develop a physiologically functional food.

Chemical composition of dried roots of wild and cultivated Codonopsis lanceolata has been investigated. General composition was similar in both Codonopsis lanceolata. Free sugars from the root were fructose, glucose and sucrose. The contents of the sugars were higher in the cultivated than in the wild. Maltose was detected only in the cultivated and its level was 0.05%.. Free amino acids were consisted of 16 amino acids: lysine, histidine, arginine aspartic acid, threonine, serine, glutamic acid. proline, glycine, alanine, valine, methionine, isoleucine, leucine, tyrosine and phenylalanine. No significant difference in the contents was found between the wild root and the cultivated. Free fatty acids were palmitate, linoleate and linolenate, and the contents of those acids were higher in the cultivated root than in the wild. The contents of crude saponin were 1.5% in the wild root and 1.4% in the cultivated, respectively.

This study measured the amounts of uronic acid, total sugars, non-cellulosic neutral sugars, phenolic compounds as well as antioxidants activity in cell wall materials (CWM) derived from different parts of deodeok (Codonopsis lanceolata). The values of the uronic acid (UA): neutral sugars (NS) ratio in polymers extracted from the CWM of the flesh and skin were 4 and 6, respectively. The total sugar contents of the flesh and skin were 788.6 and 824.9 ${mu}g/mg$ of CWM, respectively. Galactose and arabinose were the main noncellulosic neutral sugars. The chemical structure of five phenolic compounds from the CWM were analyzed and identified as vanillic acid, p-OH-benzaldehyde, vanillin, ferulic acid, and 8-O-4' diferulic acid by HPLC spectral data. Among them, p-OH-benzaldehyde, vanillin, and 8-O-4' diferulic acid were the first compounds identified from the deodeok. The content of 8-O-4' diferulic acid in the skin CWM was 56.1 ${mu}g/g$ AIR (alcohol insoluble residue). The ethanol-NaOH fractions from CWM had the highest oxygen radical absorbance capacity (ORAC) activities, followed by the AIR fractions and ethanol fractions.

In order to improve cultivation technique of Codonopsis lanceolata, uniconazol and paclobutrazol were treated periodically with foliar application during differentiation of node. Plant height, width and length of leaves decreased as the concentration of uniconazol and paclobutrazol increased independently of application period. Characteristics of subterranean part of all treatment by uniconazol foliar application did not show any significant difference to control, except when treated at the differentiated stage of 3rd node. But, when uniconazol was treated with the concentration of 10, 100mg $liter^1$, respectively at the differentiated stage of 12th node, fresh weight was increased to approximately 64%, 100% of control, respectively. Control and 10mg $liter^1$ treated at the differented stage of 6th node showed antitumor activity by the P388 cytotoxic screening test. Fresh weight of all treatment by paclobutrazol foliar application was not showed signigicant difference to control, except when treated at the differentiateed stage of 3rd node. But, when paclobutrazol was treated with the concentration of 10mg $liter^1$ at the differentiated stage of 12th node, fresh weight was slightly increased of control. All treatment showed slight antitumor activity by the P388 cytotoxic screening test.

This study was conducted to maintain the productivity of forest production and byproducts production of natural forest. Distribution of wild edible herb species and correlations between wild edible herb species and forest-type, and site factors were surveyed on national forest in Changjeon-ni, Pyungchang-gun, Kang-won-do. Ligularia fischeri was distributed mainly on cutting sites or meadow or Quercus mongolica forest, Pimpinella brachycarpa did on broadleaved mixed forest, and Synurus deltoides did cutting sites or meadow. On conifer plantations major wild edible herb species were not distributed. Pimpinella brachycarpa and Ligularia fischera were distributed mainly on the site of wet soil-moisture condition, Codonopsis lanceolata, Saussurea grandifolia and Synurus deltoides were distributed randomly. The distribution of Ligularia fischeri and Pimpinella brachycarpa were significantly different between slope directions, but those of Codonopsis lanceolata, Saussurea grandifolia and Synurus deltoides were not significant. Ligularia fischeri and Pimpinella brachycarpa were distributed more frequently in north directed slope than the other. Highly positive correlations were proved Ligularia fischeri and Pimpinella brachycarpa, Aconitum jaluense and Veratrum patulum; Pimpinella brachycarpa and Smilacina japonica, Aconitum jaluense and Veratrum patulum.

Deoduk (Codonopsis lanceolata) has a complex chemical composition that includes polyphenols, saponins, amino acids, and other unidentified compounds. The contents of tangshenoside and lobetyolin are considered as standard of quality evaluation of Deoduk. In this study, an ultra-performance liquid chromatography (UPLC) method was developed for the quantitative determination of the two marker constituents, tangshenoside and lobetyolin. The methods for determining the standards of quality were validated by measuring their linearity, specificity, limit of detection (LOD), limit of quantification (LOQ), precision, and accuracy using UPLC. Reversed-phase UPLC analysis was conducted quantitatively to identify individual tangshenoside and lobetyolin in Deoduk extracted with 50% (v/v) aqueous ethanol. We used 21 samples to carry out quantitative analysis of tangshenoside and lobetyolin. Based on their dry weights, the levels of tangshenoside and lobetyolin were 0.36~3.54 mg/g, 0.24~1.29 mg/g, respectively. These results will be valuable as basic data for standardization of Korean Deoduk.
