This research is to figure out the manufacture proper1ies and the effect of adding red ginseng powder into cookies. When adding red ginseng powder into wheat, there was no significant change in moisture content while the amount of WRC and AWFC increased significantly. In the manufacturing and quality characteristics, there was no noticeable change in thickness and spreadability. Also, wheat cookies containing red ginseng powder didn't show significant differences either and the control plot had the biggest diameter. The change of chromaticity showed that L-value and b-value seemed to significantly decrease while a-value increased a lot In other words, the more ginseng powder was added, the darker its external colour became. In the organic characteristics, the control plot showed the best result in volume, crust, top grain and in almost every part. The volume had the most satisfying result with 6% of red ginseng powder added, and there was not much difference among the groups added with red ginseng powder. Generally, adding up tp 12% of ginseng powder was found best when making cookies.

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.

1. Ginseng field and virgin soils, to which Yakto, washed Yakto, litters (deciduous and coniferous trees) and bone meal were applied, were incubated at 60% of field capacity of the soils to shed light on the production of $NH_4-N$ and $NO_3-N$ through mineralization of the organic materials being the nitrogen sources for Korean ginseng. 2. Total nitrogen content mineralized in the soils, to which the following organic materials were applied, was:bone meal>Yakto${\gg}$litter (deciduous trees)> washed Yakto, litter (coniferous trees). The content increased with incubation time in all the virgin and ginseng field soils excepting only the virgin soils applied with washed Yakto and litters of which the contents decreased. A large part of nitrogen mineralized in the virgin and ginseng field soils to which Yakto was applied was nitrate form, while a half ginseng field soils and a considerable part in the other virgin soils was ammonium form in the other treatments. 3. $NH_4-N$ content produced in the virgin and ginseng field soils applied with bone meal increased with the time, while it decreased in the other treatments. And the content in the soils applied with bone meal was very high. 4. $NO_3-N$ content showed a continuous increase during the incubation time in all treatments of ginseng field soils and only in the virgin soil to which Yakto was applied, wherease it showed almost no change in the other treatments of virgin soils. And the content in the soils applied with Yakto was very high. 5. Yakto was expected to supply nitrate enough to meet amounts of nitrogen required by ginseng with different ages and also expected to increase in soil fertility, while bone meal was expected only to supply much nitrogen of which a considerable part was ammonium form.

To find the relationship between the adequate amount of soil chemical components and ginseng growth including root weight, 49 farmer's red ginseng field from the main ginseng growing area were studied intensively. 1. The ranges of soil chemical component of high yield ginseng field were 8.9 to 14.5 me/100g of CEC 1.5 to 3.5% of organic matter, 45 to 257 ppm of available phosphorus, 0.34 to 0.55 me/100g of potassium and 0.002 to 0.012 of K/P ratio respectively. 2. Higher content of organic matter, CEC, exchangeable potassium and higher rate of K/P were observed in soils of ginseng field with high yield than in soils of low one. The CEC content in soil was positively correlated with the plant growth, and available phosphate content in soil was negatively correlated with yield of ginseng root. 3. There was highly positive significant correlation between root yield of ginseng and K/P ratio of ginseng soil. Similar result also observed between root yield of ginseng and K/P ratio of upper part of ginseng plant.

The aim of the double blind test was to assess the prophylactic and therapeutic efficacy of the preparation GINSANA, containing the standardized ginseng extract PHARMATON G115,. The determination was carried out with special emphasis on the following features : general physical condition, physical performance, mental performance, enjoyment of life/mood, concentration and memory, as well as sleeping habits. Sixty test persons took part in the study, men and women between the ages of 22 and 80. The 90-day test was carried out in the form of a double blind experiment. Experimental measurements were made and the persons were also questioned. The reaction time, the optical merging threshold, the coordination of both hands and the recovery quotients, as well as the recovery rates were analyzed. The results for the serum group were clearly better than those for the placebo group, particularly for the characteristics: general physical condition, physical performance and sleeping habits. The results of the test methods used, especially with regard to the reaction time, the coordination of both hands, the recovery quotient and the recovery period, permit the following conclusion to be drawn: when administered for several weeks, GINSANA has a positive action, in the sense of an activation of the entire personality by the ginseng glycosides contained in the standardized Extracts G115.

Twin-bud seedlings and four-leaflet seedlings of ginseng were found and transplanted to field and their growth characteristics were investigated. 1. Appearance frequencies of twin-bud and four-leaflet seedlings were 0.3 and 0.4 percent, respectively, in common nursery bed: and were 6.6 and 28.4 percent, respectively, in polystem line. 2. Generally, the growth of twin.bud and four-leaflet seedlings were better than those of common seedlings both in aerial part and in root. Root weights of both type seedlings exceeded the common ones by 66 and 38 percent, respectively. 3. When they became two-year-old plants, leafiet number of common plant was 11.6, and those of twin-bud and four-leaflet-seedling plants were 18.1 and 13.8, respectively. There were no inflorescence in twin-bud-seedling plant, but the ratios of in florescent Plant in four-leaflet.seedling and common plant were 44.0 and 12.5 percent, respectively. 4. In two-year-old plant, root weights of twin-bud and four-leaflet-seedling plants were heavier than those of common ones by 27 and 20 percent, respectively.

