Microwave-assisted process (2,450MHz), which is known as a more environmental-friendly process with economic advantages than the current extraction methods, was investigated to pre-establish the extraction conditions for soluble ginseng components used for the processing of ginseng products. The extractions of soluble ginseng components showed optimum conditions, such as 60 mesh in particle size, 1 : 10 (g/mL) in the sample to solvent ratio, and less than 100 watts in energy efficiency. Under these conditions using along with 60% ethanol for 5 min, the overall yield of ginseng extracts was about 83%. Most soluble components including saponins were extracted by repeating five times of microwave-assisted extraction.

Ginsengs(1-3 years old) from the Keumsan were analysed for the rare earth element(REE) contents and compared with their soils from the biotite granite(CR), phyllite(PH) and shale(SL) areas. In the soils, high REE contents and correlations were found in the SL. In the ginsengs, high element contents were shown in the SL. High correlations were found in the 3 year. In the upper parts, the 2 year of the GR was mainly high. Comparing with the same aged ginsengs, high elements were shown in the SL. Positive correlations were dominated and high correlations were shown in the 3 year ginsengs. In the root parts, the GR was high in the 2 year while the PH and SL were high in the 3 year. Comparing with the same ages, high elements were shown in the SL. High correlation relationships were found. Comparing between upper and root parts, the upper parts were mainly high, LREE showed big differences and relative ratios of the 2 year were mainly high. Comparing between soils and ginsengs, the soils were mainly high. Ratios between soils and root parts(soils/root parts) were higher than those of the upper parts. Ratios of the LREE showed big differences relative to those in the HREE and the ratios increased with ages. Overall results suggested that ginsengs of the SL were similar to those of soils and those of the PH showed big differences.

Direct seeding is a cultivation method of Korean ginseng which can cut down production cost and increase productivity. This study was conducted to obtain detailed information about this method and to aid the development of it in Korea. Major pre-crops before ginseng cultivation were rice, corn and rye, and organic matters, such as rice straw, rye straw and poultry feces were used for basal fertilization. In direct seeding of the ginseng field, seeding density was 196 to 210 seeds per $3.3m^2$ and germination ratio was 67%. Survival ratio of 4-year-old ginsengs which were products of direct seeding was 51%, and more than 100 plants per $3.3m^2$ survived. The most critical diseases in the directly seeded ginseng field were grey mold, damping off, and stem diseases including stem spot disease. Plant growth of the ginseng cultivated by the direct seeding method was not different from the ginseng cultivated by transplanting method. But the root of the ginseng cultivated by the direct seeding method took the shape of a shorter main root compared to the ginseng cultivated by the transplanting method. Root yield per $3.3m^2$ of the direct seeding ginseng field was larger compared to the field of the transplanting cultivation.

Baengnyeongdo Island, which belongs to Ongjin-gun, Incheon, is an island in the northernmost part of the West Sea in South Korea. Baengnyeong Island is the 15th largest island in Korea and covers an area of 51 km². The Korea Ginseng Corporation (KGC) investigated the possibility of growing ginseng on Baengnyeong Island in 1996. In 1997, thanks to the support of cultivation costs from Ongjin-gun, the first ginseng seedbed was built on Baengnyeong Island. In 1999, the seedlings were transplanted to a permanent field under a contract with KGC. In 2003, the first six-year-old ginseng harvest was performed, and KGC purchased all production according to the contract. Since then, KGC has signed on to grow ginseng until 2012 and purchased six-year-old ginseng until the fall of 2016. Since 2014, the GimpoPaju Ginseng Agricultural Cooperative Association has signed a ginseng production contract. According to a survey of nine 6-year-old ginseng fields (total 5,961 units) on Baengnyeong Island, the top five with good growth had a survival rate of 42.6 to 68%, and the bottom four with poor growth had an extremely low survival rate of 11.1 to 21.3%. The four fields with low survival rates were where hot peppers were planted before ginseng cultivation. It is believed that the excess nitrogen remaining in the soil due to the treatment of compost or manure during pepper cultivation causes ginseng roots to rot. The average incidence of Alternaria blight was 8.6%. Six six-year-old ginseng gardens were low at 1.1 to 4.7%, while the other three were high at 16.7 to 20.9%. It is assumed that the reason for the low survival rate and high incidence of Alternaria blight is a rain-leaking shield. Farmers used rain-leaking shields because the precipitation on Baengnyeong Island was smaller than on land. One field showed 3% of leaves with yellowish brown spots, a symptom of physiological disturbance of the leaf, which is presumed to be due to the excessive presence of iron in the soil. To increase the production of ginseng on Baengnyeong Island, it is necessary to develop a suitable ginseng cultivation method for the island, such as strengthening the field management based on the results of a scientific study of soil, using rain-resistant shading, and installing drip irrigation facilities. I hope that ginseng will become a new driving force for the development of Baengnyeong Island, allowing ginseng products and food to thrive in the beautiful natural environment of the island.

This paper is to assess the effect of Adaptagen as a radioprotector in which main component is alkaloid fraction of ginseng. Evaluation was made in vitro and in vivo study with NIGP(S) mouse by the measurement of regeneration of jejunal crypt cell and micronucleus assay to analyze radioprotective effect of ginseng alkaloid fraction in comparison with that of water fraction after whole body irradiation. The results were as follows, 1. The degree of radiation damage of mouse jejunal crypt cell was diminished in both of alkaloid and water fraction groups compared to control group but more in alkaloid fraction group than water fraction group. Regeneration of mouse jejunal crypt cell was higher both in alkaloid and water fraction groups than control group. 3. In vitro study, frequency of micronucleus was diminished in tendency for the treated groups than control group but statistically insignificant. 4. In vitro study, frequency of micronucleus was diminished in both alkaloid and water fraction groups compared to control group but more in alkaloid fraction group than water fraction group.

Ginseng was first addressed ever in the medical record in HyangYakGooGupBang (鄕藥救急方), the oldest Korean medical book published in Kingdom of Goryeo (918-1392) when Ganghwa was the provisional capital city at the time. It is believed that ginsengs in Ganghwa were planted and cultivated from 1100s. Intensive ginseng production in Ganghwa began when Ganghwa became the special district of the Kaesong Ginseng Union (開城人蔘組合) in 1920s, this intensive production continued till the Korean War in 1950. After the Korean War ended in 1953, ginseng production was resumed. In 1967, Ganghwa Ginseng Association (江華蔘業組合) was founded. The total acreage of ginseng harvested was nearly 200 ha in 1967 and it increased to ha 900 in 1974. By mid-1970s, Ganghwa became the largest ginseng region in Korea by total production and acreage. Most of ginseng roots cultivated in Ganghwa are six years old. Ganghwa, which was already well-known for red ginseng productions, has become even more famous for ginseng production.

Effect of crude saponin and raw ginseng juice on root rot pathogens such as Fusarium solani and Erwinia carotovora for there growth or spore germination was investigated. Macroconidial germination of F. solani was decreased as the incrasee of the crude saponin concentration. especially, percentage of the germination was remarkably reduced when the concentration was more than 500ppm. The spore production of F. solani was also reduced as the increase of the crude saponin concentration and this phenomenon was particularly profound on a solid medium. Mycelial growth was decreased when the crude saponin was added, while the effect of the concentration was not apparently significant. The higher concentration of raw ginseng juice is, the more the growth of F. solani. Growth of E. carotovora was enhanced by crude ginseng saponin and raw ginseng juice. The crude ginseng saponin stimulated the growth of E. carotovora as the increase of the concentration, while more growth of the bacteria obtained at $1\%$ raw ginseng juice added.
