본 연구에서는 방사선을 조사한 홍삼 메탄올 추출물의 안전성을 검토하고자 식품의약안전청의 의약품 등의 독성시험기준에 따라 ICR계열의 암수 마우스에 시험물질을 0, 125, 250 및 500 mg/kg/day의 용량으로 90일간 반복경구 투여한 후, 사망률, 일반증상, 체중변화, 혈액 및 혈액생화학적 변화, 부검소견, 조직학적인 변화를 관찰하였다. 시험기간 중 암수 모든 군에서 시험물질 투여에 기인한 일반적인 증상변화는 관찰되지 않았고, 시험물질의 반복 투여로 인한 사망례 역시 관찰되지 않았다. 시험물질의 투여에 기인한 유의적인 체중 감소 또한 나타나지 않았으며, 상기 이외의 육안적인 부검소견에서도 시험물질 투여에 기인한 어떠한 이상소견도 발견되지 않았다. 혈액학적 분석 결과 일부 시험물질 투여군에서 총 백혈구 수 등의 수치가 유의적인 변화를 보였으나, 정상범위 내에서의 변화로 방사선조사에 의해 야기된 독성은 아니었다. 간장과 신장의 조직학적인 관찰에서 시험물질 투여에 의한 변화는 관찰되지 않았다. 따라서 방사선 구조변환 홍삼 추출물을 3개월간 ICR 마우스에 섭취시킨 경우, 시험한 최고 농도인 500 mg/kg/day에서는 독성이 없는 것으로 판명되었다.

The objectives of this study were to investigate the quality of ginseng makgeolli during the fermentation and aging period, and to develop Jeungpyun manufactured by ginseng makgeolli. Four different amounts of ginseng powder (0, 2, 4 and 6 g) were added to the filtered mash which was fermented for 4 days at $24^{\circ}C$ and then aged for 6 days at $4^{\circ}C$ The quality of Jeungpyun batter containing 0, 2, 4 and 6% ginseng during fermentation, and the sensory, color and textural characteristics of ginseng Jeungpyun were analyzed. The pH of jeungpyun batter without ginseng was lower than the other batters. During 4 hours of fermentation of the batter at $30^{\circ}C$, the pH of the batter significantly decreased. The expansion volume of the batter without ginseng increased 4.11 times after 4 hours of fermentation, whereas batters with 2, 4, and 6% ginseng increased 1.70 times. The L value of Jeungpyun decreased by increasing the concentration of ginseng However the a and b values of Jeungpyun significantly increased with an increase in the concentration of ginseng. The results of the sensory evaluation showed that Jeungpyun with 2% ginseng had the highest flavor, taste and overall acceptability scores. In the textural analysis, the hardness of Jeungpyun increased by increasing the concentration of ginseng after 6 days of storage at $20^{\circ}C$. This study showed that Jeunpyun containing 2% ginseng was the optimum addition level.

인삼과 마찬가지로 많은 사포닌을 함유하고 있는 인삼꽃의 이용 가치를 증진시키기 위한 연구의 일환으로 Bacillus subtilis(BS), Lactobacillus plantarum(LP), Lactobacillus casei(LC), Candida utilis(CU), Saccharomyces cerevisiae strain CHY1011(Y1), Saccharomyces cerevisiae strain ZP 541(Y2), 혼합발효(M) 등의 여러 유용 미생물을 이용하여 인삼꽃을 발효시킨 후 미생물별 인삼꽃 발효물에 대한 항산화 활성 변화를 탐색하였다. 총 페놀함량 측정 결과 무발효 추출물은 인삼꽃 발효물에 비해 유의적(p<0.05)으로 높은 값을 보였으며, 발효 균주 중에서는 BS로 발효한 발효물이 가장 높은 값을 나타내었다. DPPH radical 소거활성 및 ABTS radical 소거활성 측정 결과 BS 발효물이 유의적으로 가장 높은 활성을 나타내었으나, FRAP value(10 mg/mL)는 무발효 추출물의 활성이 가장 높게 나왔으며 BS 발효물과는 유의차를 보이지 않았다. 환원력 측정 결과, 대체적으로 무발효 추출물에 비해 미생물 발효물에서 높은 활성을 나타내었으며 LC 발효물이 높은 활성을 나타내었다. 따라서 여러 유용미생물을 이용한 인삼꽃 발효의 경우 Bacillus subtilis를 이용하여 발효할 경우 다른 균주들을 이용하는 것보다 항산화 활성 증진에 우수한 효과를 나타낼 것으로 사료되며 다른 생리활성 증진 효과에 대한 연구가 좀 더 진행되어져야 할 것이다.

This study was divised to observe an Inhibitory effect toward a lipolytic action of toxohormone-L from large root and small root Nepal pseudo ginseng (NPG ; Nepal products) components by water extract and ethanol precipitate in vitro. Toxohormone-L is known to be a lipolytic factor that was partially purified from the ascites fluid of Sarcoma 180-bearing mice and of patients with hepatoma. The inhibitory effect that inhibited the lipolytic action of toxohormone-L by ethanol Precipitate component of large root NPG (mean 55.5%) was higher (mean 1.37 times) than that of water extract component in final reaction concentration of 500 and 1, 000ug/ml, on the other side inhibitory effect of water extract component in small root NPG (mean 55.5%) was higer (mean 1.14 times) than that of ethanol precipitate component. In a way inhibitory effect of precipitate component In large root NPG(47.6%), when final reaction concentration of sample were 1, 000ug/ml, was about 40% lower than that of Korean red ginseng.