Ginseng plants in the 2nd year were grown under the shade (90-95%) of colored cellophane films at $15^{\circ}C$ in a natural light phytotron. Relative root grown (final/initial) was in decreasing order of blue, green, white, yellow and red. The growth of aerial part, especially stem length was poorest in blue light with relative root growth negatively correlated with stem length. In this relation each color showed specific domain. Stem length showed positive linear correlation with leaf area per plant in each and among light though it was not significant in red light. The content and ratio of chlorophyll a and b in leaf were in the decreasing order of White, Blue, Green, Red and Yellow. There is positive correlation between chlorophyll a and chlorophyll b, and between total chlorophyll and chl:a/b ratio. Blue color shade is expected to be beneficial for ginseng production.

Catecholamines are among the first molecules that displayed a kind of response to prolonged or repeated stress. It is well established that long-term stress leads to the induction of catecholamine biosynthetic enzymes such as tyrosine hydroxylase (TH) and dopamine ${\beta}$-hydroxylase (DBH) in adrenal medulla. The aim of the present study was to evaluate the effects of ginseng on TH and DBH mRNA expression. Repeated (2 h daily, 14 days) immobilization stress resulted in a significant increase of TH and DBH mRNA levels in rat adrenal medulla. However, ginseng treatment reversed the stress-induced increase of TH and DBH mRNA expression in the immobilization-stressed rats. Nicotine as a ligand of the nicotinic acetylcholine receptor (nAChR) in adrenal medulla stimulates catecholamine secretion and activates TH and DBH gene expression. Nicotine treatment increased mRNA levels of TH and DBH by 3.3- and 3.1-fold in PC12 cells. The ginseng total saponin exhibited a significant reversal in the nicotine-induced increase of TH and DBH mRNA expression, decreasing the mRNA levels of TH and DBH by 57.2% and 48.9%, respectively in PC12 cells. In conclusion, immobilization stress induced catecholamine biosynthetic enzymes gene expression, while ginseng appeared to restore homeostasis via suppression of TH and DBH gene expression. In part, the regulatory activity in the TH and DBH gene expression of ginseng may account for the anti-stress action produced by ginseng.

A large number of individual ginseng plants have been selected in the farmer's fields to develop new ginseng varieties with desirable traits since 1970s. Among them, Hwangsukjong with green stem and yellow berry was selected as a ginseng germplasm. The phenotype of Hwangsukjong is quite different from Jakyungjong that has violet stem and red berry and has been cultivated in most of ginseng fields. Therefore, Hwangsukjong was crossed with Jakyungjong to clarify the inheritance of stem color and then the characteristics of $F_1\;and\;F_2$ hybrids were investigated. $F_1$ hybrid plants were similar to Jakyungjong in most of aerial part characters and showed hybrid vigor in fresh weight of root and weight of 100 seeds. In $F_2$ generation, the stem color was segregated in a ratio of 3 violet to 1 green. From this result, it was elucidated that violet color was controlled by single dominant gene. In another experiment, DNA was extracted from parents (Jakyungjong and Hwangsukjong) and $F_1$ hybrid. For each primer evaluated, multiple band profile was produced comprising from one to five major bands plus a varying number of minor bands and amplified bands were detected among most primers. In case of UBC primer number 13, 17, 30, 31, and 43, band patterns of parents and $F_1$ hybrid were very similar, but the others were not. Especially, in {\sharp}1$, {\sharp}4$, and {\sharp}33$, specific band was produced in Hwangsukjong and $F_1$ hybrid while in {\sharp}6$, another specific band was produced in Jakyungjong and $F_1$ hybrid. Therefore, $F_1$ hybrid had all specific bands at these primers. So, these selective markers could be used for identification of characteristics of $F_2$ hybrids

The present study was carried out to identify the distribution characteristics of heavy metals in ginseng and wood-cultivated ginseng reduction of dietary exposure. Samples of ginseng and wood-cultivated ginseng were collected from 14 and 5 regions across Korea, respectively. Lead (Pb), cadmium (Cd) and arsenic (Ar) were detected by ICP-MS after microwave digestion, whereas aluminum (Al) was determined using ICP. Cultivated ginseng peels were 16.2% of whole root, while the peels and fine roots amounted to 21.8% and 16.8% of whole wood-cultivated ginseng, respectively. Taking into account the weight and concentration of the heavy metals by root part, their distribution ratios were calculated and compared. The cultivated ginseng peels contained 40.3% Pb, 25.9% Cd, 47.6% As, and 89.9% Al. Meanwhile, heavy metals consisting of 27.2% Pb, 28.2% Cd, 48.3% As, and 56.8% Al were distributed in the peels of the wood-cultivated ginseng. There was no significant difference between the peels and fine roots of the wood-cultivated ginseng with respect to the distribution proportion of heavy metals, except for Al. These results indicate that the level of dietary exposure to heavy metals could be reduced by peeling ginseng and wood-cultivated ginseng prior to consumption.
