To develop a new anti-skin aging cosmetics or functional foods by using antioxidative activity and collagenase inhibitor, a potent collagenase or elastase inhibitor was screened from various extracts of medicinal plants and its optimal extraction condition was investigated. And antioxidative activity, antimicrobial activity and inhibitory of effect against collagenase activity were investigated. In the these results, we selected the Sanguisorba (Sanguisorba officinalis L.) that presents a potential biological activities. Sanguisorba which is very rich in triterpenoid saponin and tannins was recently reported its anti-oxidant activities and phytoestogenic activities in vivo test and many clinical studies. The experiments were carried out in vitro to determine anti-oxidant activities of Sanguisorba extracts on DPPH radical scavenging activity assay, Superoxidase scavenging activity assay, Elastase and collagenase activity assay. It show that the Sanguisorba extracts have the most significant anti-oxidant on free radical scavenging activity assay, and also inhibited significantly activities of elastase, collagenase. Further, Sanguisorba extracts are activated Type I collagen protein expression in CCD-986sk cells. These result suggest that the Sanguisorba extracts on DPPH radical scavenging activity assay, Superoxidase scavenging activity assay, elastase and collagenase activity assay, Type I collagen protein expression in CCD-986sk cells effected could be developed cosmetic ingredients for anti-aging.

$Sun{\sim}Si{\sim}Miao$(孫思邈) is known to everybody as a great medical doctor. He has written two famus books. Those are the $Qian{\sim}Jin{\sim}Yao{\sim}Fang$(${\ll}$千金要方${\gg}$) and the $Qian{\sim}Jin{\sim}Yi{\sim}Fang$(${\ll}$千金翼方${\gg}$). He said that woman's disease differ from man's disease, we must care of woman carefully. And he has written seven parts of the books on gynecology. He has introduced reason of woman' disease and method of medical treatment variously. Also he has introduced a method of making cosmetics and beauty treatment. So We summarized pediatrics theory in two books and decomposed reason of disease and method of medical treatment. Also I compared with $Xiao{\sim}Pin{\sim}Fang$(${\ll}$小品方${\gg}$) In conclusion, I have known that $Sun{\sim}Si{\sim}Miao's$ gynecology is consist of useful and various substance.

Objectives : The present study was designed to investigate effects of Ssanghwa-tang (Shu$\bar{a}$nghu$\bar{a}$-g$\bar{e}$ng) on oxidation/reduction reaction-related and aging-related enzymes $in$ $vitro$. Methods : We performed MTT assay, collagenase inhibition assay, elastase inhibition assay, tyrosinase inhibition assay, DPPH free radical scavenging assay, SOD-like activity and xanthine oxidase (XO) inhibition assay. Results : The 50% ethanol (EtOH) extract of Ssanghwa-tang (SHT) showed 55% inhibition of collagenase activity, and 42% inhibition of elastase activity at 1 mg/ml concentration. Also it's treatment showed 18% inhibition of tyrosinase activity, to relate whitening effect, at the same dose of 50% ethanol extract of SHT. Antioxidant activities were determined by DPPH radical scavenging, XO inhibiting activity and SOD-like activity. These scavenging, XO-inhibiting and SOD-like activities were measured in 80%, 75%, and 28% inhibitions, respectively, at a 1 mg/ml treated dose, compared to those of control. The inhibitory effects of 50% EtOH extract on aging and oxidation-related enzyme activities were higher than those of water extract and 95% EtOH extract. Conclusions : Taken together, our findings suggest that the SHT has potential and applicable benefits for development of cosmetics to have anti-aging (anti-wrinkle and whitening) and anti-oxidation functions.

In this study, extracts of bark from Ulmus davidiana var. japonica and its fractions were investigated the antioxidative, antibacterial and tyrosinase inhibition activity for physiological activity towards functional applications. In the measurement of DPPH radical scavenging activity, the ethyl acetate fraction showed higher radical scavenging ability than others. Moreover, in the tyrosinase inhibition assay, showed that the ethyl acetate fraction has good inhibition effects. Results of the DPPH radical scavenging and tyrosinase inhibition activity are related with the total polyphenol concentrations of ethyl acetate fraction. In antibacterial activity used to find out by utilizing the disc diffusion assay, chloroform fraction showed strong effect against Staphylococcus aureus and S. epidermidis. These results are related with the flavonoid contents of chloroform fraction. On the other hand, in the L929 cell viability measurement by MTT assay, the hexane, butanol and aqueous fraction treated at high concentration were showed cytotoxicity. But the others samples were exhibited a moderate viabilities. As a result of investigated the antioxidant and tyrosinase inhibition activity, the ethyl acetate fraction could be applicable for cosmetics related fields. And the chloroform fraction showed significant antibacterial activity against S. aureus and S. epidermidis.

