인삼부정근 배양에서 MeJA 처리가 부정근내 진세노사이드와 페놀화합물의 생산에 미치는 영향과 이러한 이차대사 산물의 증가에 따른 인삼부정근의 항산화활성의 효과를 조사하였다. 다양한 농도의 MeJA를 인삼부정근에 처리한 결과, $100\;{\mu}M$ MeJA에서 부정근내 진세노사이드의 생산은 26.6 mg/g dry wt로 대조구보다 약 8배 이상 생산하는 것으로 나타났다. 하지만, MeJA의 처리는 부정근의 생장을 감소시키는 것으로 나타났다. 페놀화합물의 생산 역시 MeJA처리에 의하여 증가되는 경향을 나타냈으며 $50\;{\mu}M$ MeJA에서 0.38 mg/g dry wt로 대조구에 비하여 약 3배 이상 증가한 것으로 나타났다. 이러한 MeJA의 처리효과는 조건배지 (CM)를 이용하는 것이 신선배지 (FM)를 이용하는 것보다 유리한 것으로 나타났다. 배지성분이 결핍된 조건배지에서의 진세노사이드 생산은 신선배지에서 보다 약 1.7배가 증가한 것으로 나타났으며, 페놀화합물 역시 조건배지에서약 1.2배가 증가한 것으로 나타났다. 이러한 MeJA 처리에 의한 진세노사이드와 페놀화합물의 증가는 결과적으로 인삼부정근의 항상화활성을 무처리구인 대조구에 비해서 약 72%이상 증가시키는 것으로 나타났다.

북미가 원산지인 왜생삼(Panax trifolius L.)은 인삼속(오가과)에 속하며 카나다 남부에서 북미에 걸쳐 서식한다. 왜생삼 잎에서 4종류의 프라보느이드와 5종류의 진세노사이드로 확인된 총 9종류의 화합물을 분리하였다. 2종류의 진세노사이드로 확인된 총 9종류의 화합물을 분리하였다. 2종류의 프라보노이드는 kaempferol-3,7-dirhamnoside와 kaempferol-3-gluco-7rhamnoside로 각각 확인되었다. 4종류의 진세노사이드는 각각 notoginsenoside-Fe, ginsenoside-Rd, ginsenoside-Rc와 ginsenoside-$Rb_3$로 확인되었으며, 이들 왜생삼의 ginsenoside 공통된 골격구조는 (20S)-protopanaxadiol인 것으로 밝혀졌다. 프라보노이드와 진세노사드의 동정은 왜생삼의 뿌리, 줄기, 잎, 꽃과 열매에서 추출하여 2차원 박층 그로마토그라피(2D-TLC)와 고압 액체크로마토그라피(HPLC)로 하였다. 왜생삼과 근연종인 고려인삼(Panax ginseng C.A. Meyer)및 미국삼(Panx quinquefolium L.)의 뿌리, 줄기, 잎, 꽃과 열매에서 추출한 프라보노이드와 진세노시드의 정량은 고압 액체크로마토그래피 만을 사용하여 분석하였다. 화합물 1,3과 4로 명명한 kaempferol 유도체인 프라보노이드 3가지는 왜생삼의 뿌리에 $10.8\%,\;2.8\%$와 $8.4\%$가 각기 함유되어 있었으나 고려인삼과 미국삼에서는 함유되어 있지 않았다. 오가과 인삼속식물 뿌리에서 프라보노이드가 확인, 동정된 것은 이것이 처음이다.

"Korea ginseng (Panax ginseng C.A Meyer) is an important medicinal plant. Its root has been used as an herbal medicine that provides resistance to stress and disease, and prevents exhaustion since the ancient time. Ginsenosides, glycosylated triterpene (saponin), are considered to be the main active compounds of the ginseng root. Despite of considerable commercial interests of ginsenosides, very little is known about the genes and their biochemical pathways for ginsenoside biosynthesis. This work will focus on the identification of genes involved in ginsenoside biosynthesis and the dissection of ginsenoside biosynthetic pathway using a functional genomics tool. Expression sequence tags (ESTs) provide a valuable tool to discovery the genes in secondary metabolite biosynthesis. We generated over 21,155 ginseng ESTs that is now sufficient to facilitate discovering the genes involved in ginsenoside biosynthesis such as oxidosqualene cyclase(OSC), cytochrome P450 and glycosyltransferase. With ESTs information, microarray technology will be used for the analysis of gene expression, and the identification of genes including transcription factors expressed in tissues under given experimental condition. Heterogous system such as yeast and plants will allow us to do the functional analysis. And selected ginseng hairy root which show variation in ginsenoside production will be used as a material for functional analysis of candidate gene. Functional genomics approach will successfully accelerate gene discovery, and also provide promises of metabolic engineering for the ginsenoside production."

