In order to investigate the effects of Saussurea involucrata on (relationship between) aging (and Saussurea involucrata), we examined the activities of antioxidation, in vitro MMP inhibition and UVA-induced MMP-1 expression in human dermal fibroblasts. S. involucrata showed scavenging activities radicals and reactive oxygen species (ROS) with the $IC_{50}$ values of $3.89{\mu}g/mL$ against 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical and $67.29{\mu}g/mL$ against superoxide radicals in the xanthine/xanthine oxidase system, respectively. At the concentration of $1000{\mu}g/mL$, S. involucrata showed 93.27% inhibition on lipid peroxidation of linoleic acid. S. involucrata inhibited the activities of MMP-1 in a does-dependent manner and the $IC_{50}$ value calculated from semi-log plots was $97.18{\mu}g/mL$. Also, UVA induced MMP expression in human dermal fibroblasts was reduced 42.86% by treatment with S. involucrata, and MMP-1 mRNA expression was reduced in a dose-dependent manner. Therefore S. involucrata was able to significantly inhibit MMP expression in protein and mRNA level. All these results suggested that S. involucrata might act as an anti-aging agent by antioxidation and reducing UVA-induced MMP-1 production.

In order to investigate the possibility of Inonotus obliquus extract as an active ingredient for wrinkle-care cosmetics, we prepared 70 % ethanolic extract of Inonotus obliquus and measured its DPPH radical scavenging activity and elastase inhibitory activity. We also evaluated the effect of Inonotus obliquus extract on expression of MMPs and HAS-2 in fibroblast and HaCaT cell, respectively. Inonotus Obliquus extract showed DPPH radical scavenging activity and elastase inhibitory activity in a dose-dependant manner ($SC_{50}$ = 91 ${\mu}g$/mL, $IC_{50}$=124 ${\mu}g$/mL). Inonotus obliquus extract inhibited the expression of MMP-1 mRNA 50 ~ 79 % at concentrations of 5 ~ 25 ${\mu}g$/mL, and reduced the expression of MMP-2 around 20 % at a concentration of 10 ${\mu}g$/mL. And it also reduced the expression of MMP-9 54 ~ 70 % in tconcentrations of 5 to 25 ${\mu}g$/mL. Furthermore, Inonotus obliquus extract increased HAS-2 mRNA expression in a dose-dependent manner in concentrations of 5 to 25 ${\mu}g$/mL without cytotoxicity. These results suggested that Inonotus Obliquus extract could be useful as an active ingredient for wrinkle-care cosmetics.

In this study, we prepared two extracts using 1,3-butylene glycol (DBG) and ethanol (DET), with Diospyros kaki and determined the anti-oxidant, anti-aging, and whitening effects in vitro. Anti-oxidant activity was measured by DPPH and superoxide dismutase (SOD) method, and as a result, both DBG and DET extracts confirmed their anti-oxidant properties by exhibiting significant DPPH scavenging and SOD-like activities. For anti-aging activity, we measured elastase and hyaluronidase inhibition, and the inhibition of MMP-1 expression. Both DBG and DET significantly inhibited elastase and hyaluronidase activities dose-dependently, and MMP-1 expression was also reduced in both extracts. We also measured the whitening effects with tyrosinase activity and melanin production, but only DBG showed a decrease in tyrosinase. In summary, D. kaki extract has strong antioxidant, anti-aging, and whitening functions, and it is believed that it can be used as a cosmetic material in the future.

In order to investigate the possibility of Sesamum indicum L. (S. indicum) extract as an active ingredient for wrinkle-care cosmetics, we prepared 70% ethanolic extract of S. indicum and measured its elastase inhibitory activity and collagenase inhibitory activity. We also evaluated the effect of S. indicum extract on protein and mRNA expression of MMPs in fibroblast cell (CCD-986sk). For anti-wrinkle effects, elastase inhibition activities and collagenase inhibition activities were 37.8% and 45% at a dose of $1,000{\mu}g/mL$ of S. indicum 70% ethanol extract. For a cell viability test, measured on fibroblast cell by ethanol extract of S. indicum, results showed 96% with cell viability at $100{\mu}g/mL$ concentration. According to the results of western blot of ethanol extract from S. indicum the expression of the matrix metalloproteinase-1 (MMP-1), matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase-3 (MMP-3) protein was decreased by 63%, 43%, 49% at $100{\mu}g/mL$ concentration. Reverse transcription-polymerase chain reaction (PCR) of ethanol extract from S. indicum showed that the expression of MMP-1, MMP-2, MMP-3 mRNA was decreased by 82%, 79%, 82% at $100{\mu}g/mL$ concentration. The findings suggest that 70% ethanol extract from S. indicum has potential as a cosmeceutical ingredient with anti-wrinkle effects.

Three different oriental natural plants (Angelicae Dahuricae Radix, Sanguisorba Officinalis L, Euonymus alatus) were extracted with 70% methanol under refluxing for 4 hr in order to investigate their inhibitory effect on Matrix Metalloproteinase-9 (MMP-9) by a modified gelatin zymography, where only euonymus alatus showed the inhibitory effect on the activity of Matrix MMP-9. The fraction was collected by using the mixture of ethyl acetate and hexane on silica gel column. Seven portions were obtained and three fractions of them (first, third and forth) showed inhibitory effect on the zymography. To verify the effect of these substances on cells, human hepatoma, Hep3B cells as a cancer model, and Chang liver cells as a normal model were selected. In order to examine the cell viability, $1{\mu}g/mL$ of each extract was treated on cells. Most of the methanol soluble fractions showed negligible toxicity on human liver cell line.

