In this study, in an attempt to search for functional cosmetic ingredients from higher fungal, we have produced exopolysaccharides (GF-l, approximately carbohydrate 75％, protein 25％) and polysaccharide (GF-2) of mycelium extract, by submerged culture of Grifolafrondosa. For applications in anti-aging cosmetic field, we investigated the diverse biological activities. Antioxidant activity and inhibition of Matrixmetalloproteinases (MMPs) were investigated enzymatic assays by measuring the superoxide scavenging activity using xanthine-xanthine oxidase system and the proteolytic activity of MMPs using EnzChek Collagenase/Gelatinase kits, respectively. GF-l polysacchairde showed inhibition of superoxide radical by 90％ at a concentration of 0.2％ (w/v) and inhibition of collagenase by 45％ at 0.2％ (w/v). GF-2 polysaccharide of mycelium extract also exhibited good antioxidant activity. However, MMPs inhibition activity was relatively lower level compared to GF-l polysaccharides. The treatment of human dermal fibroblast (HDF) with GF-l and GF-2 polysaccharides increased the proliferation of fibroblast by approximately 23-25％ at a concentration of 0.5％ (w/v), also showed collagen synthesis increase in HDF by about 50％ at 0.5％ (w/v) compared to that of untreated control. We also report the moisturizing effects of polysaccharides in cosmetic products (O/W emulation) and its own ingredient, in vitro and in vivo. The GF-1 polysaccharide showed higher moisturizing ability than sodium hyaluronate, which is the most commonly used moisturizers ingredient. These results suggest the GF-l polysaccharide, protein-bound polysaccharide, may be used as an ingredient for new moisturizing and anti-aging cosmeceuticals.

Background: In this study, the radix of Astragalus membranaceus Bunge extract fermented by Saccharomyces cerevisiae, Weissella cibaria, and Pediococcus pentosaceus to increase the levels of isoflavonoid aglycone contents. Methods and Results: In order to change the in isoflavonoids, we fermented the radix of A. membranaceus extracts with microorganisms that have β-glucosidase activity. Besed on the β-glucosidase activity, we selected three strains, Weissella cibaria, Pediococcus pentosaceus, and Saccharomyces cerevisiae. HPLC analysis revealed that the levels of isoflavonoid aglycones were increased in all fermentation cases, and the extracts fermented by S. cerevisiae showed the highest levels of isoflavonoid aglycones. We evaluated the antioxidant activity, anti-wrinkle effects and whitening effects of the S. cerevisiae-fermented extracts using the DPPH assay, tyrosinase inhibition activity assay, and collagenase inhibition activity assay. We confirmed higher activity in S. cerevisiae-fermented extracts than in control, with the half maximal inhibitory concentration (IC₅₀) value of 565.1 ± 59.1 ㎍/㎖ in DPPH radical scavenging activity, tyrosinase inhibition rate of 78.4 ± 0.9%, and collagenase inhibition rate of 83.8 ± 1.1%. Conclusions: We selected three stains of microorganisms showing high β-glucosidase activity, W. cibaria, P. pentosaceus and S. cerevisiae. Isoflavonoid glycones in the radix of A. membranaceus were converted to isoflavonoid aglycones by fermentation. In addition, the fermented radix of A. membranaceus exhibited antioxidant activity, anti-wrinkle effect, whitening effect and radical scavenging activity.

