The investigation of UV absorbing compounds in saponin fraction of Pnm.1. Kiairnk root was carried out by thin layer chromatography, semipreparative HVLC. l3C, 1H-NMR, mass spectrometry and chemical characteristics in searching plant for growth regulatony substances such as phenolic glycoside. Drying of fresh ginseng at 15 $^{\circ}C$ decreased not only number but also size of UV absorbing sports on TLC. One of the relatively large spots in fresh ginseng was isolated and identified as adenosine, which is subjected for growth stimulatory activity Detection of phenolic glycosides failed in dried root bolt was highly probable in fresh ginseng even with the insufficient amount of sample.

The effects of treating bovine heart mitochondria with potassium chloride and surfactants such as digitonin and n-dodecy-$\beta$-maltoside (DMS) including plant saponins on extracting cytochrome c were examined. The spectra given by the cytochrome c-containing solutions from the extraction were inspected to ascertain whether ginseng and bellflower saponins could be used instead of the generally- employed surfactants of digitonin and DMS. These studies implied that the effect of ginseng saponins is superior to that of digitonin but inferior to that of DMS, and give rise to the idea of substitutional property of ginseng saponins for the widely-employed surfactants in the extraction of mitochondria intermembrane cytochrome c. The substitution for the solubilizing surfactants by bellflower saponins could, however, not presumably be anticipated; while ginseng saponin mixture are a suitable substitute.

더덕 (Codonopsis lanceolata)의 자엽기의 체세포배 는 생장조절제 를 함유하지 않은 MS고체배지에 배양하였을 때 완전한 식물체로 분화되었다. 체세포배로부터 줄기 재분화에는 2% sucrose가, 뿌리의 분화에는 8% sucrose가 가장 좋았다. 줄기의 생장은 2% sucrose가, 뿌리의 생장은 4% sucrose 농도에서 가장 좋았다. 자연산 더덕뿌리, 재분화 개체의 뿌리, 배발생 캘러스, 비배발생 캘러스에서의 saponin계 물질의 함량을 HPLC로 조사한 결과 각 조직간의 물질 함량은 커다란 차이를 보였으며, 고농도의 sucrose 함유 배지에서 재분화된 뿌리의 saponin계 물질의 함량은 자연산뿌리와 비슷하였다. 세포분화가 진행됨에 따라 saponin계 물질의 함량은 급격히 감소하였다. 이러한 결과는 식물의 유용물질 생산에 효율적으로 활용될 수 있을 것이다.

This study was conducted to elucidate the effects of light intensity using polyethylene (p.E) net shading on the specific gravity, red ginseng quality, sugar and saponin contents of ginseng root. The specific gravity significantly increased in the ginseng roots grown under the P.E net shading as compared with that of common straw shading. The red ginseng quality under the P.E net shading was improved in order of 10, 5, 15, 20, 30% of light intensity and the inside cavity and inside white part decreased remarkably as compared with those of common straw shading. The ginseng roots grown under the P.E net shading at 10% and 15% light intensity showed a significant increase in the total sugar content but a significant decrease in the reducing sugar content at 15% light intensity as compared with those of common straw shading. The amount of total saponin of ginseng roots was increased under the P.E net shading at high light intensity as compared with that of common straw shading and the ginseng roots grown under the P.E net shading at 10% light intensity showed an increase in the diol group saponin but the ratio of PT/PD was decreased. Extract contents of ginseng root under the P.E net shading was higher than those of common straw shading and the roots grown under the P.E net shading at 15% and 20% light intensity resulted in a remarkable increase in extract contents.

