홍미삼을 원료로 홍삼엑기스를 조제할 때 추출용매인 에탄올의 농도가 엑기스 및 조사포닌의 수율과 ginsenoside의 조성에 미치는 영향을 조사하였다. 그 결과 엑기스의 수율은 에탄올의 농도가 증가될수록 감소되는 반면 조사포닌은 증가되었고 이러한 경향은 90%구(區)에서 현저하였다. 그러나 이를 원료삼대비로 보면 일반적인 경향은 증가되나 그 차이가 크지 않았다. 순수사포닌의 수율은 70%와 90%구(區) 사이에 크게 향상되지 않았으나 ginsenoside-$Rb_1.$-$Rb_2$와 -Rd이외의 ginsenoside는 계속 증가되는 경향이 있다. 또한 PD/PT계의 용출된 양의 비는 $1.69{\sim}1.95$의 범위였으며90%, 0% 및 70%구(區)에서 각각 1.69, 1.75, 1.76의 수치를 보여 홍삼엑기스의 수율과 작업성을 고려할 때 조사포닌과 엑기스의 용출율이 높으며 또한 순수사포닌의 용출율이 가장 높은 에탄올 70%가 적합한 것으로 사료되었다.

Saponin is the most pharmaceutical active ingredients of the ginseng plant, it was called "Ginsenoside" which means the Glycoside of ginseng that composed glycosides and aglycones. The human body will absorb the saponin easily if these substrate was decomposed by active microorganism. Fermentation is the most convenient technique to decompose this active ingredients. The purpose of this research was to study the sugar content, pH and acidity development during the ginseng fermentation process. Fresh Korean ginseng and red ginseng extract was used as the main ingredient. The concentrated of pure ginseng extract was added to increase the saponin extract. Furthermore, the mix microbial powder was added as starter to increase the fermentation efficiency. The ginseng was fermented in fermentation chamber at temperature $37^{\circ}C$ during 70 days. In the end of experiment the sugar content was decreased from 24% to 7.65%, The pH was decreased from 6.5 to 3.4, and the acidity level was incresed from 0% to 1.2%.

The effect of ginseng on the reactivity of penile corpus cavernosal smooth muscle strips of rabbits was investigated to support the clinical application of ginseng for the treatment of erectile dysfunction. New Zealand white rabbits were randomly divided into two groups, normal diet group (n=9) and ginseng saponin diet group (n=5). Then, each group was fed normal diet and Korean red ginseng saponin diet (50 mg/kg/day) for 10 weeks. We measured concentration dependent relaxation of corporal smooth muscle to acetylcholine (10-8 M to 10-4M) in organ chamber. The degree of relaxation was expressed as percentage of maximal relaxation obtained by papaverine (10-4M). Dose dependent relaxation of corpus cavernosal smooth muscle to acetylcholine, at the concentration of 10-8 M to 10-4M by half log increment, was 4.06$\pm$0.00, 4.30$\pm$1.30, 5.32$\pm$0.68, 11.64$\pm$1.74, 16.24$\pm$1.61, 23.33$\pm$ 2.29, 26.45$\pm$2.25, 30.43$\pm$2.40 and 33.41 $\pm$2.48 (%), respectively in normal diet group and 9. 83$\pm$4.15, 20.60$\pm$4.62, 24.1815.12, 35.75$\pm$5.71, 43.35$\pm$6.11, 51.30$\pm$6.22, 56.33$\pm$6.22, 54.30$\pm$4.17 and 51.98$\pm$3.92 (Vc), respectively in ginseng group. These data suggest that ginseng enhances ondothelium-dependent acetylcholine-induced relaxation of penile corpus cal.ernosal smooth muscle in rabbits.

Studies were carried out to elucidate the protein stabilizing effect of ginseng. Malate dehydrogenase (EC 1.1.1.37) was used as a protein and the rate constant of the enzyme inactivation was determined under the heat denaturation condition. There was an optimum pH for the enzyme stability, the rate constant of the enzyme inactivation was minimum at BH 8.8. The rate constant was increased at lower and higher pH regions than the optimum pH. The inactivation reaction followed the Arrehnius law and the activation energy was measured as 36.8kcal/mole. The reaction rate was not affected by the enzyme concentration and thus it was assumed to be unimolecular first order reaction. The water extract of red ginseng decreased the rate constant of Malate dehydrogenate under heat inactivation condition to stabilize the enzyme activity. Purified ginseng saponin also stabilized the enzyme against heat inactivation.

