Ginseng has been widely used for the management of anxiety and emotional instability, but there is little experimental evidence supporting these clinical applications. The anxiolytic-like effect of ginseng saponin and polysaccharide fractions of white (WG) and red ginsengs (RG) was investigated using the elevated plus-maze test. The saponin (SF) and polysaccharide (PF) fractions were orally administered to male ICR mice for 3 days and behavioral test for the anxiolytic activity were performed. SF significantly increased the time-spent open arms and number into the in the open arm entries. However, PF weakly increased the time-spent in the open arms, but did not increase number into the open ann entries. The WG showed more potent anxiolytic-like effect than that of RG. The anxiolytic-like activities were antagonized by flumazenil, but not by esmolol. These findings suggest the saponin fractions of WG and RG promote the anxiolytic-like activity by antagonizing GABN/benzodiazepine receptors in mice.

In order to investigate the immunomodulatory mechanism of white ginseng, the effects of total saponin of Ginsenoside Rb$_2$component on the phagocytosis and reactive oxygen intermediate(ROI) production of mouse peritoneal macrophages were studied. Both phagocytosis assay nitrobluetetrazolium reduction test showed 20$\mu\textrm{g}$/ml concentration of total saponin significantly increased the activity of phagocytosis and production of ROI. Also cytokine gene expression of the macrophages was analyzed using reverse transcription polymerase chain reaction. In the RT-PCR assay, 20$\mu\textrm{g}$/ml concentration of either total saponin or Ginsenoside Rb$_2$increased IL-1 and TNF expression of the macrophages.

식물조직배양기술을 이용하여 사포닌 함량이 높은 인삼 root를 생산하고자, 인삼 root의 생장과 사포닌생산에 미치는 배지와 식물생장조절물질의 영향을 조사하였다. 인삼 root를 여러 종류의 배지에 배양하였을 때, 인삼 root의 생장과 사포닌 생산은 SH배지에서 가장 우수하였고, SH배지에 배양시, 접종후 약 10일후에 생체중량이 초기접종량의 2배가 되었다. 각 배지별로 배양한 인삼 root의 진세노사이드 패턴과 함량은 다소 차이가 있었는데, SH배지와 White배지에서 성장한 인삼 root의 총진세노사이드 함량이 가장 높았다. 생장조절물질에 있어서는 4.0mg/L NAA를 함유한 SH배지에서 성장한 인삼 root의 생장이 가장 우수하였고, 사포닌 함량은 0.5mg/L BAP 처리구에서 가장 높았다. 이러한 결과들은 인삼 root 배양에 의해 사포닌을 단기간에 생산할 수 있는 가능성을 제시하고 있다.

수천 년 동안 전통적 약제로 사용되어온 고려인삼은 중추신경계의 항상성을 유지하고 면역기능을 강화하는 효능을 나타내는 것으로 알려져 있다. 신경계질환의 진행이 대부분 염증 또는 면역반응을 수반하며, 이로 인하여 손상된 신경세포의 수복과정에 교세포 기원의 매개물질들이 기여하므로, 교세포에서의 cytokine 및 NO생성에 대한 연구는 신경기능과 신경면역기능의 조절 뿐 아니라 신경계 질환에 대한 연구의 초석이라고 할 수 있다. 따라서 본 연구에서는 고려인삼의 신경면역 및 염증반응 조절효과에 대하여 연구하고자 하였으며, 이를 위하여 흰쥐 대뇌피질의 교세포를 일차배양하며 고려인삼사포닌 분획을 처치하여 TNF-$\alpha$, IL-1$\beta$, 및 NO의 생성변동을 연구하였다. 백삼 사포닌은 50-500$\mu\textrm{g}$/ml 용량에서 TNF-$\alpha$와 IL-1$\beta$ 생성을 증가시켰으며, 미세교세포에서 iNOS 발현 및 NO생성을 유도하였고 성상세포의 stellation을 초래하였다. 특히 백삼사포닌 50-100 $\mu\textrm{g}$/ml는 세포독성을 거의 나타내지 않았으므로 이들 용량에 의한 교세포의 적절한 활성화가 중추신경계 면역기능 증가 및 염증반응 조절에 기여할 것으로 생각된다.

