The aim of this study was to evaluate the efficacy of red ginseng drinks as school meal drinks for 456 middle and high school students in Cheongdo-gun, North Gyeongsang Province. In preliminary studies, we focused on saponin with an efficacy of Rg 1 and Rg 2 in prepared red ginseng drinks. The health benefits and sensory characteristics were also investigated. For the frequency analysis, the satisfaction of the drinks as beverages serving as a school meal was relatively low, and the demand for fruit drinks was high. The result of sensory evaluations indicated a positive response of > 50.0% for the container packaging and design, daily intake, and tastes. Regarding the correlation analysis on red ginseng drinks, there were significant differences (p < 0.01) in the response to packaging (a daily intake) and design. In addition, health and learning benefits showed a very high correlation at the p < 0.01 significance level.

A chronical intake of Substantial amount of alcohol would disrupt anormal function of liver if not develop liver diseases in relatively short period. In order to out whether ginseng or ginseng plus high protein diet have any protective effects on the liver of chronical alcoholist from developing malfunction enzymatic activities of both glutamic-pyruvic and glutamic-oxaloacetic transaminases were measured on serum of rats maintained with basal low protein diet, basal diet plus 1 percent ginseng and high protein (40%) plus 1 percent ginseng and administered intraperitoneally with a Constant amount of ethanol either periodically or chronically. It was found that, unlike human subject GOT content was exceedingly high and significant difference was found either among treatment or among sexes thus indicating that either ginseng intake or high protein diet plus ginseng has a protective effect on the liver function of ethanol treated rats. From these results, it was suggested that the dietary ginseng might, have a protective effect on the alcohol hepatic disturbance. As one of probable mechanisms for the characteristic pharmacological activity, it was considered that a secondary action of the saponin of the dietary ginseng would result in the anti-inflammatory through the stimulation of de nove synthesis of certain functional proteins in hepatic organs.

This study was conducted to investigate the applicability of the ground parts such as flower (GF), berry (GR), and leaf (GL) from Panax ginseng C. A. Meyer. The ground parts were extracted from hot water (WE) and 60% ethanol (EE). Total polyphenol and flavonoid contents were 15.02-32.74 and 21.60-484.05 mg GAE/g, respectively. Hot water extract of ginseng leaf (GLWE) and 60% ethanol extract of ginseng leaf (GLEE) showed higher total polyphenol and total flavonoid contents than other extracts. Crude saponin contents were found in the range of 15.30-37.27%. Antioxidant activity of these extracts from ginseng was also analyzed by DPPH, ABTS, H₂O₂ scavenging activity, reducing power, and inhibition effect on lipid peroxidation. We confirmed the results that hot water extract of ginseng leaf (GLWE), 60% ethanol extract of ginseng leaf (GLEE) has high anti-oxidative effects. According to the antioxidant activity results of each extract of ginseng flower, ginseng berry, and ginseng leaf, it is judged that their availability is very high, and if proper processing is performed, it can be used as a functional raw material.

This study was performed to investigate the antioxidant activity of extracts of black Panax ginseng (BGE) and its crude saponin (BGECS). The antioxidant activities of BGE and BGECS were evaluated for free radical scavenging activity against stable free radical (1,1-diphenyl-2-picrylhydrazyl) DPPH, nitrite, hydrogen peroxide and superoxide. In addition, the antioxidant activity of BGE and BGECS against peroxyl radicals, hydroxyl radicals and peroxynitrites were determined by the total oxy-radical scavenging capacity (TOSC) assay. As a result, BGE and BGECS were found to have a strong inhibitory activity with >90% against the DPPH radical at $1000{\mu}g/m{\ell}$ concentrations. Also, BGE and BGECS exhibited strong inhibitory activity with >80% against hydrogen peroxide at lower concentration ($125{\mu}g/m{\ell}$). Moreover, specific TOSC values (405 and 473 TOSC/mM) of BGE and BGECS against peroxynitrites were higher than GSH (347 TOSC/mM) used a positive control. These results suggest that BGE and BGECS could be useful to develop functional foods against disease related oxidative stress.

