This study aims to subdivide consumers by attributes determined mainly by consumers of fresh ginseng. It is to compare and analyze the characteristics by cluster, and to deduce the implications on distribution and marketing. For this study, a survey was conducted targeting 250 consumers of fresh ginseng. The factors were deduced through performing the exploratory factor analysis on the results of the survey, and the consumers of fresh ginseng were classified through cluster analysis. As a result of the study, the attributes considered for the purchase of fresh ginseng were condensed to the three factors: physical characteristic factor, safety factor, and cultivation indication information factor. With these as the standard, the consumers of fresh ginseng were subdivided into the three clusters: safety-oriented consumption type, label-centered consumption type, and high involvement consumption type. It was found that there were differences in demographic characteristics and attributes considered for purchase of fresh ginseng by cluster analysis. This study suggests the implications for revitalization of the fresh ginseng industry by subdividing consumers of fresh ginseng and suggesting the characteristics by cluster.

Ginseng (Panax ginseng C.A. Meyer), one of the most widely used medicinal plants in traditional oriental medicine, is used for the treatment of various diseases. It has been classified according to its cultivation environment, such as field cultivated ginseng (FCG) and mountain cultivated ginseng (MCG). However, little is known about differences in gene expression in ginseng roots between field cultivated and mountain cultivated ginseng. In order to investigate the whole transcriptome landscape of ginseng, we employed High-Throughput sequencing technologies using the Illumina HiSeqTM2500 system, and generated a large amount of sequenced transcriptome from ginseng roots. Approximately 77 million and 87 million high-quality reads were produced in the FCG and MCG roots transcriptome analyses, respectively, and we obtained 256,032 assembled unigenes with an average length of 1,171 bp by de novo assembly methods. Functional annotations of the unigenes were performed using sequence similarity comparisons against the following databases: the non-redundant nucleotide database, the InterPro domains database, the Gene Ontology Consortium database, and the Kyoto Encyclopedia of Genes and Genomes pathway database. A total of 4,207 unigenes were assigned to specific metabolic pathways, and all of the known enzymes involved in starch and sucrose metabolism pathways were also identified in the KEGG library. This study indicated that alpha-glucan phosphorylase 1, putative pectinesterase/pectinesterase inhibitor 17, beta-amylase, and alpha-glucan phosphorylase isozyme H might be important factors involved in starch and sucrose metabolism between FCG and MCG in different environments.

Background: The ginsenosides Rb1 (G-Rb1) and Rg1 (G-Rg1) are used as marker compounds, and are the principal bioactive compounds assessed in the quality control of white ginseng. This study was conducted to analyze white ginseng samples of different and to obtain useful data for the quality control of white ginseng. Methods and Results: The variation in the content of G-Rb1 and G-Rg1 was evaluated among 35 samples of 4-, 5-, and 6-year-old white ginseng. The content of both G-Rb1 and G-Rg1 did not significantly differ among ages, and the relative ratio of the maximum to the minimum content of these within ginseng of the same ages was more than two. However, the ratio of G-Rb1 to G-Rg1 content in the 5- and 6-year-old ginseng was significantly higher than that in the 4-year-old one. According to the 'Ginseng industrial act', the standard (w/w, %) minimum $G-Rg_1$ and $G-Rb_1$ content is 0.10% and 0.20% or more, respectively. Among the 35 samples examined, the content of $G-Rg_1$ was found to be 0.124 - 0.399% with none being less than the standard level, while that of $G-Rb_1$, was 0.147 - 0.595%, with 4 samples (11.4%) failing to meet the standard levels. The content of $G-Rg_1$ and $G-Rb_1$ did not show a constant relationship with the size of ginseng. Conclusions: In our study, the content of both G-Rg1 and G-Rb1 varied widely, and there was no significant difference among cultivation ages. The results of the present study might provide useful information for the quality control of raw ginseng and processed white ginseng using marker compound.

Korean ginseng is a medicinally important perennial herb from the family Araliaceae. It has been cultivated for its highly valued medicinal properties for over 1,000 years in east Asian countries such as China, Korea, and Japan. Due to its longtime cultivation in shady areas, ginseng is frequently exposed to pathogenic infections. Plants protect themselves from microbial pathogens using an array of defense mechanisms, some of which are constitutively active, while others are activated upon pathogen invasion. These induced defense responses, controlled by defense-related genes, require tradeoffs in terms of plant fitness. We hypothesize that ginseng, as with other plants, possesses regulatory mechanisms that coordinate the activation of attacker-specific defenses in order to minimize fitness costs while attaining optimal resistance. Several classes of defense-related genes are induced by infection, wounds, irradiation, and other abiotic stresses. Both salicylates and jasmonates have been shown to cause such responses, although their specific roles and interactions in signaling and development are not fully understood in ginseng. This review summarizes possible defense-related genes in ginseng based on their expression patterns against biotic and abiotic stresses and describes their functional roles.

The patterns of saponins of lateral gingengs cultivated different areas and various ginseng products were investigated by quantitative thin-layer chromatography. In the case of ginseng cultivated in the Kum San and Gang Hwa area, some parts of the panaxatriol series of the saponins (peak 6 and 7.8.9) were higher in concentration than in ginseng grown in other areas while the other ingredients were almost the same. In the process of heat treatment the quantity of peak 2 was generally decreased. However, in the case of red and white ginseng, one part of the panaxatriol saponins, peak 6 was increased. This tendency was also found in honeyed ginseng and ginseng tea which were not exposed to sunlight, but the increase was much less. The change in the red and white ginseng which were exposed to sunlight was very substantial. Therefore we can assume that the increase of peak 6 comes about due to the combination of heat treatment and exposure to sunlight, especially due to exposure to sunlight.

The effects of ginseng extracts on carbon dioxide generation, alcohol fermentation, and yeast cell production by Saccharomyces cerevisiae were investigated. The results are as follows. 1) In the process of fermentation, CO2 generation by yeast is faster in ginseng extracts media of 0.3%, 0. l% than in control. As the concentration of the extracts increases by 0.7% and 1.5%, CO2 generation is decreased. Among all these concentrations, CO2 generation is fastest in 0.3% of the extracts. 2) In the process of fermentation, the production of alcohol is larger in the order of 0.3%, 0.7% and 0.1% than in the control and least in 1.5%. 3) The number of yeast cell rapidly increased from 12 hours to 18 hours after cultivation and conspicuously increased in the order of 0.3%, 0.7%, 0.1%, control and 1.5%. 4) Dried yeast cell weight increased more in all the above concentration than control and among these it increased visibly in 0.3% of the extracts.

Several attempts have been made to protect crops against injury from herbicide quinclorac residue in soil. In this experiment, a selection of suitable crops for bioassay of the residue and a reduction of phytotoxicity by treatment with active carbon were carried out to prevent or to counteract the phytotoxicity. Cucumber (Cuumts satims) and kidney bean (Phaseolus Mgaris) were the suitable indicator plant in points of a sensitivity to the herbicide residue and an easy cultivation. The phytotoxicity was able to be observed at 20 and 30 days after seeding on kidney bean and cucumber respectively. In pot trials, application of the active carbon at 50 kg/10a protected effectively the 2-year-old ginseng plant from the injury in a paddy soil where the herbicide had been treated at 3 g a. i./10a.
