Abstract:

This paper segments the extractions of green colored cotton pigment by using normal phase chromatography, and researches the absorbance change in the visible region of the green fraction after UV irradiation. The green fraction is detected. Three kinds of components which have the same color and discoloration property with green colored cotton are found. Further confirms the multi-component characteristics of pigment in naturally green colored cotton. The experimental result shows that normal phase column is more effective for the separation of pigment in green colored cotton. 100% dichloromethane enrichment fraction is yellowish green which is absorbed around 665 nm and 400 nm. The absorption peak around 665 nm disappears after ultraviolet irradiation. This fraction mainly presents yellow.
