Mountain-cultivated Ginseng Research Articles

Persimmon vinegar ripening with the mountain-cultivated ginseng ingestion reduces blood lipids and lowers inflammatory cytokines in obese adolescents.

[Purpose]This study investigated the effect of the vinegar, which is made of 4-year-old mountain-cultivated ginseng ripened into 4-year-matured persimmon vinegar, on the blood lipids level and inflammatory cytokines concentration in obese female adolescents.[Methods]Subjects ingested the vinegar, so-called 'mountain-cultivated ginseng persimmon vinegar (MPV)', without meals every day for 6 weeks with activities control. Subjects were grouped into control (CON), persimmon vinegar (PV), and MPV with 10 people in each group. Blood lipids, triglyceride (TG), total-cholesterol (TC), and high density lipoprotein-cholesterol (HDL-C) were analyzed. Also, glutamic oxaloacetic transaminase (GOT) and glutamate pyruvate transaminase (GPT) were analyzed for the hepatotoxicity. Blood cytokines, interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), and nuclear factor kappa-light-chain-enhancer of activated B cells (NFκB) were analyzed.[Results]Subjects showed a high reduction in body weight and body fat. Their blood lipid level was effectively improved, and the secretion of inflammatory cytokine was suppressed as well, except for TNF-α. However, the change ratio of the cytokines was high in PV and MPV. Such results were similar to those from research subjects who took persimmon vinegar only (PV), but the effect of the vinegar (MPV) was more remarkable. Besides, this mixture was found to have no effect on the hepatotoxicity.[Conclusion]The significance of this study is that all the experiments were conducted without controlling research subjects' daily lives, and it is suggested that the vinegar may be recommended as a kind of health supplement food to suppress obesity. Especially, since these two products are traditional foods of Korean people, which have been taken for ages, it is expected that the fusing of two foods may be better applied to ordinary people who are concerned about obesity.

Soil properties of cultivation sites for mountain-cultivated ginseng at local level

BackgroundIdentifying suitable site for growing mountain-cultivated ginseng is a concern for ginseng producers. This study was conducted to evaluate the soil properties of cultivation sites for mountain-cultivated ginseng in Hamyang-gun, which is one of the most well-known areas for mountain-cultivated ginseng in Korea. MethodsThe sampling plots from 30 sites were randomly selected on or near the center of the ginseng growing sites in July and August 2009. Soil samples for the soil properties analysis were collected from the top 20 cm at five randomly selected points. ResultsMountain-cultivated ginseng was grown in soils that varied greatly in soil properties on coniferous, mixed, and deciduous broad-leaved stand sites of elevations between > 200 m and < 1,000 m. The soil bulk density was higher in Pinus densiflora than in Larix leptolepis stand sites and higher in the < 700-m sites than in > 700-m sites. Soil pH was unaffected by the type of stand sites (pH 4.35–4.55), whereas the high-elevation sites of > 700 m were strongly acidified, with pH 4.19. The organic carbon and total nitrogen content were lower in the P. densiflora stand sites than in the deciduous broad-leaved stand sites. Available phosphorus was low in all of the stand sites. The exchangeable cation was generally higher in the mixed and low-elevation sites than in the P. densiflora and high-elevation sites, respectively. ConclusionThese results indicate that mountain-cultivated ginseng in Korea is able to grow in very acidic, nutrient-depleted forest soils.

Diversity of Endophytic Fungi Isolated from Korean Ginseng Leaves

We investigated the diversity of the foliar endophytes of Korean ginseng. Endophytic fungi were isolated from healthy leaves of mountain-cultivated ginseng (MCG) and field-cultivated ginseng (FCG) at 4 sites in Chungbuk Province. A total of 24 species of fungal endophytes were identified using molecular approaches. Additionally, the diversity of these endophytic fungi was compared between MCG and FCG. The major isolated endophytes were Edenia gomezpompae and Gibberella moniliformis in the MCG and FCG samples, respectively. The results suggest that ginseng endophytes have different community structures in different environments, and this understanding may prove useful in ginseng cultivation.

