To Identify phenolic components known to exist in Korean ginseng (Panax ginseng C.A. Meyer) by GC/MS, three derivatization methods were employed for their analyses. First, phenolic components in ether soluble acidic fraction prepared from Korean red ginseng powder were taimethylsilylated. Secondly, phenolic acids in the same fraction were esterified with diazomethane followed by trlmethylsilylation. Thirdly, acidic components in ginseng powder were extracted and esterified concurrently by methanolic sulfuric acid, followed by fractionation of phenolic components with Silica Sep-Paka and trimethylsilylatlon. All phenolic components found in ginseng except gen tisic acid were identified by retention times and mass spectrums of standards. Besides, 5 phenolic components including salicyl alcohol and 1-H-indole-2-carboxylic acid were first identified from Korea an red ginseng by GC/MS.

Ginseng (Panax ginseng) is recognized as one of the most valuable medicinal herbs in Asia and it contains diverse phytochemicals that contribute to its pharmacological effects. Although lipids represent a major component of ginseng, ginseng lipids are still far from being fully explored. This review is focused on ginseng lipid components and methodologies of their analysis. The ginseng lipid compounds were categorized according to the structural features of each lipid class. This basic information on ginseng lipid components and the analysis methods will be applicable to authentification or quality control of ginseng products, and development of lipid-based pharmaceuticals and nutraceuticals from ginseng.

To obtain the safety evaluation of the ginseng, residues of heavy metals in culture environment of ginseng on Punggi and Sangju, Kyeongbuk are surveyed. The concentration for component of ginseng on Punggi and Sangju were 14.12mg/kg and 15.74mg/kg, respectively. The concentration for general component such as crude fiber, ash, crude lipid, crude protein, carbohydrate, of ginseng were coincided between Punggi and Sangju. The concentration for As, Pb, Cd, and Hg in soil on Punggi were 14.24 ppb, 43.13 ppb, 8.73 ppb and 0.82 ppb, respectively. The concentration for As, Pb, Cd, and Hg in soil on Sangju were 19.20 ppb, 54.82 ppb, 15.90 ppb and 1.04, respectively. Residual heavy metals are not polluted in the soil with culture ginseng on Punggi and Sangju. The concentration for As, Pb, Cd, and Hg with ginseng on Punggi were 29.30ppb, 21.78 ppb, 1.32 ppb and 2.72 ppb, respectively. The concentration for As, Pb, Cd, and Hg with ginseng on Sangju were 3.22 ppb, 24.43 ppb, 1.44 ppb and 4.74 ppb, respectively. Also the detection concentration for As, Pb, Cd, and Hg in ginseng were also lower than the Korea Food & Drug Administration advisory level for heavy metal in herbal medicines. Residual heavy metals are not polluted in the ginseng on Punggi and Sangju at Kyeongbuk, Korea.

사포닌은 인삼의 약리작용을 매개하는 인삼의 주요 성분이다. 인삼의 뿌리는 여러 가지 독소에 의하여 유발되는 독성에 대한 보호작용이 있는 것으로 알려지고 있다. 본 연구에서는 세균독소(lipopolysaccharides)에 의하여 유도되는 종양괴사인자 생성에 미치는 인삼 사포닌의 영향을 살펴보았다. 독소를 투여한 생쥐의 혈청중 종양괴사인자의 농도는 상승하는데, 인삼 사포닌 50 mg/kg을 독소와 함께 복강으로 투여한 경우는 독소만 투여하였을 때에 비하여 혈정 중 종양괴사인자의 농도가 현저히 낮았다. 이러한 인삼 사포닌의 효과는 사포닌의 용량, 투여방법과 투여시간에 영향을 받았는데, 사포닌을 경구로 투여하거나 독소를 주사한 후에 투여하였을 때에는 종양괴사인자 농도에 유의성 있는 차이를 나타내지 않았다. 이러한 결과는 인삼이 간 손상에 대한 보호작용이 있을 가능성을 시사하였고, 사포닌이 이러한 인삼의 보호효과를 매개하는 활성 성분임을 의미한다.