Ginseng components were examined for their ability to modify immunotoxicity of cyclophosphamide. Ginseng polysaccharide fraction (FO, 300 mg/kg) inhibited decreases in the ratio of spleen to body weight, white blood cells (WBC) count and the number of plaque forming cells (PFC) induced by cyclophosphamide (50 mg/kg, i.p.), and increased these variables in normal mice. Ginseng saponin fraction (50 mg/kg) showed to increase hemoglobin content as well as the number of PFC/spleen in normal mice. on the other hand, Panaxytriol (20 mg/kg) Prevented decrease in mc count by cyclophos phamide. Neither saponin fraction nor panaxytriol had any significant effect on the number of PFC and antibody titers in cyclophosphamide-treated mice. These results suggest that ginseng polysaccharine fraction may reduce the immunotoxicity of cyclophosphamide and may be effective in stimulating immune function in normal mice.

In order to investigate the optimal drying condition of white ginseng by using bulk air drier(130 x 62 x 65cm), drying curves, diffusion coefficient at various drying temperature, the energy of activation, variation of color intensity and chemical components during drying of white ginseng were studied. Fick's second low of diffusion for diffusion out of spheres was successfully applied to describe the drying of white ginseng. It was found that the diffusion coefficient of water was 2.2x107, 9.0x107 cm2/sec at drying temperature 4$0^{\circ}C$, 55$^{\circ}C$, respectively. An Arrhenius type temperature dependency of moisture diffusivity was found, the energy of activation being 18.8 Kcal/g mol. Color intensity of white ginseng dried at various drying temperature was increased with an increase in drying temperature. The contents of crude protein, reducing sugar and crude saponin during drying of white ginseng were gradually decreased as increasing of drying time. And with the sensory evaluation by multiple comparison difference analysis, the optimal drying temperature of white ginseng was between 45$^{\circ}C$ and 5$0^{\circ}C$.

Panax ginseng C.A. Meyer(Araliaceae) has been traditionally used as an expensive and precious medicine in oriental countries for more than 5, 000 years. Ginseng saponin isolated from the root of Panax ginseng have been regarded as the main effective components responsible for the pharmacological and biological activities. Such as antiaging effects. antidiabetic effects anticancer effects. Protection against physical and chemical stress. Analgesic and antipyretic effects. Effects on the central nervous system, tranquilizing action and others. Thirty kinds of ginsenosides have been so far isolated from ginseng saponin and their chemical structures have been elucidated since 1960's. Among which protopanaxadiol type is 19 kinds. protopanaxatriol type. 10 kinds and oleanane type, one. Since ginsenosides are generally labile under acidic conditions ordinary acid hydrolysis is always accompanied by many side reactions, such as epimerization. hydroxylation and cyclization of side chain of the sapogenins Especially. it is well known that C-20 glycosyl linkage of ginsenoside was hydrolysed on heating with acetic acid to give an equilibrated mixture of 20(S) and 20(R) epimers. And also, the chemical transformations of the secondary metabolites have appeared during the steaming process to prepare red ginseng. Indicating demalonylation of malonyl ginsenosides, elimination of glycosyl residue at C-20 and isomerization of hydroxyl configuration at C-20. But these studies have not provided a comprehensive picture in explaning how these ginsenosides showed val'iotas pharmacological activities of ginseng. Though some of them have been involved in the mechanism of pharmacological actions. Recently, non-saponin components have received a great deal of attention for their antioxidant, anticancer antidiabetic, immunomodulating. anticomplementary activities and so on. To meet the demand for such wide applications, studies on the non-saponin components play an important role in providing a good evidence of pharmacological and biol ogical activities. Among the non-saponin constituents of Korean ginseng, polyacetylenes, phenols. Sesquiterpenes, alkaloids. polysaccharides oligosaccharides, oligopeptides and aminoglycosides together with ginsenosides of terrestrial part are mainly described.

부패한 인삼(人蔘) 및 인삼제품(人蔘製品)에서 분리된 3종의 미생물(微生物)을 인삼 crude saponin농도를 달리한 czapek 배지 등에 배양하여 그 배양 미생물에 의한 ginsenoside의 pattern과 함량변화를 조사하였다. Aspergillus sp.는 0.3%에서 최대의 균체량을 9일에서 나타냈으며 Penicillium sp. -A와 B도 같은 경향이었고, 1.0%에서는 대조군보다 균체 증가량이 낮았다. 인삼 saponin pattern의 변화는 Aspergillus sp.를 6일 배양하였을 때 0.3% 첨가한 경우 diol계 saponin이 완전히 분해되었고 1% 첨가 배양에서는 상대적인 함량의 차이가 있었다. Penicillium sp. -A는 saponin pattern 변화에 영향을 주지 않았으며, Penicillium sp. -B는 배양 12일에서 diol계 saponin이 상소하였다. 또한 수삼배지(水蔘培地)및 건삼배지(乾蔘培地)에서 부패미생물은 인삼(人蔘) crude saponin 함량(含量)을 감소시키었다.
