L-ascorbic acid (vitamin C) is one of the well-known antiviral agents, especially to influenza virus. Since the in vivo antiviral effect is still controversial, we investigated whether vitamin C could regulate influenza virus infection in vivo by using Gulo (-/-) mice, which cannot synthesize vitamin C like humans. First, we found that vitamin C-insufficient Gulo (-/-) mice expired within 1 week after intranasal inoculation of influenza virus (H3N2/Hongkong). Viral titers in the lung of vitamin C-insufficient Gulo (-/-) mice were definitely increased but production of anti-viral cytokine, interferon (IFN)-${\alpha}/{\beta}$, was decreased. On the contrary, the infiltration of inflammatory cells into the lung and production of pro-inflammatory cytokines, tumor necrosis factor (TNF)-${\alpha}$ and interleukin (IL)-${\alpha}/{\beta}$, were increased in the lung. Taken together, vitamin C shows in vivo antiviral immune responses at the early time of infection, especially against influenza virus, through increased production of IFN-${\alpha}/{\beta}$.

To investigate the effect of ethanol extract of Saxifraga stolonifera MEERBURGH on skin care, we measured anti-oxidant and anti-aging activity. S. stolonifera ethanol extract itself had anti-oxidant activity in a dose-dependent manner in DPPH radical scavenging. Silica dose-dependently increased the intracellular ROS generation in RAW 264.7 cells. S. stolonifera ethanol extract inhibited silica-induced intracellular superoxide anion generation, $H_2O_2$ and hydroperoxide generation in RAW 264.7 cells. S. stolonifera ethanol extract significantly inhibited both hyaluronidase and elastase activity, also significantly inhibited MMP-1(collagenase) activity as well. In NIH 3T3 fibroblast cells, S. stolonifera ethanol extract significantly increased collagen-like polymer synthesis, which suggesting the S. stolonifera ethanol extract might be used as hydration and anti-wrinkle agents. From the above results, it is suggested that the main ingredients of S. stolonifera ethanol extract play an important role in anti-oxidant and anti-aging activity.

To investigate the effect of Plantago asiatica L. Root extract on skin care, we measured anti-oxidant activity and whitening action. As a result of measuring DPPH radical scavenging activity to examine independent anti-oxidation of PRE, there was slight scavenging activity. Fluorescent materials DHE, DCF-DA and DHR were each used to measure superoxide anion, hydrogen peroxide, and hydroperoxide created in RAW 264.7 cells, all concentrations were found to dependently prevent ROS production. Tyrosinase activation was found to be blocked dose-dependant. Melanin production was also prevented dose-dependant, but the effects were slight. Therefore, it is expected to be used effectively in development of functional cosmetic materials.

The purpose of this study is verification of the anti-oxidant effect and anti-inflammatory effect of Eggplant-cheongyeolsodokum composed of 8 herbs (Solanum melongena L., Lonicera japonica Thunb., Glycyrrhiza uralensis Fisch., Ligusticum chuanxiong Hort., Angelica gigas Nakai., Coptis deltoidea C. Y. Cheng et Hsiao., Gardenia jasminoides J. Ellis., Forsythia suspensa Vahl) to confirm the possibilities as useful cosmetic material. We used the modified prescription of 'cheongyeolsodokum' contained in Korean traditional medical book 'Donguibogam' as composition of Eggplant-cheongyeolsodokum and their proportions. Eggplant-cheongyeolsodokum were extracted with hot water, 70% ethanol and then powdered. To confirm anti-oxidant effect, we investigated radical scavenging ability (DPPH, $ABTS^+$, superoxide), superoxide dismutase (SOD)-like activity, total polyphenolic contents. Also to confirm anti-inflammatory effect, we investigated inhibition effect of nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages, and Inhibition effect of the expression of inflammatory-related proteins (iNOS, COX-2) by western blot analysis. As a result, Eggplant-cheongyeolsodokum showed good anti-oxidant and anti-inflammation effects, we suggest that it can be used as an active ingredient for cosmetics.

To investigate the natural cosmetic ingredients of Benincasa hispida seed extract on skin care, we measured anti-oxidant and anti-inflammatory, and whitening effect. DPPH free radical scavenging activity was increased in a dose-dependent manner. The total phenolic content was higher in methanol extract (22.42±0.002 mgGAE/g) than water extract (9.77±0.002 mgGAE/g). MTT assay was demonstrated that the seed extract did not have a cytotoxic effect in RAW264.7 and B16F10 cell lines. We also examined to find out the inhibitory activity on NO production and secretion of TNF-α cytokine in LPS-induced RAW264.7 cells. In B16F10 melanoma cells, the seed extract significantly suppressed α-MSH induced melanin synthesis. Furthermore, westernblot analysis revealed that methanol extract dramatically downregulated the expression level of MITF, TRP-1 and TRP-2. Taken together, the B. hispida seed extract posses anti-oxidant, anti-inflammatory and skin whitening activities, which might provided its functional efficacy in cosmetic materials.
