Comparative effects of phosphine fumigation and gamma irradiation were evaluated on the qualities of white ginseng prepacked in a commercial laminated film in terms of water absorption, Hunter color parameters(L, a, b) and organoleptic properties(overall color/appearance, flavor) during 6 months of storage at ambient(20oC, 70% RH) and accelerated(40oC, 90% RH) conditions. Moisture content of packed white ginseng(initial 8.44%) linearly increased with storage period, thereby reaching to about 10% (r=0.9966) in ambient and more than 15%(r=0.9886) in accelerated conditions, respectively, at the 6th month of storage. The storage at severe conditions resulted in remarkable changes in Hunter's color values, decrease in whiteness(L) and increase in redness(a) and yellowness(b), while both treatments, phosphine and irradiation less than 5kGy, did not cause any significant changes in color parameters. Phosphine fumigation was shown detrimental to overall flavor of white ginseng(p<0.01), however or ganoleptic qualities of stored samples were effectively maintained by irradiation less than 5kGy(p< 0.05). As the index on the guality of white ginseng stored at severe conditions its organoleptic quality was highly correlated with moisture content(r= 0.9777) and Hunter color values(over 0.9), suggesting the critical values of 15.5% moisture and 72.56, 7.15, 21.45 in Hunter's L, a, b values, respectively.

This study evaluated the anti-cholinesterases (ChEs) and antioxidant activities of white ginseng (WG) and black ginseng (BG) roots of Panax ginseng (PG), P. quinquefolium (PQ), and P. notoginseng (PN). Ginsenosides $Rg_1$, Re, Rf, $Rb_1$, Rc, $Rb_2$, and Rd were found in white PG, whereas Rf was not found in white PQ and Rf, Rc, and $Rb_2$ were not detected in white PN. The major ginsenoside content in steamed BG including $RK_3$, $Rh_4$, and 20(S)/(R)-$Rg_3$ was equivalent to approximately 70% of the total ginsenoside content. The WG and BG inhibited acetylcholinesteras (AChE) and butyrylcholinesterase (BChE) in a dose dependent manner. The efficacy of BG roots of PG, PQ, and PN on AChE and BChE inhibition was greater than that of the respective WG roots. The total phenolic contents and 2, 2-diphenyl-1-picryl-hydrazyl (DPPH) scavenging activity were increased by heat treatment. Among the three WG and BG, white PG and steamed black PQ have significantly higher contents of phenolic compounds. The best results for the DPPH scavenging activity were obtained with the WG and BG from PG. These results demonstrate that the steamed BG roots of the three studied ginseng species have both high ChEs inhibition capacity and antioxidant activity.

방사선에 의해서 유도된 간 손상에 대한 백삼과 발효인삼추출물의 보호효과를 비교 연구하였다. ICR계 생쥐에게 코발트-60 감마선의 5Gy조사 7일 전부터 백삼과 발효인삼추출물(150mg/kg/day)을 각각 투여하였다. 대조군은 생리적 식염수를 투여하고 방사선조사군은 생리적 식염수를 투여하면서 5Gy를 조사하였다. 그리고 각각의 실험군에서 간조직의 $H_2O_2$, catalase, MDA를 측정하였다. 그 결과 방사선조사군과 보다 백삼과 발효인삼추출물 투여군에서 catalase함량이 유의성 있게 증가하여 간의 보호효과가 있었으며 $H_2O_2$와 MDA함량도 유의성 있게 감소하였다. 백삼과 발효인삼이 간 조직에 대한 방사선조사로 부터 매우 우수한 방호제라고 할 수가 있다.

In our previous study, ethylacetate fraction of white ginseng (root of Panax ginseng C.A. Meyer) extract inhibited mushroom tyrosinase activity and melanin production in melanocytes. This study examined its effects on the expression of melanin biosynthesis-related enzymes to explore the depigmenting pathway. Moreover, depigmenting effect on animal skin was examined using UV-B induced hyperpigmented skin of brown guinea pigs. The ethylacetate fraction of the white ginseng extract exhibited depigmenting activity in the skin of brown guinea pig without visible edema. In addition, this fraction reduced tyrosinase expression in melanocytes. The results suggested that ethylacetate fraction of white ginseng extract might be used as skin depigmenting material by inhibition of tyrosinase activity and expression.

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.

