The purpose of this study is to determine the possibility of using cultured wild ginseng roots as a natural health food source. To accomplish this purpose, the contents of general and antioxidative nutrients of cultured wild ginseng roots were measured. The contents of carbohydrate, crude protein, crude lipid and ash are 61.72%, 17.36%, 0.23% and 10.90%, respectively. Further, the calories of cultured wild ginseng roots were 323.97 kcal. Total dietary fiber was 82.13%. The protein contained a total of 18 different kinds of amino acids. The contents of amino acids were 16.15 g. The K was the largest mineral followed by P, Ca, and Mg, which means cultured wild ginseng roots is alkali material. The contents of saturated fatty acids and unsaturated fatty acids were 0.23 g, and 0.62 g, respectively. Crude saponine content was 25.87 ㎎/g. Total phenolic contents of cultured wild ginseng roots were 11.2 ㎎/g, and total flavonoids contents were estimated as 4.2 ㎎/g. The electron donating ability of cultured wild ginseng roots were 24.7～31.6%. The nitrite scavenging activity was pH dependent, and was highest at pH 1.2 and lowest at pH 6.0. The cultured wild ginseng roots extract showed the highest reducing power (0.06) at the concentration of 1, 000 ㎍/㎖. Based on the above results, we deemed that the cultured wild ginseng roots might have potential antioxdant activities.

Background : The study about cultured wild ginseng root (Panax ginseng C. A. Meyer) have been reported mainly ginsenosides in saponins family. However metabolites of fermented wild ginseng roots by microorganisms was not reported yet. Methods and Results : Cultured wild ginseng roots were used for fermentation of ginseng roots using Pediococcus pentosaceus and other bacterial strains. We analyzed different types of ginsenoside contents, metabolite and enzyme contents, and gene expression by using microorganisms. Results showed considerable differences in ginseonoside contents specially Rk1 and Rg5. The highest enzyme activity level was by Glutathione reductase (GR) and Glutathione S transferase (GST) in fermented ginseng roots than control (non-fermented), whereas Glutathione peroxidase (GPX) and Peroxidase (POD) contents were reduced. Score plots and loading plots of principal components 1 of the PCA result obtained from the data on 43 metabolites in fermented wild ginseng root of five conditions. The concentration of metabolite such as β-alanin and 4-aminobutyric acid (GABA), which is used to improve memory were increased in fermented ginseng roots than control. We found functional gene in wild ginseng root related with metabolic process. The APX gene expression gradually increased in fermented ginseng root with respect to fermentation times. Conclusion : In this study, accumulation of functional metabolite in cultured ginseng r

The aim of the present study was to determine the effect of dietary cultured wild ginseng root (CWGR) supplementation on goat milk composition and ginsenoside profiles. Sixteen Saanen dairy goats were allocated to two balanced groups based on lactation period, body weight (38.6 ± 3.2 kg), and dairy milk yield (2.85 ± 1.2 kg), and were kept in separate pens. Goats were fed a total mixed ration (TMR) feed (2.3 kg/d, dry matter basis) and 1.5 g of CWGR powder was supplemented in the experimental diet. The total feeding period was 3 weeks, and milk and blood samples were collected on the last three days of the experimental period. There was no effect of CWGR on daily milk yield and milk composition (fat, protein, lactose, and solid-not-fat). However, the CWGR-treatment group had significantly higher plasma IgG and protein contents than the control group (P < 0.05). Significant amounts of ginsenosides were observed in the milk of the CWGR-treatment group, whereas ginsenosides were not detected in the milk of the control group. In conclusion, dietary CWGR was a useful regimen to produce functional goat milk enriched in ginsenosides.

Background : Ginsenosides, the main ingredient of ginseng roots can be confirmed various physiological activity such as anticancer, antioxidant, a natural ginsenosides is there a structure to be absorbed into the body does not work well absorbed through this process biologically active thus a high conversion ginsenosides. β-glucosidase enzyme is observed in several of the microorganism with an enzyme that serves to convert a ginsenoside prosper that is absorbed into the body. Methods and Results : To view a primary β-glucosidase activity, the bacteria were innoculated in esculin agar medium and the color change of the media were measured by the time and degree of changing color. In the other method, 5 mM of p-nitrophenyl-β-D-glucopyranoside (pNPG) containing 25 mM phosphate buffer solution (pH 7.0) was added to 50 ul enzyme solution. Then the solution was added to 50 ul reaction for 5 min at 30°C. The amount of p-nitrophenol liberated measured at 405 nm absorbance. The experimental results showed higher β-glucosidase activity in Pediococcus pentosaceus, Leuconostoc mesenteroide, Leuconostoc mesenteroides subsp. cremoris, and Paenibacillus polymyxa by using esculin agar medium method. Similarly in second method, β-glucosidase activity was higher in P. pentosaceus 402.32±11.43 unit/l, L. mesenteroide 353.73±14.64 unit/l, Lactobacillus sakei 198.4±15.47 unit/l Lactobacillus plantarum subsp. plantarum 164.1±8.12 unit/l. Conclusion : The result that the β-glucosidase activity was higher in P. pentosaceus, L. mesenteroide, and L. plantarum subsp. plantarum as compared to tested microbes. Therefore selected bacteria can be used in the industry of functioned foods and beverage to improve human healths.
