The contents of phenolic compounds in water and 40% ethanol extracts from Okkwang (Castanea crenata) chestnut bur solid (OCS) were $11.24{\mu}g/50{\mu}g$ solid and $10.28{\mu}g/50{\mu}g$ solid, respectively. The 1,1-diphenyl-2-picrylhydrazyl free radical scavenging and 2,2'-azino-bis(3-ethylbenzothiazoline- 6-sulfonic acid) radical decolorization activities of water and ethanol extracts were 85% and 100% as well as 87% and 86% at a solid content of $50{\mu}g/mL$, respectively. The anti-oxidant protection factors (PFs) of water and ethanol extracts at a solid content of $200{\mu}g/mL$ were 1.22 PF and 1.45 PF, respectively. Thiobarbituric acid reactive substance were 83% in water extract and 73% in ethanol extract at a solid content of $200{\mu}g/mL$. The inhibitory activities against xanthine oxidase in water and ethanol extracts were 54% and 43% at a solid content of $200{\mu}g/mL$, respectively. The inhibitory activities against ${\alpha}$-glucosidase were 95% in water extract and 96% in ethanol extract at a solid content of $50{\mu}g/mL$. Tyrosinase inhibitory activity was 27% in ethanol extract at a solid content of $200{\mu}g/mL$. The collagenase and elastase inhibitory activities as anti-wrinkle effect were 93% and 11% in water extract as well as 94% and 56% in ethanol extract at a solid content of $200{\mu}g/mL$. Hyaluronidase inhibitory activity as anti-inflammatory effect of water and ethanol extracts were 96% and 52% at a solid content of $200{\mu}g/mL$, respectively. The results show that extracts from OCS can be used as a functional resource with antioxidant, anti-gout, carbohydrate degradation inhibitory, whitening, anti-wrinkle, and anti-inflammatory activities.

In this study, the antioxidative effects, inhibitory effects on tyrosinase, elastase of Persicaria perfoliata extracts were investigated. The deglycosylated fraction of extract ($12.38{\mu}g$/mL) showed the most prominent free radical (1,1-diphenyl-2-picrylhydrazyl, DPPH) scavenging activity ($FSC_{50}$). Reactive oxygen species (ROS) scavenging activities ($OSC_{50}$) of P. perfoliata extracts on ROS generated in $Fe^{3+}$-EDTA/$H_2O_2$ system were investigated using the luminol-dependent chemiluminescence assay. The ethyl acetate fraction of extract ($0.35{\mu}g$/mL) showed the most prominent ROS scavenging activity. The protective effects of P. perfoliata extract/fractions on the rose-bengal sensitized photohemolysis of human erythrocytes were investigated. The P. perfoliata extracts suppressed photohemolysis in a concentration dependent manner ($1{\sim}50{\mu}g$/mL) except the deglycosylated fraction of extract. The inhibitory effect of P. perfoliata extracts on tyrosinase was investigated to assess their whitening efficacy. Inhibitory effects ($IC_{50}$) on tyrosinase were determined with ethyl acetate fraction of P. perfoliata extract ($136.00{\mu}g$/mL) and deglycosylated fraction of extract ($68.10{\mu}g$/mL). Finally, their anti-elastase activities were measured to predict the anti-wrinkle efficacy in the human skin. Inhibitory effects ($IC_{50}$) on elastase were determined with ethyl acetate fraction of P. perfoliata extract ($67.20{\mu}g$/mL) and deglycosylated fraction of extract ($43.50{\mu}g$/mL). These results indicate that extract/fractions of P. perfoliata 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. Extract/fractions of P. perfoliata can be applicable to new functional cosmetics for antioxidant, antiaging.

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.

It got the purified oil through evaporating them at $55^{\circ}C$ during under vacuum. As the results, appearance was slightly brown, gravity=0.922 acid value=0.12, saponification value=192, and it should be obtained the $40{\pm}5%$ of yield. As the efficacy evalution of cosmetic field, the antioxidative activities by NBT method were stronger 86.0% from extract of talus seeds than 52.0% from green tea extract and 35.0% from skullcap extract as well as the antioxidative activities by DPPH method were stronger 93.7% from extract of seed than 60.3% from extract of green tea and 27.1% from extract of skullcap. These are more effective than other plant extracts. The collagen synthesis rate on the activating fibroblast for Taxus cuspidata Sibe extract showed 35.43%. As the activity of the skin elasticity, PPE(porcine pancreatic elastase)-inhibitory activities of talus extract was 50.8%. Anti-inflammatory activity was more effective to be taken 41.1% of taxus seed oil than 24.2% of steady glycyrrhetinate (SG) as a control.
The content phenolic compounds in extracts from Rehmannia glutinosa was the highest in 40% ethanol extracts as $5.1{\pm}0.2mg/g$. DPPH scavenging activity of R. glutinosa extracts was high in water extracts and 40% ethanol extracts as 85~93%, ABTS radical cation decolorization of water extracts and 40% ethanol extracts was about the same as 55~62%, antioxidant protection factor (PF) was confirmed in water extracts and 40% ethanol extracts as 1.6~1.9 PF, and TBARs of water extracts and 40% ethanol extracts were concluded to have the similar antioxidant effects. The hypertension inhibitory activity of water extracts and 40% ethanol extracts from R. glutinosa indicated the activities as 87.2% and 81.1%, anti-gout activity was determined very low in R. glutinosa extracts and antimicrobial activity against skin microorgasm was confirmed, and tyrosinase inhibitory activity was determined as 70.2% in 40% ethanol extracts, it was expected the whitening effects in 40% ethanol extracts. The elastase inhibitory activity which are related to the wrinkle cause was observed in water extracts and 40% ethanol extracts as 76.2% and 57.2%. The hyaluronidase inhibitory activity to R. glutinosa extracts was observed weakly in only 40% ethanol extracts of $200{\mu}g/ml$ phenolic content as 5.1%.

