Mineral that is included to wild ginseng rhizomes that is assumed that is born at X-ray diffraction(XRD) analysis result 20 appears as is different according to each part by whewellite. Whewellite is accumulated much on rhizomes in wild ginseng, but do not exist hardly from mail body of root. The 6 years that in rhizomes of ginseng yet whewellite decision unobserved. This is considered by thing associated with ingredient of growth period of mineral and soil of plantation. For from, may present possibility of years distinction if analyze ginseng, wild ginseng etc. variously. Whewellite's chemical formula seems to be decision that combine with carbon(C) of air by photosynthesis function that Ca because is CaC$_2$O$_4$(H$_2$O) in rises by rhizomes through radices and is formed.

This study was carried out to get basic information that can be used in quality control for processing ginseng products and also in separation of pure ginsenosides for experimental purpose. The composition of various parts of 6 year-old ginseng was 4.1% of rhizome (node), 47.7% of main root, 34.1% of lateral root and 14.1% of fine Toot on dried weight basis. The weight ratios of epidermis-cortex and xylem were about 1 : 1 in main root and about 2 : 1 in lateral root. The distribution of total saponin content shows 29.2% in main root, 34.6% in lateral root, 29.1% in fine root and 7% in rhizome, but the order of the content per unit weight was fine root > rhizome > lateral root > main root. Total saponin content according to age of root was increased gradually within 3% for 6 years, as compared with two year old root. In view of the increase of root weight owing to the net amount of saponin in root increased continuously. The increase rates of total saponins per year were 3.1,12.3,19.8,43.8 and 21.1% in 2, 3, 4, 5 and 6 years-old ginseng root, respectively.

The present study was performed to evaluate the cytotoxicity of white and red ginseng extracts against cancer cells in vitro. We also examined the effects of those ginseng extracts on the cell cycle by using flow cytometry. We divided each white and red ginseng into two parts, main body and rhizome, and tested the cytotoxicity of each fraction against various mouse-originated cancer cells and mouse peritoneal macrophages. The red ginseng was more cytotoxic to the cancer cells in comparison with white ginseng, and the rhizome fractions were more cytotoxic than the mainbody fractions in the both of white and red ginseng. Among the cells tested, RAW264.7 cancer cells were most sensitive to all the ginseng fractions. In cell cycle analysis, all the fractions of white and red ginseng arrested the cell cycle at G$_2$/M phase.

인삼(수삼)은 장기 유통할 때 품질관리에 어려움을 겪고 있고 이는 잘못된 저장, 세척 등의 기술에서 비롯되는 것으로 포장 기술만으로는 고품질 수삼 유통을 실현하기 어렵다. 따라서 연구결과를 토대로 수출용 인삼 수확후 품질관리 과정을 정리하여 매뉴얼화 하였다. 인삼의 수확후 생리적 특성과 품질저하 요인은 물론 수확에서 저장, 세척·건조, 상품성 향상 포장 방법, 냉장컨테이너 적재, 저온 수송 및 판매 시 주의사항 등을 기술하였다. 수삼의 유통 중 손실율에 가장 크게 영향을 미치는 요인은 물러짐과 곰팡이 발생에 의한 부패, 뇌두부위 출아에 의한 상품가치 하락으로 나타났다. 출아는 수확 시기에 따라 다르게 나타나 가을수확 수삼에서는 저장기간 뇌두부위 출아는 전혀 발생하지 않았고, 봄수확 수삼의 경우 수확시기가 늦으면 뇌두 출아가 증가하는 경향을 보였다. 부패 병원균은 25℃ 운송 시 Fusarium spp.가 15, 5, 1℃ 운송 시 Botrytis spp.가 주를 이루었다. 포장단위를 5kg 대포장과 500g 소포장으로 하였을 때 소포장의 물러짐 현상이 대포장보다 훨씬 높게 나타나는 반면 곰팡이 발생에 의한 부패는 대포장보다 낮게 나타났다. 수삼 저장온도에 따라 유통 중 품질이 크게 달라져 온도 -2℃ 이하에 저장한 수삼은 유통 중 손실률이 높고 특품의 비율이 낮아지는 등 품질이 저하되며 저장기간이 길수록 더욱 심화되는 반면 0℃ 저장 수삼은 저장 3개월 후에도 유통 중 품질의 변화가 적었다. 이러한 결과를 종합적으로 정리하여 인삼의 전통적인 수확후 관리 방법이 아니라 수출용 인삼의 품질 향상을 위해 개선된 수확후 관리 방법을 적용할 수 있도록 흐름도로 정리하였다.

