본 연구는 환경정화에 주로 사용되는 미세기포를 2년 근 인삼 지속적으로 처리하여 인삼이 성장하면서 변화되는 형태와 ginsenoside 변화를 조사하는 융합적 연구이다. 인삼 재배시 미세기포수를 적용하여 4개월 동안(120일) 재배한 후 인삼의 잎과 뿌리의 부위별 ginsenoside 함량과 조성을 분석하였다. 잎에 일반수를 처리한 결과 protopanaxatriol(PPT) 계열 Re 함량만 월등히 높게 나타났지만 미세기포수를 처리한 결과 protopanaxadiol(PPD) 계열 Rb1, RC, Rb2, Rd 성분도 같이 증가시키는 것을 확인하였다. 특히 Re, Rb1이 다량 증가함으로써 전체적인 total ginsenoside가 증가하는 요인이 되었다. 인삼의 부위별 PD/PT 비율은 미세기포수를 처리한 잎에서는 0.811으로 나타나고 뿌리는 1.28로 나타났다. 이것은 미세기포수 처리가 뿌리에서 ginsenoside의 합성을 유도하여 PD/PT 비율이 1과 가까운 결가를 가져와 유용성분의 증가 및 고른 분포 이루어졌다고 판단된다. 따라서 미세버블수를 사용한 고품질 인삼을 생산하는 재배 방법을 제시하고 인삼의 뿌리와 더불어 잎도 기능성 식품 소재로 활용할 수 있는 가능성을 제시하였다.

버미큐라이트 폿드 시험으로 묘삼(苗蔘)의 양액재배(養液栽培)에서 N.P.K.의 수준(水準)을 달리하여 근중 ginsenoside의 함량변화(含量變化)를 조사(調査)하였다. 이들 중 어느 하나의 결제 또는 증가는 사포닌 함량(含量)의 증가 또는 감소를 보였다. 사포닌 함량에 영향을 가장 크게 주는 것은 질소이고(15.5%에서 8.9%) P.K.의 순(順)이었다. 각 ginsenoside 함량에서도 유사(類似)한 결과를 보였다. 양분환경변화에 의한 함량변이(含量變異)의 순위(順位)는 $Rd>Rb_1>Rg_1+Rf>Rc>Rg_2{\geqq}Rb_2>Re$로 Re가 가장 둔감하며 다른 요인에 관하여도 둔감할 것으로 보였다. Diol 총량이 triol 총량보다 민감하나 이들의 비(比)는 절반의 변이계수를 보였다. 영양조건에 의한 각(各) ginsenoside의 변이(變異)는 그 함량(含量)과는 무관(無關)하였다. Ginsenoside pattern의 유사도(類似度)는 총 사포닌 함량에 차이가 큰 처리간에서 낮아졌다. 뿌리의 생육(生育)은 수도수구(水道水區)에서만 유의성있게 적었다.

Background: Red ginseng (RG) is processed from Panax ginseng via several methods including heat treatment, mild acid hydrolysis, and microbial conversion to transform the major ginsenosides into minor ginsenosides, which have greater pharmaceutical activities. During the fermentation process using microbial strains in a machine for making red ginseng, a change of composition occurs after heating. Therefore, we confirmed that fermentation had occurred using only microbial strains and evaluated the changes in the ginsenosides and their chemical composition. Methods: To confirm the fermentation by microbial strains, the fermented red ginseng was made with microbial strains (w-FRG) or without microbial strains (n-FRG), and the fermentation process was performed to tertiary fermentation. The changes in the ginsenoside composition of the self-manufactured FRG using the machine were evaluated using HPLC, and the 20 ginsenosides were analyzed. Additionally, we investigated changes of the reducing sugar and polyphenol contents during fermentation process. Results: In the fermentation process, ginsenosides Re, Rg1, and Rb1 decreased but ginsenosides Rh1, F2, Rg3, and Compound Y (C.Y) increased in primary FRG more than in the raw ginseng and RG. The content of phenolic compounds was high in FRG and the highest in the tertiary w-FRG. Moreover, the reducing sugar content was approximately three times higher in the tertiary w-FRG than in the other n-FRG. Conclusion: As the results indicate, we confirmed the changes in the ginsenoside content and the role of microbial strains in the fermentation process.