The purpose of this study is to develop bathing aids as a strategic products to promote the medical tourism in Sancheong Jirisan Oriental medicinal herbs special district using medicinal herbs produced in Sancheong province, and to verify the effect of the bathing aids in vitro. We investigated the cytotoxicity activity, antioxidant activity, antiaging and whitening effects of Sanchung-PNU 1 (SP1) and Sanchung-PNU 2 (SP2) made with traditional medicinal herbs. The cytotoxicity activity was measured by MTT (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide) assay. Antioxidant activities were determined by DPPH (1.1-diphenyl-2-picrylhydrazyl) radical scavenging capacity assay. We measured the inhibitory effect against tyrosinase activity to prove the whitening effect, and the inhibitory effect against elastase activity to prove the anti-aging effect. Two proposed prescriptions, SP1 and SP2, showed not significant cytotoxicity but significant (p<0.001) improvement in anti-oxidation, anti-wrinkle, and whitening effects compared to the control group. The result shows that these bathing aids have excellent DPPH radical scavenging effect and significant inhibitory effect against elastase and tyrosinase activity. These findings suggest that these bathing aids have a strong antioxidant, anti-aging, and whitening effect.
The in-vitro whitening and anti-wrinkle effect of ethanol extracts from apple flesh and peel were investigated. The EtOAc fractions from the ethanol extracts of apple flesh and peel showed in-vitro antioxidant activities in a dose-dependent manner on ABTS radical-scavenging activity and ferric-reducing/antioxidant power, and had the highest total phenolic contents (84.25 and 318.25 mg GAE/g). In addition, the EtOAc fractions generally showed strong UV absorption within the UV-B range. In the cellular system, the melanin synthesis of the B16/F10 melanoma cells was decreased by the EtOAc fractions of apple peel in a concentration-dependent manner. The EtOAc fractions of apple peel also showed a great elastase inhibition of 46.40% at 100 ${\mu}g$/mL, thus showing good in-vitro anti-wrinkle characteristics. These results suggest that the EtOAc fractions from the ethanol extract of apple peel can be used as whitening and anti-wrinkle agents as well as antioxidant resources.
Objectives: The present study is to observe the skin-regeneration, anti-wrinkle, whitening and skin moisturizing effects of Cheongsangbangpung-tang (CSBPT) with cytotoxicity. Methods: In the present study, cytotoxicity of CSBPT lyophilized aqueous extracts (yield=18.71%) was experimented against human normal fibroblast cells and B16F10 murine melanoma cells by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium Bromide (MTT) assay, and skin regeneration and anti-wrinkle effects were also showed through the assay of collagen type I synthesis by an enzyme immunoassay (EIA) kit as comparing with transforming growth factor (TGF)-${\beta}1$, hyaluronidase, collagenase and matrix metalloproteinase (MMP)-1 inhibitory assays as comparing with oleanolic acid (OA), and elastase inhibitory effects as comparing with phosphoramidon disodium salt (PP). In addition, whitening effects of CSBPT were observed by tyrosinase inhibitory assay and melanin formation test in B16/F10 melanoma cells as comparing with arbutin, and skin moisturizing effects were measured through mouse skin water contents test, respectively. Results: No CSBPT treatment related cytotoxic effects were demonstrated against human normal fibroblast cells and B16/F10 murine melanoma cells. CSBPT concentration-dependent increased collagen type I synthesis at human normal fibroblast cells. It also effectively suspreessed hyaluronidase, collagenase, elastase and MMP-1 activities, which were enzymes that related to declining of ECM and formation of wrinkle. CSBPT supressed B16/F10 melanoma cells's melanin productions with tyrosinase activity, which was an enzyme connected with melanin formation, and dose-dependent and significant increases of skin water contents were detected in CSBPT treated mouse skin as compared with vehicle control skins. Conclusions: CSBPT showed favorable and enough skin regeneration, anti-wrinkle, whitening and skin moisturizing effects at least in a condition of this experiment. However, more detail mechanism and in vivo skin protective efficacy studies should be conducted in future with the screening of the biological active compounds in individual herbs of Cheongsangbangpung-tang.
