A new processed ginseng with fortified activity is developed. The process comprise with the heat treatment of fresh or white ginseng at higher temperature and pressure than those used for the preparation of red ginseng. This new processed ginseng showed 7 times higher antioxidant activity and more than 30 times stronger vasodilating activity than those shown in raw ginseng. Other activities found in the new processed ginseng include cancer chemoprevention, antinephrotoxic, and antineurotoxic activities. Less polar ginsenosides isolated from processed ginseng exhibited anti-platelet aggregation activity and anti-cancer activity. Many ginsenosides were isolated from this new processed ginseng, namely 20(S)-$Rg_3$,20(R)-$Rg_3$, $Rg_5$, $Rg_6$, $F_4$, $Rh_4$,20(S)-$Rg_3$,20(R)-$Rg_3$ and $Rg_4$. In addition to these known compounds, seven new ginsenosides, named as gisenoside $Rk_1$, $Rk_2$, $Rk_3$, $Rs_4$, $Rs_5$, $Rs_6$, and $Rs_7$ were isolated. The major constituents of new processed ginseng were 20(S)-$Rg_3$,20(R)-$Rg_3$, $Rk_1$ and $Rg_5$ which are minors in red ginseng. Since the chemical constituents and biological activities of this new processed ginseng are quite different from those of white or red ginseng, we designated it as $'$sun ginseng (仙蔘)$'$.s;$.

Ginsenoside Rp1 (G-Rp1) is a ginseng saponin derivative with chemopreventive and anti-cancer activities. In this study, we examined the regulatory activity of G-Rp1 on the functional activation of macrophages. G-Rp1 remarkably inhibited TNF-$\alpha$ production, LPS-induced cell cytotoxicity, NO production, ROS generation, and phagocytic uptake from lipopolysacchride (LPS)-activated RAW264.7 cells. According to structural feature study using several G-Rp1 analogs, two carbohydrates (glucose-glucose) at R1 position were observedto be highly effective, compared to other structural derivatives. Although the inhibitory activities of G-Rp1 on macrophage functions were not remarkable, several points that G-Rp1 was known to be safe, and that this compound was orally effective, suggest that G-Rp1 may be beneficial in treating macrophage-mediated immunological diseases.

본 연구는 구중구포법 과정의 흑삼 1~9포를 대상으로 열수 및 70% 에탄올 추출물의 ginsenosides을 분석한 결과 생리 활성이 높다고 판단한 흑삼 5포와 9포 열수 및 에탄올 추출물을 각각 3T3-L1 지방세포, RAW264.7 대식세포, 지방유래 줄기세포에 처치하여 세포독성, 지질축적(adipogenesis) 및 염증인자 변화를 관찰하였다. 본 연구에서는 열수 추출물보다 에탄올 추출물 흑삼에서 효율적으로 ginsenosides가 추출되었다. 또한 흑삼 에탄올 추출물이 $PPAR{\gamma}$ 및 C/$EBP{\alpha}$ 감소, AMPK의 인산화 증가 등 adipogenesis 관련인자를 억제하였으며, 아울러 염증성 사이토카인의 분비를 억제하였다. 따라서 비만 및 대사성 질환의 예방에도 잠정적으로 이용될 수 있을 것으로 기대되지만 ginsenosides와 비만과의 조절기전 연구 및 항염증성 기전 등에 대한 정확한 기전 규명이 필요하다. 현재 인삼에 함유된 ginsenosides를 이용하여 체지방 감소 등의 기능성식품으로 많이 개발되고 있는 현실을 감안해 볼 때 홍삼 및 흑삼의 제조 기술인 구증구포법의 효율적인 표준화 공정기술, 유효 생리활성 성분의 대량 생산 및 안전성 기술 등이 개발된다면 항비만에 대한 고부가 가치 상품개발이 가능할 것으로 기대된다.

압출성형공정을 홍삼화 공정에 적용하기 위하여 수삼을 압출성형하려면 35% 이하로 수삼을 건조하는 전처리가 필요하다. 수삼을 건조하기 위하여 파쇄한 수삼과 뇌두부위와 미근과 세근부위를 제거하고 주근과 지근을 가진 주근수삼으로 각각 전처리하여 건조온도 80, 100, 12$0^{\circ}C$에서 수분함량의 감소속도 및 건조수삼의 이화학적 성질을 분석하였다. 파쇄수삼의 건조온도는 8$0^{\circ}C$에서 건조시간이 35% 이하로 수분을 감소시키는데 6.2시간이 걸리고 생성된 총 진세노사이드의 양도 10$0^{\circ}C$와 12$0^{\circ}C$ 건조보다 낮았으므로 전처리 건조조건으로 적당하지 않았다. 또한 10$0^{\circ}C$와 12$0^{\circ}C$ 건조를 비교할 때 35% 이하의 수분함량으로 걸리는 시간은 5.7시간과 3.5시간으로 12$0^{\circ}C$ 건조조건에서 2시간 정도 단축되었으나 적색도는 5.20에서 7.23으로 1.39배 증가하여 가루의 색깔이 홍삼과 차이가 있었다. 75% 에틸렌으로 추출한 추출액의 갈색과 적색의 반응속도는 건조온도가 증가할수록 유의적으로 증가하였다. 또한 Rb1, Rb2, Rc, Rd, Rg1, 총 진세노사이드 함량 및 정성적으로 측정한 말톨의 양은 10$0^{\circ}C$와 12$0^{\circ}C$ 건조에서 유의적인 차이가 없었다. 그러므로 총 진세노사이드와 말톨 양을 고려할 때 12$0^{\circ}C$보다 10$0^{\circ}C$에서 압출성형 전처리공정으로 수삼을 열풍 건조하는 것이 적당한 것으로 판단되었다.

