Objectives : The aim of this study was to find optimal conditions for producing red ginseng from cultivated wild ginseng using the Turbo Mill. Methods : Characteristics of powdered cultivated wild ginseng based on various temperature settings of the Turbo Mill were observed, and changes in the content was measured by HPLC for various ginsenosides. Results : 1. The diameter of cultivated wild ginseng powder ground by the Turbo Mill was around 10${\mu}m$. 2. As the temperature rose, pressure, Specific Mechanical Energy(SME), and density decreased, whileas Water Solubility Index(WSI) increased. 3. As the temperature rose, super fine powder showed tendency to turn into dark brown. 4. Measuring content changes by HPLC, there was no detection of ginsenoside Rg3 and ginsenosideRg1, Rb1, and Rh2 concentrations decreased with increase in temperature. Conclusions : Super fine powder of cultivated wild ginseng produced by the Turbo Mill promotes easy absorption of effective ingredients by breaking the cell walls. Using this mechanism to produce red ginseng from cultivated wild ginseng, it yielded less than satisfactory results under the current experiment setup. Further researches are needed to verify more suitable condition for the production of red ginseng.

This study was investigated the changes of quality stability and physicochemical characteristics of the Korean red ginsengs stored for a long times over 20 years. The Korean red ginsengs were stored for 4 to 22 years in canned packaging with polypropylene film and wooden box at room temperatures. The unusal phenomena such as discoloration and pin hole in packaging were not observed. General bacteria showed the vlaues of below 100 CFU/g, coliform groups and molds were not found in any samples stored for 22 year. Any samples also were not detected in mycotoxins. The contents of moisture, ash and crude saponin were the levels of 10.6~11.1%, 3.8~4.2% and 4.1~4.7% during the whole storage periods, respectively. The contents of maltol, which has been known as characteristic flavour and antioxidant of Korean red ginseng, showed remarkably increasing tendency from 0.10 mg/g for 4 years to 2.53 mg/g for 22 years during the storage. The contents of AFG (arginyl-fructosyl-glucose), arginine and free sugar were slightly decreased. Acidic polysaccharide and ginsenoside were not changed significantly during the storage periods. The contents of acidic polysaccharide and total ginsenosides were the 75.1~76.3 mg/g and 15.1~16.6 mg/g, respectively. The sums of ginsenoside-Rg1,-Rb1 and -Rg3s were the ranges of 9.3~9.9 mg/g and PD (ginsenoside-Rb1, -Rb2,-Rc,-Rd,-Rg3s,-Rg3r)/PT (ginsenoside-Rg1,-Rg2,-Re,-Rf,-Rh1) saponin ratios were the levels of 1.4~1.5. These results suggest that Korean red ginsengs stored for long periods show relatively stable quaility stabilities and not significantly changed the contents of ginsenoside and polysaccharide during the storage up to 22 years.

Objectives: Ginseng, Panax ginseng C. A., white ginseng, has been used for thousands of years in Traditional Korean Medicine. Red ginseng can be made by a steaming process of white ginseng changing a variety of ginsenosides and ingredients such as dencichine. This article reviews red ginseng for mechanisms for pharmacodynamics and toxicity based on the content of ginseng's active ingredients, ginsenoside changed by steaming. Methods: The following electronic databases were searched: PubMed, Science Direct and Chinese Scientific Journals full text database (CQVIP), and KSI (Korean Studies Information) from their respective inceptions to June 2012. Results: Compared with unsteamed ginseng, the content of ginsenosides Rg2, Rg3, Rg5, Rh1, Rh2 and Rk1 called red ginseng-specific ginsenosides increased after the steaming process. Different ginsenosides have shown a wide variety of effects such as lowering or raising blood sugar and blood pressure or stimulating or sedating the nervous system. Especially, the levels of Rg2, Rg3, Rg5, Rh1, Rh2 and Rk1 were increased by the steaming process, showing a variety of pharmacodynamics in biological systems. Also, various processing methods such as puffing and fermentation have been developed in processing crude ginseng or red ginseng, affecting the content of ginseng's ingredients. The safety issue could be the most critical, specifically, on changed ginseng's ingredients such as dencichine. The level of dencichine was significantly reduced in red ginseng by the steaming process. In addition, the possible toxicity for red ginseng was affected by cytochrome P450, a herbal-drug interaction. Conclusions: The variety of pharmacological and toxicological properties should be changed by steaming process of Panax ginseng C. A., white ginseng. Even if it is not sure whether the steaming process of white ginseng would be better pharmacologically, it is sure that steaming reduces the level of dencichine causing a lower toxicity to the nervous system.

We reported a new processed ginseng with increased biological activities which is named as “sun ginseng (SG)”. Study on the saponin constituents of SG led to the isolation of seven new ginsenosides named as ginsenoside Rk$_1$, Rk$_2$, Rk$_3$, Rs$_4$, Rs$\_$5/, Rs$\_$6/ and Rs$\_$7/. Ginsenoside Rk$_1$, Rk$_2$ and Rk$_3$ were the Δ$\^$20(21),24(25)/-diene dammarane compounds, while ginsenoside Rs$_4$, Rs$\_$5/, Rs$\_$6/ and Rs$\_$7/ were mono-acetylated compounds. Many other ginsenosides which were reported as minor constituents of red ginseng were also isolated, which include 20(S)-Rg$_3$, 20(R)-Rg$_3$, Rg$\_$5/, Rg$\_$6/, F$_4$, Rh$_4$, 20(S)-Rs$_3$ and 20(R)-Rs$_3$. The major ginsenosides of SG were 20(S)-Rg$_3$, 20(R)-Rg$_3$, Rk$_1$ and Rg$\_$5/.

