Background: Ginseng (Panax ginseng Meyer) is one of the world's most valuable medicinal plants with numerous pharmacological effects. Ginseng has been cultivated from wild mountain ginseng collections for a few hundred years. However, the genetic diversity of cultivated and wild ginseng populations is not fully understood. Methods: We developed 92 polymorphic microsatellite markers based on whole-genome sequence data. We selected five markers that represent clear allele diversity for each of their corresponding loci to elucidate genetic diversity. These markers were applied to 147 individual plants, including cultivars, breeding lines, and wild populations in Korea and neighboring countries. Results: Most of the 92 markers displayed multiple-band patterns, resulting from genome duplication, which causes confusion in interpretation of their target locus. The five high-resolution markers revealed 3 to 8 alleles from each single locus. The proportion of heterozygosity (H_e) ranged from 0.027 to 0.190, with an average of 0.132, which is notably lower than that of previous studies. Polymorphism information content of the markers ranged from 0.199 to 0.701, with an average of 0.454. There was no statistically significant difference in genetic diversity between cultivated and wild ginseng groups, and they showed intermingled positioning in the phylogenetic relationship. Conclusion: Ginseng has a relatively high level of genetic diversity, and cultivated and wild groups have similar levels of genetic diversity. Collectively, our data demonstrate that current breeding populations have abundant genetic diversity for breeding of elite ginseng cultivars.

Activity-guided fractionation of an ethyl acetate (EtOAc)-soluble portion of an ethanolic extract from the leaves of cultivated mountain ginseng, using pancreatic lipase inhibition assay, led to the isolation and identification of three flavonoids of a previously described structure, kaempferol-3-O-sophoroside (I), kaempferol-3-O-${\beta}$-Dglucopyranoside (astragalin, II) and kaempferol (III). All compounds (I.III) showed pancreatic lipase inhibitory activities, with $IC_{50}$ values ranging from $20.3{\pm}2.2$ to $9.1{\pm}1.5$ ${\mu}M$, kaempferol (III) showed the most potent inhibitory activity with an $IC_{50}$ of $9.1{\pm}1.5$ ${\mu}M$. The level of activity may depend on the number of C-3 glucosyl group(s) linked to the kaempferol backbone, and the isolated compounds may have promise as pancreatic lipase inhibitors.

This study investigated that comparison of the nutrients (including fatty acids, amino acids, and minerals) and ginsenoside, total phenolic (TP) and total flavonoid (TF) contents and antioxidant activities in 5-year-old cultivated ginseng (CG), mountain-cultivated ginseng (MCG), and whole plant parts of MCG (WPMCG). The contents of total fatty acids and unsaturated fatty acids were determined highest in MCG (1215.9 and 751.2 mg/100 g), and saturated fatty acid was determined highest in WPMCG (486.4 mg/100 g) respectively. Characteristically, the α-linolenic acid content was detected up to 10 times higher in MCG (139.3 mg/100 g) and WPMCG (194.4 mg/100 g) compared to CG (18.1 mg/100 g). Total free and essential amino acid contents were high with CG < MCG < WPMCG (1006.35 mg/100 g and 839.46 mg/100 g). Notably, γ-aminobutyric acid and arginine were detected as the main non-essential amino acids with highest levels detected in WPMCG (163.10 mg/100 g) and MCG (305.23 mg/100 g), respectively. Total mineral content was high in CG (30.36 mg/100 g) and WPMCG (29.82 mg/100 g). Particularly, Calcium (Ca) was detected more than twice as high in WPMCG (6.68 mg/100 g) as compared to CG and MCG. TP and TF contents were 5.12 gallic acid mg/g and 3.04 RE mg/g respectively. Ginsenoside content was the highest in WPMCG (42.44 mg/g) in general and the highest antioxidant activity was also observed in WPMCG.

The purpose of this study is classifying types of American ginseng and estimating their production cost and revenue by the types. Usually, the American ginseng can be classified as 4 different types; wild ginseng(WG), wild simulated ginseng(WSG), woods grown ginseng(WGG), and field cultivated ginseng(FCG). This paper estimates costs and benefits for FCG, WGG, and WSG per acre. The WGG & WSG are produced under the tree at mountain while the FCG is produced at large scale farm with machinery. Annual profit for the FCG is $2,222 while that of the WGG and the WSG are $2,759 and $3,799 per acre. Although quantity produced per acre for the WGG and WSG(600lbs and 160lbs) are much smaller than that of the FCG(3,000lbs), prices per pound for the WGG and WSG($125, 375$) are higher than that of the FCG($24). In addition, production costs for the WGG and WSG are lower than that of the FCG because of the costs for seeds, shadow facility, and chemicals are different by the types of production.