Ginseng (the root of Panax ginseng C. A. MEYER, Araliaceae) has been used for traditional medicine in China, Korea, Japan and other Asian countries for the treatment of various diseases including psychiatric and neurologic diseases as well as diabetes mellitus. So far, ginseng saponins (ginsenosides) have been regarded as the principal components responsible for the pharmacological activities of ginseng. Ginsenosides are glycosides containing an aglycone (protopanaxadiol or protopanaxatriol) with a dammarane skeleton and have been shown to possess various biological activities including the enhancement of cholesterol biosynthesis, stimulation of serum protein synthesis, immuno- modulatory effects and anti-inflammatory activity. Several studies using ginsenosides have also reported anti-tumor effects, particularly the inhibition of tumor-induced angiogenesis, tumor invasion and metastasis, and the control of phenotypic expression and differentiation of tumor cells.

Tissue culture of the roots of Panax ginseng was carried out to enhance the production of ginseng callus as well as to increase its contents of ginsenosides. A long cylinder type callus mass was formed when cultured IK callus by rotary shaking culture method, the growth ratio of the callus being 7.71 which was approximately 4 fold higher than those obtained by other culture methods. Ginsenosides $Rg_1$, Re and $Rb_1$ could be detected from the callus mass by TLC, however, their total contents were revealed to be approximately 9% compared to that of the fresh ginseng root equivalent by HPLC analysis,.

Ginseng root explants and calli induced from selected cell lines were cultured on modified Murashige and Skoog's media supplemented with different concentrations of organic or inorganic compounds and plant growth requlators to clarify the effects of chemical composition and plant growth regulators in the medium on the growth of ginseng calli and the production of ginseng saponin. For optimum growth of calli, the concentrations of 2, 4-D and sucrose were the range of 1 to 3 mg/${\ell}$l and 1 to $3\%,$ respectively. And it was clarified that sucrose, nitrogen, phosphate, calcium, magmesian plant growth regulators and their concentrations influcenced the relative biosynthesis of saponin in tissue cultures of Panax ginseng. The patterns of ginsenosides, pharmacologically useful component, were different among the cell lines and contents of ginsenosides were much higher in selected cell lines than in original cell line.

Background: The root and rhizome are historically and officially utilized medicinal parts of Panax notoginseng (PN) (Burk.) F. H. Chen, which in raw and steamed forms are used differently in practice. Methods: To investigate the differences in chemical composition and bioactivities of PN root and rhizome between raw and steamed forms, high-performance liquid chromatography analyses and pharmacologic effects evaluated by tests of anticoagulation, antioxidation, hemostasis, antiinflammation, and hematopoiesis were combined. Results: With the duration of steaming time, the contents of ginsenosides $Rg_1$, Re, $Rb_1$, Rd, and notoginsenoside $R_1$ in PN were decreased, while those of ginsenosides $Rh_1$, $20(S)-Rg_3$, $20(R)-Rg_3$, $Rh_4$, and $Rk_3$ were increased gradually. Raw PN samples steamed for 6 h at $120^{\circ}C$ with stable levels of most constituents were used for the subsequent study of bioeffects. Raw PN showed better hemostasis, anticoagulation, and antiinflammation effects, while steamed PN exhibited stronger antioxidation and hematopoiesis activities. For different parts of PN, contents of saponins in PN rhizome were generally higher than those in the root, which could be related to the stronger bioactivities of rhizome compared with the same form of PN root. Conclusion: This study provides basic information about the chemical and bioactive comparison of PN root and rhizome in both raw and steamed forms, indicating that the change of saponins may have a key role in different properties of raw and steamed PN.

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 ($38.6{\pm}3.2kg$), and dairy milk yield ($2.85{\pm}1.2kg$), 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.

4년근 미국 인삼을 재료로 미국 North Carolina 소재 인삼포에서 대조군과 부초처리군으로 나누어 재배 시험을 수행하였다. 토양 산도(pH 4.4, 5.5, 6.5) 토양 인산(19, 89.232 ppm) 및 부초처리 (밀짚, 솔잎, 포프라나무 껍질 소나무 껍질 등을 상면에 피복) 재배가 개별 진세노사이드 함량에 미치는 영향을 조사했다. 각 시험구에서 재배한 인삼옆과 인삼근 조직을 H-PLC를 이용하여 5가지 진세노사이드($Rg_{1}$, Rd. Re, $Rb_{2},\;A_{1}$) 함량을 분석하였다. 각 피복재료중에서 떡갈나무 껍질로 피복 재배한 시험구가 인삼 생육 및 진세노사이드 함량이 전반적으로 좋은 경향을 보였다.
