Indigo, as a blue pigment, has been known as one of the oldest natural dyes. Generally, natural dyes have moderate colors and are environmentally friendly, while harmful mordants must be used for fixing them and obtaining a full color range on fabrics and it is very hard to improve K/S of the dyeing and mordanting. In this study, single solid phase polygonum tinctroium dye was prepared by dorr agitator and lyophilization and physicochemical characterization of polygoum tinctoria dye substance was investigated by UV/VIS spectrophotometer, TLC, DSC, FT-IR spectrophotometer, 1H-NMR spectrophotometer, HPLC, MALDI-TOF mass, CHNS/O. Also cytotoxicity study of polygonum tinctroium dye was carried out MTT-assay. |