Background: Cultivation of medicinal crops, which synthesize hundreds of substances for curative functions, was focused on the synthesis of secondary metabolites rather than biomass accumulation. Nutrition is an important restrict factor for plant growth and secondary metabolites, but little attention has been given to the plasticity of nutrient uptake and secondary metabolites synthesis response to soil nitrogen (N) change. Methods: Two year-field experiments of Sanqi (Panax notoginseng), which can synthesize a high level of saponin in cells, were conducted to study the effects of N application on the temporal dynamics of biomass, nutrient absorption, root architecture and the relationships between these parameters and saponin synthesis. Results: Increasing N fertilizer rates could improve the dry matter yields and nutrient absorption ability through increasing the maximum daily growth (or nutrient uptake) rate. Under suitable N level (225 kg/ha N), Sanqi restricted the root length and surface and enhanced the root diameter and N uptake rate per root length (NURI) to promote nutrient absorption, but the opposite status of Sanqi root architecture and NURI was found when soil N was deficient. Furthermore, increasing N rates could promote the accumulation of saponin in roots through improving the NURI, which showed a significant positive relationship with the content of saponin in the taproots. Conclusion: Appropriate N fertilizer rates could optimize both root architecture and nutrient uptake efficiency, then promote both the accumulation of dry matter and the synthesis of saponins.

최근 식품 및 천연 물질로부터 항산화 작용이 있는 생리 활성 물질을 찾고자 하는 연구가 활발하게 진행되고 있다. 본 연구에서는 우리나라를 비롯하여 동양권에서 전통적으로 자양강장을 목적으로 많이 사용해온 인삼을 압출 성형 기술에 의해 가공한 후 80% 에탄올로 추출하고 감압 농축한 에탄올엑기스와 이를 에테르를 이용하여 지방 성분을 제거한 후 수포화 부탄올 처리한 부탄올 분획과 물 분획을 얻었다. 인삼과 압출 성형 인삼의 부탄올 층을 각각 고속 액체 크로마토그라피에 의해 인삼 사포닌 함량을 측정하였다. 실험 결과 압출성형 인삼이 대조 인삼에 비해 ginsenoside Rg1의 경우 약 2.2배, Re의 경우 약 2.3배, Rc의 경우 약 1.2배, Rb2의 경우 약 1.3배, Rd의 경우 약 2.2배의 사포닌 함량이 증가하는 결과를 보였다. 또한, ORAC 방법에 의한 항산화 활성 실험 결과, 압출 성형 인삼의 경우 인삼 중의 여러 유효 성분이 많이 함유되어 있는 80% 에탄올 추출분 획과 일반적으로 사포닌 성분을 많이 함유한 부탄올 분획은 물론이고, 사포닌 함량이 거의 없는 수층 분획 모두에서 대조 인삼의 분획들에 비해 유의성 있는 증가 (0.05

In order to increase the production of ginseng, a cultural experiment was carried out under different types of natural forest condition. Seedlings were transplanted with three spacing (70,90 and plants per 1.62m2) under the broad leaved, needle and mixed forest. The obtained results are as follows. 1 Growth of aerial part of ginseng plant. 1) Vegetative growth under forest condition of very poor as compared with ordinary cultivation, but there was no significant in number of leaf and teasel. 2) Stem diameter and stem length under the different forest types were a little difference. However petiole length and number of leafet showed an increasing trend in broad leaved forest as compared with other forest types. 3) The withering date of aerial part of ginseng plant in the needle forest was later than of others. 2. Fresh weight of ginseng root per plant was decreasing in the order of broad leaved forest, needle and mixed forest, needle and sized forest respectively. However the root weight was much smaller than that of ordinary cultivated one. 3. No big difference was observed in the growth of both aerial and root among the planting density 4. Nitrogen content in ginseng root under forest was lower, but calcium content In root was higher than that of ordinary one. 5. Fat and fiber content of ginseng root under forest showed higher than that of ordinary one. 6. The saponin content of ginseng root grown under forest condition was higher than that of ordinary ginseng root. According to high performance liquid chromatogram of saponin, only difference from ordinary cultivated ginseng root was that ginsenoside Re showed higher peak than ginsenoside Rg1.