Objective : This study was designed to investigate anti-oxidative, anti-aging and anti-inflammatory activities of Zingiber officinale Roscoe water (ZD) and 50% ethanol extracts (ZE). Method : The antioxidant capacity of ZD or ZE was analyzed by DPPH, ABTS scavenging activities and reducing power, respectively. The anti-aging efficacy was performed with tyrosinase and collagenase inhibition activities. The anti-inflammatory activities were confirmed through inhibition of nitric oxide production and TNF-�� expression in LPS-treated Raw 264.7 cells. Result : As a result of measuring DPPH and ABTS radical scavenging activities, both ZD and ZE extracts increased in concentration-dependent manners. The ABTS radical scavenging activities of water and 50% ethanol extract were similar to that of positive control at high concentration. On reducing power, both ZD and ZE showed higher activities than the positive control at high concentration. On inhibition activities of tyrosinase and collagenase both ZD and ZE showed the large inhibition rates at low concentration. Also, the inhibitory efficacy of ZD on NO and TNF-�� production was better than ZE in RAW 264.7 cells. Conclusion : These results suggest that ZD and ZE have anti-oxidative, anti-aging and anti-inflammatory effects in vitro. Especially, ZD was more effective than ZE. Thus, Ginger extract is considered to be highly useful as a cosmetic or food material with anti-oxidative, anti-aging (prevention of whitening and wrinkle) and anti-inflammatory effects. Also these effects may vary depending on the extraction solvent.

Anti-metastatic activities of IH901, an intestinal bacterial metabolic derivative formed from Ginseng protopanaxadiol saponins, was determined in vitro and in vivo. Under in vitro conditions, IH901 inhibited the migration of bovine aortic endothelial cells 25 times stronger than suramin and suppressed the invasion of HT1080 human fibrosarcoma cells into reconstituted basement membrane components of Matrigel 1000 times stronger than RGDS peptide. IH901 also showed inhibitory effect on type-IV collagenase secretion from HT 1080 cells and platelet aggregation. When the anti-metastatic activity of IH901 was evaluated in comparison with that of 5-FU using a spontaneous lung metastatic model of Lewis lung carcinoma, the administration of IH901 (10 mg/kg p. o.) to tumor-bearing mice led to a significant decrease in lung metastasis (43% of untreated control), which was slightly more effective than that obtained with 5-FU (56% of control). Thus, IH901 seems to exhibit its anti-metastatic activity partly through the inhibition of tumor invasion which results from the blockade of type IV collagenase secretion and also through anti-platelet and anti-angiogenic activities.

This study was conducted to investigate the possibility of peanut shell, a by-product of peanut, as a functional cosmetic ingredient. Peanut shell extract showed high antioxidant activity with IC₅₀ values of 75.00, 46.33, and 472.83 ㎍/mL for DPPH and ABTS radical scavenging and SOD-like activity, respectively. Furthermore, peanut shell extract was efficiently decreased the MMP-1 and MMP-3 protein level in the UVB treated-HaCaT cell and maintained procollagen protein level similar to normal control. Similar to anti-wrinkle related protein expression assay, the IC₅₀ value of elastase and collagnease inhibition in peanut shell extract was lower as 0.30 and 0.09 mg/mL, respectively, than that of the positive control. Additionally, eriodictyol and luteolin, which are isolated from peanut shell extract, showed 53.8 and 98.0% elastase inhibition rate, respectively, and 60.1 and 72.5% collagenase inhibition rate, respectively, at a concentration of 0.1 mg/mL. Thus, luteolin was assumed to be the effective ingredient for wrinkle inhibition in peanut shell extract. As a result of stability evaluation of lotion and cream formulations containing peanut shell extract, it was confirmed to be a stable formulation with no significant changes. Therefore, it is considered that peanut shell extract can be applied as a cosmetic ingredient for wrinkle inhibition.

The purpose of the present research was to investigate the physiological activities of the thermal treated eggplant on the skin. Five minute of thermal treatment at $100^{\circ}C$ had the highest polyphenol content of eggplant. However, below and over 5 min of thermal treatment time, they did not increase. When water and ethanol extracts were used, the maximum DPPH radical scavenging activities were obtained, 66.3 and 62.8%, respectively. Among various extracts, the acetone extract gave the highest cosmetic activity. Especially, when acetone extract (15.0 mg/mL) was used, the maximum inhibition activities of tyrosinase, elastase, and collagenase were obtained, 83.4, 78.2 and 62.5%, respectively. These results suggest the anti-wrinkle and whitening and effects of acetone extract were excellent. Therefore, it is should be considered as a promising candidate for novel cosmetic agents.

