Agaricus blazei Murill (Almond mushroom) has many beneficial effects, such as anti-cancer, immuneenhancement, and anti-obesity. Also, its skin benefits have been reported for antioxidant, anti-inflammatory, and whitening. In order to elucidate these effects, many studies have been conducted. In this study, we reconfirmed the skin efficacy of the extract of the mushrooms mushrooms. The Agaricus blazei extract showed inhibition of melanin synthesis, enhancement of collagen synthesis, and up-regulation of gene expression (hyaluronan syntahase-2, 3 and aquaporin-3) at 100 ㎍/mL. and identified the ingredients from the extract. We further investigated them to find an applicability as cosmetic ingredients. The ingredients were confirmed comparison of their spectroscopic data with literature values. They were identified as being ergosterol (1), 5-dihydroergosterol (2), cerevisterol (3), cerebroside B (4), cerebroside D (5), adenosine (6), and benzoic acid (7). Among these compounds, we evaluated skin efficacy for two cerebrosides and three ergosterol derivatives that have not been reported its efficacy. As a result, 5-dihydroergosterol (2) inhibited melanogenesis in B16F10 and promoted collagen biosynthesis in human dermal fibroblast. In addition, cerevisterol (3), cerebroside B (4), and cerebroside D (5) inhibited NO production in RAW 264.7 cell. In particular, cerebroside D (5) increased the expression of hyaluronan synthase-2 and aquaporin-3 genes in HaCaT. These results suggest that Agaricus blazei extract and isolated compounds can be used as cosmetic ingredients.

The skin is continuously exposed to environmental stresses. One of the most important stress factor is UV radiation. UV radiation causes a variety of biological effects on the skin, including inflammation, pigmentation, photoaging and cancer. Therefore in this study, we tried to search for skin-protective antioxidant materials from marine natural products (Porphyra Thalli, Laminariae japonicae thallus, Ostreae Concha, Sargassum Thallus, Undaria thallus, Haliotidis Concha, Agar, Codium thalli, Hizikia fusiforme thalli; HFE, Thalli) which exhibit protective activities against UVB-induced cytotoxicity and oxidative cell death and antiaging effects. As a results, UVB-induced cytotoxicity and cell death were effectively suppressed by treatment of Sargassum Thallus, Agar, Haliotidis Concha, Codium thalli, Thalli ethanol extracts. UVB-induced cell death was mediated by intracellular accumulation or ROS, which was significantly inhibited by treatment with marine natural products extracts. Also, The protective effect of these marine natural products seemed to be mediated by increased expression of type I collagen and Type I procollagen. These results suggest that marine natural products may have anti-aging effects new functional materials against oxidative stress-mediated skin damages.

Selaginella tamariscina with the popular Korean name Keoun Back, is a traditional medicinal plant for therapy of advanced cancer patients in the Orient. In this study, we evaluated anti-aging activity of S. tamariscina using processed technology and investigated diverse biological activities of processed S. tamariscina (PST) as an anti-aging ingredient of cosmetics. PST, heated with sand, used to different purpose compared with origin in medicine. PST raises total phenol concentration and enhances the DPPH radical scavenging activity. For testing intracellular ROS scavenging activity, the cultured human dermal fibroblasts were analyzed by increase in dichlorofluorescein (DCF) fluorescence upon exposure to UVB $20 mJ/cm^2$ after treatment of PST. UVA-induced MMP-1 expression in human dermal fibroblasts was reduced in a dose-dependent manner by PST. Taken together, 4hese results suggest that PST may act as an anti-aging agent by preventing the skin cell from damage induced by UV irradiation, and imply that PST may be useful as a new ingredient for anti-aging cosmetics.

Traditionally, the thorns of Gleditsia sinensis LAM. (GS) have been used for the treatment of various types of cancer and heart, skin, vascular and inflammatory diseases. However, there have been no reports on the antinociceptive or antiinflammatory properties of the thorn of GS. The present study was carried out to evaluate the anti-inflammatory and antinociceptive effects of the ethanolic extract of GS (EEGS) and its sub-fractions. The administration of EEGS (500 mg/kg) or its butanolic fraction (50 and 100 mg/kg) reduced the frequency of the acetic acid-induced writhing reflex in mice. In addition, the administration of the butanolic fraction of EEGS (50 and 100 mg/kg) prolonged the latency of reaction at the hot plate in mice. The butanolic fraction of EEGS also inhibited lipopolysaccharide-induced nitric oxide, prostaglandin $E_2$, and tumor necrosis factor-$\acute{a}$ production in the RAW 264.7 cell line. These results suggest that EEGS has anti-inflammatory and analgesic properties and is a potential therapeutic for inflammation and nociception.

