Objectives : We investigated the anti-aging effects on skin with 9 Repetitive steaming and fermenting herbal composition extract (FHE). Methods : Herbal composition is comprised of Panax Ginseng, Rehmannia glutinosa, Polygonum multiflorum and Polygonatum Sibiricum. They steamed and fermented with Saccharomyces cerevisiae and Lactobacillus brevis by turns at 9 times. We measured various effects related to skin aging such as scavenging activity against free radical, cell proliferation, collagen synthesis and toxicity of 9 repetitive steaming and fermenting herbal composition extract were evaluated and compared with herbal composition extract (HE). Results : As the number of steaming and fermenting cycle increased free-radical scavenging activity were increased. But cell proliferating ratio was not increased when the number of steaming and fermenting cycle. The FHE could significantly increase the collagen synthetic ratio compared with HE treated group. And, FHE was showed no toxicity at all tested concentrations. Conclusions : The results of our study propose that FHE has good anti-aging effects on skin.

Background: Ginseng (Panax ginseng) is a widely used traditional herbal supplement that possesses various health-enhancing efficacies. Various ginseng products are available in market, especially in the Korean peninsula, in the form of drinks, tablets, and capsules. The different ginseng types include the traditional red ginseng extract (RGE), white ginseng, and black red ginseng extract (BRGE). Their fermented and enzyme-treated products are also available. Different treatment regimens alter the bioavailability of certain compounds present in the respective ginseng extracts. Therefore, in this study, we aimed to compare the antioxidant and immune-stimulating activities of RGE, BRGE, and fermented red ginseng extract (FRGE). Methods: We used an acetaminophen-induced oxidative stress model for investigating the reduction of oxidative stress by RGE, BRGE, and FRGE in Sprague Dawley rats. A cyclophosphamide-induced immunosuppression model was used to evaluate the immune-stimulating activities of these ginseng extracts in BALB/c mice. Results: Our results showed that most prominently, RGE (in almost all experiments) exhibited excellent antioxidant effects via increasing superoxide dismutase, catalase, and glutathione peroxidase activities in the liver and decreasing serum 8-hydroxy-2'-deoxyguanosine, aspartate aminotransferase, and lactate dehydrogenase levels compared with the groups treated with FRGE and BRGE. Moreover, RGE significantly increased the number of white blood cells, especially T and B lymphocytes, and antibody-forming cells in the spleen and thymus, and it also activated a number of immune cell subtypes. Conclusion: Taken together, these results indicate that RGE is the best supplement for consumption in everyday life for overall health-enhancing properties.

Objectives : The objective of this study is to evaluate antioxidant activity and the main component content change of steaming-drying fermented Gastrodiae rhizoma extract. Methods : The antioxidant activities were determined for total polyphenol, flavonoid contents, SOD-like activity, electron donating activity, nitrite scavenging ability and major functional components(gastrodin and 4-hydroxybenzyl alcohol content) were also measured. Results : The polyphenol content of fermented Gastrodiae rhizoma by S. cerevisiae were higher than those of fermented Gastrodiae rhizoma by A. oryzae, and when the fermentation period is extended. SOD like activity of fermented Gastrodiae rhizoma showed to be increased by fermentation with S. cerevisiae than fermentation by A. oryzae. Electron donating activity of fermented Gastrodiae rhizoma were increased at almost parallel level as vitamin C, by fermentation. Notably, fermentation by A. oryzae was moderately better than fermentation by S. cerevisiae. Flavonoid content of Gastrodiae rhizoma showed to increasing by fermentation, particularly fermentation by S. cerevisiae was proven to be more effective than by A. oryzae. The more steaming-drying or increased period of fermentation would be resulted in more gastrodin contents but under the same conditions, 4-hydroxybenzyl alcohol content of fermentation by A. oryzae in case of steaming and drying 1 time and 3 time was higher than control. Conclusions : These results has strongly hint the possible applicability of fermentation might be effective to improve the diverse biological activities of Gastrodiae rhizoma and may further supports to develop a functional food materials.

Complex microbial communities play an important role in the human health and co-evolved with human in the form of symbiosis. Many literatures provide new evidences that the increased prevalence of obesity cannot be attributed solely to changes in the human genome, nutritional habits, or reduction of physical activity in our daily lives. The intestinal flora was recently proposed as an environmental factor responsible for the control of body weight and energy metabolism. A number of studies suggest that the modulation of gut microbiota affects host metabolism and has an impact on energy storage and demonstrated a role for the gut microbiota in weight gain, fat increase, and insulin resistance. Variations in microbiota composition are found in obese humans and mice and the microbiota from an obese mouse confers an obese phenotype when transferred to an axenic mouse. As well, the gut microbial flora plays a role in converting nutrients into calories. Specific strategies for modifying gut microbiota may be a useful means to treat or prevent obesity. Dietary modulations of gut microbiota with a view to increasing bifidobacteria have demonstrated to reduce endotoxemia and improve metabolic diseases such as obesity. The fermentation of medicinal herbs is intended to exert a favorable influence on digestability, bioavailability and pharmacological activity of herbal extract. Therefore we also expect that the fermented herbal extracts may open up a new area to treat obesity through modulating gut microbiota.

Angelica tenuissima root has historically been used as a traditional medicine in Korea. Previous studies have identified the anti-melanogenic effects of the extract of A. tenuissima root fermented by Aspergillus oryzae (FAT). This study investigated the protective effects of FAT against ultraviolet light B exposure (UVB; $30mJ/cm^2$) in HaCaT (human keratinocyte) or Hs68 (human foreskin fibroblast) skin cells. FAT treatment was able to stimulate wound healing rate at the basal condition. FAT also favored the maintenance and/or improvement of extracellular matrix impairment caused by UVB irradiation through: 1) upregulation of procollagen Type-1 synthesis and secretion; 2) suppression of MMP-1 and elastase expression. FAT was able to play a role in the attenuation of inflammatory responses caused by UVB irradiation via upregulation of photo-protective hemeoxygease-1 and suppression of proinflammatory cyclooxygenase-2 expression. After further verification of the anti-photoaging potential of FAT, it could be utilized as an effective ingredient in anti-aging and anti-wrinkle cosmetics.

Ginseng (the root of Panax ginseng CA Meyer, family Araliacease), which is used in Korea, China and Japan as a herbal medicine, was fermented with Ganoderma lucidum (GL) and their antiallergic effects were investigated. Of GLs used for fermentation, KCTC 6283 potently produced ginsenoside Rh2, followed by KFRI M101. KCTC 6532, and ginsenoside Rd, followed by KFRI M101. Oral administration of these fermented ginseng extracts inhibited allergic reactions, passive cutaneous anaphylaxis reaction induced by IgE and scratching behaviors induced by compound 48/80. Of them, the ginseng extract fermented by KCTC 6532 and KFRI M101 potently inhibited allergic reactions compared to that fermented by KCTC 6283. These findings suggest that the fermentation of ginseng with GL can increase its antiallergic activity and the increment of its antiallergic effect may be due to the biotransformation of ginseng saponins to ginsenosides Rd and Rh2.