The purpose of this study was to develop a new preparation process of ginseng extract using high concentrations of ginsenoside $Rg_3$, a special component in red ginseng. From when the ginseng saponin glycosides transformed into the prosapogenins chemically, they were analyzed using the HPLC method. The ginseng and ginseng extract were processed with several treatment conditions of an edible brewing vinegar. The results indicated that ginsenoside $Rg_3$ quantities increased over 4% at the pH 2-4 level of vinegar treatment. This occurred at temperatures above $R90^{\circ}C$, but not occurred at other pH and temperature condition. In addition, the ginseng and ginseng extract were processed with the twice-brewed vinegar (about 14% acidity). This produced about 1.5 times more ginsenoside $Rg_3$ than those processed with regular amounts of brewing vinegar (about 7% acidity) and persimmon vinegar (about 3% acidity). Though the white ginseng extract was processed with the brewing vinegar over four hr, there was no change for ginsenoside $Rg_3$. However, the VG8-7 was the highest amount of ginsenoside $Rg_3$ (4.71%) in the white ginseng extract, which was processed with the twice-brewed vinegar for nine hr. These results indicate that ginseng treated with vinegar had 10 times the quantity of ginsenoside $Rg_3$, compared to the amount of ginsenoside $Rg_3$ in the generally commercial red ginseng, while ginsenoside $Rg_3$ was not found in raw and white ginseng.

Seasonal ginsenoside flux in the leaves of 5-year-old Panax ginseng was analyzed from the field-grown ginseng, for the first time, to study possible biosynthesis and translocation of ginsenosides. The concentrations of nine major ginsenosides, Rg1, Re, Rh1, Rg2, R-Rh1, Rb1, Rc, Rb2, and Rd, were determined by UHPLC during the growth in between April and November. It was confirmed total ginsenoside content in the dried ginseng leaves was much higher than the roots by several folds whereas the composition of ginsenosides was different from the roots. The ginsenoside flux was affected by ginseng growth. It quickly increased to 10.99±0.15 (dry wt%) in April and dropped to 6.41±0.14% in May. Then, it slowly increased to 9.71±0.14% in August and maintained until October. Ginsenoside Re was most abundant in the leaf of P. ginseng, followed by Rd and Rg1. Ginsenosides Rf and Ro were not detected from the leaf. When compared to the previously reported root data, ginsenosides in the leaf appeared to be translocated to the root, especially in the early vegetative stage even though the metabolite translocated cannot be specified. The flux of ginsenoside R-Rh1 was similar to the other (20S)-PPT ginsenosides. When the compositional changes of each ginsenoside in the leaf was analyzed, complementary relationship was observed from ginsenoside Rg1 and Re, as well as from ginsenoside Rd and Rb1+Rc. Accordingly, ginsenoside Re in the leaf was proposed to be synthesized from ginsenoside Rg1. Similarly, ginsenosides Rb1 and Rc were proposed to be synthesized from Rd.

This study was conducted to provide basic information on ginseng saponin of dried ginseng radices. In order to achieve the proposed objective ginsenoside compositions of dried ginseng radices extract with 70% ethyl alcohol were examined by HPLC. The total saponin content, the sum of all ginsenosides, showed that Wild simulated ginseng (WSG), White fine ginseng (WFG), Skin White ginseng (SWG), and White ginseng (WG) stood at 2.510%, 1.643%, 0.587, and 0.429%, respectively. WSG in PPD/PPT ratio was highest at 3.190, WFG (1.934), WG (1.600), SWG (1.386) in order. In the content of ginsenoside Rb1, one of the marker compounds of ginseng, WSG (1.095%) showed the highest content, and WFG (0.527%), SWG (0.246%), WG (0.133%) in this order. The content of ginsenoside Rb1 of WSG (1.095%) was 4.5 times higher than SWG (0.246%). WSG (0.230%) showed the highest content in ginsenoside Rg1, a marker compounds of ginseng, followed by WFG (0.180%), SWG (0.141%) and WG (0.086%). The content of ginsenoside Rg1 of WSG (0.230%) was 1.6 times higher than SWG (0.141%).

Red ginseng and fermented red ginseng were prepared, and their composition of ginsenosides and antiischemic effect were investigated. When ginseng was steamed at 98-$100{\circ}C$ for 4h and dried for 5h at $60{\circ}C$, and extracted with alcohol, its main components were ginsenoside $Rg_3$ > ginsenoside $Rg_1$> ginsenoside $Rg_2$. When the ginseng was suspended in water and fermented for 5 days by previously cultured Bifidobacterium H-1 and freeze-dried (fermented red ginseng), its main components were compound K > ginsenoside $Rg_3{\geq}$ ginsenoside $Rg_2$. Orally administered red ginseng extract did not protect ischemia-reperfusion brain injury. However, fermented red ginseng significantly protected ischemica-reperfusion brain injury. These results suggest that ginsenoside Rh2 and compound K, which was found to be at a higher content in fermented red ginseng than red ginseng, may improve ischemic brain injury.