The contents of some chemical constituents in several parts of Panax ginseng were investigated. Each part of ginseng was extracted with 70% ethanol and then water. The yield of extract was the highest in fine root, and relatively low in roughly dried ginseng and white ginseng, On the other hand, the contents of total sugars in white ginseng and seedling ginseng were high, but low in leaf and peel. The contents of crude protein in roughly dried ginseng and white ginseng were high, but those in leaf, rhizome (nod) and peel were low. The content of crude fat was higher in leaf than in other parts of ginseng plants and that was the lowest in fine root. Among free sugars, the content of fructose was high in leaf and rhizome, but that was the lowest in fine root. In the case of glucose content, leaf contained the highest amount, but fine root did the lowest. Sucrose contents in white, roughly dried and lateral roots were high, whereas that in leaf was low.

This study was carried out to evaluate the basic information on ginsenoside contents and pattern similarity in five cultivars of Panax ginseng C.A. Meyer. Among five cultivars the unit content and total content of ginsenosides were the highest in Gopoong cultivar as 18.9 mg/g and 596 mg/root, respectively. The unit content and total content of ginsenosides decreased in the order of Yunpoong, Gumpoong, Seonpoong and Chunpoong cultivar. Ginsenoside pattern similarity between tap root and lateral root was high as 0.95 but that between tap root and fine root was low as 0.72. Correlation of ginsenoside contents between tap root and lateral root exhibited the highest value as 0.843 and decreased in the order of main root, fine root, and rhizome. And the correlation value between unit content and total content of ginsenoside was very high as 0.933.

Comparative analysis of paeoniflorin, albiflorin and phenolic compound contents as bioactive components of peony was performed by Reverse Phase-High Performance Liquid Chromatography (RPHPLC) using the four- year-old peony which were different plant parts and pretreatment, such as removing or unremoving the cork layer of peony root before drying. The contents of paeoniflorin, albiflorin, (+)-taxifolin $3-O-{\beta}-D-glucopyranoside$, (+)-catechin and (-)-epicatechin were the highest in rhizome part, but those of gallic acid and benzoic acid in the leaves were higher than other parts. The contents of albiflorin, gallic acid, benzoic acid and (-)-epicatechin in the cork layer were higher than in those of the core, but the contents of paeoniflorin, (+)-taxifolin $3-O-{\beta}-D-glucopyranoside$ and (+)-catechin in the core were higher than those in the cork layer. In general, the rhizome part of peony root has been used only propagation purpose, but this part contained high contents of bioactive component. Therefore, it is needed that medicinal application of rhizome part in peony root was firmly investigated. Also, In the use of peony root for medicinal purpose, the use of peony root with cork layer can be efficient way on the practical use of useful components and the reduction of labor for removing the cork layer.

This experiment was conducted to find identification of ginseng root's age using the number of stem vestiges in rhizome. The number of stem vestiges in rhizome is a useful key to confirm the age of ginseng root as follow : 4-year-old root has two, 5-year-old root has three, 6-year-old root has four. The distribution of stem vestiges in rhizome each year root are as follow : 2 stem vestiges in 4-year-old root is 89.5%, 3 stem vestiges in 5-year-old root is 79.7%, 4 stem vestiges in 6-year-old root is 46.3%. However, the limiting factors of identification of ginseng root's age using the number of stem vestiges in rhizome is appearance of multi-stem per plant and appearance of destroyed stem vestige in rhizome. The ratio of appearance of multi-stem per plant and destroyed stem vestige in rhizome are increased according to root age.

Crystalline calcium oxalate occur throughout near)y all plants species in five major forms; styloids, druses, raphids, prisms and sands. These crystals are known to be distributed in specific tissue such as cortex, xylem, phloem, cambium and epidermis. This research was undertaken to identify the occurrence, type, location and ultrastructure of druse crystals in Panax ginseng. In situ visualization, conventional light microscopy, histochemistry and scanning electron microscopy were applied for these purposes. Druse crystals in ginseng were identified as calcium oxalate by silver nitraterubeanic acid histochemistry. Calcium oxalate crystals are observed in nearly all plant organs such as leaf, petiole, peduncle, stem, rhizome, tap root and lateral root except fine root. Most frequent observation of crystals in the leaf and rhizomes were noticed. Three different types of calcium of oxalate druse crystals were identified by scanning electron microscopy.
