This study was undertaken to evaluate the automatic decision-making on the grading of 6-year-old fresh ginseng (Panax ginseng C.A. Meyer) by an image analyzer. The best input method for the 6-year-old fresh ginseng was under condition of a low resolution (128u 128 pixel) and illumination direction from bottom to up (light box). It was possible to identify the main root, lateral root, and rhizome of fresh ginseng by application of OPEN process in a function of an image analyzer. Finally, we developed the grade decision-making programs, GinP-1. The fitness rates for the fresh ginseng standards which were classified by experts were 94.6, 80.6, 81.5, and 100.0% for 1st, 2nd, 3rd, and 4th grade of fresh ginseng, respectively, and the total time of decision-making was about 4.3 seconds per one root. The decision-making time was reduced to 0.8 seconds per one root by enhancemeat of the Image analyzer, which was tested by the technical company of the image analyzer,'Carl Zeiss (Germany). As a result of this study, the automatic decision-making on the grade of fresh gin send by image analyzer seems to have high possibility.

This study aims to analyze the differences of ginseng product consumers and segment Korean fresh ginseng and red ginseng root markets based on attributes for the purchase. As a result of analyzing survey data, the red ginseng root consumers had different aspects from fresh ginseng consumers. According to the result of cluster analysis, the fresh ginseng consumers were subdivided into three segments (safety-oriented consumption cluster, label centered consumption cluster, and high involvement consumption cluster), while the red ginseng root consumers were subdivided into four segments (convenience-oriented consumption cluster, high involvement consumption cluster, raw material's safety-oriented cluster, and raw material's information importance cluster). ANOVA and Crosstab were conducted to investigate characteristics of each cluster.

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.

식물조직배양기술을 이용하여 인삼 root를 생산하고자, 식물생장조절물질로 유도된 인삼 root를 사용하여 최적액체배양조건을 RSM을 이용하여 조사하였다. 최적액체배양조건을 배지의 pH, sucrose 농도, nitrogen 농도, phosphate 농도의 3 level-4factor의 fractional factorial design에 의하여 조사한 결과, 인삼 root의 생장율은 최저 1.00g에서 최고 2.33g까지 나타났다. 다중회기분석으로 구한 model식을 가지고 등고분석과 3차원분석을 수행한 후 독립변수의 최저 또는 최고수준에서 조속변수가 최대치를 나타내지 않는 배지의 pH와 sucrose농도의 변수에 대하여 model식을 편미분한 결과 인삼 root의 최적액체배양조건은 pH5.6, sucrose 3.8%, nitrogen 50mg/L, phosphate 80.7mg/L로 예측되었다. 이렇게 결정된최적조건값들을 model식에 대입하여 얻은 예상치는 2.36g 이었다.

Polyamine constituents of fresh Panax ginseng root and dried white ginseng were extracted with 5% trichloroacetic acid, respectively. The isolation of polyamine constituents was conducted by the cation exchange chromatography using $Dowex-50W{\times}8$ resin and the detection was performed with TLC. Identification of the polyamine was carried out by the methods of IR, NMR, MS spectroscopy and GLC. Polyamine constituents of white and fresh ginseng root were identical and composed of five different polyamines. The major polyamine in white and fresh ginseng root was determined as putrescine.

This study was carried out to investigate change of ginsenoside contents in red and fresh ginseng according to root part and age by hydrolysis. Neutral total ginsenoside contents by hydrolysis in 6-year main root and lateral root were significantly increased than those by non-hydrolysis, as 41.6 and 32.8%, respectively. However, there was no significant difference in red ginseng. In fresh ginseng, ginsenoside contents of the protopanaxatriol group such as Re, Rf, $Rg_1$, $Rg_2$, and $Rh_1$ were not significantly different, but $Rb_1$, $Rb_2$, $Rb_3$, Rc, and Rd showed significant difference. The increase rate of neutral total ginsenoside content by hydrolysis was higher in epidermis-cortex than stele. Also, the neutral total ginsenoside content was fine root > rhizome > lateral root > main root, respectively. While there was no tendency towards the increase of ginsenoside by hydrolysis with the increase of root age in fine root and rhizome, there was significant decrease in main root and lateral root.

The investigation of UV absorbing compounds in saponin fraction of Pnm.1. Kiairnk root was carried out by thin layer chromatography, semipreparative HVLC. l3C, 1H-NMR, mass spectrometry and chemical characteristics in searching plant for growth regulatony substances such as phenolic glycoside. Drying of fresh ginseng at 15 $^{\circ}C$ decreased not only number but also size of UV absorbing sports on TLC. One of the relatively large spots in fresh ginseng was isolated and identified as adenosine, which is subjected for growth stimulatory activity Detection of phenolic glycosides failed in dried root bolt was highly probable in fresh ginseng even with the insufficient amount of sample.

본 연구는 현재 수삼수납 시 품질검사요원의 관능검사로 판정되고 있는 6년근수삼의 적변판정에 대하여 영상분석기를 이용한 수삼의 적변 자동판정 시스템을 개발하고자 수행하였다. 영상분석기에 의한 수삼 총면적에 대한 grey valuequf 면적비율을 조사하여 이에 대한 회귀 및 판별분석을 실시한 결과, 정상삼과 적변삼을 구별할 수 있는 임계값은 총 면적에 대한 grey value 148에서의 면적비율(G148)로 분석되었으며, 임계값인 G(148)을 이용하여 다음과 같은 판별식을 구하였다. 적변삼의 판별식 : 6.67951$\times$G(148)+3.74122, 정상삼의 판별식 : 2.85942$\times$G(148)+9.95612, 본 판별식의 적중율은 89.8%로 이는 앞으로 계속적인 연구로 적변삼의 판정 적중율을 증가시킬 수 있을 것인 바, 컴퓨터 등 기계에 의한 적변 자동판정의 가능성은 매우 클 것으로 사료된다.

한국산 6개 지역(금산, 강화, 풍기, 음성, 진안, 홍천) 수삼의 ginsenoside 함량을 비교 분석하여 평균 및 분산분석(일원배치법)을 통계 처리한 결과, 함량의 평균치가 4년근 수삼이 가장 높은 함유량을 나타내었고, 다음으로 5년근, 6년근 순 이었으나, 인삼사포닌에 대한 연근별 차이에 있어서 통계적 처리에 의한 유의적 차이는 없었다. 동북아시아의 또 다른 인삼 재배지인 중국 길림성과 일본의 나가노산 수삼과의 ginsenoside 함량에 있어서는 한국 금산산 수삼이 중국 길림성산 및 일본산에 비하여 높은 함유량을 나타내었다.

Among many kinds of constituents of ginseng root, starch was the most noticeable component related to inside white in fresh ginseng. The ash of inside white section was higher in content and greenish gray in color. The water binding capacity and ash content of the starch from inside white fresh ginseng were higher than those of starch from normal fresh ginseng, but amylase content was not significantly different. Ash of inside white fresh ginseng starch contained higher in Ca, Mn and Fe content. Complexes of small granular starch and amino acids were rich in swelling power, and solubility by temperature change were similar between inside white fresh ginseng starch and normal one, but the former was more easily swelled than the latter.