Morinda officinalis (Rubiaceae) is a medicinal herb that has traditionally been used for the treatment of skin inflammation. The present study was to investigate the inhibitory efficacy of matrix metalloproteinases-1 (MMP-1) of the extracts of the root of M. officinalis, which was autoclaved at $132^{\circ}C$ and $1.2kgf/cm^2$ for 15 min using an autoclave. The composition of the extracts were compared with that prepared without autoclaved treatment. Total phenol and flavonoid contents were analyzed for the autoclaved M. officinalis root extract (AME) and M. officinalis root extract (ME). Results showed that the autoclaved AME contained total phenol and flavonoid contents 1.5-fold times more than those from ME. AME showed DPPH and superoxide radical scavenging activities as 79.25% and 94.5%, respectively, at the concentration of $500{\mu}g/mL$. In anti-inflammatory assay, AME inhibited the activity of COX-2 and 5-LOX metabolites. In addition, AME showed higher an inhibition rate in MMP-1 expression than ME in UVA-irradiated human dermal fibroblast (HDF) without any significant cytotoxicity. UVB-induced cytotoxicity and cell death were effectively suppressed by AME. In conclusion, autoclaving the M. officinalis root increased the phenol and flavonoid contents. The extracts of the autoclaved M. officinalis enhanced the antioxidant, anti-inflammatory and anti-MMP-1 effects. Thus, the extracts could be an useful active ingredient in cosmetics.

An anti-aging peptide was prepared from fish collagen hydrolysate (FCH) by ultrafiltration (MWCO; 1 kDa) and reversed-phased high performance liquid chromatography (RP-HPLC). Its anti-aging properties were evaluated based on the procollagen-synthesizing and MMP-1-inhibiting activities in Hs68 cells. A potent anti-aging peptide (fraction I-I) increased collagen synthesis by 46% and also inhibited MMP-1 secretion by 77%, compared with unpurified FCH. The amino acid sequence of fraction I-I was identified to be Gly-Arg-Arg-Gly-Asn-Lys (GRRGNK; the repeating Gly-X-Y sequence in collagen), and it had a molecular mass of 686.175 Da. It revealed that the anti-aging activity of GRRGNK was mainly due to skin protective effects. These results demonstrated that fish collagen hydrolysate may be a potential source of anti-aging peptides, which could be utilized in various field, including foods, cosmetics, and pharmaceuticals.

In order to develop anti-wrinkle agent, we measured the anti-oxidative activity of gallic acid (GA) from Paeonia suffruticosa Andrews and investigated its cytotoxicity in HaCaT cells and then investigated its effect on tumor necrosis factor alpha (TNF-${\alpha}$)-induced matrix metalloproteinase-1 (MMP-1) mRNA, protein expressions and secretion in same cells. GA showed anti-oxidative activity with $IC_{50}$ of 30 ${\mu}g/mL$ and its activity was higher than that of butylated hydroxyanisol (BHA). GA showed weak cytotoxicity with high concentration (200 ${\mu}g/mL$) in HaCaT cells. MMP-1 mRNA, protein expression and secretion induced by tumor necrosis factor alpha (TNF-${\alpha}$) in HaCaT cells were significantly decreased by treatment of GA with dose-dependent manner(p<0.05). Therefore, our findings suggest that GA can be useful as an active ingredient for cosmeceuticals of anti-wrinkle effects.

Several solvents were used to fractionate an extract obtained from the chapped root bark of Ulmus davidiana Planchon. The each fractionary part was condensed under reduced pressure and then examined to investigate the inhibitory effect on MMPs by modified gelatin zymography, where EA fraction showed the inhibition effect on the activity of MMPs. A compound showing inhibition effect on the MMPs was isolated and purified from EA fraction. Under IR, $^1H$- and $^{13}C$- NMR analyses it is very close to a catethin. This substance showed 48% inhibition effect on measurement of MMP-9 activity at 5 mM and 43% at 10 mM. To verify the effect of this substance on cells, human hepatoma, SK-Hep-1 cells as a cancer model, and Chang liver cells as a normal model were selected. MTT assay was performed to examine the cell viability by treatment of $1{\mu}L/mL$ of the purified substance on cells. The purified substance showed negligible toxicity on human liver cell line.

Intermediate-wavelength solar radiation, also known as ultraviolet B (UVB: 290-320 nm) radiation, may cause premature aging and oxidative damage-dependent skin cancer in humans. UVB-induced formation of reactive oxygen species (ROS)-often a consequence of excessive exposure to these rays-could activate matrix metalloproteinases (MMPs) such as MMP-1 and MMP-3. These enzymes break down type I collagen in human fibroblasts. In this study, we assessed the antioxidant and anti-aging effects of ethyl acetate extract of blueberry (EEB). An antioxidant test in blueberries evaluated ROS production using CCD-986sk cells and DPPH assay. In order to evaluate the anti-wrinkle efficacy of blueberries, the MMP-1 production and type 1 procollagen synthesis evaluated and the expression of MMP 1, 3 were tested through Western blot and RT- PCR. EEB exhibited 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity and reduced the production of UVB-induced ROS. Also, EEB inhibited UVB-induced processes associated with photoaging and skin cancer, such as reduction in procollagen production and increase in MMP-1 production. More precisely, EEB (50 ㎍/ml) markedly suppressed mRNA and protein levels of MMP-1 and -3. The anti-aging effects are attributable to the antioxidant activity of EEB. These findings indicate that EEB has a protective effect against UVB-induced aging in human fibroblast cells by regulating the levels of type-1 procollagen, MMP-1, and MMP-3.
