This study was conducted to investigate the optimum temperature and light intensity of photosynthesis and transmittance in the shade for better growth and root yield of ginseng. The 3-year-old ginseng plants grown under the shade of 5, 10 and 20% transmittance did not show any significant difference in the stem length, stem diameter, leaf area and root length. The root diameter markedly increased under the shade of 10% and 20% transmittance, and the root was the heaviest under the shade of 20% transmittance. The 6-year-old ginseng plants grown at 20% transmittance showed the largest root diameter but the root length was not influenced by transmittance. The root was heaviest in the shade of 20% transmittance.

In order to study the effect of honey concentration on the quality of honeyed ginseng in the process of manufacturing honeyed ginseng, honeyed ginseng was manufactured under the various condition of honey concentration, 40 brix, 50 brix, 60 brix and 70 brix and the approximate composition, the yield and organoleptic test of them were investigated. The results obtained were as follows. 1. The higher honey concentration was used, the yield of honeyed ginseng was increased. 2. The higher honey concentration was used, the amount of total sugar was increased while the amount of crude saponin, crude protein. crude fat, crude fiber and crude ash was decreased. 3. Free sugars of honeyed ginseng consist of rhamnose, xylose, fructose, glucose, sucrose and maltose, 4. The amount of saponin lost in the process of manufacturing honeyed ginseng was 2.5%-5.0%, therefore honey concentration was not so effective on the loss of saponin. 5. According to organoleptic test, H-3 and H-2 treating honey concentration at 60 brix and 50 brix was the best and better of all.

Background: In this study, the fermentation of ginseng seeds was hypothesized to produce useful physiologically-active substances, similar to that observed for fermented ginseng root. Ginseng seed was fermented using Bacillus, Pediococcus, and Lactobacillus strains to extract ginseng seed oil, and the extraction yield, color, and quantity of phenolic compounds, fatty acids, and phytosterol were then analyzed. Methods: The ginseng seed was fermented inoculating 1% of each strain on sterilized ginseng seeds and incubating the seeds at $30^{\circ}C$ for 24 h. Oil was extracted from the fermented ginseng seeds using compression extraction, solvent extraction, and supercritical fluid extraction. Results and Conclusion: The color of the fermented ginseng seed oil did not differ greatly according to the fermentation or extraction method. The highest phenolic compound content recovered with the use of supercritical fluid extraction combined with fermentation using the Bacillus subtilis Korea Food Research Institute (KFRI) 1127 strain. The fatty acid composition did not differ greatly according to fermentation strain and extraction method. The phytosterol content of ginseng seed oil fermented with Bacillus subtilis KFRI 1127 and extracted using the supercritical fluid method was highest at 983.58 mg/100 g. Therefore, our results suggested that the ginseng seed oil fermented with Bacillus subtilis KFRI 1127 and extracted using the supercritical fluid method can yield a higher content of bioactive ingredients, such as phenolics, and phytosterols, without impacting the color or fatty acid composition of the product.

This study was carried out to investigate the difference of growth characteristics, yield and extract content between upland and paddy ginseng cultured with 4­year-old ginseng in 2003. Although upland ginseng showed larger variation in yield than that of paddy ginseng, the average of it was greater than that of paddy ginseng because it showed better growth of aerial part and higher survival rate than that of paddy ginseng. Moisture content of fresh root was $71.8\%\;(68.5\~73.1\%),\;and\;72.7\%\;(70.2 \~74.9\%)$ on average in upland and paddy ginseng, respectively. Paddy ginseng showed higher hardness in taproot, and higher rate of rusty colored root than that of upland ginseng. The ratio of taproot dry weight in upland ginseng was smaller than that of paddy ginseng, while that of lateral root was larger in upland ginseng. Ratio of marketable root (>60g) to total harvested roots was $13.7\%\;(0.82\~8.0\%)\;and\;7.7\%\;(1.6\~12.6\%)$ in upland and paddy ginseng, respectively. Extract content did not show distinct difference between upland and paddy ginseng, but it showed large variation from $16.1\;to\;25.1\%$ in taproot, and from $24.2\;to\;32.5\%$ in lateral root depanding on the ginseng field examined.