Color characteristics were investigated for white ginseng powder immediately and during storage following treatments of gamma ray or ethylene oxide (EO) for microbial decontamination. The variation in fatand water-soluble pigments of the sample was negligible immediately after both treatments, however an apparent increase was observed in the samples stored for four months at $25^{\circ}C$ and RH 90%, in the order of nontreated control, EO-fumigated, and 5 key-irradiated samples. Hunter's color a and b values of white ginseng powder increased slightly in proportion to irradiation doses, whereas EO fumigation caused a decrease in L value and an increase in a and b values of the sample, showing overall color difference (${\delta}^E$) of 1.8. Considering the higher ${\delta}^E$ in the higher RH conditions, airtight packaging and sterilization using like gamma ray were considered an effective means for maintaining high quality of color characteristics in stored white ginseng powder.

본 연구에서는 백삼 및 홍삼 추출물과 그 효소 가수 분해물을 제조하고 이를 첨가하여 제조된 양갱의 항산화 활성 및 품질 특성을 조사하였다. 백삼과 홍삼 추출물의 효소 가수분해를 위해서는 Rapidase C80 max, Pyr-flo, Ultimase MFC를 선정하였다. Rapidase C80 max, Pyr-flo, Ultimase MFC로 가수분해 한 백삼과 홍삼에서는 효소반응 전에는 검출되지 않았던 ginsenoside F2와 Compound K (CK)가 검출되었으며 특히 홍삼의 2차 효소 반응군에서 CK의 함량이 가장 높았다. 효소 가수분해 전 또는 후의 백삼 및 홍삼을 함유한 양갱을 제조한 후 폴리페놀 함량, 항산화 능력을 분석한 결과 백삼 및 홍삼을 함유하지 않은 양갱(대조군)에 비해 총 폴리페놀 함량, DPPH 라디칼 소거능, ABTS 라디칼 소거능, FRAP 분석 결과 모두 우수하였으며, 첨가한 백삼 및 홍삼에 효소반응을 진행할수록 유의적으로 항산화 활성이 증가하였다(P<0.05). 밝기(L^*)는 무첨가 양갱(대조군)이, 적색도(a^*)는 홍삼양갱(RG)이, 황색도(b^*)는 백삼양갱(WG)이 높게 나타났고, 조직감은 홍삼 첨가 후 2차 가수분해까지 진행한 양갱(RG-T2)이 강도(hardness), 탄력성(springiness), 씹힘성(chewiness), 응집성(cohesiveness), 검성(gumminess) 모두 유의하게 높은 결과를 나타내었다(P<0.05). 결론적으로, 백삼 또는 홍삼 추출물에 Rapidase C80 max, Pyr-flo, Ultimase MFC를 처리하면 진세노사이드 탈당화에 매우 유용하여 생리활성이 우수한 CK를 생산할 수 있으며, 효소로 가수분해 된 백삼 및 홍삼을 첨가한 양갱은 대조군(인삼 무첨가 양갱)에 비해 총 폴리페놀과 항산화 활성을 유의하게 증가시킨다는 것을 알 수 있었다. 이러한 결과는 향후 기능성 양갱 제조에 우수한 기초자료로 활용될 수 있을 것으로 보인다.

Objectives : The purpose of this study was to investigate anti-cancer effects of various ginseng herbal acupuncture in mice and expression of cytokine mRNA. Methods: Anti-cancer effects of various ginseng herbal acupuncture were tested by measuring the increase of life span of mice suffering from peritoneal cancer induced by Sarcoma-180, and expression of mRNA manifestation using RT-PCR. The results are as follows: Results: 1. Increase of life span of mice suffering from peritoneal cancer induced by Sarcoma-180 was measured for anti-cancer effects. As a result, 115% increase was shown in the cultivated wild ginseng group, 11.1% increase in the red ginseng group, and no increase was detected in either white ginseng and fresh ginseng groups. 2. Measuring the expression of cytokine mRNA manifestation, expression of $interferon-{\gamma}$ was slightly increased in the cultivated wild ginseng group compared to the control group, but manifestation of interleukin-10 was slightly decreased. 3. For the red ginseng, white ginseng, and fresh ginseng experiment groups II, IL-2, IL-4, $INF-{\gamma}$, and IL -10 all showed increase suggesting possible error occurring during the test process. Conclusion: From the results obtained in this study, we can reason that the ginseng we use may not match the ginseng cited in the texts of the past. Anti-cancer effects of cultivated wild ginseng can be more potent than those of white and fresh ginseng.
