Researches about various effective or functional compounds for cosmetics and human skin health have been performed and some of their results were applied to cosmetic production. In this study, the usefulness of water extract of mistletoe (Viscum album), white radish (Raphanus sativus), native mulberry (Cudrania tricuspidata), thistle (Cirsium setidens), and dandelion (Traxacum platycarpum) as a material for cosmetics based on contents of polyphenol and flavonoid, and activity for radical-scavenging, collagenase inhibition, elastase inhibition, and tyrosinase inhibition was qualitatively and quantitatively analyzed and compared. Extract of all materials was precisely adjusted to 20% (w/v) for quantitative comparison of each effective compound from each material. Polyphenol in the extract of R. sativus and C. tricuspidata were approximately 2,226 mg/kg and 2,538mg/kg, respectively, which were relatively higher than others. Flavonoid in the extract of R. sativus was approximately 188 mg/kg which was relatively higher than others. Radical (DPPH and ABTS)- scavenging activity of the extract of R. sativus, C. tricuspidata, T. platycarpum was approximately 2 times higher than others. Meanwhile, collagenase and elastase inhibition activities of C. setidens extract were approximately 123% and 126%, respectively, and tyrosinase inhibition activity of R. sativus was approximately 1,726% and 1,260%, respectively. On the basis of these results, extract from each material is required to be combined for making of multi-functional cosmetics.

The purpose of this study is to find out the effects of beauty salon management styles on the perception of beauty consulting. For this purpose, a survey was carried out on skin care specialists working at beauty salons in Seoul, Incheon, and Gyeonggi-do. The results of the study are as follows. first, after examining the interrelation between the skin care salon environment and perception of management style and skin care consulting, it was found to have a high positive correlation between skin beauty consulting perception and the skin care salons environment as well as management styles management resources, technical resources, and knowledge resources, in that order. Second, after examining the effect of skin care management style on beauty consulting perception, only the management resources of skin care salon environments and management style were found to have a significant influence on the perception of skin care consulting.

화색은 화훼 육종의 주요한 목표형질이다. 최근 유전공학 기술의 발달로 기존의 전통육종에서는 볼 수 없었던 파란장미와 파란카네이션과 같은 새로운 화색 개발이 성공적으로 보고되었다. 플라보노이드 생합성에 관해 축적된 지식기반 연구 결과를 바탕으로 새롭고 독특한 형질의 화색을 도입하는 것이 가능하게 된 것이다. 이러한 화색변경은 플라보노이드 대사경로의 조절, 즉 내재유전자의 발현조절 및 새로운 플라보노이드 합성 또는 특정 플라보노이드 합성을 위한 외래유전자의 추가도입과 플라보노이드 대사 전체를 조절하는 전사인자의 도입을 통해서 이루어져 왔다. 그러나 보다 실증적으로 이러한 플라보노이드 대사를 조절하기 위해서는 작물별 내재 플라보노이드의 조절 기작에 대한 이해를 바탕으로 목표로 하는 플라보노이드 합성을 위해 보다 정교한 대사흐름의 조절이 요구된다. 본 총설에서는 화훼작물의 화색변경 성공 예들을 자세히 소개하고 그 요인 분석을 통해 향후 더 성공적인 화색변경의 전략을 수립하는데 도움이 되고자 한다. Flower color is one of the main target traits in the flower breeding. Recently, technological advances in genetic engineering have been successfully reported the flower colors, such as blue roses and blue carnations that are impossible to develop by traditional breeding. Accumulated knowledge-based approaches for flavonoid biosynthesis enabled to introduce novel and unique colors into flowers. These flower color modifications have been made through the regulation of flavonoid metabolic pathway - control of endogenous gene expression and introduction of foreign genes to produce novel and specific flavonoids - and the introduction of transcription factors that are known to regulate sets of genes being involving in the flavonoid biosynthetic pathway. More empirical regulation of the flavonoids metabolism requires the understanding for regulatory mechanism of intrinsic flavonoids depending on the flower crops and the very sophisticated control of flavonoid metabolic flow. In this review, we summarized successf ul examples of flower color modification. It might be useful to deduce the strategy for the creation of exquisite colors in flower plants.
20대 여성의 얼굴피부를 대상으로 세 가지 약용식물 추출물을 함유하는 로션의 효능평가

The purpose of this study was to evaluate the effect of a natural cosmetics, which containing three medicinal plants (Viscum album, Cudrania tricuspidata and Cirsium setidens), on face skin of 20’S women using instrumental analysis technique. The females (study participants) who have used the product containing retinoids or steroids for the past one month, and who had any skin disease or pimples were excluded from this study. The effects of natural cosmetics were evaluated based on the degree of changes in skin conditions of the study participants, such as the number of pores, skin tone (brightness), pigmentations (number, area), flushes (number, area), and wrinkles in eye contour (right and left). Lotion A composed of only basic several cosmetic ingredients was used as a control product whereas lotion B composed of basic ingredients and three medicinal plant extracts were used as active product. Lotion B was more effective than lotion A for improvement of skin conditions, but skin tone and wrinkles in eye contour were not dramatically changed. These results showed that the three medicinal plant extracts employed in this study might be positive effect for skin care without any side effects. Thus, the extracts of Viscum album, Cudrania tricuspidata and Cirsium setidens might be useful as the raw material for making of natural cosmetics.