In this study, we investigated anti-oxidative effects of Duchesnea indica extracts by using Oxygen Radical Absorbance Capacity (ORAC). The extracts were prepared with 0 %, 30 %, 50 %, 70 % and 100 % aqueous ethanol respectively. The 30 % EtOH D. indica extract showed higher ORAC activity than the other extracts. Therefore, we performed in vitro studies on cytotoxicity of NIH-3T3 cells and MMP-8 collagenase inhibition using by the 30 % EtOH extract. The 30 % EtOH extract showed no cytotoxicity and significant inhibition on MMP-8 collagenase. And we performed clinical studies for the anti-wrinkle effect of the Di-Wrinkle Free Cream. The cream formula was prepared with 2 % arbutin and 1 % D. indica extract. Twenty one healthy women volunteers, ages of 35 and 50, applied the cream on their faces twice a day for 8 weeks. The skin was evaluated with PRIMOS (phaseshift rapid in vivo measuring of human skin) system and analyzed by the student's paired t-test. The wrinkles on the eye region were reduced by 13 % based on the PRIMOS system after 8 weeks. In the safety study of the Di-Wrinkle Free Cream, no symptoms were observed such as erythema, edema, scaling, itching, stinging, burning, tightness and prickling by visual observation and medical examination of volunteers for 8 weeks. Moreover, there was no noticeable skin disorder during experience period. These results suggested that D. indica extracts could be applied as cosmeceuticals effective for anti-wrinkle.

This study analyzed the in vitro physiological activity of Aconitum pseudolaeve var erectum Nakai (AP) and its effect on perfume on an electroencephalogram (EEG). The results indicated that the absolute alpha power spectrum (AA) and the absolute theta power spectrum (AT) decreased significantly during more than before the inhalation of the AP perfume and its reconstruction perfume. Although there were a little different pattern in the induced part of the wave generated by the inhalation of the AP perfume and its reconstruction perfume, alpha- and theta- were shown equally. In addition, there was the same pattern in which the rate of increase reduced. The results suggest that the perfume of the AP and its reconstruction perfume have a stimulating effect on the brain. In terms of the physiological activity of AP, the activity of AP ethanol extract was significantly higher than that of water extract in DPPH, collagenase, and nitric oxide, except for an astringent effect. The AP ethanol extract was about 80% at 500 ppm in collagenase inhibition activity. In addition, the AP water and ethanol extracts were 50% at 100 ppm in the NO inhibition activity. Based on these results, we conclude that this natural substance could be used in cosmetics and in the development of perfumes.

This study investigates the effect of Salicornia bigelovii extract on the activities of antioxidant, anti-wrinkle and whitening. Among amino acids, the glutamic acid concentration was the highest with an order of proline > alanine > $\gamma$-amino-n-butyric acid > arginine. The total polyphenol concentration and antioxidant activity were an order of ethyl acetate extract > n-butanol extract > hexane extract > hot water extract > ethanol extract. Especially, when ethylacetate was used as extractant, the total polyphenol concentration and antioxidant activity were 31.6 mg/mL and 82.6%, respectively. The inhibition activity of tyrosinase was increased with the increase concentration of ethylacetate extract. Especially, when the extract concentration was increased from 20 to 100 mg/mL, it was raised from 15.2 to 98.2%. In the case of inhibition activities of elastase, and collagenase, they were also increased with the increase concentration of ethylacetate extract. When the extract concentrations were increased from 20 to 100 ug/mL, they were enhanced from 2.9 to 32.5% and from 3.8 to 29.7%, respectively. The results show that the ethyl acetate extract of Salicornia bigelovii can be applied as sources for functional cosmetics and pharmaceuticals.
