Dyeing Properties of Natural Red Colorants Extracted from Phytolacca americana Linne against Wool Fabrics
미국자리공으로부터 추출한 홍색색소의 모섬유에 대한 염색성
Abstract
Natural red colorants were extracted from Phytolacca americana Linne by using 50% ethanol solution at room temperature for 12 hours. The colorant components were partially purified as yellow and deep red colorants by thin layer chromatography. Natural red colorants were consisted of major water-soluble red colorant, having maximum absorbance at 538nm and alcohol-soluble yellow colorant, having maximum absorbance at 664nm. Concentration of red colorants were calibrated by the equation of dye(mg/ml)
