We aimed to compare the content of ginsenosides and the pharmacokinetics after the oral administration of four different ginseng products at a dose of 1 g/kg in rats. The four different ginseng products were fresh ginseng extract, red ginseng extract, white ginseng extract, and saponin enriched white ginseng extract prepared from the radix of Panax ginseng C.A. Meyer. The ginsenoside concentrations in the ginseng product and the rat plasma samples were determined using a liquid chromatography-tandem mass spectrometry (LC-MS/MS). Eight or nine ginsenosides of the 15 tested ginsenosides were detected; however, the content and total ginsenosides varied depending on the preparation method. Moreover, the content of triglycosylated ginsenosides was higher than that of diglycosylated ginsenosides, and deglycosylated ginsenosides were not present in any preparation. After the single oral administrations of four different ginseng products in rats, only four ginsenosides, such as 20(S)-ginsenosides Rb1 (GRb1), GRb2, GRc, and GRd, were detected in the rat plasma samples among the 15 ginsenosides tested. The plasma concentrations of GRb1, GRb2, GRc, and GRd were different depends on the preparation method but pharmacokinetic features of the four ginseng products were similar. In conclusion, a good correlation between the area under the concentration curve and the content of GRb1, GRb2, and GRc, but not GRd, in the ginseng products was identified and it might be the result of their higher content and intestinal biotransformation of the ginseng product.

구증구포방법은 기존의 홍삼제조방법에서와 같이 9회 반복 과정으로 새로운 신규사포닌 등 성분변화가 일어나지만 시간이 오래 걸리고 복잡하며 어떤 특수 성분이 얼마나 증가 되는지 보고 되어 있지 않다. 또한 기존의 구증구포방법은 제조공정 중 건조시 보통 $60^{\circ}C$에서 열풍건조를 하기 때문에 건조시 관리의 부족으로 간혹 벤조피렌에 노출되는 경우가 있다. 본 방법은 새로운 자동 구증구포방법으로 제조시간이 약 2배정도 단축되며 특히 건조시 습열냉각건조를 통하기 때문에 벤조피렌함량이 거의 검출되지 않았다. 또한 사포닌 변환 등은 기존 구증구포방법과 같이 사포닌 변화가 일어나 홍삼에서만 나타나는 Rg3와 기타 효능활성물질 등이 분석되었다. 인삼사포닌의 경우에는 증포횟수가 증가함에 따라 흡수가 어려운 major ginsenoside(Rg1, Re, Rb1, Rc, Rb2 및 Rd)의 함량이 점차적으로 감소되고 대신 흡수가 빠르고 항암활성이 강한 minor ginsenoside (Rh1, 20(S)-Rg2, 20(R)-Rg2, 20(S)-Rg3, 20(R)-Rg3, Rk1 및 Rg5)의 함량이 점차적으로 증가하였다. 특히 diol계 사포닌인 ginsenosides Rb1, Rb2, Rc 및 Rd는 Rg3, Rk1 및 Rg5로 전환되었고, triol계 사포닌인 ginsenosides Rg1 및 Re는 Rh1, Rg2로 전환되었다. 수삼에서의 환원당, 산성다당체 및 총 페놀 화합물 함량은 7회까지 유의적으로 증가하였고 8회부터 점차 감소하는 경향을 보였다. DPPH 라디칼 소거활성은 7회까지 점차적으로 감소하여 $IC_{50}$값이 68% 감소되는 것으로 나타났으며 7회부터 9회까지는 큰 유의적 차이가 없었다. 결론적으로 본 자동 구중구포방법은 기존의 방법과 물질생성은 거의 비슷하지만 시간이 단축되고 벤조피렌 함량이 거의 검출되지 않아 앞으로 고부가가치 인삼산업에 많은 도움을 줄 것으로 생각된다.

We have investigated the effect of MeOH extract of the adventious root culture of Panax ginseng on hyperlipidemic rats induced by fat-rich diet. We also analyzed and compared the content ginsenoisdes of the cultured ginsengs by HPLC. After oral administration of the MeOH extract to hyperlipidemic rats for four weeks, the variables including body weight, cholesterol, HDL, LDL, and triglyceride levels in serum were measured. One of the cultured ginseng roots (CBN3) decreased cholesterol and LDL-cholesterol and increased HDL-cholesterol levels in serum. HPLC analysis demonstrated that CBN3 contains more $Rb_1$ and Rd ginsenosides than any other cultured ginsengs and cultivated ginseng. These results suggest that CBN3 with high contents of $Rb_1$ and Rd may be useful in lowering blood cholesterol.