This study aimed to improve the production of bioactive materials with antioxidant activity using a fermented Luffa aegyripia extract and improve the anticancer effect by enhancing UV absorption and inhibiting melanoma cell growth. The total phenolic content (TPC) and antioxidant activity of the fermented extract were 30.23 mg GAE/g DM and 45.12%, respectively, which was 1.4 times higher than that of the hot-water extract (HWE). The fermented extract showed a UV adsorption rate of 53.9%, which was 1.5 times higher than HWE, and it was concluded that UV absorption was increased by TPC, which was increased through the fermentation of L. aegyptiaca extracts using Lactobacillus. In the anticancer effect test, fermented and HWE extracts had carcinogenic effects of 1.0 and 2.0 mg/mL, respectively. This suggests that the increased antioxidant activity due to the increase in TPC caused by fermentation contributed to the anticancer effect. The UV absorption rate of fermented extracts was 2.4 times higher than HWE, giving them potential use as cosmetics and pharmaceutical materials with high polyphenol contents and antioxidant properties and skin cancer prevention.

Glycyrrhizae radix, commonly known as licorice, is a perennial herb belonging to Leguminosae and also includes various components such as, glycyrrhizin, liquiritin, liquiritigenin and isoliquiritigenin etc. Licorice has been widely used in East Asia as a medicine having pharmacological effects like antioxidants, anti-bacterial, anti-inflammatory, anti-cancer and immune modulatory activities. Among various licorice, Glycyrrhiza (G.) uralensis G. glabra and G. inflata are used for pharmaceutical purposes in Korea. However, cultivation of licorice has some problems such as low quality, low productivity, and early leaf drop. Korea Rural Development Administration developed new cultivars Wongam and Sinwongam, which are improved in cultivation and quality. To register the newly developed cultivar (s) on Ministry of Food and Drug Safety in Korea as a medicine, it is necessary to prove the similarity and difference through the comparative studies between already-registered species and new cultivars. Some fungi and bacteria usually in the human oral cavity and intestines exist as harmless state in human body. Also, the skin and genital infections by fungi can lead to toxic systemic infections and are accompanied by flushing, rashes, burning or painful sensation. The influences of licorice varieties on fungi and bacteria might be an evidence to prove the outstanding effect of newly developed licorice variety. In this study, the antifungal and antibacterial activity was investigated using newly developed licorice varieties Wongam, and Sinwongam against various fungi and bacteria. These results means newly developed licorice could be used as a replacement of already-registered species in terms of antifungal and antibacterial application.

Many probiotic species have been used as a fermentation starter for manufacturing functional food materials. We have isolated Bifidobacterium animalis subsp. lactis LDTM 8102 from the feces of infants as a novel strain for fermentation. While Glycine max has been known to display various bioactivities including anti-oxidant, anti-skin aging, and anti-cancer effects, the immune-modulatory effect of Glycine max has not been reported. In the current study, we have discovered that the extract of Glycine max fermented with B. animalis subsp. lactis LDTM 8102 (GFB 8102), could exert immuno-modulatory properties. GFB 8102 treatment increased the production of immune-stimulatory cytokines in RAW264.7 macrophages without any noticeable cytotoxicity. Analysis of the molecular mechanism revealed that GFB 8102 could upregulate MAPK2K and MAPK signaling pathways including ERK, p38, and JNK. GFB 8102 also increased the proliferation rate of splenocytes isolated from mice. In an animal study, administration of GFB 8102 partially recovered cyclophosphamide-mediated reduction in thymus and spleen weight. Moreover, splenocytes from the GFB 8102-treated group exhibited increased TNF-α, IL-6, and IL-1β production. Based on these findings, GFB 8102 could be a promising functional food material for enhancing immune function.
