In this study, the antioxidant and anti-wrinkling effects of extracts from Aruncus diocius var. kamtschaticus (ADV) were investigated. According to the results, the ethanol extract has better antioxidant and anti-wrinkling effects than the water extract. The amounts of total polyphenol and flavonoid compounds in the ethanol extract were 122 and 36 mg/g, respectively, while those in the water extract were 87 and 26 mg/g. The antioxidant activities of the ethanol and water extracts were 395 and 4,682 ${\mu}g/mL$ as the $RC_{50}$ values for the DPPH radical scavenging activity, and 227 and 366 ${\mu}g/mL$ for the $ABTS^+$ radical scavenging activity, respectively. The reducing power of the ethanol extract (1.58 at 2 mg/mL) was higher than that of the water extract (0.88 at 2 mg/mL). The astringent activities of the ethanol and water extracts were 91.27 and 16.35% at 10 mg/mL, respectively. Furthermore, the ADV ethanol extract treatment of the fibroblast cell after UV irradiation resulted in increased cell viability (10% at 100 ${\mu}g/mL$) and collagen biosynthesis (33% at 100 ${\mu}g/mL$), with a lowering in the MMP-1 expression level (16.8 % at 100 ${\mu}g/mL$). These results demonstrate that AVD provides a remarkable and significant tensor and anti-wrinkling effect on the skin, which could be of a great use in anti-aging skin care products.

This paper described the extraction/purification of $\beta$-carotene from recombinant E.coli and evaluation of anti-wrinkle activity of purified $\beta$-carotene. No significant differences in extraction yields were observed when hexane or isobutyl acetate was used. However, extraction from wet-cell cake resulted in 2-fold higher amount of $\beta$-carotene than that from dry cells. Disruption of 5 g-wet cells by ultrasonic homogenizer, acetone dehydration, extraction with isobutyl acetate resulted in 36 mg of $\beta$-carotene corresponding to 61.2% of recovery. The formation and separation of $\beta$-carotene crystal improved the purity. 633 mg of $\beta$-carotene crystal with 93% purity was obtained from 223 g/L of wet-cell cake harvested from 2.5-L fed-batch culture broth. The cultures of normal human primary fibroblast were performed to investigate the effect of $\beta$-carotene on cytotoxicity as MTT assay and anti-wrinkle activity as collagen synthesis assays. $1.7{\mu}M$ of $\beta$-carotene was found to be optimal concentration at which 1.4-fold higher amount of collagen was synthesized than that in absence of $\beta$-carotene. This indicates that highly purified $\beta$-carotene can be obtained from recombinant E.coli by applying simple method with less toxic solvent and can be used in functional cosmetics as anti-wrinkle agent.

In the present study, mycosporine-like amino acids (MAAs)were extracted from in Chlamydomonas hedleyi, and their function was investigated regarding to protective capacity against UV radiation and a possibility to be developed into functional suncream including MAAs by using natural compounds. In particulr, we assessed UV protective ability and anti-inflammation of shinorine in human skin cells. As a result, shinorine can protect the skin against damage by the absorption of energy from UV radiation and functions as an anti-wrinkling substrate through a increase of collagen synthesis. These data suggest that shinorine can be utilized not only as a substrate to protect UV radiation, but anti-aging material in cosmetic products.

5,4'-dihydroxystilbene-3-O-${\beta}$-D-glucopyranoside (Polydatin) is one of the stilbenes found in Polygonum cuspidatum (P. cuspidatum), however, the effects of polydatin on skin biology remain to be elucidated. In this study, we obtained polydatin from P. cuspidatum and investigated the effects of polydatin in skin-derived melanocytes and fibroblasts. In melanocytes, polydatin inhibited not only the tyrosinase activity and melanin production but the expression of melanogenic factors, tyrosinase and microphthalmia-associated transcription factor (MITF). In addition, the level of type I procollagen in fibroblasts was analyzed, and polydatin significantly induced the production of type I procollagen in a dose-dependent manner. Finally we conformed that topical treatment of polydatin improved wrinkle and induced whitening of human skin in vivo. These data provide evidence that polydatin can be a potent candidate for the improvement of both skin wrinkle and whitening from the point of industry view.

Background : The white jelly mushroom (Tremella fuciformis), one of the most popular edible fungi, has medicinal properties. However, the effects of T. fuciformis in skin whitening or anti-wrinkle efficacy has not been defined to date. The aim of the present study was to investigate the effects of T. fuciformis extracts on whitening and anti-wrinkle efficacy in skin cells. Methods and Results :We prepared T. fuciformis extracts with water. The extracts ($80^{\circ}C$) contained 12.11 mg/g polyphenol and 8.54 mg/g flavonoid concentration. T. fuciformis extracts markedly decreased melanin contents and tyrosinase activity in ${\alpha}$-MSH-stimulated melanocytes (B16F10 cells). In addition, the mRNA expression of melanin formation factors, such as microphthalmia-associated transcription factor (MITF), tyrosinase-related protein-1 (TRP-1) and tyrosinase-related protein-2 (TRP-2) were significantly down-regulated in ${\alpha}$-MSH-stimulated melanocyte. Furthermore, T. fuciformis extracts increased the synthesis of type I procollagen and reduced mRNA expression of matrix metalloproteinase 1 (MMP-1) in the human dermal fibroblast (HDFn cells). These data indicated that T. fuciformis extracts induce repression of cellular melanogenesis and protect against wrinkles caused by UVB-stimulated damage. Conclusions : Thus T. fuciformis extracts could be a cosmetic candidate for skin whitening and anti-wrinkle effects.

