Extracts from 63 kinds of Pholiota sp. fruiting bodies were prepared using water and methanol, and then their physiological functionalities were investigated. The methanol extracts from Pholiota adiposa PAD030 showed high fibrinolytic activity and those of P. adiposa ASI PAD-022 showed potential inhibitory activity of 76.8% against ${\beta}-hydroxy-{\beta}-methylglutaryl(HMG)-CoA$ reductase. The highest antioxidant and tyrosinase inhibitory activities were found in the water extracts of Pholiota sp. PSP-015 (72.7%) and methanol extracts of P. nameko PNA-024 (69.5%), respectively. However, superoxide dismutase(SOD)-like activity and elastase inhibitory activity were low in almost of the extracts. The HMG-CoA reductase inhibitor from the fruiting body of P. adiposa PAD-022 which showed the highest functionality was extracted maximally when powder of the fruiting body was shaked at $30^{\circ}C$ for 12 h by methanol and its HMG-CoA reductase inhibitory activity was 80.2%.

One of the important functions of skin is protection from harmful environments. Many studies have explored how to prevent skin from wrinkling and the occurrence of pigmentation changes. Skin wrinkling and pigmentation changes could be caused by unusual disruption of connective tissue, the formation of free radicals and ultraviolet radiation. In this study, extracts obtained from 254 different kinds of Jeju medicinal plants were screened for inhibitory effects on tyrosinase and elastase, and for free radical scavenging effects. Four herbs, Phormium tenax, Morus bombycis, Morus alba, and Cudrania tricuspidata, were potent inhibitors of tyrosinase ($IC_{50}$ values 4.62, 5.46, 8.17, and 64.17 ${\mu}g$/mL, respectively). Aleurites fordii [$IC_{50}$: 5.29 ${\mu}g$/mL, 1,1-diphenyl-2-picrylhydrazyl (DPPH)], Distylium racemosum ($IC_{50}$: 6.14 ${\mu}g$/mL), Acer palmatum ($IC_{50}$: 5.44 ${\mu}g$/mL), and Spiraea salicifolia ($IC_{50}$: 5.25 ${\mu}g$/mL) showed good antioxidative effects. Furthermore, Distylium racemosum ($IC_{50}$: 7.51 ${\mu}g$/mL), Diospyros kaki ($IC_{50}$: 15.1 ${\mu}g$/mL), Cornus macrophylla ($IC_{50}:$ 16.59 ${\mu}g$/mL), and Psidium guajava ($IC_{50}$: 40.25 ${\mu}g$/mL) exhibited potent inhibitory effects on elastase. These results suggest that medicinal plants possessing several biological activities may be potent inhibitors of the processes involved in pigmentation increases and aging. Further investigations will focus on in vivo assays and on the chemical identification of the major active components responsible for whitening and anti-aging activity in the screened efficacious extracts.

In this study, we evaluated the anti-oxidative, whitening and anti-wrinkle effect of Tetrapanax papyriferum extract. Tetrapanax papyriferum was extracted by two different solvents which were n-Hexane, ethyl acetate. The anti-oxidant activity was measured by free radical scavenging activity using DPPH (1,1-diphenyl-2-picrylhydrazyl radical). And the inhibitory activities of tyrosinase for whitening effect and collagenase, elastase for anti-wrinkle were investigated. For anti-oxidant activity, ethyl acetate fraction of Tetrapanax papyriferum extract showed more significant activity than n-Hexane fraction of Tetrapanax papyriferum extract. For whitening activity, n-Hexane fraction of Tetrapanax papyriferum extract exhibited strong inhibition effects compared with reference. Therefore, Tetrapanax papyriferum extract may be useful as a new antioxidant and whitening agent.

In searching for novel agents for skin anti-aging from natural resources, we found that the extract of the fruiting bodies of Ramaria formosa (R. formosa) had significant antioxidant and human neutrophil elastase (HNE) inhibitory activities. R. formosa extract exhibited a considerable DPPH radical scavenging activity with an antioxidant content of 117.0mg/mL (ascorbic acid equivalents) at the concentration of $500{\mu}g/mL$. The capacity of R. formosa extract to scavenge peroxy radicals measured by ORAC assay also showed dose-dependent antioxidant effect with $ORAC_{Roo}$ (trolox equivalents, $1{\mu}M$) values of 0.8, 5.2, and 7.8 at the concentrations of 1, 10, and $20{\mu}g/mL$. The cellular antioxidant capacity of R. formosa extract was investigated by assaying the cellular fluorescence intensity using dichlorodihydrofluorescein (DCF). The cellular oxidative stress induced by AAPH, $Cu^{2+}$ or $H_2O_2$ in HepG2 cells was significantly attenuated by more than 30% at $20{\mu}g/mL$ of R. formosa extract. HNE activity was reduced by treatment with R. formosa extract in a dose-dependent manner, and the $ED_{50}$ value for the ethanol extract of R. formosa was $42.9{\mu}g/mL$. R. formosa extract did not exhibited antimicrobial activity against four microorganisms including Bacillus subtilis (B. subtilis), Escherichia coli (E. coli), Candida albicans (C. albicans), Aspergillus oryzae (A. oryzae). Furthermore, the extract did not affect the inflammatory cytokine production of interleukin-10 and interferon-${\gamma}$ in NK92 cells. From the above results, we found that R. formosa extract has considerable antioxidant and elastase inhibitory effects, and does not stimulate immune cells. These findings suggest that R. formosa extract may be used as a bioactive component in cosmetic composition.

In this study, antioxidative effects and inhibitory effects of Geum aleppicum Jacq. extracts on tyrosinase and elastase were investigated. The ethyl acetate fraction of G. aleppicum Jacq. extract ($4.70\;{\mu}g$/mL) showed the most prominent free radical (1,1-diphenyl-2-picrylhydrazyl, DPPH) scavenging activity (FSC50). Reactive oxygen species (ROS) scavenging activities ($OSC_{50}$) of some G. aleppicum Jacq. extracts on ROS generated in $Fe^{3+}-EDTA/H_2O_2$ system were investigated using the luminol-dependent chemiluminescence assay. The ethyl acetate fraction showed the most prominent ROS scavenging activity ($0.22 \;{\mu}g$/mL). The protective effects of extract/fraction of G. aleppicum Jacq. against the rose-bengal sensitized photohemolysis of human erythrocytes were investigated. The G. aleppicum Jacq. extracts suppressed photohemolysis in a concentration dependent manner ($1{\sim}25{\mu}g$/mL), particularly the ethyl acetate fraction exhibited the most prominent celluar protective effect (${\tau}_{50}$, 416.20 min at $10 \;{\mu}g$/mL). The inhibitory effect of G. aleppicum Jacq. extracts on tyrosinase and elastase were investigated to assess their whitening and anti-winkle efficacy. The half maximal inhibitory concentration ($IC_{50}$) of the ethyl acetate fraction on tyrosinase was $95.23\;{\mu}g$/mL. The $IC_{50}$ of 50 % ethanol extract and the ethyl acetate fraction on elastase were $6.27 \;{\mu}g$/mL and $4.31 \;{\mu}g$/mL, respectively. These results indicate that extract/fraction of G. aleppicum Jacq. can function as antioxidants in biological systems, particularly skin exposed to UV radiation by scavenging $^1O_2$ and other ROS, and protect cellular membranes against ROS. Especially the ethyl acetate fraction of G. aleppicum Jacq. extracts could be applicable to new functional cosmetics for antioxidant, antiaging.
