Powders prepared from three different varieties Korean Ginsengs(white, red and black) are readily available ingredients and are consumed daily by many Korean as a functional food material. These variants of Ginsengs are known to exert a variety of physiological effects. Therefore, in this study, we assessed the physiochemical characteristics of Korean Ginseng Dasik prepared with different 3 types of Ginseng powder. We conducted a sensory evaluation analysis, and assessed the mechanical characteristics, Hunter's color values, and general compositions of 3 types of Korean Ginseng Dasik stored at room temperature(20$^{\circ}C$). The results of our sensory evaluation showed that there were significant differences in the color, taste and overall quality of the samples(p<0.05), but there were no significant differences in odor or texture. With regard to the mechanical properties of the samples, we noted significant differences in he Hardness, Cohesiveness, Gumminess and Chewiness of the samples(p<0.05), but no differences in springiness were detected. The luminance of the black Ginseng Dasik was significantly less than that of the red, white, and control samples(p<0.05), We noted significant differences in Hunter's b values, but no significant differences in Hunter's a values among the samples were detected. No significant differences in the general compositions of the samples were noted. In conclusion, red Ginseng Dasik among the samples evaluated herein, has the most commercial value.

This study was conducted to define the effects of color of polyethylene (P.E.) net shading on the meteorological conditions under the shading growth status, photosynthesis and saponin contents of ginseng plant. Red and blue polyethylene net shading (4 fold) showed a good light intensity of ginseng growth, but red one not only increased air temperature but also resulted in early defoliation. Photosynthetic rate of ginseng leaves was increased in order of red, blue and black shade, Root yield and saponin contents were significantly increased red and blue net as compared with those of common straw shading. Blue color appeared to be most recommendable.

홍삼 추출물(5종)과 흑삼 추출물(2종)과 중국산 인삼 추출물(9종)의 말톨 정성, 지방산 조성비, 페놀성 화합물 함량을 분석하고, 이를 패턴 분석하여 특징적 요인을 정하고, 이를 통해 추출물의 정성 분석에 대한 가능성을 측정하였다. TLC를 이용한 maltol의 분석에서 백삼 추출물은 모두 불검출, 홍삼 흑삼 추출물은 모두 검출되어 말톨의 검출 여부는 정성 분석을 위한 특징적 요인으로 볼 수 있었다. 지방산 조성의 경우 palmitic과 linoleic acid가 인삼 추출물의 주요 지방산이었고, palmitic은 백삼, linoleic 은 홍삼 추출물이 높게 나타났다. 이 두 지방산의 조성을 비교한 비율Pal/Lin)의 경우 백삼 추출물에서 56.7~64.3%, 홍삼 추출물에서 32.0~38.5%로 두 값의 차이가 크게 나타나, 이 수치 역시 분석을 위한 특징적 요인으로 볼 수 있었다. 페놀성 화합물의 경우 추출물 속에서 maltol, caffeic acid, syringic acid, p-coumaric acid, ferulic acid와 cinnamic acid의 존재를 확인 할 수 있었다. 백삼 추출물은 페놀성 화합물이 비슷한 비율로 존재하는 패턴을 보였지만, 홍삼 추출물은 말톨의 함량비가 크게 높았다. 페놀성 화합물 중 maltol과 cinnamic acid의 비율을 측정한 결과, 백삼 추출물에서는 5이하의 수치가 나온데 비해 홍삼 흑삼 추출물에서는 53~289의 수치를 보여 이 역시 정성 분석을 위한 특징적 요인으로 판단되었다. 실험 결과에 의해 선정된 Pal/Lin 비율과 maltol/cinnamic acid 비율과 같은 특징적 요인을 통해 인삼 추출물에 대한 정성 분석의 가능성을 확인할 수 있었다.

This study evaluated cholineresterase inhibitory activity of Korean white ginseng extract (WGE), red ginseng extract (RGE), and black ginseng extract (BGE) and the cholinergic effect on scopolamine (SCOP)-induced amnesic mice. WGE, RGE, and BGE inhibited acetylcholineserase (AChE), as well as butyrylcholineserase (BuChE) in a concentration-dependent manner. BGE presented strong inhibition of AChE with an $IC_{50}$ value of 1.72 mg/mL, followed by WGE (5.89 mg/mL), RGE (6.30 mg/mL), respectively. The inhibitory activity of the three ginseng extracts on BuChE showed similar values among the groups. To better understand the mechanisms of the possible effect of ginseng extract on the cholinergic function, this study assessed the expression of the cholinergic markers of choline acetyltransferase (ChAT) and AChE using western blot and RT-PCR analysis in the brains of amnesic mice. Treatment with ginseng extracts led to inhibition of AChE expression and, the activation of ChAT expression in the hippocampus and the cerebral cortex of amnesic mice as induced by SCOP. The results suggest that ginseng extracts including BGE, appear to modulate the metabolism of acetylchoine (ACh), which would greatly increase synaptic ACh levels and most potently revert SCOP-induced amnesia.

