Traditionally, dyes extracted from onion shells have been used as natural pigments but dyeing methods with reproducibility have not been developed. In this study, the dyes were analyzed by high performance thin layer chromatography(HPTLC) to obtain the ratio of pigments in water and ethyl acetate extract. Furthermore, the present study was also carried out to obtain the information characteristic of wavelength which proportionally decrease for continuous dyeing reaction. Scanning of water extract showed 4 peaks by the mobile phase of benzene/ethyl acetate/acetic acid(40/10/5) and the peak 1 exhibited yellow color with the maximal absorption spectra of 306nm and 309nm while ethyl acetate extract showed 9 peaks in the same mobile phase. The water extract after ethyl acetate extraction was adjusted to 0.5 of O.D.(optical density) at 550nm by adding of water and compared wavelength of the pigments from 200 to 600nm to find the proportional decrease of wavelength. As the result, it showed that wavelength of 306nm could be the standard of dyeing monitoring points. |