Thirty-four strains of Lactobacillus species were isolated from soil and eight of these isolates (M1-4 and P1-4) were capable of growing on red ginseng agar. The M1 and P2 strains were determined to be L. plantarum and other strains (M2, M3, M4, P1, P3 and P4) were determined to be L. brevis. Fermentation of red ginseng extract (RGE) with strains M1, M2, P2 and P4 resulted in a low level of total carbohydrate content (174.3, 170.0, 158.8 and 164.8 mg/mL, respectively). RGE fermented by M3 showed a higher level of uronic acid than the control. The polyphenol levels in RGE fermented by M1, P1 and P2 (964.9, 941.7 and $965.3\;{\mu}g/mL$, respectively) were higher than the control ($936.8\;{\mu}g/mL$). Total saponin contents in fermented RGE (except M1) were higher than the control. RGE fermented by M2 and M3 had the highest levels of total ginsenosides (31.7 and 32.7 mg/mL, respectively). The levels of the ginsenoside Rg3 increased from 2.6 mg/mL (control) to 3.0 mg/mL (M2) or 3.1 mg/mL (M3). RGE fermented by M2 and M3 also had the highest levels of Rg5+Rk1 (7.7 and 8.3 mg/mL, respectively). Metabolite contents of ginsenoside (sum of CK, Rh1, Rg5, Rk1, Rg3 and Rg2) of M2 (13.0 mg/mL) and M3 (13.9 mg/mL) were also at a high level among the fermented RGE. Protopanaxadiol and protopanaxatriol content of ginsenoside of M2 (10.9 and 5.4 mg/mL, respectively) and M3 (11.0 and 5.7 mg/mL, respectively) were at higher levels than other fermented RGE.

Background: Red ginseng (RG) is processed from Panax ginseng via several methods including heat treatment, mild acid hydrolysis, and microbial conversion to transform the major ginsenosides into minor ginsenosides, which have greater pharmaceutical activities. During the fermentation process using microbial strains in a machine for making red ginseng, a change of composition occurs after heating. Therefore, we confirmed that fermentation had occurred using only microbial strains and evaluated the changes in the ginsenosides and their chemical composition. Methods: To confirm the fermentation by microbial strains, the fermented red ginseng was made with microbial strains (w-FRG) or without microbial strains (n-FRG), and the fermentation process was performed to tertiary fermentation. The changes in the ginsenoside composition of the self-manufactured FRG using the machine were evaluated using HPLC, and the 20 ginsenosides were analyzed. Additionally, we investigated changes of the reducing sugar and polyphenol contents during fermentation process. Results: In the fermentation process, ginsenosides Re, Rg1, and Rb1 decreased but ginsenosides Rh1, F2, Rg3, and Compound Y (C.Y) increased in primary FRG more than in the raw ginseng and RG. The content of phenolic compounds was high in FRG and the highest in the tertiary w-FRG. Moreover, the reducing sugar content was approximately three times higher in the tertiary w-FRG than in the other n-FRG. Conclusion: As the results indicate, we confirmed the changes in the ginsenoside content and the role of microbial strains in the fermentation process.

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.

경북 풍기지역의 연근별 수삼을 이용한 홍삼제조에 따른 전반적인 품질특성을 분석하였다. 그 결과 5년근 홍삼은 색택, 외관, 직경, 내부품질 등에서 6년 근과 유사하거나 다소 저조하였으나, 길이와 수율 면에서는 우수한 것으로 나타났다. 또한 홍삼의 유효성분인 ginsenoside 함량은 5년 근이 홍삼의 특이성분이라고 할 수 있는 ginsenoside $Rg_3$ 및 $Rh_2$ 함량이 더 높은 것으로 나타났다. 따라서 경북 풍기지역의 홍삼제조에 있어서는 5년 근 수삼을 원료삼으로 사용하는 것이 전반적인 품질 및 유효성분 측면에서 매우 타당한 것으로 평가되었다.

산양삼의 연근별 특징을 분석한 결과 3년근에서는 ginsenoside 등의 성분이 활발하게 생성되고, 연령이 늘어갈 수록 부피 성장이 중점적으로 일어나는 것으로 나타났다. 또한 산성다당체 함량, 총 페놀 함량, 총 플라보노이드 함량 및 항산화능 모두 3년근 산양삼이 다른 연근보다 유의적(p<0.05)으로 높은 결과 값을 나타내었다. 결과적으로 3년근의 경우 단위 중량당 더 많은 양의 성분들을 가지고 있으므로 파종 후 장기간 재배보다는 단시간에 수확하는 것이 재배를 하는 임업인이나 제품을 개발하는 기업인 모두에게 유리 할 것으로 판단된다. 따라서 ginsenoside의 함량 및 다른 생리활성 성분들의 양으로 연근별 산양삼의 특징을 비교 할 경우 비록 부피는 작지만 가격이 싸고 개체수가 많은 3년근을 이용하여 제품을 개발하는 것이 산업적으로 이득이 될 수 있을 것으로 판단된다. 본 연구의 결과는 평창산 산양삼에 한정된 항산화 결과로서 국내 다른 지역에서 자생하는 연근별 산양삼에 대한 세부적인 기능성 연구가 추가적으로 필요한다.