In order to investigate whether the particles reduced to almost nano grade might affect the chemical and physical properties of organic materials, whole Korean Black-Red Ginseng was pulverized into almost nano size and then ginsenosides, minerals, carbohydrates, lipids and proteins in the ultrafine particles were compared with those in the regular particles as control. The mean size of the ultrafine particles was in the 350 nm range, while that of the regular particles was $127{\mu}m$. More ginsenosides, minerals, carbohydrates, lipids and proteins were detected in the ultrafine particles than in the regular particles. Interestingly, more lipids from the ultrafine particles dissolved in the water than those from the regular particles in the ethanol. Absorption and transport of carbohydrate, lipid or antioxidant activity across the intestinal wall using everted intestine sacks of mice was also enhanced by particle size reduction at the almost nano scale. More cytotoxic effect against hepatoma cell growth by ultrafine particles was also found. These results could be used as the basic data for the understanding and evaluation of the effects of organic nanomaterials on the human health.

Black-red ginseng (BRGP) exhibits more potent biological activities than white and red ginseng. However, the effect of BRGP on allergic inflammation has not been studied extensively. In this study, we attempted to evaluate the effects of BRGP on allergic inflammation in vitro and in vivo. The effects of BRGP on pro-inflammatory mediators in phorbol myristate acetate (PMA) and A23187-stimulated human mast cells (HMC-1) and on trimellitic anhydride (TMA)-induced atopic dermatitis-like skin lesions in BALB/c mice were evaluated. BRGP suppressed the expression of $TNF-{\alpha}$, IL-6 and IL-8 from HMC-1 stimulated with PMA and A23187. Furthermore, the oral administration of BRGP markedly significantly reduced apparent severity of atopic dermatitis-like skin lesions, ear swelling, lymph node weight gains and serum IgE levels induced by TMA in mice. BRGP treatment also ameliorated epidermal hyperplasia and infiltration of inflammatory cells including mast cells. Taken together, BRGP possesses significant anti-atopic efficacy, suggesting that it could be used as a potential therapeutic agent for allergic inflammatory diseases, including atopic dermatitis.

This study was conducted to investigate changes in composition of ginsenosides and color of processed ginsengs prepared by different steaming-drying times. Processed ginsengs were prepared from white ginseng with skin by 9-time repeated steaming at $96^{\circ}C$ for 3 hours and followed by hot air-drying at $50^{\circ}C$ for 24 hours. As the times of steaming processes increased, lightness (L value) decreased and redness (a value) increased in color of ginseng powders. Crude saponin contents and ginsenosides compositions in processed ginsengs prepared by different steaming-drying times were investigated using the HPLC method, respecively. Crude saponin contents according to increasing steaming-drying times decreased in some degree. In the case of major ginsenosides, the contents of $Rb_1$, $Rb_2$, Rc, Rd, Rf, Re, $RG_1$, Re were decreased with increase in steamimg times, but those of $Rh_1$, $Rg_3$, $Rk_1$ were increased after especially 3 times of steaming processes. Interestingly, in black ginseng were prepared by 9 times steaming processes, the content of ginsenoside $Rg_3$ was 8.20 mg/g, approximately 18 times higher than that (0.46 mg/g) in red ginseng. In addition, the ratio of the protopanaxadiol group and protopanaxatiol group (PD/PT) were increased from 1.9 to 8.4 due to increasing times of steamming process.

This study involved the production of specialty lager beers supplemented with Korean red ginseng extracts or Bokbunja (Korean black raspberry, Rubus coreanus Miquel) juice. The effects of the Korean red ginseng extracts or Bokbunja juice on the specific gravity, pH, yeast viability, free amino nitrogen content, reducing sugar content, color, alcohol content, turbidity, and sensory evaluation were evaluated. The alcohol content of the beers containing the extracts or juice were within the standard alcohol amounts (3.63-4.0%, v/v). The pH values of the three samples containing Bokbunja juice were lower than that of the control values. The sensory evaluation showed that the addition of Bokbunja juice was superior to the ginseng extracts, and the optimal addition time was before or after the secondary fermentation. These data indicate that the flavor and odor of the Bokbunja juice are more persistent than that of the ginseng extracts.