This research is to investigate the four years growth mountain-cultivated ginseng ripened twenty-two weeks into four years fermented persimmon vinegar (tentatively: Sansamcho) ingestion on obese-related factors during dietary control. The Sansamcho was ingested orally, two times a day, after every meal for six weeks to the male rats. Groups were divided into the control (CON), the restricted diet (RD), and the weight cycling (WC). And, each groups has its own sub-groups as the -control (-CON), 2.5 times diluted Sansamcho ingestion (-MPV2.5), and 5.0 times diluted Sansamcho ingestion (-MPV5.0) groups, respectively. The number of rat was consisted of seven in each group. After six weeks rearing periods was done, abdominal fats (retroperitoneal fat, mesentery fat, and epididymal fat) and energy metabolic-related protein (AMPK: AMP-activated protein kinase; PPAR-${\alpha}$: peroxisome proliferator-activated receptor-${\alpha}$; and CPT-1: carnitine palmitoyltransferase-1) were weighed and analyzed. Amount of stored fat was significantly or tended to decrease by Sansamcho ingestion. In addition, sum of fats increasing were suppressed by the material. On the contrary, energy metabolism-related protein expression was significantly increased or tended to increase by Sansamcho ingestion. This results suggested that increased energy metabolism using Sansamcho was restrained effectively visceral fat store by high-fat diet and/or dietary control. In other words, it has a good function to suppress weight cycling which is the most insoluble problem. Therefore, the fusion material, Sansamcho, may expect to utilize as the obese-suppression-food.

The purpose of this study was to investigate the anti-apoptosis-related protein expression in skeletal muscle of rats with different amount of mountain ginseng (MG) added high-fat diet fed. Twenty-four Sprague Dawley male rats were divided into the high-fat diet control group (CON), 0.5% of MG added diet group (MG1), and 1.0% of MG added diet group (MG2) with eight rats each. The P53, anti-apoptotic protein, was significantly lower in MG2 than CON and MG1. The bcl-2 and bcl-xl, however, were not significantly different from MG1 but from CON. The caspase-9 and -3, were significantly lower in MG groups than CON. In addition, it was dramatically lower in MG2. These results suggested that MG addition to the high-fat diet suppressed p53 protein expression and enhanced anti-apoptototic protein expression. MG may be a positive effects on health as a medicinal plant.

The purpose of this study is to investigate the changes of ginseng properties through bibliographical records. The cultivation of Korean wild simulated ginseng (mountain cultivated ginseng) started from the Goryeo Dynasty around A.D. 1000. Thereafter, from A.D. 1500 to A.D. 1600, ginseng cultivation technology was established in the Joseon Dynasty. At this time, the ginseng was begun to grow in the field near the house, and it is recorded as Gasam (field cultivated ginseng). The Jung-Jo-Sil-Rok (A.D. 1790) states that Gasam cultivation has expanded to the whole country. The properties of ginseng described in almost all oriental medicine books from A.D. 250 to A.D. 1600 were a slightly cold. However, after A.D. 1600, it is said to be slightly warm or warm. Considering from this record, the slightly cold ginseng before A.D. 1600 can be recognized as the properties of wild ginseng or wild simulated ginseng, and the slightly warm ginseng after A.D. 1600 can be recognized as Gasam properties.

Phylogenetic relationships among species in Araliaceae were analyzed using PCR-RAPD and sequence of ITS region of nuclear ribosomal DNA based on samples collected in Korea. RAPD analysis showed various polymorphic bands which were able to differentiate species and genus, and specific bands showing variations among individuals within species. Cluster analysis using gel images revealed high molecular variability within species of Aralia eleta. No significant variation was found among cultivated species of Panax ginseng, but they showed high genetic differences with wild type of the species. In ITS analysis, specific sequences for each genus and species were observed and these were allowed to differentiate species and genus. Phylogenetic analysis using ITS sequences showed that Acanthopanax and Kalopanax had a close relationship, and Aralia and Panax are monophyletic, but genus Hedera is different species from other species in family Araliaceae in this study. The results showing close relationship between genera Aralia and Panax were also observed in RAPD analysis. Contrary to the results of RAPD analysis of Panax ginseng, sequence analysis of ITS showed no significant difference between wild mountain ginseng and cultivated species of P. ginseng. Also, both RAPD and ITS analysis of P. ginseng showed no significant genetic variability among cultivation sites. Results indicate that P. ginseng cultivating in Korea is monophyletic. The molecular analysis used in this study agreed on classification using morphological feature. These results suggest that molecular techniques used in this study could be useful for phylogenetic analysis of Araliaceae.