Activation tagging that uses T-DNA vectors containing multimerized transcriptional enhancers from the cauliflower mosaic virus (CaMV) 35S gene is a powerful tool to determine gene function in plants. This approach has been successfully applied in screening various types of mutations and cloning the corresponding genes. We generated an activation tagged hairy root pool of ginseng (Panax ginseng C.A. Meyer) in an attempt to isolate genes involved in the biosynthetic pathway of ginsenoside (triterpene saponin), which is known as the major active ingredient of the root. Quantitative and qualitative variation of ginsenoside in activation tagged hairy root lines were profiled using LC/MS. Metabolic profiling data enabled selection of a specific hairy root line which accumulated ginsenoside at a higher level than other lines. The relative expression level of several genes of triterpene biosynthetic pathway in the selected hairy root line was determined by real time RT-PCR. Overall results suggest that the activation tagged ginseng hairy root system described in this study would be useful in isolating genes involved in a complex metabolic pathway from genetically intractable plant species by metabolic profiling.

Cardiovascular diseases prevail among modern societies and underdeveloped countries, and a high mortality rate has also been reported by the World Health Organization affecting millions of people worldwide. Hyperactive platelets are the major culprits in thrombotic disorders. A group of drugs is available to deal with such platelet-related disorders; however, sometimes, side effects and complications caused by these drugs outweigh their benefits. Ginseng and its nutraceuticals have been reported to reduce the impact of thrombotic conditions and improve cardiovascular health by antiplatelet mechanisms. This review provides (1) a comprehensive insight into the available pharmacological options from ginseng and ginsenosides (saponin and nonsaponin fractions) for platelet-originated cardiovascular disorders; (2) a discussion on the impact of specific functional groups on the modulation of platelet functions and how structural modifications among ginsenosides affect platelet activation, which may further provide a basis for drug design, optimization, and the development of ginsenoside scaffolds as pharmacological antiplatelet agents; (3) an insight into the synergistic effects of ginsenosides on platelet functions; and (4) a perspective on future research and the development of ginseng and ginsenosides as super nutraceuticals.

Inflammation is an innate immune response that protects the body from pathogens, toxins, and other dangers and is initiated by recognizing pathogen-associated molecular patterns or danger-associated molecular patterns by pattern-recognition receptors expressing on or in immune cells. Intracellular pattern-recognition receptors, including nucleotide-binding oligomerization domain-like receptors (NLRs), absent in melanoma 2, and cysteine aspartate-specific protease (caspase)-4/5/11 recognize various pathogen-associated molecular patterns and danger-associated molecular patterns and assemble protein complexes called "inflammasomes." These complexes induce inflammatory responses by activating a downstream effector, caspase-1, leading to gasdermin D-mediated pyroptosis and the secretion of proinflammatory cytokines, such as interleukin $(IL)-1{\beta}$ and IL-18. Ginsenosides are natural steroid glycosides and triterpene saponins found exclusively in the plant genus Panax. Various ginsenosides have been identified, and their abilities to regulate inflammatory responses have been evaluated. These studies have suggested a link between ginsenosides and inflammasome activation in inflammatory responses. Some types of ginsenosides, including Rh1, Rg3, Rb1, compound K, chikusetsu saponin IVa, Rg5, and Rg1, have been clearly demonstrated to inhibit inflammatory responses by suppressing the activation of various inflammasomes, including the NLRP3, NLRP1, and absent in melanoma 2 inflammasomes. Ginsenosides have also been shown to inhibit caspase-1 and to decrease the expression of $IL-1{\beta}$ and IL-18. Given this body of evidence, the functional relationship between ginsenosides and inflammasome activation provides new insight into the understanding of the molecular mechanisms of ginsenoside-mediated antiinflammatory actions. This relationship also has applications regarding the development of antiinflammatory remedies by ginsenoside-mediated targeting of inflammasomes, which could be used to prevent and treat inflammatory diseases.

