Muscle strength and endurance activities of Korean ginseng (Panax ginseng C. A. Meyer; KG) were compared with those of wild simulated cultivation ginseng (WCG) in mice. Fifty male ICR mice were divided into five groups: A (vehicle); B (WCG 100 mg/kg); C (WCG 500 mg/kg); D (KG 100 mg/kg); E (KG 500 mg/kg). Subsequently, the mice were subjected to the forced swimming test (FST) and treadmill test at the 4th and 7th weeks. The glycogen content in the muscle and blood analysis (levels of glucose, triglyceride (TG), IGF-1) were also performed immediately after the last FST and treadmill test at the 7th week. Immobility times in FST were shorter in WCG- than KG-treated groups, and the results of the treadmill tests were also significant except for KG-treated at 100 mg/kg. The glycogen content was increased in both groups with a peak at 500 mg/kg of WCG groups. Serum concentrations of TG and glucose were decreased by administration of KG and WCG and all treated groups showed increase in the level of IGF-1 in serum. These results suggest that KG and WCG supplementations are effective in escalating the muscle strength and endurance.

This study was performed to enhance contents of low molecular weight ginsenoside Rh2 and Rg3 using an ultra high pressure and steaming process in wild cultured-Root in wild ginseng. For selective increase in contents of Rg3 and Rh2 in cultured wild ginseng roots, an ultra high extraction was applied at 500MPa for 20 min which was followed by steaming process at 90℃ for 12 hr. It was revealed that contents of ginsenosides, Rb1, Rb2, Rc and Rd, were decreased with the complex process described above, whereas contents of ginsenoside Rh2 and Rg3 were increased up to 4.918 mg/g and 6.115 mg/g, respectively. In addition, concentration of benzo[α]pyrene in extracts of the cultured wild ginseng roots treated by the complex process was 0.64 ppm but it was 0.78 ppm when it was treated with the steaming process. From the results, it was strongly suggested that low molecular weight ginsenosides, Rh2 and Rg3, are converted from Rb1, Rb2, Rc, and Rd which are easily broken down by an ultra high pressure and steaming process. This results indicate that an ultra high pressure and steaming process can selectively increase in contents of Rg3 and Rh2 in cultured wild ginseng roots and this process might enhance the utilization and values of cultured wild ginseng roots.

산삼배양근을 식품소재 첨가물로의 이용성을 알아보고자 열수 및 70% 에탄올 추출물에 대한 항산화 활성을 측정하였다. 열수추출물의 수율은 건물당 27.86%이었으며, 70% 에탄올추출물은 18.33%이었다. 총 폴리페놀 함량은 열수 및 70% 에탄올 추출물에서 각각 17.90 mg/g 및 22.63 mg/g 이었다. Ginsenoside Rb1 및 Rg1의 함량은 각각 1.45 mg/g 및 0.96 mg/g 이었다. 1~20 mg/mL 농도에서 물

The objective of this study was to assess genetic diversity among 6 different wild ginseng populations from New York, Kentucky, North Carolina, Pennsylvania, Tennessee and Virginia, and to compare these wild populations to one cultivated population. RAPD markers were used to estimate the genetic difference among samples from the 7 populations. The 64 random primers were screened, and 15 primers were selected which exhibited the 124 highly reproducible polymorphic markers. The ratio of discordant bands to total bands scored was used to estimate the genetic distance within and among populations. Multidimensional scaling (MDS) of the relation matrix showed distinctive separation between wild and cultivated populations. The MDS result was confirmed using pooled chi-square tests for fragment homogeneity. This study suggests that RAPD markers can be used as population-specific markers for American ginseng.

배양산삼근을 5 및 (w/v)를 첨가하고, 설탕과 포도당으로 당도를 Brix로 조절한 후, 3종의 효모를 이용하여 발효주를 제조하였다. 발효기간 중 품질특성(알콜함량, 사포닌함량, 효모균수, 총산도, 당도, 휘발성성분)을 조사하고 관능검사를 실시하였다. 배양산삼근 , 포도당 및 S. bayanus (ATCC 10601) 효모 처리구에서 의 가장 높은 알콜함량을 보였으며 주된 알콜성분은 ethanol과 1-propanol이었다. 효모균수는 발효 5
