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. The results also indicated that water extract and ethanol extract of Cheongyeolsodokum and its constituent herbs can be used as a natural ingredient in food or cosmetic industry.

본 논문은 도인(桃仁)(Persicae semen)의 화장품 약리활성으로 항산화 효과, tyrosinase 억제효과, 아질산염 소거능를 살펴보았다. 도인(桃仁)은 도인 전체, 껍질, 껍질을 제외한 알맹이로 각각 나누어 사용하였다. 도인(桃仁) 껍질 열수 추출물과 에탄올 추출물은 1,000 ppm에서 각각 89%, 87%이상의 전자 공여능을 나타내어 같은 농도의 BHA에 비해 높은 효과를 나타내었다. SOD 유사활성실험에서 10,000 ppm의 BHA가 89%, 도인(桃仁) 껍질 열수 추출물은 93%의 효과를 나타내었다. Xanthine oxidase 억제실험에서는 1,000 ppm의 BHA가 27%의 효과를 나타내었고, 도인(桃仁) 껍질 에탄올 추출물은 62%의 효과를 나타내었다. Tyrosinase 억제실험에서 도인(桃仁) 전체, 껍질, 알맹이 에탄올 추출물 10,000 ppm에서 모두 98%이상의 효과를 나타내었다. 1,000 ppm의 도인껍질 에탄올 추출물에서 96%의 아질산염 소거능을 나타내었다. 위와 같은 결과를 통해 도인(桃仁)의 화장품 천연소재로써 응용 가능함을 알 수 있었다.

피부는 인체의 외부를 덮고 있는 기관일 뿐 아니라, 체온을 조절하고, 감각기능을 수행하며, 약물을 투입하는 경로가 되기도 하고 내부 기관의 이상을 표현하는 기관이 되기도 한다. 이러한 이유로 인해, 사람들은 타인의 얼굴 피부의 상태를 보고 건강의 이상 징후를 감지하거나, "안색이 좋다", "생기가 있다" 등으로 신체의 컨디션을 표현해왔다. 환경과 노화정도에 따라서 피부색, 피부결, 수분, 탄력 등이 달라지는 것도 알려진 사실이다. 특히, 피부색은 아름다움, 매력도와 같은 주관적인 인상을 판단하는데 영향을 미치는 인자로 작용하는데, 화장품이나 피부시술을 통해 피부색을 개선하고자 하는 소비자를 통해서 그 수요를 짐작할 수 있다. 하지만 피부색이 여러 색의 구성임에도 불구하고, 대부분의 화장품이 하얀 피부로 개선해주는 것에 초점을 맞추고 있으며 여성들이 선호하는 피부색에 대한 연구가 아직까지는 미흡한 실정이다. 본 연구에서는 30 ~ 40대의 한국여성을 대상으로 같은 피부 밝기에서 붉은 정도와 푸른 정도가 달리 주어진 선호도 조사를 통해 긍정적으로 인식하는 피부색의 상태를 발견하였다. 한국여성은 실제 평균 피부색에 비해 붉은색과 푸른색이 높은 피부를 선호하는 것으로 나타났으며, 피부에 대한 표현을 달리하였을 때에도 경향은 유사하였다. 본 연구 결과는 새로운 소비자의 요구를 만족시키는 제품 개발에 활용될 수 있을 것이라고 생각한다.

Objectives : Antioxidant, Anticancer and Antibacterial Activities of Naesohwangryntang and its composition oriental medicines. Methods : We were experimented anti-oxidation effect and growth inhibition ability on cancer cells and antibacterial activity on various kinds of bacteria of skin. Results : The results were obtained as follows : Electron donating ability(EDA) of water extract Naesohwangryntang and ethanol extract Naesohwangryntang was 60% and 70% at 1000 ppm concentration. In the test of SOD-like activity, ethanol extract showed more activity with 27.4% in 700 ppm, while water extract was low in 19.6%. Clear zones formed by sample against the human skin-resident microflora indicated that anti-microbial activity of ethanol extract Naesohwangryntang was higher than that of water extract Naesohwangryntang. The growth inhibition rates of each sample on lung-cancer(A549), at 1000 ppm cancer cell was over 40%. The growth inhibition rate of the each sample melanoma-cancer(B16F10, G361), at 1000 ppm was over 80%. Conclusions : The results indicated that, ethanol extract which is superior in its anti-oxidation and antibacterial effect is useful to be applied in cosmetic industry.

The most extensively used synthetic antioxidants are butylated hydroxyanisole (BHA), butylated hydroxy toluene (BHT) and tert-butylhydroquinone (TBHQ). However BHT and BRA have been suspented of being responsible for liver damage andcar cinogenesis. Therefore, the importance of the search and exploitation of natural antioxidant, especially of plant origin, has greatly increased in recent years. Plant contain a wide variety of chemicals that have potent biological effects. As a result, there has been a growing interest in the use of herbs as a source of therapeutic drugs. The aim of this study was to assess the antioxidant and cosmeceutical of natural materials. The antioxidant and cosmeceutical activity of natural materials were investigated by hydroxyl radical scavenging, superoxide dismutase (SOD) -like, xanthine oxidase inhibition, tyrosinase inhibition, anti-microbial and astringent.

Sopoongsan is an oriental medicinal composition including 12 medicinal herbs. Sopoongsan is known to have anti-inflammatory, antimicrobial, anti-allergic, and anticancer effects on human skin. The results of stability test showed that the creams containing Sopoongsan extracts were very stable at both accelerated temperature conditions and sun-light. And pH and viscosity of each cream did not change greatly for 56 days. From the particle size and rheological measurements, it can be known that when the amount of the Sopoongsan extracts increases, the mean value of particle size decreases, and the value of the complex modulus and loss angle increases, which means the Sopoongsan extracts help stabilize the emulsion. From the result of human patch test to assess the safety of cream containing Sopoongsan extracts, there was no stimulus of negative reaction on skin. In result of the user tests, it can be known that the higher concentration of the Sopoongsan was preferred by customers.

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.