Growth characteristics, root yield and ginsenoside contents of 3-year-old ginseng in greenhouse shaded by $30^{\circ}$ sloped-curtain made of aluminum were compared to traditional shade facility in order to develop cultural practice for organic ginseng. Light transmittance ratio in greenhouse with $30^{\circ}$ sloped-curtain shade was distinctly lower than that of traditional shade from sunrise to 9 a.m., while its ratio in greenhouse was higher than traditional shade since 9 a.m. due to the reflection of light. Air temperature of greenhouse was $1.3^{\circ}C$ higher than that of traditional shade on the first ten days of August due to more reflected light. Root yield of greenhouse was 44% higher than that of traditional cultivation because of the inflow of reflected light and the decrease of disease of Alternaria and Anthracnose by blocking rainfall. Dry matter partitioning ratio of rhizome and lateral root were increased in ginseng cultivated at greenhouse due to longer survival time in leaf than traditional cultivation. Total ginsenoside contents cultivated at greenhouse was decreased in the part of taproot, while it was increased in the part of lateral and fine root compare to traditional cultivation. Individual ginsenoside contents between greenhouse and traditional cultivation showed significant difference more frequent in fine root than taproot and lateral root. Total ginsenoside contents including $Rb_1$, $Rb_2$, Rc, Rd, Re, Rf, $Rg_1$, and $Rg_2$ in whole root of 3-year-old ginseng did not showed significant difference by greenhouse and traditional cultivation.

Ginsenosides are active constituents of ginseng (Panax ginseng) that have possible anti-aging, physiological and pharmacological activities, such as anti-cancer and anti-inflammatory effects. Although the ginseng root is generally used more often than the aerial parts for medicinal purposes, the flowers also contain numerous ginsenosides, including Rb2, Rc, Rd, Re and Rg1. Therefore, an extract from the flowers of the P. ginseng could have the pharmacological efficacy of bioactive compounds including ginsenosides. The high hydrostatic pressure extraction (HHPE) is a method that is used for the efficient extraction of bioactive compounds from plant materials. In this study, we compared the yield of ginsenosides from ginseng flowers under different conditions of extraction pressure and time of HHPE. The results indicate that the total yield of the ginsenosides improved as the pressure increased from 0.1 to 80 MPa and treatment duration increased to 24 hours. In addition, the ginsenoside extracts from HHPE at 80 MPa, which possessed a higher total ginsenoside concentration, decreased the viability of the primary human epidermal keratinocytes (HEKs) significantly than the ginsenoside extracts from HHPE at 0.1 MPa. Collectively, we found that the method of HHPE that was performed for 24 hours at 80 MPa showed the highest yield of ginsenosides from the flowers of P. ginseng. In addition, our study provides a foundation for the efficient extraction of ginsenosides, which had a potent bioactivity, from flowers of P. ginseng through HHPE.

The swelling and hydration properties of Korean red ginseng tails and yield of total solids in extract were studied during extraction with ethanol solution having a concentration of 0-90% at $60-100^{\circ}C$. Extraction was carried out 5 times which was taken 8 hours per each time of extraction. The swelling, hydration and total solids yield were increased as the ethanol concentration decreased and as the extraction temperature raised. The cumulative value of solids yield suggested that three times of extractions with water or 70% ethanol were effective to recover more than 84%. Linear regression analysis on the properties investigated and extraction conditions showed a linear logarithmic relationship .

In ginseng fields, soil organic matter content showed significant positive correlation with soil moisture content and root yield. Soil moisture content showed significant positive correlation with root yield, stem diameter and stem length but significant negative correlation with relative missing plant rate, defoliation and alternalia bright infection. For more than 2 Kg yield per Kan under present cultivation technique, soil moisture appeared to be greater than 17% and organic matter 2%. Many fields (58%) were below this requirement and belong to sand loam and loam soils.

Root yield and quality of ginseng cultured in paddy soil was low relatively compared with that of upland soil because of moisture injury in root during rainy season. Drainage class in soils generally divided into 6 classes, and it is possible to cultivate ginseng practically in imperfectly drainage class (IDC). This study carried out to select the varieties that is suitable for paddy soil, which is easy to be generated rusty-colored root and physiological-discolored leaf. Experiment plot arranged with the condition of soil humidity contents such as poorly drainage class (PDC) and imperfectly drainage class (IDC), and upland soil. Growth characteristics and root yield were investigated in four-year-old ginseng of varieties, Cheonpoong (CP), Yeonpoong (YP), Hwangsookjong (HS), and Jakyeongjong (JK). CP among four varieties showed the highest yield in IDC and CP was the lowest ratio in leaf discoloration and rusty-colored root. HS was followed by CP in the order of root yield, but it had the weakness that the ratio of rusty-colored root was high respectively.