본 연구에서는 정관장 홍삼의 물(water) extract, 식용발효 주정 extract 및 홍삼 추출물로부터 분리 제조한 crude saponin을 이용하여 면역반응을 매개하는 수지상세포의 활성 효과에 대하여 알아보았다. 그 결과 홍삼시료 중, crude saponin $100\;{\mu}g/ml$을 처리하였을 때 수지상세포의 세포표면 분자인 MHC class II, CD40, CD80, CD86의 발현이 증가하였으며, phagocytosis는 감소하였다. 또한 홍삼시료를 처리한 수지상세포와 allogeneic T세포를 함께 배양하였을 때, 홍삼시료의 물 extract, 식용발효주정 extract, crude saponin 모두 allogeneic T세포의 증식반응을 유도하였고, IL-2와 $IFN-{\gamma}$의 생산량을 증가시키는 것을 확인하였다. 또한 $CD4^+$ syngeneic T세포와 $CD8^+$ syngeneic T세포의 반응에서도 T세포의 증식반응을 높게 유도하였으며, $CD4^+$ syngeneic T세포에서 IL-2와 $IFN-{\gamma}$의 생산량을 증가시키고, $CD8^+$ syngeneic T세포에서는 $IFN-{\gamma}$ 생산량을 증가시키는 것을 확인하였다. 이상의 결과로 crude saponin의 경우 수지상세포 의 세포표면 공동자극분자의 발현을 유도하고 성숙을 유도함으로써 T세포의 활성을 증진시키는 것으로 생각되며, 물 extract와 식용발효주정 extract는 crude saponin과는 다른 기작으로 T세포 활성화를 유도하는 것을 알 수 있었다. 따라서 실험에 사용한 홍삼시료, 즉 물 extract, 식용발효주정 extract, crude saponin 모두 수지상세포의 활성을 유도하는 물질로써 암항원 특이적 T세포 활성화를 이용한 항암치료에 이용할 수 있는 가능성이 있다고 사료된다.

Red ginseng saponin fraction-A (RGSF-A) contains a high percentage of panaxadiol saponins that were isolated from Korean red ginseng by ultrafiltration. The aim of this study was to elucidate the effects of RGSF-A on the porcine distal left anterior descending (LAD) coronary artery. The relaxant responses to RGSF-A were examined during contractions induced by 100 nM U46619 (9,11-dideoxy-9a,11a-methanoepoxy-prostaglandin F2a), a stable analogue of thromboxane A2. RGSF-A dose-dependently induced biphasic (fast- and slow-) relaxation in the distal LAD coronary artery in the presence of an intact endothelium. The fast-relaxation was quickly achieved in a minute, and then the slow-relaxation was slowly developed and sustained for more than thirty minutes after the administration of RGSF-A. The slow-relaxation had a tendency to be bigger than the fast-relaxation. Fast relaxation induced by RGSF-A was almost blocked by $N_{\omega}$-Nitro-L-arginine methyl ester (L-NAME), a nitric oxide synthase synthase inhibitor and 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one (ODQ), a guanylate cyclase inhibitor. However slow relaxation induced by RGSF-A was only partially inhibited by L-NAME and ODQ. In the endothelium-removed ring, RGSF-A evoked only slowrelaxation to a certain extent. These data suggest that RGSF-A induced both endothelium dependent fast- and slow-relaxation and endothelium independent slow-relaxation in the porcine distal LAD coronary artery. The endothelium dependent fast-relaxation is mediated by the nitric oxide (NO)-cGMP pathway, and the endothelium dependent slow-relaxation is at least partially mediated by the NO-cGMP pathway. However, the endothelium-independent slow-relaxation remains to be elucidated.