Fresh (raw roots), white (dried), and red (steamed-drid) ginseng samples were gamma-irradiated at 0 to 7 kGy. Electron spin resonance (ESR) technique was used to characterize the irradiation status of the samples, targeting the radiation-induced cellulose radicals after different sample pretreatments. All non-irradiated samples exhibited a single central signal (g=2.006), whose intensity showed significant increase upon irradiation. The ESR spectra from the radiation-induced cellulose radicals, with two side peaks (g=2.0201 and g=1.9851) equally spaced (${\pm}3mT$) from the central signal, were also observed in the irradiated samples. The core sample analyzed after alcoholic-extraction produced the best results for irradiated fresh ginseng samples. In the case of irradiated white and red ginseng samples, the central (natural) and radiation-induced (two-side peaks corresponding to cellulose radical) signal intensities showed little improvement on alcoholic-extraction. The water-washing step minimized the effect of $Mn^{2+}$, but reduced the intensity of side peaks making them difficult to indentify. The effect of different origins was negligible, however harvesting year showed a clear effect on radiation-induced ESR signals.

Inflammation that is considered to be mainly related to pathogenesis of atopic dermatitis (AD) is the biological response of a host to stimuli, such as cellular injury or infection. In this study, we investigated the anti-inflammatory and anti-oxidative activities of white ginseng roots by ultra high pressure extraction (Gin-UHP), fermentation followed by ultra high pressure extraction (Gin-UHPF), and polyol extraction (Gin-POL). As a result, ginseng extracts were able to decrease the secretion of pro-inflammatory cytokines (interleukin-8 and tumor necrosis factor-alpha) and immunoglobulin E. Also, Gin-POL had the highest DPPH radical scavenging activity and when we compared the SOD-like activity, Gin-UHP had the highest. Moreover, we looked into the effect of these ginseng extracts on anti-aging to show the possible usefulness as a raw material of cosmetics. As a result, ginseng extracts were able to reduce the production of melanin, and inhibit the tyrosinase and elastase activities in a dose-dependent manner. The extracts also decreased the expression of MMP-1 and had a significant hyaluronidase inhibitory activity. Taken together, these results demonstrate that ginseng extracts may have an improvement effect on AD by using its anti-inflammatory and antioxidant properties.

In this study, white ginseng was used as the raw material, which was fermented with Paecilomyces hepiali through solid culture medium, to produce ginsenosides with modified chemical composition. The characteristic chemical markers of the products thus produced were investigated using rapid resolution liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (RRLC-QTOF-MS). Chemical profiling data were obtained, which were then subjected to multivariate statistical analysis for the systematic comparison of active ingredients in white ginseng and fermented ginseng to understand the beneficial properties of ginsenoside metabolites. In addition, the effects of these components on biological activity were investigated to understand the improvements in the phagocytic function of macrophages in zebrafish. According to the established RRLC-QTOF-MS chemical profiling, the contents in ginsenosides of high molecular weight, especially malonylated protopanaxadiol ginsenosides, were slightly reduced due to the fermentation, which were hydrolyzed into rare and minor ginsenosides. Moreover, the facilitation of macrophage phagocytic function in zebrafish following treatment with different ginseng extracts confirmed that the fermented ginseng is superior to white ginseng. Our results prove that there is a profound change in chemical constituents of ginsenosides during the fermentation process, which has a significant effect on the biological activity of these compounds.

It was reported that Red ginseng contains specific ginsenoside-Rg$_2$,-Rg$_3$,-Rh$_1$and -Rh$_2$, which show various pharmacological effects. However, production of these specific ginsenosides from Red ginseng is not commercially applicable because of high cost of the raw material, roots. This work was carried out to examine the production of Red ginseng specific ginsenosides from Agrobacterium-transformed hairy roots. Hairy roots were induced from 3 year-old root segment of Korean ginseng (Panax ginseng C.A. Meyer) after infection with Agrobacterium rhizogenes A4. Among many lines of hairybroots, KGHR-8A was selected. Steam heat treatment of hairy roots was resulted in the changes of ginsenoside composition. Eleven ginsenosides were detected in heat-treated hairy roots but eight in freeze dried hairy roots. In heat treated hairy root, content of ginsenoside-Rb$_1$,Rb$_2$,Rc, Rd, Re, Rf, and Rg$_1$were decreased compared to those of freeze dried hairy roots. However, heat treatment strongly enhanced the amount of Red ginseng specific ginsenogides (ginsenoside-Rg$_2$,-Rg$_3$,-Rh$_1$and -Rh$_2$). Amounts of ginsenoside-Rg$_3$,-Rh$_1$and -Rh$_2$ in heat-treated hairy roots were 2.58, 3.62 and 1.08 mg/g dry wt, respectively, but these were detected as trace amount in hairy roots without heat treatment. Optimum condition of heat treatment for the production of Red ginseng specific ginsenoside was 2 h at 105$^{\circ}C$. This result represents that Red ginseng specific ginsenoside can be producted from hairy roots by steam heat treatment.
