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.

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 : Zizyphus jujuba fruits(ZJF), a traditional Korean medicine has various biological activities such as anti-inflammatory, anti-oxidative and neuro-protective effects. However, it is still unclear whether ZJF has any biological effect on anti-aging. In this study, we examined the effect of ZJF on lifespan and thermal stress in C. elegans. Methods and Results : ZJF water extracts were fermented for 7 days(F7-ZJF) and 14 days(F14-ZJF) by Laetiporus sulphureus to increase secondary metabolites such as aglycone of flavonoids and terpenoids. In the lifespan assay, ZJF water extracts and fermented ZJF were treated on the agar medium plate with age synchronized egg stage of C. elegans. Treatment of F7-ZJF-$200{\mu}g/mL$ with OP-50 E. coli and F14-ZJF-$200{\mu}g/mL$ with OP-50 E. coli significantly increased life span of C. elegans(N2) at thermal stress condition of $25^{\circ}C$. Moreover mRNA levels of lifespan associated HSP 16.1, HSP 70, and HSF-1 were increased at thermal stress condition of $25^{\circ}C$. However, in the equilibration temperature of $20^{\circ}C$ after stress condition of $35^{\circ}C$ for 2 hr, F-14-ZJF-$200{\mu}g/mL$ treatment decreased the levels of heat shock protein in hsp16.2/GFP C. elegans. Conclusions : Our study indicates that prolong role of fermented-ZJF in C. elegans is mediated by control HSPs production.

We have previously found that mycelia culture broth of eight kinds of traditional herbal extracts fermented with Phellinus linteus (previously named as 8-HsPLCB) not only inhibited melanin and tyrosinase activity, but also reduced the contents of melanogenesis-related proteins, including tyrosinase and microphthalmia-associated transcription factor, in 3-isobutyl-1-methylxanthine-stimulated B16F0 melanoma cells. For a further study, the effect of 8-HsPLCB against skin pigmentation in brown guinea pigs with ultraviolet B (UVB)-induced hyperpigmentation was investigated. 8-HsPLCB (3%) and arbutin (2%) as positive controls were applied topically twice daily for 4 weeks to the hyperpigmented areas. 8-HsPLCB showed skin-lightening effect as effective as arbutin, one of the most widely used in whitening cosmetics. Melanin index values as the degree of pigmentation showed a significant reduction week by week post 8-HsPLCB treatment and then substantially reduced by 4 weeks. The degree of depigmentation after 4 weeks of topical application with 8-HsPLCB was 32.2% as compared with before treatment (0 week). Moreover, using Fontana-Masson staining and hematoxylin-eosin staining, 8-HsPLCB reduced melanin pigmentation in the basal layer of the epidermis and epidermal thickness changes exposed to the UV-B irradiation as compared with non-treatment and vehicle treatment. The intensity of the skin-lightening effect of 8-HsPLCB was similar to arbutin. These results suggest that the skin-lightening effect of 8-HsPLCB might be resulted from inhibition of melanin synthesis by tyrosinase in melanocytes. To conclude, 8-HsPLCB treatment showed reduction of the melanin pigment and histological changes induced by UV irradiation in brown guinea pigs.

To enhance the physiological activity of the Rhynchosia volubilis (RV), R. volubilis (RVHE-A) and R. volubilis-added herbal powder (RVHE-B) were fermented with a solid state culture of Hericium erinaceum mycelia (HE). The total isoflavone contents of the non-fermented RV-A ($489.9{\mu}g/g$) and RV-B ($571.1{\mu}g/g$) were remarkably increased in fermented RVHE-A ($1,836.4{\mu}g/g$) and RVHE-B ($1,276.7{\mu}g/g$). In particular, aglycone isoflavones such as daidzein and genistein were significantly higher in the RVHE-A than any other sample. When hot-water (HW) and EtOH extracts (E) were fractionated from the RV and RVHE, both extracts from the RVHE-A were higher than those from the RV-A in total polyphenol and flavonoid contents. However, the RVHE-B-HW showed a lower polyphenol and flavonoid content level than did RV-B-HW. RVHE-A-HW and -E also had more potent ABTS radical scavenging activity than any extract from the non-fermented RV and other ferments (RVHE-B). In the meanwhile, RVHE-A-HW potently stimulated the production of macrophage activation-related cytokines such as $TNF-{\alpha}$, IL-6 and IL-12 ($841.7{\pm}71.3pg/mL$, $3.9{\pm}0.1ng/mL$, $179.3{\pm}30.2pg/mL$) from peritoneal macrophage more than RV-A-HW ($92.5{\pm}1.5pg/mL$, $0.1{\pm}0.0ng/mL$, $37.4{\pm}5.4pg/mL$) as well as RVHE-B-HW ($557.0{\pm}21.3pg/mL$, $1.8{\pm}0.0ng/mL$, $90.0{\pm}10.0pg/mL$). However, all the EtOH extracts did not show significant activity. In addition, the RVHE-A-HW showed a significantly higher intestinal immune system modulating activity through Peyer's patch and GM-CSF production than did any other extract from RV and RVHE-B. In conclusion, these results suggest that the fermented R. volubilis with H. erinaceum mycelia possesses a possible use as an industrial application as functional food or material.

Background: Astragali radix (A) and Lithospermi radix (L) have long been used as traditional medicines due to their known anti-inflammatory effects. This study aimed at evaluating, their optimal mixing ratio and their functional compounds by investigating the inhibitory effects of mixed extracts of A and L and their active compounds on matrix metalloproteinases (MMPs). Methods and Results: A and L extracts were obtained by extraction at $80^{\circ}C$ using 50% and 70% fermented alcohol, respectively, and then mixed at a ratio of 5 : 5, 6 : 4, 7 : 3 and 8 : 2 (w/w). The activities of MMP-1, MMP-3, and MMP-13 were evaluated in interleukin-1beta ($IL-1{\beta}$)-induced SW1353 cells. The extract mixtures showed synergistic inhibitory effects on MMP-3 and MMP-13, higher than the effects of the individual A and L extracts. The 7 : 3 mixture (ALM16) showed the most effective MMPs inhibitory activity, while among the active ingredients, calycosin-7-O-${\beta}$-D-glucoside and lithospermic acid exhibited excellent MMPs inhibitory activity. Additionally, an HPLC method was established for simultaneous quantification of the effective components of the extract mixtures, and validated by measuring the linearity, precision and accuracy of the limit of detection (LOD) and limit of quantification (LOQ). Conclusions: ALM16 showed the most effective MMPs inhibitory activity. Calycosin-O-${\beta}$-D-glucoside, calycosin and lithospermic acid were identified as useful candidates, as they were the major functional compounds in the MMP inhibitory activity. Summarily, ALM16 might be a highly effective in osteoarthritis management, owing to its because it exhibits a protective effect on cartilage via excellent inhibition of MMPs.

The principal objective of this study was to compare and analyze the qualitative properties of MLT (mulberry leaf tea) and FMLT (fermented mulberry leaf tea) on the basis of the anti-cancer and anti-allergy activities of various extracts. The inhibitory effect against S-180 solid cancer in vivo were measured as 16.67% for FMLT and 17.78% for MLT. When the anti-allergy effects of the extracts of MLT and FMLT were evaluated, the hot water extract was shown to block histamine secretion more effectively than the ethanol extract for both groups. Furthermore, when the levels of the inflammatory cytokine of HMC-1 were measured, the ethanol extract was found to inhibit the inflammatory cytokine more effectively than the hot water extract, and the FMLT group was more effective than the MLT group.