홍삼(紅蔘)과 백삼(白蔘)을 실온(室溫)에서 장기보존(長期保存)하였을 때 인삼(人蔘)의 유효약리성분(有效藥理成分)으로 밝혀진 사포닌의 보존년수(保存年數)에 따른 함량변화(含量變化) 및 triol계(系)사포닌과 diol계(系)사포논의 비(比) 즉 PT/PD ratio 등을 조사(調査)하여 다음과 같은 결과(結果)를 얻었다. (1) 보존년수(保存年數)에 따라 총질소(總窒素), 조단백질(粗蛋白質) 및 조지방(粗脂肪)의 함량(含量)은 서서히 감소(減少)하였으나 홍삼(紅蔘)과 백삼(白蔘)사이에는 큰 유의성(有意性)을 인정(認定)할 수 없었다. (2) 총(總)사포닌 함량(含量)은 보존년수(保存年數)에 따라 상당한 감소현상(減少現象)을 나타내었는데 그 정도는 홍삼(紅蔘)보다 백삼(白蔘)이 현저하였다. 3년(年)동안 보존(保存)했을 때 홍삼(紅蔘)은 12%만 감소(減少)한 반면 백삼(白蔘)은 27%나 감소(減少)하였다. (3) HPLC로 정량(定量)한 주성분(主性分)사포닌의 함량(含量)도 보존년수(保存年數)에 따라 감소현상(減少現象)이 뚜렷하였는데 보존기간(保存期間) 3년(年)이 경과(經過)했을 때 홍삼(紅蔘)은 16.8%만이 감소(減少)한 반면 백삼(白蔘)은 같은 기간(期間)에 무려 42.2%가 감소(減少)하였다. (4) 보존년수(保存年數)에 따른 PT/PDratio를 보면 홍삼(紅蔘)은 0.646~0.694%의 범위내에 또 백삼(白蔘)은 0.414~0.428%의 범위내에 있어 홍삼(紅蔘)이 백삼(白蔘)에 비(比)해 PT/PD ratio가 약 50% 정도가 높았다. 이것이 홍삼(紅蔘)의 약리작용(藥理作用)에 깊이 관계(關係)할 것으로 생각된다. (5) 홍삼(紅蔘)과 백삼(白蔘)의 추출액(抽出液)의 가시부(可視部)의 변화(變化)를 보면 백삼(白蔘)이 홍삼(紅蔘)보다 증가폭(增加幅)이 더 크므로 불안정(不安定)함을 알 수 있고, 또 자외부(紫外部)의 변화(變化)를 보면 278nm에서 홍삼(紅蔘)의 흡광도(吸光度)가 백삼(白蔘)보다 크므로 홍삼(紅蔘)의 향미(香味)가 백삼(白蔘)보다 좋음을 알 수 있다.

Acidic polysaccharide from Korean red ginseng was found to inhibit pancreatic lipase activity and cause reduction of plasma triglyceride level after oral administration of corn oil emulsion to rats. Thus acidic polysaccharide may reduce plasma triglyceride through its inhibitory action on pancreatic lipase and successive inhibition of intestinal absorption of fat due to reduction of lipolysis. In the course of this experiment, we found an unknown ninhydrin positive substance in Korean red ginseng. The unknown substance was identified to be arginyl-fructosyl glucose(Arg - Fru - Glc). Coment of this new compound was $5.37\%$ in Korean red ginseng powder. Sucrase and maltase activities in mucous layer of rat jejunum were found to be inhibited by Arg-Fru-Glc. Physiological significance of the new compound was discussed based on these experimental results.

Aerobic cells are normally protected from the damage of free radicals by antioxidative on , zymes such as superoxide dismutase (SOD), catalase, glutathione (GSH) peroxidase, GSH S- transferase and GSH reductase which scavenge free radicals as well as nonenzymatic antioxidants such as ceruloplasmin, albumin and nonprotein-SH including GSH. The effects of each component (ginsenoside $Rb_1$, $Rb_2$, Rc, Rd, Re, $Rb_1$, Rf, $Rh_1$ and $Rh_2$) of red ginseng on the antioxidative enzyme activities were investigated in the liver in order to screen antioxidative components of red ginseng. Ginsenoside $Rb_1$ and Rc showed a tendency to increase GSH peroxidase activity, while ginsenoside Rc significantly decreased Cu,Zn-SOD activity. Especially, ginsenoside $Rh_2$ significantly increased catalase activity. These results suggest that ginsenoside $Rh_2$ is an important active component among total saponins of red ginseng.
