산양삼은 산림청 특별관리 임산물로 지정되어 관리되고 있지만 체계적인 연구 나 표준 재배지침이 현장의 재배 현실과는 상이한 부분이 많은 실정이다. 이에 본 연구에서는 평창지역의 산양삼 재배지 환경조건에 따른 진세노사이드 함량이 어 떠한가를 알아보기 위하여 산양삼 시료를 각각 10본씩 채취하여 실험을 통해 확 인하였다. 산양삼 입지환경은 경사, 사면 방향, 해발고, 나무 종류, 흉고 직경과 수 고 등 모두 6가지를 조사하여 국립산림과학원의 분류기준을 참고하여 침엽과 활 엽으로 구분하였다. 산양삼 재배지의 토양산도를 포함한 9가지 토양이화학성 분석 에서는 전체적으로 침엽지역보다 활엽지역에서 높은 함량을 보였다. 통계분석 결 과에서는 A, B, C, 재배지에서 침엽과 활엽지역 간 통계적 유의성이 있는 것으로 나타났으며, D 재배지는 침엽과 활엽지역의 유의차가 거의 없는 것으로 나타났다. 진세노사이드 함유량 분석 결과에서는 Re, Rb1, Rg1의 순서로 높은 함량을 나타 내고 있어서 평창 산양삼의 주성분을 확인할 수 있었다. 연구 결과로 산양삼은 산 삼이 잘 생육할 수 있는 환경과 비슷한 곳을 재배지로 선정하여야 고품질의 제품 을 생산할 수 있다고 예상할 수 있다. 향후 본 연구 결과가 임업인 소득증대에 도 움을 줄 수 있는 자료로도 활용될 수 있기를 기대한다.

The aim of this study was to investigate the comparative growth characteristics and ginenoside contents of wild-simulated ginseng on different years (7 and 13-year-old) by monitoring soil properties of cultivation regions. Plant and soil samples were collected from 6 different cultivation regions. Soil organic matter (OM), total nitrogen (TN) and cation exchangeable capacity (CEC) were significantly higher in 13-year-old wild-simulated ginseng cultivation regions compared to 7-year-old wild-simulated ginseng cultivation regions. Growth characteristics of wild-simulated ginseng had shown significantly higher in 13-year-old wild-simulated ginseng compared to 7-year-old wild-simulated ginseng. Ginsenoside G-Rb1, Rb2, Rc, Rd, Re, Rf, Rg1 were significantly higher in 13-year-old wild-simulated ginseng than 7-year-old wild-simulated ginseng. According to the results of correlation analysis, soil OM, TN and CEC of the cultivated regions were positively correlated with the growth of wild-simulated ginseng. In addition, the root length of wild-simulated ginseng showed positive correlation with ginsenoside content. Hence, this study was able to investigate the correlation between growth and ginsenoside content of wild-simulated ginseng based on soil characteristics of the cultivation regions.

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.
