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.

In this study, the efficacy of antioxidant and whitening factors was analyzed in order to verify the possibility of use as functional cosmetic materials related to antioxidant and whitening by using the extract of Oryza sativa cv. Heugjinmi. As a result, S OD-like activity, FRAP, reducing power, xanthine oxidase inhibitory activity, and elastase inhibitory activity were similar to those of the control group. Tyrosinase inhibitory activity had no effect in hydrothermal extract and 59% inhibitory activity in ethanol extract. Ethanol extract was found to inhibit cellular tyrosinase inhibitory activity and melanin biosynthesis at concentrations of 25, 50, and 100 ㎍/mL, which will not affect survival in the B16F10 cell line. In addition, the results of confirming the mRNA expression of tyrosinase, TRP-1, and TRP-2 showed inhibition rates of 37%, 51%, and 34%, respectively, at the highest concentration of 100 ㎍/mL. Therefore, it is believed that O. sativa extract has potential to be utilized as a functional cosmetic material related to antioxidant and whitening.

To investigate the cyclohexane and xylene mixture treatment on the liver damage, the rats were treated by the mixture of cyclohexane and xylene (CH＋X) and then, liver damage was demonstrated by liver function findings based on liver weight/body weight, serum level of alanine aminotransferase (ALT), xanthine oxidase (XO) and then compared with cyclohexane treated group (CH group) and xylene-treated group (X). The CH＋X group showed merely severer liver damge than CH or X group. On the other hand, CH＋X group showed lower activity of hepatic cytochrome P-450 dependent aniline hydroxylase (CYPdAH) than CH or X group, but no statical differences were demonstrated among three experimental groups. Especially the hepatic GSH content was merely declined than CH or X group and the activity of hepatic GST was higher in CH＋X group than CH or X group. In conclusion, cyclohexane and xylene mixture treated animals showed merely severer liver damage than cyclohexane or xylene treated group and such a fact may be caused by inhibition of cyclohexane or xylene metabolism and oxygen free radical.

In this study, we investigated the effect of Teminalia Chebula (TC) water extract on liver in Rat. Treatment of TC water extract was orally administered 200, 300 mg/kg daily for one week and two weeks. The clinical parameters of serum, values of AST, ALT showed significantly higher than in normal group. Xanthine oxidase and aldehyde oxidase activities were significantly increased comparison with normal group. Microsomal enzymes, aminopyrine N-demethylase and aniline hydroxylase were not affected. Water extract of TC also increased hepatic rnalondialdehyde formation and reduced glutathione content. We also found that water extract of TC decreased activities of glutathione S-transferase and glutathione reductase but was not affected activities of $\gamma$-glutamylcysteine synthetase Thus, it seems that the water extract of TC induced decrease of oxygen free radical scavenger, glutathione content by inhibition of glutathione reductase which may reform oxidized glutathione to reduced glutathione.

The content of phenolic compounds from Chrysanthemum incidicum Linne were the highest when extracted for 6 hr with 70% ethanol. The extraction yield of water and ethanol extracts were $7.12{\pm}1.61$ mg/g and $7.51{\pm}2.14$ mg/g, respectively. With ultrafine grinding, water and ethanol extracts were $8.63{\pm}1.15$ mg/g and $9.33{\pm}1.35$ mg/g, respectively. In determining anti-oxidative activity of Chrysanthemum incidicum Linne extracts, DPPH of normal grinding extracts was 83.52% and ultrafine grinding was 92.37%. In ABTS radical cation decolorization, normal grinding, fine grinding, and ultrafine grinding extracts were 90% or higher. In antioxidant protection factor (PF), water and ethanol extracts of ultrafine grinding showed relatively high anti-oxidative activities of each 1.82 PF and 2.16 PF, respectively. The TBARS value of ultrafine grinding extracts were lower than normal grinding and fine grinding extracts. The inhibition activity on xanthin oxidase of Chrysanthemum incidicum Linne extracts was 67.53% in ultrafine grinded water extracts and 83.45% in ultrafine grinded ethanol extracts. Inhibition on xanthin oxidase of ethanol extracts showed a higher inhibition effect than water extracts, and ultrafine grinding was higher than normal grinding. In angiotensin converting enzyme inhibition activity, ultrafine grinding water extract was 24% or higher, and ethanol extract was 34% or higher. The elastase inhibition activity of ultrafine grinding extract was 25.56%, which was higher than 20.34% of fine grinding extracts. Water extracts did not show hyaluronidase inhibition activity but ethanol extracts showed 35% of hyaluronidase inhibition activity. The determining expression inhibition of iNOS and COX-2 protein in macrophage by Chrysanthemum incidicum Linne extracts with a Western blot analysis, iNOS and COX-2 protein expression inhibition by Chrysanthemum incidicum Linne ethanol extracts were 40% and 15%, respectively at 100 ${\mu}g/mL$ concentration. The inhibitory patterns of iNOS and COX-2 protein expression was concentration dependent. The result suggests that Chrysanthemum incidicum Linne extracts by ultrafine grinding may be more useful than normal grinding as potential sources due to anti-oxidation, angiotensin converting enzyme and xanthine oxidase inhibition, anti-inflammation effect.

This study was designed to determine the biological activities of Chionanthus retusus flower extracts. Water and 90% ethanol extracts of C. retusus flower were prepared. The inhibitory activities of water and ethanol extracts with a phenolic content of $200{\mu}g/mL$ against xanthine oxidase were 25.60% and 15.92%, respectively. Further, the water extract did not show any inhibitory activity against ${\alpha}$-glucosidase whereas the ethanol extract showed 100.00% inhibition of ${\alpha}$-glucosidase. The inhibitory activities of the extracts against tyrosinase were 17.27% (water extract) and 36.13% (ethanol extract), which suggest that the extracts may have a whitening effect. The water extract did not inhibit elastase activity but showed a collagenase-inhibitory activity of 20.21%. On the contrary, the ethanol extract showed 96.26% and 35.93% inhibition of collagenase and elastase, respectively. These findings suggest that the extracts may have an anti-wrinkle effect. Lastly, the extracts showed a hyaluronidase inhibitory activity of 36.96% (water extract) and 88.70% (ethanol extract), suggesting that they may have an anti-inflammatory effect. The results indicate that C. retusus flower extracts containing phenolic compounds can be used as functional resources because they have anti-gout, carbohydrate degradation-inhibitory, whitening, anti-wrinkle, and anti-inflammatory effects.