Identification and changes of physiologically active substances during chilling storage of dehisced ginseng (Panax ginseng C. A. Meyer) seeds were analyzed using various preparatory separation methods and purification columns; Dowex 50W and silica gel columns. Seven components with Rf values of 0.20, 0.40, 0.58, 0.66, and 0.70 In solvent system, $CHCl_3$:MeOH=3:1 (v/v), Rf values of 0. 63 and 0.74 in solvent system, $CHCl_3$:MeOH:$H_2O$:=7:3:1 (v/v) were obtained through Dowex 50W and silica gel column chromatographies. Two components with Rf values of 0.20 and 0.63 in the all chilling treatments were detected in the extract obtained through both chromatographies, and only the former component was gradually increased till 4 weeks of chilling storage and then rapidly decreased from 8 to 16 weeks. UV spectra of Rf values of 0.66 and 0.56 were similar to that of cytokinin, but their physiological activities were not found. Rf values of 0.20 showed activity by radish cotyledon expansion bioassay. The component with Rf value of 0.20 was revealed to have a naphthalene in the proposed chemical structure by various NMR techniques.

Polysaccharide contents in Panax ginseng roots were evaluated by a spectrophotometry, utilizing the complex formation of ginseng polysaccharide with alcian blue dye in 50 mM ammonium biphos-phate, pH 4.2. The polysaccharide content in red ginseng was about three times higher than that in fresh ginseng when both were extracted with water, and increased about two times when red ginseng was extracted with an alkaline solution. The determination of polysaccharide in various parts of ginseng revealed that main roots contained the component more than fine roots. Fresh ginseng sections stained by the dye showed polysaccharide mainly was found in cortex and combium but not in epidermis.

Total polysaccharide contents in Panax ginseng roots were evaluated by a spectrophotometry, utilizing the complex formation of ginseng polysaccharide with alcian blue dye in 50 mM ammonium biphosphate, pH 4.2. The total polysaccharide content in red ginseng was about three times higher than that in fresh ginseng when both were extracted with water, and was increased about two times when red ginseng was extracted with an alkaline solution. The determination of total polysaccharide in various parts of ginseng revealed that main roots contained the component more than fine roots. Fresh ginseng sections stained by the dye showed polysaccharide mainly found in cortex and cambium but not in epidermis. Pattern-analysis on total and acidic polysaccharides from fresh and red ginsengs exhibited that the chemical compositions of the polysaccharides extracted from both ginsengs quite differed from each other.

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.

홍삼의 물 추출물, 알코올 추출물, 지용성 추출물, 총 사포닌, PD 및 PT 각 홍삼 추출물을 생리식염수에 녹여 50mg/kg/0.1ml용량으로 4주령 수컷 생쥐에게 15일간 경구투여 하여 생쥐 간으로부터 항산화 효소(GPX)의 활성도 변화와 GSH, GSSG 및 MDA의 함량 변화에 미치는 영향을 조사하였다. GPX의 활성도는 PD, PTTS순으로 활성도가 높은 것으로 조사되었으며, 항산화 물질인 환원형 GSH 또한 같은 순으로 증가하는 것으로 사되었다. 한편 GSSG 함량은 지용성 추출물, PD, 알코올 추출물 순으로 감소하는 것으로 조사되었다. 동물조직세포내의 산화환원반응과 해독작용상태의 평가에 중요한 GSSG/total GSH비율은 지용성 추출물, PD, 총 사포닌 순으로 감소하는 것으로 조사되었다. 활성 산소에 의해 생성된 지질과산화의 최종산물인 MDA의 함량은 GSSG/total GSH 비율의 조사 결과와 비슷한 경향을 보였다 이와 같은 결과를 종합하여 볼 때 항산화 효소 활성과 항산화 물질 활성 증대를 강화시키는 홍삼 성분으로는 지용성 추출물, PD 및 총 사포닌인 것으로 조사되었으며, 이러한 성분들이 산화적 손상에 대한 방어기전 향상에 좋은 것으로 생각된다.
