  • This study was carried out to investigate the physicochemical characteristics of 3-year-old ginseng (for Samgyetang product) cultured by various seeding density in direct-sowing culture. Ginsengs were cultured by the seeding density, 275, 300, 330 352 and 396 seeds per Kan, $180{\times}90cm$ area. Survived rate (82.1%) were the highest in plot of 352 seeds sowed, length and leaf width were high in plot of 300 and 352 seeds. Root yield grain was increased with increase of the seeding density in direct-sowing culture except 352 seeds sowed. Average root weight and diameter were the highest in plot of 352 seeds sowed, 31.6 g and 18.4 mm, respectively. Crude saponin and each ginsenosides content were the highest in plot of 275 seeds sowed. Rg1 content was decreased, Rc and Rb2 content were increased with increase of the seeding density. Total soluble sugar content was the highest in plot of 330 seeds sowed and the lowest in plot of 396 seeds sowed, and oligo- and disaccaride content were high in plot of 330 and 352 seeds sowed. Reological characteristics of ginsengs cultivated according to various seeding density, hardness and springness were high and maximum fracture force was low with decrease of the seeding quantity.

  • Leaves from Panax ginseng Meyer (Korean origin and Chinese origin of Korean ginseng) and P. quinquefolius (American ginseng) were harvested in Haenam province, Korea, and were analyzed to investigate patterns in major metabolites using HPLC-based metabolic profiling. Partial least squares discriminant analysis (PLS-DA) was used to analyze the the HPLC chromatogram data. There was a clear separation between Panax species and/or origins from different countries in the PLS-DA score plots. The ginsenoside compounds of Rg1, Re, Rg2, Rb2, Rb3, and Rd in Korean leaves were higher than in Chinese and American ginseng leaves, and the Rb1 level in P. quinquefolius leaves was higher than in P. ginseng (Korean origin or Chinese origin). HPLC chromatogram data coupled with multivariate statistical analysis can be used to profile the metabolite content and undertake quality control of Panax products.

  • The aims of this study were to classify the cultivation status of medicinal crop farmers and to obtain basic data on domestic medicinal crops. To this end, 406 medicinal crop farmers participating in farming education programs in 14 cities and counties were surveyed over 10 months. The results were as follows. First, the biggest difficulty farmers faced in the overall production of medicinal crops was a lack of cultivation skills. Second, in a detailed inquiry about each difficulty item, the most difficult problems were injury by continuous cropping of root-using crops, shortage of specific farm machinery, uncertain market prices, and lack of knowledge about pest control or the positive list system (PLS). Third, the profitability of medicinal crops increased with career experience. Among the farmers who earned profits, requests for education and technical guidance were the most important factors for profitability. Fourth, the results of the analysis suggest that to achieve stable cultivation of medicinal crops, the following items need to be addressed: development and supply of basic cultivation technologies, climate response, registration of pest control pesticides, a solution to the injury by continuous cropping, and contracting cultivation expansion. Additionally, to improve profitability, it is necessary to create conditions that enable the same crops to grow for a long time in one region.

  • The effects of angiogenesis inhibitor from the extract libraries of Korean and Chinese medicinal plants were investigated using a protein microarray chip. Protein chip was constructed by immobilization of integrin ${\alpha}_5{\beta}_1$ on protein chip base plates and employed far screening active extracts that inhibit the integrin-fibronectin interaction from the extract libraries. The 100 extracts of medicinal plants were obtained from extract bank of National Institute of Crop Science, RDA. The 14 extracts among 100 extract libraries were shown efficient inhibition activity for the interaction between integrin-fibronectin. The medicinal plants of 14 extracts were Vitex negundo var. incisa (Lam.) C.B. Clarke, Epimedium koreanum Nakai, Cedrela sinensis A. Juss, Ipomea aquatica Forsk, Schisandra chinensis Baill, Pulsatilla koreana Nakai, Paeonia lactiflora Pall. var.hortensis Makino, Oenothera odorata, Allium chinense, Allium victorialis var. platyphyllum MAKINO, Polygonatum odoratum Druce var. pluriflorum Ohwi, Hosta lancifolia, Agrimonia pilosa L. var. japonica Nakai and Potentilla chinensis SER. The Paeonia lactiflora, Oenothera, and Agrimonia pilosa from these 14 extracts libraries were shown strong inhibition activity of integrin ${\alpha}_5{\beta}_1$.