본 연구는 지역특산자원인 우슬과 발아벼를 이용하여 Achyranthes japonica Nakai-Rice Pilsner(ARP) 맥주를 제조하고 얻어지는 맥주박의 활용가치를 평가하여 소규모 맥주 제조사의 부가가치 생산과 제품개발을 위한 기초자료로 활용하고자 수행되었다. ARP 맥주 제조 시 당화 및 농축공정에서 얻어지는 맥주박 brewer's spent grain(BSG, 맥아와 미아)와 brewer's spent material(BSM, 우슬)의 $25^{\circ}C$, $60^{\circ}C$, 그리고 $100^{\circ}C$ 열수 추출액을 제조하고 이들의 영양성 및 기능성을 평가하였다. ARP 맥주박 BSG와 BSM의 열수 추출액의 유용성분 추출량은 추출온도와 시간에 따라 차이를 나타내었으며 ${\gamma}-aminobutyric$ acid(GABA), 사포닌, 나이아신 성분은 $60^{\circ}C$에서 3시간 이상의 추출에서 함량이 높게 나타났지만, 총폴리페놀 성분과 항산화능[1,1-diphenyl-2-picrylhydrazyl(DPPH) 라디칼 소거능 및 환원력]의 경우 $100^{\circ}C$에서 1시간 추출 시 가장 높은 값을 나타내었다. 엽산의 경우 BSG는 $100^{\circ}C$에서, BSM은 $60^{\circ}C$에서 추출된 시료가 높은 함량을 나타내었다. 전체적으로 영양성과 기능성을 모두 고려해볼 때 $60^{\circ}C$에서 3시간의 열수 추출조건이 바람직한 조건으로 보인다. 이 조건하에서 BSG 추출액의 경우 GABA $186.1{\mu}g/100mL$, 나이아신 $67.9{\mu}g/100mL$, 엽산 $80.9{\mu}g/100mL$, 총폴리페놀 $198.8{\mu}g$ gallic acid equivalent(GAE)/100mL, DPPH 라디칼 소거능 $90.0{\mu}g\;GAE/100mL$, 환원력 $8.4{\mu}g\;GAE/100mL$, BSM 추출액의 경우 사포닌 $300.2{\mu}g$ diosgenin equivalents/100 mL, 나이아신 $1,209.7{\mu}g\;GAE/100mL$, 엽산 $18.0{\mu}g\;GAE/100mL$, 총폴리페놀 $270.4{\mu}g\;GAE/100mL$, DPPH 라디칼 소거능 $1,049.9{\mu}g\;GAE/100mL$, 환원력 $505.5{\mu}g\;GAE/100mL$를 보이는 것으로 나타났다. BSM의 열수 추출액은 BSG 추출액에 비하여 수용성 비타민의 경우 약 4~18배, 총폴리페놀 함량은 1.4배, 항산화능은 약 11~60배 높게 나타나 영양성 및 기능성 모두 우수한 것으로 나타났다. 본 연구 결과를 볼 때 ARP 맥주박은 영양성 및 기능성 면에서 우수한 자원으로 $60^{\circ}C$에서 3시간 열수 추출물을 향후 제품 개발에 활용 가능할 것으로 판단된다.

