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.

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.

Proximate compositions of the roots of cultured and wild Codonopsis lanceolata were examined as tile basic reasearch for the study of their source of processed foods.No significant difference in the contents was found between the wild root and thecultivated at 3$0^{\circ}C$ in biotronroom. In view of the results to have measured mineralswhich is included in 14 sorts of Codonopsis lanceolata and surveyed their distribution.12 kinds of minerals including T1, Co, Ge, Sm, Mo, Sc, Be, Cd, As, Ga, Bi, ph are ne-vel or little included in almost source. Other twenty-one sorts of minerals (Ni, Se,Ba, Sb, Si, Ti, B, Li, Ifs, Ca, Sr, Mn, Fe, Cu, Zn, p, Al, Na, V, Cr, K) are more or less in-cluded in all source and Ca, Mg, p, K, and Fe are metals that are included in large qu-entities in comparison with others. No minerals difference in the contents was foundbetween the cultivated temperature. The content of elements of inorganic metal differsaccording to the part of C. lanceolata.

Alzheimer's disease is progressive neurodegenerative disorder by the loss of memory and learning abilities. Codonopsis lanceolata (C. lanceolata) is traditional medicinal plant used for the treatment of inflammatory diseases. The aim of study was to evaluate the effect of steamed C. lanceolata on scopolamine-induced memory impairment in the Morris water maze test and passive avoidance test. In addition, this study investigated the neuroprotective effects of steamed C. lanceolata on glutamate-induced cell death in HT22 cells using MTT assay. The results showed that steamed C. lanceolata (500 mg/kg body weight, p.o.) reversed spatial memory impairment by scopolamine in Morris water maze test and passive avoidance test. Steamed C. lanceolata attenuated memory impairment by scopolamine compared with common C. lanceolata. In addition, administration of steamed C. lanceolata significantly also reduced cell death. We suggest that steaming process more improve cognitive enhancing and neuroprotective effect of C. lanceolata than common C. lanceolata.

Dried parts of the two species are difficult to distinguish morphologically, thus Codonopsis radix has been sold instead of Adenophorae radix in herbal medicine market. Therefore, this study was conducted to develop the genetic marker through the examination of the phylogenetic relationships between two Adenophora triphylla(Thunb.) A. DC. var. japonica Hara, two Adenophora radiatifolia Nakai, five Codonopsis lanceolata(Sieb. et Zucc)Trautv. using RAPD analysis. Fifty decarmer oligonucleotide primers were screened for the RAPD analysis, and four primers generated distinct RAPD markers specific to Adenophorae radix and Codonopsis radix. Based on the RAPD patterns, the genetic relationships between three herbal medicine were analyzed by UPGMA method. As a result, Adenophorae radix and Codonopsis radix were classified into two major subgroups on the basis of the genetic similarity coefficient. The specific RAPD patterns generated by the selected primers were reproducible from dried materials. Furthermore, the specific RAPD patterns were produced from the mixture of dried roots of A. triphylla and C. lanceolata. These results prone the usefulness of the RAPD analysis for the discrimination of pure materials from the mixtures of A. triphylla and C. lanceolata.

The objectives of this study were to compare the antioxidant activities by high pressure extraction of Codonopsis lanceolata from different cultivation areas; Hoeng-sung, Jeju island, and China. Total phenolic acid contents of Hoeng-sung, Jeju, China were estimated as 732.11, 640.25, and 584.85 mg QUR/100 g DW, respectively. The flavonoids contents of Hoeng-sung, Jeju, China were measured as 80.37, 76.46, and 74.55 mg QUR/100g DW, respectively. Generally, contents of phenolic acid and flavonoids, HPE was higher than conventional extraction process. Hoeng-sung Codonopsis lanceolata showed 64.33% of DPPH radical scavenging activity (EDA, %) in 3.2 mg/$m{\ell}$ of Hoeng-sung Codonopsis lanceolata. The reducing power of Hoeng-sung cultivation area Codonopsis lanceolata also showed the high activity as 3.15. In generally, antioxidant activities of Codonopsis lanceolata were increased by high pressure extraction process. Based on these results, higher contents of flavonoids and total polyphenols were found extracted by high pressure extraction of Codonopsis lanceolata grow in Hoeng-sung area than others.

Codonopsis lanceolata (C. lanceolata) has been widely used in East Asia as a traditional medicine to treat various diseases such as bronchitis, convulsions, cough, obesity, and hepatitis. C. lanceolata belonging to Campanulaceae contains bioactive compounds such as polyphenols, saponins, and steroids. However, despite the pharmacological significance of C. lanceolata, the genetic information of this plant is limited and there are few studies of its transcriptome. In this study, we constructed a unigene set of C. lanceolata using Pac-Bio sequencing. Furthermore, the reads generated from Pac-bio and Illumina sequencing were mixed and assembled using rnaSPAdes. All genes involved in the triterpenoid pathway, a major bioactive compounds of C. lanceolata, were searched from the two unigene sets and the expression profiles of these genes were analyzed. The results showed that lupeol, beta-amyrin, and dammarenediol synthesis genes were activated in the leaves and roots of C. lanceolata. In particular, the expression of genes related to lupeol synthesis was relatively high, suggesting that the main triterpenoid of C. lanceolata is lupeol. Transcriptome studies related to lupeol synthesis in C. lanceolata have been rarely reported. Lupeol has been reported to have pharmacological effects such as anti-inflammatory, anti-cancer, and anti-bacterial. This study suggests the importance of C. lanceolata as a lupeol producing plant.

This study was conducted to select Codonopsis lanceolata seed's new pelleting particulate materials and adhesives. Different adhesives (Polyvinyl alcohol (PVA), Carboxymethyl cellulose (CMC), Polyvinyl pyrrolidone (PVP), Xanthan gum (XG), Arabic gum (AG)) and particulate materials (Illite, Diatomite, Pyrophyllite + Illite + Diatomite (PID), Pyrophyllite + Illite + Talc (PIT), Bentonite + Talc (BT)) were tested for seed pelleting. PID for Codonopsis lanceolata seed pelleting appeared to be the best particulate material. Among the pelleting adhesives, PVP was the best adhesive for seed pelleting, and the optimum concentration for germination of pelleting seed was 1 %. Germination rate of the pelleted seeds treated with PID particulate material and PVP adhesive was higher (86.8%) than those of raw seeds (85.5%). $T_{50}$ and MDG of pelleted Codonopsis lanceolata seed required five and eight days at soil moisture content of 50%, respectively.
