Objectives : This study aimed to establish cosmeceutical activities of Perilla frutescens var. acuta. Methods : Folium Perillae, which had been extracted, concentrated, and freeze drying with water and ethanol, have been used for the experiment. The effects on electronic donating ability, SOD-like activity, xanthine oxidase inhibition, whitening effect have been investigated in the cosmeceutical activity measurement of function experiment. Results : Both water and ethanol extracts of Perilla frutescens var. acuta showed relatively high electron donating ability of more than 70% at over 500ppm. Also, SOD like activity increased in a dose dependent matter of more than 80% at 5,000ppm, while tyrosinase showed insufficient inhibitory rate. Xanthine oxidase showed a meaningful inhibitory effect of 72.4% in water extract and 55.3% at 1,000ppm in ethanol extract. The addition of $Fe^{2+}ion\;and\;Cu^{2+}ion$ showed relatively high oxidizing inhibitory effect of 57% and 41%, respectively, at 500ppm in water extract and, when $Fe^{2+}$ ion was added in ethanol extract, the effect of 64% at 1,000ppm was achieved. Also, higher oxidizing inhibitory effect was shown against $Fe^{2+}$ rather than $Cu^{2+}$ in both water and ethanol extracts. For human cancer cells, relatively high growth inhibition ability was shown against melanoma G361 in both water and ethanol extracts. Conclusion : From the above results, it was confirmed that Perilla frutescens var. acuta could be used in functional cosmetics.

The objective of this study was to investigate the physiological activities of Cnidium officinale Makino extracts on extraction solvents. The yield of ethanol extract, 87.54%, was higher than that of the hot water extract(83.06%) and of the methanol extract(78.32%). In the inhibitory activity of xanthine oxidase, the ethanol extracts and methanol from Cnidium officinale Makino appeared to show significantly higher activity than hot water extract at $1,000{\mu}g/mL$. The DPPH radical scavenging activities of the ethanol and the methanol extracts at $50-2,000{\mu}g/mL$ were 19.96-89.01% and 19.41-88.21%, respectively. The SOD-like activities of all the extracts improved with an increase in the treatment concentration. Both collagenase and elastase inhibitory activities were shown higher from the ethanol and methanol extract compared to that of hot water extract. The tyrosinase inhibitory activity of ethanol extract, 12.04-73.85%($50-2,000{\mu}g/mL$), was higher than that of the other extracts. Taken together, these data suggest that Cnidium officinale Makino extract is effective in whitening and anti-wrinkle effect, thus it might strongly be considered as potential functional cosmetic components.

In this study, various plant extracts were screened for the effective and safe skin care ingredient according to the antioxidant activity assay guidelines. We selected an optimized combination herbal extract, Charmzone extract (CZE), which composed of Nelumbo nucifera leaves, Saururus chinensis and Orostachys japonica. CZE exerted free radical scavenging activity. It reduced reactive oxygen species formation and increased total antioxidant capacities in human keratinocyte (HaCaT) and normal human dermal fibroblasts (NHDF). CZE also leaded procollagen type 1 secretion in NHDF and decreased cellular melanin contents in B16F10. The production of nitric oxide was decreased by CZE in lipopolysaccharide-stimulated RAW264.7 in a dose dependent manner. Therefore, it is concluded that CZE can be applied for naturally derived anti-aging functional skin care ingredient for anti-oxidation, wrinkle enhancement, whitening, anti-inflammation and wound healing of skin.

The Portulaca oleracea (P. oleracea) is a popular herbal medicine in East Asia that was known to possess detoxification, antifebrile and antifungal effects. In the present study, we examined the biological activities of ethanol extracts of P. oleracea under various conditions with NIH3T3, B16F10, and MCF-7 cell line model systems. Extracts of P. oleracea (0.5 mg/ml) showed inhibition of expression of tyrosinase, but does not suppress either of TYRP-1 or DCT expression on B16F10 cells. Extracts of P. oleracea (2 mg/ml) showed anti-inflammatory effects on TNF-$\alpha$-stimulated NIH3T3/$NF{\kappa}B$-Luc cells and increase of the synthesis of collagen on NIH3T3 (wild type) cells. These results suggest that extracts of P. oleracea could be used as a functional biomaterial in developing a skin whitening agent and having the anti-inflammatory, anti-wrinkle, and anti-aging activities.