Background: GS-3K8 and GINST, both of which are modified ginseng extracts, have never been examined in terms of their effectiveness for the prevention of acute respiratory illness (ARI) in humans. We conducted a pilot study to assess the feasibility of performing a large-scale, randomized, controlled trial. Methods: This study was a randomized, double-blind, placebo-controlled, pilot study at a single center from October 2014 to March 2015. The 45 healthy applicants were randomly divided into the GS-3K8 (n = 15), GINST (n = 15), and placebo groups (n = 15). The study drug was administered as a capsule (500 mg/cap and 3000 mg/day). GS-3K8 contained 6.31 mg/g of Rg1, 15.05 mg/g of Re, 30.84 mg/g of Rb1, 15.02 mg/g of Rc, 12.44 mg/g of Rb2, 6.97 mg/g of Rd, 1.59 mg/g of Rg3, 3.25 mg/g of Rk1, and 4.84 mg/g of Rg5. GINST contained 7.54 mg/g of Rg1, 1.87 mg/g of Re, 5.42 mg/g of Rb1, 0.29 mg/g of Rc, 0.36 mg/g of Rb2, 0.70 mg/g of Rd, and 6.3 mg/g of compound K. The feasibility criteria were the rates of recruitment, drug compliance, and successful follow-up. The primary clinical outcome measure was the incidence of ARI. The secondary clinical outcome measures were the duration of symptoms. Results: The rate of recruitment was 11.3 participants per week. The overall rate of completed follow-up was 97.8%. The mean compliance rate was 91.64 ± 9.80%, 95.28 ± 5.75%, and 89.70 ± 8.99% in the GS-3K8, GINST, and placebo groups, respectively. The incidence of ARI was 64.3% (9/14; 95% confidence interval [CI], 31.4-91.1%), 26.7% (4/15; 95% CI, 4.3-49.0%), and 80.0% (12/15; 95% CI, 54.8-93.0%) in the GS-3K8, GINST, and placebo groups, respectively. The average days of symptoms were 3.89 ± 4.65, 9.25 ± 7.63, and 12.25 ± 12.69 in the GS-3K8, GINST, and placebo groups, respectively. Conclusion: The results support the feasibility of a full-scale trial. GS-3K8 and GINST appear to have a positive tendency toward preventing the development of ARI and reducing the symptom duration. A randomized controlled trial is needed to confirm these findings.

오늘날 고기 소비가 증가하면서 소비자들은 평범한 식품보다는 질병의 예방 또는 치료 효과가 있는 기능성 식품성분을 요구하게 되었다. 본 연구의 목적은 불고기 양념에 분쇄한 인삼세근을 첨가량에 따라 0%, 0.5%, 1.0%과 2.0%수준으로 첨가하여 돈육 인삼불고기제품을 개발한 다음 인삼첨가수준에 따른 이화학적 및 관능적 제품특성을 무첨가구와 비교하고자 실시하였다. CIE로 측정한 육색에 있어서는 인삼 첨가비율이 증가할수록L값과 b값이 증가하는 경향을 나타내었다. 인삼이 첨가되지 않은 처리구와 비교하여 인삼이 첨가된 처리구의 연도가 낮게 나타났으나 응집성, 탄력성 및 씹힘성에서는 유의적인 차이가 없었다. 관능 평가 결과 인삼첨가 농도가 높은 처리구가 기호도가 더 높은 것으로 나타났다. 가열 조리한 다음 5$^{\circ}C$에서 7일간 냉장 저장하면서 산화도를 측정한 결과 인삼 첨가구가 저장 기간이 증가할수록 무첨가구와 비교하여 낮은 TBA 값을 나타냈다. 지방산 조성은 인삼 2% 첨가한 처리구가 PUFA/SFA 비율이 높게 나타났다. 결론적으로 돈육 불고기 제품에 인삼을 첨가함으로서 육질에 크게 영향을 주지 않으면서 향과 기호도를 증진시켜 일반돈육제품과 차별화된 제품이 될 수 있을 것으로 기대된다. 따라서 본 연구에서 개발한 인삼불고기 돈육가공제품은 우리 나라에서 생산되는 인삼과 국내 비선호부위인 돈육의 전지 및 후지를 적절하게 이용한 것으로서 국제시장에서 돈육 수출 및 소비 확대에 기여할 수 있을 것으로 기대된다.
