Several biological activities of Rhododendron mucronulatum were investigated. The electron donating abilities of ethanol extracts of Rhododendron mucronulatum were more than 90% at 100 ppm, 500 ppm and 1,000 ppm. Xanthine oxidase was inhibition about 46% by the ethanol extracts of R. mucronulatum at 500 ppm 48% of tyrosinase activity relating to skin-whitening was shown at 1,000 ppm. Uniquely, the anti-microbial effects of water extract and ethanol extract were shown only on Staphylococcus aureus. The water extract 1 mg/disc showed the higher activity than ethanol extract. The growth inhibition effect of each sample on lung cancer (A549) and melanoma (B16F10) cell lines were over 70% at 1,000 ppm, while the effects on the melanoma (G361) and liver cancer (HepG2) were about 50% at the same concentration.

Objectives : The purpose of this research was physiological activities and investigate cytotoxicity of Sunbanghwalmyung-um extract. Methods : Physiological activity and a cytotoxicity were examined through the hot water and ethanol extracts from Sunbanghwalmyung-um and its ingredient. Results : The electron donating ability(EDA) was 66.9%, 71.3% in 1000 ppm water extract and ethanol extract. Above 90% from 1000 ppm ethanol extract showed a higher activities and it is Rhei Radix et Rhizoma, Lonicerae Flos, Gleditsiae Spina, Glycyrrhizae Radix, Myrrh. SOD-like activity was weak as 12.24%, 16.62% in 700 ppm. In water and ethanol extracts cytotoxicity were against G361, B16F10, MDA, A549, high cytotoxity over 70%. Rhei Radix et Rhizoma, Gleditsiae Spina, Trichosanthis Radix, Paeoniae Radix Rubra showed high cytotoxicity in water and ethanol extracts. Conclusions : We observed physiological activities and investigated cytotoxicity of Sunbanghwalmyung-um and its ingredients. The results also demonstrated in food or cosmetic industry.

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.

This study was carried out to investigate the cosmeceutical activities of Persicae semen. Cosmeceutical activities include anti-oxidant, tyrosinase inhibition effects and nitrite scavenging ability. The Persicae semen was divided into three parts, Bean of Persicae semen (BPS), Shell of Persicae semen (SPS) and Nibs of Persicae semen (NPS). In the electron donating ability test, 1,000ppm of water extract from BPS showed an effect of 89%, while 1,000 ppm of ethanol extract from SPS showed an effect of 87%. These results are higher compared to those of BHA at the equal concentration. We were able to get an effect of 98% from all of Persicae semen ethanol extract of 10,000 ppm in the tyrosinase inhibition test. Nitrite scavenging ability test, ethanol extract from BPS was decreasing to 96% by addition of 1,000ppm. According to these results, we find that Persicae semen applicable to advanced material for cosmetics. From the above results, it was confirmed that Persicae semen could be used in functional cosmetics.
