한국산 산사자 추출물을 이용한 화장품 소재 개발 = Development of Cosmetic Material from Korean Crataegi Fructus Extract

다국어 초록 (Multilingual Abstract)

Objectives : This is the study of the application as the ingredients of cosmetics through the examination of the function for physiological activity of Crataegi Fructus, which has been used for herb medicines since ancient times.
Method : Korean Crataegi Fructus was extracted by water and ethanol and it was concentrated for the experiment materials. As the stability of the physiological activity function experiment, the effect of the electronic donating ability, antioxidative activity and UV scanning depending on various moisturizers has been researched for the development of cosmetic ingredients.
Results : The ethanol extract form Crataegi Fructus showed similar antioxidative activity, reaching 81.2% at 1000 ppm. As the result of UV scanning of each extract at 1000 ppm concentration and in UV 200~400 nm, it showed the similar absorbent peak (O.D: 0.7~0.8) to green tea extract, rosemary extract in UVB zone (280 nm) and the high optical density (1.8~2.4) in UVC zone. Propylene Glycol showed 71.8~75% antioxidative activity at 1mg/mL, and Glycerin showed 70.7%~71.8%, while 1,3-Butylene Glycol showed the safest antioxidative activity, reaching 79%~85%.
Conclusion : According to the result from the electronic donating ability measure of Normal skin-softener of the basic formulation, using 1,3-Butylen Glycol and various extracts from natural plants, it can be proved that Crataegi Fructus extract has the similar antioxidative activities degree of other extracts.