Mountain cultivated ginseng (MCG) is a type of Panax ginseng C. A. Mayer, grown in the mountains by artificial seeding. In general, it has been known that the biophysical activities of MCG is greater than that of ginseng. However, the in vivo efficacy of MCG on cancer has not been studied. In this study, we investigated the anti-carcinogenic effect of MCG and ginseng using the 7,12-dimethylbenz[a]anthracene (DMBA)-12-O-tetradecanoylphorbol- 13-acetate (TPA) two stage mouse skin carcinogenesis model. Six weeks of female ICR mice were divided into control, MCG, and ginseng diet groups and were subjected into two different experimental protocols. In the first study, each experimental diet was fed with TPA promotion for 24 weeks. The result showed that supplementation of MCG reduced tumor incidence, tumor multiplicity, and tumor size compared to those of the control and ginseng groups. In the second study, 3 groups of mice were supplied with each diet 4 weeks before DMBA tumor initiation, until the end of experiment. The result showed that tumor incidence, tumor multiplicity, and tumor size were reduced in the ginseng diet group compared to those of the control and MCG groups. TPA-induced BrdU incorporation was also significantly reduced in the ginseng diet group. Taken together, these results suggest that MCG is chemotherapeutic, whereas ginseng has a chemopreventative effect on mouse skin cancer.

RETRACTED: Identification and Analysis of Differentially Expressed Genes in Mountain Cultivated Ginseng and Mountain Wild Ginseng

Ginseng is one of the most widely used herbal medicines in the world. Wild ginseng is thought to be more effective than cultivated ginseng in chemoprevention; however, little has been reported on the differences between wild and cultivated ginseng. In the present study we used suppressive subtractive hybridization to identify wild ginseng-specific genes. One of the clones isolated in this screen was the NRT2 gene (designated pNRT2), a high-affinity nitrate transporter. Real-time reverse transcription-polymerase chain reaction results showed that pNRT2 expression was significantly upregulated in wild ginseng compared with cultivated ginseng. However, pNRT2 mRNA levels were similar between mountain cultivated ginseng and mountain wild ginseng. Nitrate is an important nitrogen source for plant growth, and its soil levels can vary in wild environments; thus it is conceivable that pNRT2 expression is upregulated in wild ginseng and may be an important marker of wild ginseng.

Differentiation of the root of Cultivated Ginseng, Mountain Cultivated Ginseng and Mountain Wild Ginseng using FT-IR and two-dimensional correlation IR spectroscopy

Ginseng is one of the most widely used herbal medicines. Based on the grown environments and the cultivate method, three kinds of ginseng, Cultivated Ginseng (CG), Mountain Cultivated Ginseng (MCG) and Mountain Wild Ginseng (MWG) are classified. A novel and scientific-oriented method was developed and established to discriminate and identify three kinds of ginseng using Fourier transform infrared spectroscopy (FT-IR), secondary derivative IR spectra and two-dimensional correlation infrared spectroscopy (2D-IR). The findings indicated that the relative contents of starch in the CG were more than that in MCG and MWG, while the relative contents of calcium oxalate and lipids in MWG were more than that in CG and MCG, and the relative contents of fatty acid in MCG were more than that in CG and MWG. The hierarchical cluster analysis was applied to data analysis of MWG, CG and MWG, which could be classified successfully. The results demonstrated the macroscopic IR fingerprint method, including FT-IR, secondary derivative IR and 2D-IR, can be applied to discriminate different ginsengs rapidly, effectively and non-destructively.

Physiological and chemical characteristics of field-and mountain-cultivated ginseng roots

Demand is increasing for mountain-cultivatedPanax ginseng (MCG) because its quality is considered superior to that of field-cultivated ginseng (FCG). However, MCG grows very slowly, and the factors that might affect this are unknown. In addition, little information is available about the physiological characteristics of its roots. Here, we investigated local soil environments and compared the histological and chemical properties of MCG and FCG roots. Average diameters, lengths, and fresh weights were much smaller in the former. Photosynthesis rates and root cambial activity also were reduced in the MCG tissues. Our analysis of soil from the mountain site revealed an extremely low phosphorus content, although those samples were richer in total nitrogen and organic matter than were the field soils. MCG roots also contained higher amounts of ginsenosides, and total accumulations increased with age. Moreover, ginsenoside Rh2, a red ginseng-specific compound, accumulated in the MCG roots but not in those from FCG plants. Interestingly, numerous calcium oxalate crystals were found in MCG roots, particularly in their rhizomes (i.e., short stems). Therefore, we can conclude from these results that low levels of the essential mineral phosphorus in mountain soils are a critical factor that retards the growth of mountain ginseng. Likewise, the high accumulation of calcium oxalate crystals in MCG roots might be an adaptation mechanism for survival in such a harsh local environment.