홍삼으로부터 홍삼알콜 추출물을 제조하고 부산물로 생성된 홍삼추출잔사로부터 한외 여과를 이용하여 홍삼산성다당체(RGAP, red ginseng acidic polysaccharide)를 대량으로 분리할 수 있는 방법을 개발하였다. 본 방법으로 홍삼추출잔사로부터 분리된 RGAP의 수율은 20.9%이었고, RGAP로부터 지표성분인 활성성분(GFP)의 분리수율은 39.4%이었다. 분리된 RGAP는 macrophage에 의한 NO(nitric oxide)를 생성하여 암세포를 사멸시키는 것으로 나타났다. RGAP를 BALB/c 마우스에 복강투여한 후 분리된 복강 macrophage를 P815 암세포(mastocytoma)와 함께 배양하였을 때 배지내의 NO 농도는 대조군에서 4.3 $\mu\textrm{m}$이었으나, RGAP 100, 300 mg/kg 투여군에서는 각각 9.8 및 25.3$\mu\textrm{m}$로 증가하는 경향을 나타내었다. 아울러 암세포인 P8l5세포의 사멸율도 정상대조군일 경우 7.3%이었으나 RGAP 100, 300 mg/kg 투여군에서는 각각 22.7 및 31.8%로 증가하는 경향을 나타내었다. RGAP을 2M의 TFA로 10$0^{\circ}C$에서 1시간 가수분해한 후 당 표준품과 TLC로 비교한 결과 당 표준품과 Rf치 및 발색 색깔이 일치하는 4개의 spot, 즉 rhamnose(Rf 0.78, 노란색 ), glucose(Rf 0.61, 녹색), galactose(Rf 0.56, 녹색), glucuronic acid(Rf 0.36, 황갈색)를 관찰할 수 있었다. 가수분해된 RGAP 분해산물을 Gl(glucose)부터 G7(maltoheptaose)까지의 당류와 함께 TLC를 행한 결과 진한 색상을 나타내는 spot은 Rf 0.56~0.61로 G2(maltose, Rf 0.46) 이상의 단당류(monosaccharide)인 것으로 나타났다. RGAP의 일부 이화학적 특성을 조사한 결과 pH는 4.74, 건조감량은 4.72%, 조단백질 함량은 3.30%, 회분은 4.74%이었고 중금속인 Pb는 2.30 ppm이었다.

Ginseng have been traditionally used for strengthening immunity, providing nutrition and recovering health from fatigue. Recently, pharmaceutical activities of ginseng roots have been proven by many researches, and ginseng has become a world-famous medicinal plant. Ginseng saponin, ginsenoside, is one of the most important secondary metabolite in ginseng which has various pharmacological activities. Many studies have aimed to convert major ginsenosides to the more active minor ginsenoside Rg3 for consumer demand ginseng product. Microbial strain GS514 strain was isolated from soil around ginseng roots for enzymatic preparation of ginsenoside Rg3, which strain shows strong ability of converting ginsenoside Rb1and Rd into Rg3 in the solution with NaCl. The gene encoding a ${\beta}$-glucosidase from this GS514 was cloned and expressed in the BL21 (DE3) strain of Escherichia coli. The recombinant enzyme was purified and characterized. The molecular mass of purified was 87.5 kDa, as determined by SDS-PAGE. The gene sequence revealed significant homology to the family 3 glycoside hydrolases. The purified single enzyme also catalyzed the conversion of ginsenoside Rb1 into Rg3. This target enzyme will be able to produce as much saponin for consumer demand ginseng product. Anti-apoptotic proteins bind with pro-apoptotic proteins to induce apoptosis mechanism. Over expression of these anti-apoptotic proteins lead to several cancers by preventing apoptosis. Docking simulations were performed for anti-apoptotic proteins with several ginsenosides from Panax ginseng. Our finding shows ginsenosides particularly Rg3, Rh2 and Rf have more binding affinity with apoptotic proteins. Further, these docking system of each ginsenosides can be extended to experimental screen system for further brief confirmations of several diseases.

This study was accomplished for the purpose of developing a textile processing ingredient that is harmless to the human body and environment. The research method consists of dyeing cotton textiles by extracting the dye solution from ginseng. Then, chrominance, after treatment, antibacterial ratio and deodorization ratio of cotton fabrics dyed with ginseng extracts were tested and results were examined. The research procedure involved first extracting the dye solution from the ginseng's by-product (fine roots) and then dyeing was effectuated differently according to the test samples temperature and dyeing time requirements. Brightness in all dye substances was lower in pre-mordanting. Beige color could be extracted from pre-mordanted samples. And dark orange from postmordanted samples. Color-festness was high in all samples. Most of samples show a big antibacterial ratio and deodorization ratio. Through this research it has been discovered that, when applied to textiles, Korea's ginseng extract possessed reproducibility features as a natural dye and a possibility to be used in cutting which plays a crucial role in hygienic processing. In addition, by using ginseng's by-product for dyeing processing as the dye solution, efficient application of resources and occurrences of no water waste damages were demonstrated and thus, proved to be environmentally-friendly. Specifically, through this experiment, it was found that saponin, ginseng's special characteristics, possessed excellent antibacterial odor repelling functions to clothing as well as the capability to prevent skin disease.

인삼박의 가용성 추출물을 용출시킨 후 남은 잔여 묵인 인삼박에 상황버섯, 영지버섯, 운지버섯, 표고버섯 균사체를 접종ㆍ배양하여 얻어진 인삼박 균사체 추출액의 전자공여능 및 간암세포(Hep3B)와 고형암(S-180)의 증식에 미치는 영향을 조사하였다. 인삼박 균사체의 전자공여능은 500-10,000ppm 범위에서 농도가 진할수록 높게 나타났으며 운지가 4종류의 균사체 추출물 중 가장 높았다. 간암세포의 형태변화 및 증식 억 제 에 미 치 는 영 향은 에 탄을 추출물이 물 추출물보다 효과적이었으며, 60% 에탄을 추출물 5,000 ppm에서 상황, 영지,운지에 비해 표고가 99.1%로 가장 강한 세포증식억 제 효과를 나타내었다. S-180 고형 암 억제효과는 대조군에 비해 운지가 65%로 가장 컸으며 영지 61%, 표고 56%, 상황 59%의 고형암 억제효과를 나타내었다. 따라서 인삼박을 이용하여 배양된 버섯 균사체가 간암세포와 고형암의 증식 억제에 효과적인 것으로 관찰되므로써 항암물질의 자원으로서 그 활용성이 기대된다고 하겠다.