This work was carried out to establish adventitious root culture system in three Panax species (wild-grown P. ginseng, P. quinquefolium, and P. japonicum) to analyze their ginsenoside productivity. Adventitious roots were induced directly from segments of seedlings after cultured on MS(Murashige andSkoog 1962) solid medium containing 3.0 mg/l IBA. Omission of $NH_4NO_3$ from the medium greatly enhanced both the frequency of adventitious root formation and number of roots per explants in all the three Panax species. However, elongation of post-induced adventitious roots was enhanced on medium with $NH_4NO_3$. Two-step culture protocol: $NH_4NO_3$-free medium for first two weeks of culture, followed by $NH_4NO_3$ containing medium for further 4 weeks, greatly enhanced the fresh weight increase of adventitious roots in all the three ginseng species. The fresh weight of adventitious roots was high in P. quinquefolium and low in P. ginseng, followed by P. japonioum regardless of the composition of medium. Pattern and content of ginsenosides in adventitious roots differed among the three Panax species. Total ginsenoside content of adventitious roots in P. quinquefolium, P. ginseng, and p. japonicum was 8.03, 15.7 and 1.2 mg/g dry weight, respectively. Among the three speices, adventitious roots in P. quinquefolium produced hig-hamount of ginsenosides. The pattern of ginsenoside fractions between P. ginseng and P. quinquefolium was similar but the amount of ginsenoside differed between the two, While, in P japonicum, total ginsenoside content was very low and some ginsenosides such as ginsenoside Rb2 and Rf were not detected. Conclusively, we demonstrate that same culture condition was required for induction and elongation of adventitious roots of three ginseng species but growth of adventitious roots and their ginsenoside production were different among them.

인삼을 재배한 후 널리 이용되지 못하고 있는 잎, 줄기 등 인삼 부산물의 활용방안을 모색하고자 연구를 수행하였다. 이에 따라 인삼잎과 줄기를 혼합하여 추출한 추출물을 대상으로 일반 영양성분 함량, 무기질 함량, 아미노산 및 지방산 조성을 분석하고 세포독성에 미치는 영향을 조사하여 다음과 같은 결과를 얻었다. 인삼잎, 줄기 혼합 추출물의 수분함량은 96.61%, 탄수화물 2.51%, 조회분 0.53%, 조지방 0.20% 및 조단백질이 0.15%이었다. 무기질 중 칼륨함량이 102.56 mg/100 g으로 가장 높았고 그 외 칼슘, 마그네슘, 나트륨, 인 및 철분, 망간, 아연, 구리도 함유되어 있었다. Glutamic acid와 aspartic acid 등 산성아미노산 함량이 높게 나타났고 필수아미노산이 모두 함유되어 있었다. 또한 불포화지방산 함량은 56.52%이었고 palmitic acid 함량이 39.99%로 가장 높았고, linoleic acid 14.96%, docosatetranoic acid 13.31%, linolenic acid 12.19%의 순이었다. 인삼의 총 ginenoside 함량은 0.82 mg/mL이 었고 PD/PT 함유 비율은 0.68이었다. 정상적인 간과 신장 세포의 생존율에는 negative effect를 나타내지 않았고 미토콘드리아와 라이소좀 수준에서 세포독성을 나타내지 않았다. 인삼잎, 줄기 혼합 추출물의 약리효능을 나타내는 gensenoside의 함량이 0.82 mg/mL로서 비교적 소량 함유되어 있으나 인삼 부산물의 활용차원에서 동물의 사료나 기능성 식품 재료로의 사용은 가능할 것으로 생각된다. 향후 동물실험 및 임상실험을 이용한 기능성 평가를 통해 확실하고 구체적인 활용방안의 모색이 요구되어진다.

The objective of this research is to provide basic information necessary to differentiate between ginseng (Panax ginseng) grown in woods environments and cultivated ginseng. The ginseng saponin (ginsenoside) contents of Korean woods-grown, 4 year-old cultivated, and 6 year-old cultivated ginsengs were determined via HPLC analysis. The total saponins in the woods-grown ginseng (0.648%) were approximately twice that of the 4 year-old cultivated (0.270%) and the 6 year-old cultivated ginsengs (0.280%). The protopanaxadiols (PD)/protopanaxatriols (PT) ratio of the woods-grown ginseng (3.258%) was higher than that of the 4 year-old cultivated (2.456%) and the 6 year-old cultivated ginsengs (2.183%). The $Rb_1/Rg_1$ ratio of the woods-grown ginseng (10.225%) was also higher than those of the 4 year-old cultivated (3.514%) and the 6 year-old cultivated ginsengs (4.865%).
