In order to investigate the optimal conditions which affects to extraction of ginseng extract and saponin in ginseng extract, experiment was carried out varing with ethanol percentage, extraction time, temperature, sol$.$vent and Plant Parts. The results art as follows: 1. The amounts of ginseng saponin was increased according to increanation of ethanol Percentage while the amounts of ginseng extract was decreased. 2. The amounts of ginseng extract was increased as the prolongation of extraction time, on the ether hand, ginseng saponin contents increased lentil 40hr. and decreased after that. 3. By the raise of extract temperature, both of the amounts of ginseng saponin and ginseng extract was increased two times and four times. respectively. 4. The total amounts ginseng extract was obtained 22.86u when the water used as the extraction solvent, 11.28% on ethanol and 11.04U on methanol, in the order. and the saponin contents gained when the extraction solvents of water, methanol and ethanol 7.47%, 12.36% and 12.77%, respectively. 5. It showed 9.23% of ginseng extract in epidermis and 8.4% of ginseng saponin in tail Part of raw ginseng and in the case of dried ginseng, ginseng extract and saponin showed the most amounts in epidermis of 18.28% and 19.35%, respectively. 6. The ratio of panaxadiol and panaxatriol contents of ginseng saponin was almost same when it was extracted varing with ethanol percentage and extraction time (duration), and the more alcohol percentage and the longer extraction time increased, the more fractional content of ginseng saponin was extracted.

This study was aimed (i) to develop an effective method for the purification of ginsenosides for industrial use and (ii) to compare the distribution of ginsenosides in cultured wild ginseng roots (adventitious root culture of Panax ginseng) with those of red ginseng (steamed ginseng) and white ginseng (air-dried ginseng). The crude extracts of cultured wild ginseng roots, red ginseng, and white ginseng were obtained by using a 75% ethanol extraction combined with ultrasonication. This was followed sequentially by AB-8 macroporous adsorption chromatography, Amberlite IRA 900 Cl anion-exchange chromatography, and Amberlite XAD16 adsorption chromatography for further purification. The contents of total ginsenosides were increased from 4.1%, 12.1%, and 11.3% in the crude extracts of cultured wild ginseng roots, red ginseng, and white ginseng to 79.4%, 71.7%, and 72.5% in the final products, respectively. HPLC analysis demonstrated that ginsenosides in cultured wild ginseng roots were distributed in a different ratio compared with red ginseng and white ginseng.

전남지역 인삼재배지의 토착 Arbuscular 균근균(AMF)의 분포와 감염특성을 파악하기 위해 곡성, 영광, 영암, 해남 지역을 대상으로 58개 지점의 토양과 인삼 시료를 채취하여 조사하고 AMF 밀도와 토양특성을 조사하였다. 조사지역의 전체 평균 포자밀도는 건토 1 g당 3.4~5.9개의 분포를 보였으며, 재배연수 3년근 재배지까지는 포자밀도가 다소 증가하는 경향을 보였고, 자연상태 토양 중의 AMF 포자밀도는 건토 1 g 당 6.3~14.7개로서 인삼재배지 보다 포자밀도가 높았다. 포자크기별 분포는 직경 $45{\sim}106{\mu}m$ 범위에 74.3% 정도가 포함되었으며, AMF의 감염 양상은 Paris-type이 주를 이루었다. 평균 감염율은 영암지역의 재배지에서 64.4%로 높게 나타났으나 그 밖의 지역은 40~50%범위를 보였다. 조사지역의 근권토양 중 AMF 외생균사의 길이는 건토 1 g당 0.5~4.4 m 범위로서 인삼의 재배연수가 증가함에 따라 외생균사(external hyphae)의 양이 많아지는 것으로 파악되었다.

The headspace volatiles of the Korean ginseng and the Chinese ginseng were extracted using the SepPak Cl8 cartridge (Wasters Co.) and were analyzed using GC/MSD. The overall GC pattern of the headspace volatiles of the Chinese ginseng was similar to that of the Korean ginseng, but the composition ratios of the two major components, $\beta$-panasinsene to $\beta$-muurolene, were quite different between them. The composition ratios of $\beta$-panasinsene to $\beta$-muurolene of the Korean red and white ginseng were 1.02$\pm$0.28 (n=19) and 1.49$\pm$0.55 (n=14) , respectively. However the com- position ratios of the Chinese red and dried ginseng were 0.58$\pm$0.19 (n=41) and 0.57$\pm$0.17 (n=28), repetitively, which were significantly lower than those of the Korean ginseng at I% level. The composition ratio of the two major headspace volatile components, $\beta$-panasinsene to ${\gamma}$-muurolene, is thought to be as a useful indicator for differentiating the Chinese ginseng with the Korean ginseng.

The ether extract of the dried powdered roots of Korean ginseng was fractionated by column chromatography. Limonene, terpineol, eucalyptol, ${\alpha}$-phellanderene and citral were identified in the essential oil fraction of the ether extract by TLC and GLC.

The effect of granule size of dried red ginseng extract on physical characteristics on tablet such as hardness, color, yield and disintegration time was studied. A moisture proofing agent was found to be necessary to form granules without serious absorption of moisture. The result showed that decrease in particle size resulted increase of values in weight, hardness and disintegration time. The granule size of 60∼80 mesh was found to be optimum for proper color uniformity and other physical characteristics of tables.

The pith and xylem parts of fresh root that turned into inside-white during processing for red ginseng was investigated under scanning electron microscope in comparison with the sa31e position of fresh root processed into normal reddening. In the inside-white part starch storage cells remain mostly in vacancy or with small number of starch granules and with large hollow by missing cell membranes between cells. Many starch seed granules appeared on the surface of storage cell wall in the inside-white part. Fresh root sample showed better picture than dried powder.