The most important object of periodontal treatment is the perfect regeneration of destructed periodontal tissue. The healing of periodontal lesion is affected by several cells & factors, which result in formation of long juntional epithelium, root resorption, bony ankylosis or connective tissue attachment. And ideal healing is enhanced by epithilial exclusion or periodontal ligament cell activation. In this investigation, I studied the effect of Zizyphus Fructus extract which enhances biologic activity& collagen synthesis, on the chemotaxis & cell nature. The cells were obtained from interdental area & middle third area of the freshly extracted teeth for the orthodontic purpose. And they were fully incubated in${\alpha}-MEM$ solution containing $100{\mu]g/ml$ penicillin & $100{\mu]g/ml$ streptomycin followed by 6 generation incubation. The test cells were collected by trypsin-EDTA & centrifuge in the fully incubated cells, counted by Hernacyotmeter, incbated $5{\times}10^5/ml$ cells for 24 hours, re-incubated 24 hours in media containing natural extract and photographed. The cells were incubated for 4 hours in 48 well microchemotaxis chamber bisecting upper & lower chamber by 8ug/m pore polycarbonate membrane coating 5mg/ml gelatin solution. The migrated cells in microscope were counted, which meaned cell chemotaxis activity. The study had shown that the morphology of cell was spindle-shaped as the control group, and the subextract test groups were not significantly different. In gingival fibroblasts, the chemotaxis effect of PDGF was statistically significant compared to control group. The Zizyphus Fructus extract was more or less enhanced chemotaxis effect and in $1{\mu}g/ml$ concentration the chemotaxis effect was slightly elevated compared with $10{\mu}g/ml$ concentration. But, among the subextracts, it was not significantly defferent. In PDL cells, the chemotaxis effect of PDGF in statistically significant, and the zizyphus Fructus extract had shown the enhanced effect. The effect was slightly higher in $1{\mu}g/ml$ concentration than 10g/ml concentration,and no significance among the subextracts.

As a novel anti-wrinkle agent, 3,9-diferuloyl-6-oxopterocarpen (Tensolin-F$^{(R)}$) has been synthesized and its anti-aging effects have been investigated. In the present study, to investigate the relationship between aging and Tensolin-F$^{(R)}$, we examined its effect on scavenging activities of radicals and reactive oxygen species (ROS), in vitro inhibition activity of matrix-metalloproteinase (MMP) and expression of UVA-induced MMPs in human dermal fibroblasts (HDF). Tensolin-F$^{(R)}$ was found to show activities of scavenging radicals and ROS with the $IC_{50}$/ values of 0.2 mM and 0.95 mM against 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical and superoxide radicals, respectively, in the xanthine/xanthine oxidase system. Fluorometric assays for the proteolytic activities of MMP-l (collagenase) were performed using fluorescent collagen substrates. Tensolin-F$^{(R)}$ inhibited the activities of MMP-l in a dose-dependent manner and the $IC_{50}$/ values calculated from semi-log plots were 0.025 mM. Also, UVA induced MMP-1 expression was reduced 85％ by treatment with Tensolin-F$^{(R)}$ at 0.8 uM, which was reduced dose-dependent manner. The results of clinical study showed that 4.8 mM Tensolin-F$^{(R)}$ treated group reduced wrinkle significantly compared with placebo treated group (P 〈 0.05). Taken together, these result suggest that Tensolin-F$^{(R)}$ act as an anti-wrinkle agent by taking effects to antioxidation and reducing UVA-induced MMP-l production.-l production.

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.

In this study, extracts from the Green ball apple peel (GBE) and the newly bred green ball apple from Korea showed inhibition effects on photo-aging factor regulation associated with skin aging. To investigate the inhibition effect on photo-aging factor regulation in skin, GBE was treated with UVB to induce photo-aging related factors in CCD986sk fibroblast cells. Photo-aging factor regulation effects showed that GBE inhibited UVB-stimulated matrix metalloproteinase (MMP)-1 and MMP-9 protein synthesis in collagen type I alpha 2 chain (COL1A2), MMP-1, MMP-9, and tissue inhibitors of metalloproteinase (TIMP)-1 protein expression. The expression of COL1A2 and TIMP-1 protein was significantly increased. The mRNA expression levels of COL1A2, MMP-1, MMP-9, hyaluronan synthase (HAS)2, transforming growth factor (TGF)-β, and TIMP-1 were decreased by GBE. The expression of TIMP-1 and TGF-β, which are regulators involved in matrix metalloproteinase and type I procollagen expression, was found to increase with increasing expression of COL1A2. The expression of HAS2, which is involved in the production of hyaluronic acid, one of the structural proteins constituting the skin, was also confirmed. Therefore, GBE showed excellent efficacy against photo-aging factor regulation and could be used as functional material to prevent and treat skin aging.
