        소목 (Caesalpinia sappan) 심재 추출물의 화장품 생리활성 연구

        황인숙 ( In Suck Hwang ),송연숙 ( Yeon Sook Song ),이근광 ( Keun Kwang Lee ) 한국미용학회 2012 한국미용학회지 Vol.18 No.3

        This study was performed to test cosmetic physiological activities of extracts extracted from the heartwood of Caesalpina sappan with hot distilled water and 70% ethanol. The results were as follows: Total polyphenol content was 77.25±0.01 mg% for the hot water extract and 36.68±0.02 mg% for the 70% ethanol extract. Total flavonoid content was 82.38±0.07 mg% for the hot water extract and 44.24±0.02 mg% for the 70% ethanol extract. DPPH electron donating ability against hot water extract was 79.58±0.05% and for the 70% ethanol extract was 46.91±0.03%. Tyrosinase inhibition activity was 60.20±0.02% for the hot water extract and 71.67±0.02% for the 70% ethanol extract. Toxicity for NIH3T3 cell strains was over 40 μg for both hot water and 70% ethanol extract, indicating increased levels of cell toxicity at the time of treatment. Antibiotic activity was extremely high for both the hot water and 70% ethanol extracts for the Gram-positive S. aureus KCCM 11593 bacterium and the Gram-negative P. aeruginosa ATCC 27853 bacterium. Antibiotic activity showed a particular tendency of increase in the ethanol extract for E. coli KCCM 11234.

        소목(Caesalpinia sappan) 심재 추출물의 모발 염색특성 연구

        황인숙 ( In Suck Hwang ),송연숙 ( Yeon Sook Song ),이근광 ( Keun Kwang Lee ) 한국미용학회 2012 한국미용학회지 Vol.18 No.4

        The purpose of this study was to investigate the hair dyeing properties of extracts developed from the heartwood of Caesalpinia sappan with hot distilled water solution and to examine the degree of coloration from application of the resulting natural dyes to discolored artificial hair. The results were as follows: The color of the C. sappan heartwood extract was found to be influenced by pH. Higher acidity generally led to a stronger yellow tint, while higher alkalinity led to a decrease in yellow coloration and a stronger reddish tint. Dyeing with the C. sappan heartwood extract resulted in a visible redness to the artificial hair, with some variation in color according to mordancy. Thus, hair treated with KAl(SO4)2·l2H2O fixative showed a deep brown color, and hair treated with FeS04·7H2O after mordant showed a color that was similar to black to the naked eye but was actually a deep celadon green. Dyeing of artificial hair with C. sappan heartwood extract was found to vary slightly according to dyeing period and pH. Shampoo fastness following C. sappan heartwood dyeing was found to vary slightly according to the performance or nonperformance of fixative treatment and the type of fixative used.