This study was to improve cosmetical activity of thiamine di-lauryl sulfate (TDS) by encapsulation of nanoparticle with lecithin. Results showed that most of the nanoparticles containing the TDS were well formed in round shape with below 150 ~ 200 nm diameter as well as they were fairly stable in various pH ranges by measuring zeta potentials. The nanoparticles of TDS resulted in 85% cell viability of human normal fibroblast cells (CCD-986sk) when added at the highest concentration (1.0 mg/mL). The nanoparticles of Acer mono sap showed highest free radical scavengering effect as 88.1% in adding sample (1.0 mg/mL), compared to TDS solution of non-encapsulation (81.6%). The nanoparticles of TDS reduced the expression of MMP-1 on UV-irradiated CCD-986sk cells down to as 41.4%. The TDS solution and nanoparticles showed significant anti-microbial activities agaionst the salmonella typhimurium and listeria monocytogenes at 5 and 6 days as compared with control. Anti-microbial activities of TDS nanoparticles were similar to positive control. These results indicated that TDS nanoparticles may be a source for functional cosmetic agents capable of improving cosmetical activity such as antioxidant, whitening, and anti-wrinkling effects and can be further developed as natural preservative in cosmetics.

Forsythia fructus has been shown to have antioxidative, anti-inflammatory, antibacterial, anti-aging and whitening effects. This work was carried out to investigate the anti-aging effects of Forsythia viridissima-prescription extracts (Yeongyoseungma-tang, Gamiyeongyoseungma-tang, Hoechunyangkyeok-san) on skin. Skin anti-aging effect of Forsythia viridissima-prescription extracts (Yeongyoseungma-tang, Gamiyeongyoseungma-tang, Hoechunyangkyeok-san) was evaluated by using antioxidant assay, anti-glycation activity, inhibitory effect of tyrosinase activity, expression of type I procollagen and UVA-induced matrix metalloproteinase-1 on HS68 cells, and reduction of ${\alpha}$-MSH-induced melanin on B16F1 cells. Forsythia viridissima-prescription extracts showed anti-oxidative and anti-glycation activity. The pectinex hydrolysed extract from Yeongyoseungma-tang 75% EtOH extract and Gamiyeongyoseungma-tang 75% EtOH extract increased the type I procollagen synthesis, and decreased the UVA-induced MMP-1 expression on HS68 cells. The pectinex hydrolysed extracts of Hoechunyangkyeok-san 75% EtOH extract had the inhibitory effect of melanin synthesis on B16F1 cells. Based on these results, we suggest that Forsythia viridissima-prescription extracts may be useful as a potential source of functional anti-aging cosmetics.

In this experiment, the Grateloupia elliptica (G. elliptica) was fermented using the fungus Aureobasidium pullulans (A. pullulans) and its extract was obtained from hot water and 70% ethanol solution. The extract was studied for their biological activities such as antioxidant effect, Collagenase and tyrosinase inhibition in comparison to the nonfermented exatract in same solvents. Antioxidative activity test using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) showed that ethanol extract had higher antioxidant activity than water extract. Among all of the samples, the antioxidant activity of G. elliptica fermented ethanol extracts (GEFEE) was highest. Tyrosinase inhibitory activity of GEFEE was highest with 9.8% at the 1,000 ㎍/mL concentration. No inhibition of collagenase from G. elliptica water extract (GEWE) and G. elliptica fermented water extract (GEFWE) was observed, but G. elliptica ethanol extracts (GEEE) and GEFEE showed increased collagenase inhibition activity with increasing concentrations of them. Collagenase inhibitory activity of GEFEE was highest with 50.3% at the 1,000 ㎍/mL concentration. MTS cell proliferation assay was conducted with the GEWE, GEEE, GEFWE, GEFEE and cell viability was over 90% at the 10 ㎍/mL ~ 1000 ㎍/mL concentrations for all of the samples, which suggested that the extracts were noncytotoxic. In conclusion, fermented extracts of G. elliptica could be developed to bioactive functional material for cosmetics with antioxidant and wrinkle improvement effects.

We recently reported the characteristics of Chrysanthemum boreale MAKINO essential oil (CBMEO) at different harvesting stages and its in vitro antioxidant, whitening, skin regeneration, and antiwrinkle properties. In the present study, we investigated the effectiveness of cosmetic creams containing 0.1% of CBMEO in terms of wrinkle reduction and safety. The participants were 22 women aged 42 to 60 y with natural wrinkles. All the participants applied the CBMEO-containing cream to the eye area for 8 weeks. Visual observations of the skin by a dermatologist were used to assess the safety of the product, and improvements in skin wrinkles (roughness) were analyzed using a skin visiometer. Neither the CBMEO-containing cream nor the placebo caused abnormal reactions, such as erythema or allergies, during the test period. The CBMEO-containing cream-exposed test regions showed a greater reduction in the roughness index as compared with those of the placebo-exposed control regions. The R1, R2, and R3 indices showed a statistically significant decrease in the test regions as compared with the placebo control regions after using the cream for 2 weeks (p<0.05). Therefore, this study demonstrated that CBMEO-containing cosmetics are safe for human use and that they have skin wrinkle improvement properties. In the future, CBMEO may be a promising product for use in the development of functional anti-wrinkle cosmetics.