오미약성 이론은 다섯가지 맛 중에서 적어도 하나 이상을 맛을 포함하는 다양한 허브로 구성되어 있으며, 이러한 이론은 인간의 질병을 예방하고 면역 체계를 강화하는데 사용되어왔다. 본 연구의 목적은 오미약성 이론에 근거한 단일 추출물 및 혼합 추출물의 효능 차이와 성분 변화를 확인하는 것이다. 황련, 승마 및 백복령 세가지 약초를 선택하였고 단일 추출물 및 혼합 추출물의 약리학적 효능을 평가하였다. 결과적으로 혼합추출물은 단일추출물과 비교하여 400 ug/mL 농도에서 우수한 세포 이동 효과를 보였다. 또한 혼합추출물은 수지상세포의 활성을 증가시켜 면역을 강화시켰으며 DPPH assay 및 HPLC-ABTS assay를 통해 가장 높은 항산화 활성을 보였다. 이번 연구에서 우리는 한의학적 이론을 접목하여 화장품 및 의약품 분야에 응용 가능한 새로운 소재를 개발하였다.

Polysaccharide (PS) was fractionated from hot-water extract of Artemisia iwayomogi Kitamura stems. PS showed considerably higher hydroxyl radical scavenging activity than caffeic acid and glutathione. PS showed lower superoxide anion radical scavenging activity than hydroquinone and ascorbic acid. The scavenging activity of PS on the reactive oxygen species (ROS) induced by human neutrophils with zymosan was determined by the lucigenin-enhanced chemiluminescence assay. The scavenging effect of the PS on ROS as determined by the chemiluminescence assay was about 2-fold stronger than that of ascorbic acid at the same concentration. PS significantly decreased protein carbonyl and malonaldehyde contents in UVB irradiated skin homogenates, which was comparable to glutathione at the same concentration. This result suggested that PS derived from A. iwayomogi Kitamura stems may be a potent candidate as functional compound for the protection on UVB induced skin damage in cosmetics.

The purpose of this study was to investigate the effect of the aqueous extract of the Astragalus membranaceous(AM). AM showed inhibitory effect on the tyrosinase activity using L-tyrosine as a substrate. Tyrosinase plays an important role in the process of melanin polymer biosynthesis. In vitro AM extract(1mg/ml) inhibited melanin biosynthesis and are useful for the material used in cosmetics. B16 mouse melanoma cells were cultured in different concentrations. The non-cytotoxicity of the plant extracts was confirmed by MTT assay.

To investigate the clinical aspects of CHT in atopic dermatitis (AD) treatments, the effect of CHT in anti-oxidative and anti-inflammatory cytokines were tested. 100% or higher cell viability was observed in all tested groups from 25 to 200 ${\mu}g/m{\ell}$ using Raw 264.7 cells. CHT showed dose-dependent DPPH scavenging activity, with more than 90% scavenging activities at 800 ${\mu}g/m{\ell}$ concentrations. CHT showed dose-dependent suppression activity of ROS production, especially at 200 ${\mu}g/m{\ell}$ of 37.5%. CHT decreased NO production activity, with significant decrease of 33.2% at 200 ${\mu}g/m{\ell}$. IL-6, MCP-1, TNF-${\alpha}$ production rate were decreased by approximately 25% when Raw 264.7 cells were treated with LPS and with CHT of 200 ${\mu}g/m{\ell}$. Also, IL-$1{\beta}$ production rate was decreased by 25% at 100 ${\mu}g/m{\ell}$. The results above indicate that CHT significantly reduces the effect of oxidative and inflammatory cytokines. The use of CHT in dermatitis can be widely suggested.

Artemisia princes var. orientalis의 수용성 추출물이 식품, 화장품, 의약품 등의 항균제로 이용될 수 있는지에 대해 연구 하였다. 순수한 물을 이용한 추출물에서는 항균성을 찾기 힘들었고, 쑥의 줄기와 잎 부분에서 메탄올로 추출한 후 물로 추출한 물이 Staphylococcus aureus에 대해서 항균성을 크게 나타냈으며, 잎이 줄기 부분보다 더 큰 항균성을 나타냄을 확인했다. 항균성을 갖는 물질을 밝혀내기 위해 쑥의 주된 항균 성분이라 알려진 caffeic acid와 비교 실험을 하였다. UV 특성곡선에서 caffeic acid와 유사한 phenolic compound의 profiling은 확인할 수 있었으나 caffeic acid의 disc diffusion method를 이용한 실험에서는 항균능력을 나타내지 않았다. 물질규명을 위해 추출물을 세 부분으로 분획 하였고, 이 중에서 Staphylococcus aureus에 대해 항균성은 UK 2에서 크게 나타났다. 본 연구는 Artemisia princeps var. orientalis 의 메탄올 후 물 추출물이 항균제로써의 가능성을 알아봄으로써 식품 또는 화장품의 보존료나 항균제의 이용성이 있음을 충분히 확인하였다.
