Objectives : The purpose of this research was physiological activities, cytotoxicity, and antibacterial activities of the Cheongyeolsodokum and its constituent herbs. Methods : Physiological activities, cytotoxicity, and antibacterial activities were examined through the Cheongyeolsodokum and its constituent herbs. Results : In the physiological activities, the electron donating ability(EDA) of the water and ethanol extracts from the Cheongyeolsodokum were over 60% and 80% at 100 ppm, respectively. The EDA of the water and ethanol extract from the Cheongyeolsodokum ingredients were gradually increased as well. Water and ethanol extracts from the Cheongyeolsodokum and its constituent herbs inhibited xanthine oxidase activity, they showed superoxide dismutase(SOD)-like activity. The Cheongyeolsodokum and its constituent herbs inhibited cancer cell growth in a dose-dependant manner. Also, the clear zones against Staphylococcus aureus and S. epidermidis were clear shown at 2.5 and 5 mg/disc. Its constituent herbs showed the clear zone against various bacteria such as Candida albicans, S. aureus, S. epidermidis, and S. mutans were shown at 0.5 and 1mg/disc. Conclusions : We observed physiological activities, cytotoxicity, and antibacterial activities of the Cheongyeolsodokum and its constituent herbs.

Objectives : In this paper, we tested the applicability of shell from Persicae semen in cosmetics through cosmeceutical activities including anti-oxidant, tyrosinase inhibition and anti-inflammatory effects. Methods : Persicae semen, 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 : In the electron donating ability test, 1,000ppm of EPS (ethanol extract of shell from Persicae semen) showed an effect of 87%. SOD-like activities showed 93% at the 10,000ppm of WPS (water extract of shell from Persicae semen). In the xanthine oxidase inhibition test, 1,000ppm of BHA showed an effect of 27%, while EPS showed an effect of 62%. We were able to get an effect of 95% from EPS at 10,000 ppm in the tyrosinase inhibition test. In the anti-inflammatory test, the EPS inhibited the generation of nitric oxide. In the case of the EPS, there were no signs of cytotoxicity against raw 264.7 and anti-inflammatory effects could be identified when the manifestation of iNOS was decreased. Conclusion : Therefore, the EPS has potential as an effective raw materials for cosmetic.

The aim of this study was to assess the cosmeceutical activies of four kinds of Korea herb medicine extracts using in cosmetics and related industries. The cosmeceutical activities of extracts were investigated by tyrosinase inhibition, astringent, anti-bacterial and MTT assay for cell viability. In the whitening effect, PA that the highest tyrosinase inhibition activity showed 56% at 10 ppm in ethanol extract. Also water and ethanol extract of RE showed 54%, 68% at 1,000 ppm, respectively, but LE and CA showed lower effect. Astringent effect of water and ethanol extract of PA appeared over 60% at 1,000ppm concentration but other extracts showed no astringent effect. In the anti-bacterial test, water and ethanol extract of PA showed no anti-bacterial effect against all microorganisms. But water and ethanol extract of RE showed anti-bacterial effect on Staphylococcus aureus, ethanol extract of showed on Staphylococcus aureus and Propionibacterium acnes, ethanol extract of CA showed on Candida albicans. The resUlt of stability test showed that the emulsion of containing PA were very stable at various temperature and sun-light test. Viscosity and pH of emulsion did not change. From the results of human patch test to assess the safety of cosmetics containing PA there was no negative reaction on skin was found.

Prunus sargentii of Rosaceae familiy, has been reported to have radical scavenging activity and anti-inflammatory effect. On these facts, this research was conducted to evaluate pharmaceutical activities of the bark extracts P. sargentii. Free radical scavenging activities of fraction (Fr) -5${\sim}$10 isolated from P. sargentii was higher than 80% respectively at 10ppm. The superoxide dismutase (SOD)-like activity of Fr-5, 9 were about 97, 84%, respectively at 1,000 ppm. Xanthine oxidase inhibitory effect of Fr-9, 10 were about 75, 78%, respectively at 1,000 ppm. The tyrosinase inhibitory effect related to skin-whitening was 72, 68% in Fr-2, 9 isolated from Prunus sargentii R. at 1,000 ppm. Hyaluronidase inhibition activity related to the anti-inflammation effect was 98% for Fr-8 at 500 ppm. Isolation of the methanol soluble fraction from P. sargentii yielded two major phenol compounds, (-)-epicatechin and taxifolin. The structure of the compound was certainly determined by chemical analyses, as well as NMR and Mass spectroscopy. The present study was carried out in a search for new cosmetic material from the bark from P. sargentii. and, (-)-epicatechin and taxifolin were isolated as active principles. So P. sargentii R. methanolic extracts may be used for the cosmetic material.