In order to develop new bioactive functions ginseng extract, it was studies whether the ginseng extracts on the induction of immunological tolerance In mice. Oral immunologic tolerance was induced by the secondary exposure of egg albumin + alum following gastrointestinal exposure nth egg albumin In mice, and the effect on anti EA antibody in blood, 7 cell subset in spleen were Investigated. The results obtained were as follows. EA group and EA + GE group was capable of conferring tolerance, contained a profound for 5 weeks experimental but saline group restricted to induce tolerance. GE group did not show the activity of tolerance by the first immunogens exposure, but induced the tolerance by the secondary exposure. And also spleen T cells, CD 8+ and CD 4+ were decreased. These results suggested that ginseng may affect the induction of immunological tolerance, which may be associated proliferative response of CD 4+ and CD 8+ in splenocyte.

In order to obtain the basic data for the preparation of yogurt containing ginseng component, the effect of ginseng component on cell growth of Lactobacillus casei YIT 9018 and on lactic acid production were investigated. Initial cell growth and acid production were markedly inhibited by the addition of ethanol extracts in the level of 8% into 15% skim milk. Crude saponin did not show any inhibitory effect on cell growth and acid production, but ether layer fraction showed inhibitory effect. It was thought to be more advantageous to add ginseng extracts after the fermentation of milk than before. The addition of ginseng extract at 8% level into liquid yogurt was most suitable in organoleptic test. Cell viability was not affected by the addition of ethanol extracts up to 8% level during storage of liquid yogurt.

Ginsenosides are responsible for the pharmacological and biological activities of ginseng. In this study, ginsenoside Rh1 and compound K were isolated and purified from fermented ginseng substrate and their anti-allergic effects were assessed in compound 48/80-induced anaphylactic shock model. The fermented ginseng substrate was extracted by methanol and ginsenoside Rh1 and compound K were efficiently purified by preparative high performance liquid chromatography (prep HPLC). Their quality and quantity were analyzed by liquid chromatography-mass spectrometer (LC-MS) and HPLC. Ginsenoside Rh1 showed better anti-allergic effects than compound K in compound 48/80-induced anaphylactic shock model. This study suggested that fermented ginseng extracts with enriched Rh1 may be utilized as a potential biomaterial of functional food for the alleviation of allergic symptoms.

This study was conducted to investigate the antioxidant activities on hydropoic-cultured ginseng roots (HGR) and leaves (HGL). The samples were lyophilized, extracted with 80% ethanol, and then evaluated the antioxidant activities compare with conventional-cultured ginseng. Total polyphenol content of ginseng, HGR, and HGL were 128.85±0.41, 115.74±1.28, and 282.15±5.15 mg/g, respectively. The DPPH radical scavenging activity(IC₅₀) was the highest value of 6.47±0.13 mg/mL in the HGL. The ABTS radical scavenging activity was the highest value of 29.37±0.37 mg AA eq/g in HGL, and ginseng and HGR were 10.23±0.49 and 8.18±0.37 mg AA eq/g, respectively. The reducing power of ginseng, HGR, and HGL were 0.56±0.01, 0.53±0.01, and 0.68±0.01, respectively. Chelating effect was the highest value of 92.65±3.42% in HGL. The results of this study suggest that antioxidant activities in hydropoic-cultured ginseng leaves could have significant health benefits.

Catecholamines are among the first molecules that displayed a kind of response to prolonged or repeated stress. It is well established that long-term stress leads to the induction of catecholamine biosynthetic enzymes such as tyrosine hydroxylase (TH) and dopamine ${\beta}$-hydroxylase (DBH) in adrenal medulla. The aim of the present study was to evaluate the effects of ginseng on TH and DBH mRNA expression. Repeated (2 h daily, 14 days) immobilization stress resulted in a significant increase of TH and DBH mRNA levels in rat adrenal medulla. However, ginseng treatment reversed the stress-induced increase of TH and DBH mRNA expression in the immobilization-stressed rats. Nicotine as a ligand of the nicotinic acetylcholine receptor (nAChR) in adrenal medulla stimulates catecholamine secretion and activates TH and DBH gene expression. Nicotine treatment increased mRNA levels of TH and DBH by 3.3- and 3.1-fold in PC12 cells. The ginseng total saponin exhibited a significant reversal in the nicotine-induced increase of TH and DBH mRNA expression, decreasing the mRNA levels of TH and DBH by 57.2% and 48.9%, respectively in PC12 cells. In conclusion, immobilization stress induced catecholamine biosynthetic enzymes gene expression, while ginseng appeared to restore homeostasis via suppression of TH and DBH gene expression. In part, the regulatory activity in the TH and DBH gene expression of ginseng may account for the anti-stress action produced by ginseng.
